ALT 6 Hedge Funds
A hedge fund is a private pooled investment vehicle that raises capital from institutions and high-net-worth individuals and puts it to work across a wide range of markets: equities, fixed income, currencies, derivatives, private capital, and real assets. What sets a hedge fund apart is not the instruments it holds but the way it invests. Two funds can own the very same securities, yet only one counts as a hedge fund, because it combines those holdings with leverage, short selling, and derivatives to shape a return profile the underlying assets would never produce on their own.
The label is something of a historical accident. The earliest funds paired long and short equity positions so that broad market moves largely cancelled out, leaving the manager’s security selection as the main driver of returns. Modern hedge funds are no longer tied to equities or to hedging, so the name now covers a broad family of approaches rather than a single technique.
The objective is high return, measured either in absolute terms or relative to the fund’s own volatility. Because their strategies do not map neatly onto a stock or bond index, many hedge funds gauge themselves on an absolute return target rather than by tracking any index. Their returns also tend to show low correlation with traditional assets, which is a large part of the appeal for a diversified portfolio.
Several of the tools a hedge fund uses, borrowing to invest, layering on derivatives, and selling short, look on the surface as though they add risk rather than remove it. The resolution is that the strategy divides the portfolio so that one leg offsets the risk in another. By neutralising unwanted market exposure internally and managing the pieces against each other, the manager aims for a better risk-adjusted return than any single position would give.
How hedge funds differ from other vehicles
Hedge funds and mutual funds both invest client money in pursuit of a better balance of risk and reward, but they part ways on several points:
- Mutual fund managers earn a fixed fee and need not invest alongside clients. Hedge fund managers earn a performance-based fee, and many are required to commit their own money to the fund.
- Mutual funds are heavily regulated because they are sold to the public. Hedge funds are lightly regulated and open only to institutional and accredited investors.
- Some hedge funds apply a high-water mark, paying the manager a performance fee only when the fund climbs above its previous peak value.
Set against exchange-traded funds, bond funds, and REITs, the hedge fund stands out as privately owned and lightly regulated. It also differs from a private equity fund: hedge funds work on a shorter horizon and hold more liquid assets, whereas private equity locks capital into private operating companies for years.
A hedge fund may concentrate on a single asset class or blend several, and it may focus on one region or roam globally. Leverage, obtained through short selling, outright borrowing, or derivatives, is a common ingredient, which means the fund has to watch the value of its exposures continuously, above all when both the long and the short side are built entirely from derivatives.
Classifying hedge funds by strategy
Since a hedge fund is defined by its approach, the natural way to sort the universe is by strategy. Classification lets investors compare aggregate performance, choose strategies to combine, and pick sensible benchmarks. One common scheme uses five broad groups:
- equity funds,
- event-driven funds,
- relative value funds,
- opportunistic funds, and
- multi-manager funds.
Not every fund shorts securities or uses leverage; many simply mine a niche of expertise in a sophisticated way. And for investors who lack the resources to select and monitor individual funds, a fund of hedge funds assembles a ready-made diversified portfolio.
| Equity | Event Driven | Relative Value | Opportunistic | Multi-Manager |
|---|---|---|---|---|
| Long/Short Equity | Merger Arbitrage | Convertible Bond Arbitrage | Global Macro | Fund of Funds |
| Short Biased | Distressed | Fixed-Income Arbitrage | Managed Futures | Multi-Strategy |
| Market Neutral | Special Situations | Multi-Strategy | ||
| Activist |
The five broad categories break down into strategies defined by the instruments used, the trading philosophy followed, and the risks taken on. The four families examined most closely at this level are equity, event-driven, relative value, and opportunistic.
Equity strategies
Hedging a long book with short sales is the original hedge fund idea. Long/short equity funds trade public equities and equity derivatives on both sides of the market. Most begin from the bottom up, analysing the company first, then its industry, then the wider market, and hold reasonably balanced long and short exposures. A top-down manager reverses that order, starting with the global macro picture before drilling into sectors and single names, or simply times the market. Shorts may be single names chosen for alpha or index positions used to strip out market risk.
- Fundamental long/short. Buy companies trading cheaply relative to intrinsic value (through shares or call options) and short those that look expensive, expecting the gap to reverse. These managers usually keep a net long position but flex the amount of market exposure with their view. A long bias is what separates this from a short-bias strategy.
- Fundamental growth. Use fundamental analysis to find companies set for high growth and capital appreciation, go long those, and short firms whose business models face downward pressure and probable decline. What drives the outcome is how far growth expectations diverge from value expectations. These books tend to end up long biased, so they are not market neutral and carry a non-zero beta.
- Fundamental value. Buy undervalued, unloved companies where a turnaround could lift revenue, cash flow, and valuation. Performance here is powered by the gap running the other way, value expectations set against growth.
- Short biased. Use quantitative, technical, and fundamental work to short overvalued shares, with limited or no long exposure. Managers often dig forensically for hidden accounting or business flaws, expecting the price to fall. They vary short exposure over time and tend to be contrarian, betting against otherwise admired companies. Such funds can steady a larger portfolio during market stress, though sustaining long-run returns has been hard across three decades of mostly rising markets.
- Market neutral. Go long undervalued and short overvalued securities while holding the net market position, and therefore beta, close to zero. The aim is to profit as individual securities re-rate without riding the overall market. Leverage is often needed to turn small, stable, single-digit returns into something meaningful, which raises risk during unexpected volatility unless the fund reduces its leverage.
Tenderledge Investments, which runs a fund of hedge funds, benchmarks four equity strategies against a market index (the S&P 500) using ten years of monthly returns. The statistics and the correlation matrix are below.

Event-driven strategies
Event-driven strategies are bottom-up bets on defined corporate events, an acquisition or a restructuring, that are expected to reset valuations. Positions can be long or short and span common stock, preferred stock, debt, and options. Hedge Fund Research subdivides the group:
- Merger arbitrage. Buy the target’s stock at a discount to the announced takeover price and short the acquirer’s stock once the deal is public. Profit arrives as the deal spread narrows to the closing terms; shorting the acquirer also expresses the risk that it overpays. The main danger is that the combination fails and the holdings fall before the position can be unwound. Because the spread is modest, leverage is common, which magnifies both the gain and the loss when a deal collapses.
- Distressed and restructuring. Focus on the securities of companies at or near bankruptcy. One route buys discounted fixed-income securities senior enough to be covered by corporate assets, expecting them to recover toward par in a reorganisation or liquidation. Another buys a debt instrument, the fulcrum security, likely to convert into new equity after restructuring, then holds or sells that equity.
- Special situations. Target companies acting on a catalyst: issuing or repurchasing securities, making special capital distributions, taking rescue finance, or selling and spinning off assets.
- Activist. Short for activist shareholder. Build a stake large enough to win a board seat and steer corporate policy, pushing for divestitures, restructurings, distributions to shareholders, or changes in management and strategy. Unlike private equity, activists work mainly in the public equity market.
These strategies lean long biased, with merger arbitrage the least biased of the group. A merger usually completes in 6 to 24 months, while a bankruptcy or reorganisation can drag on for years.
Carl Icahn, an activist manager, has repeatedly made money by taking large stakes and steering operations. He began buying Hertz in 2014, convinced the car rental group had a strong brand but weak discipline, and built a position above USD1.1 billion by the end of that year. He installed new directors and management, who restored fiscal and operational order over the following years. By 2020 he held more than 55 million shares, about 39 percent of the company, worth roughly USD2.3 billion before the crisis. When COVID-19 and the collapse in travel pushed Hertz into bankruptcy protection in May 2020, he sold at a loss of about USD2 billion, having bought 11 million shares only weeks earlier. Hertz emerged from bankruptcy in July 2021. The episode shows both the influence an activist can wield and the tail risk that even a skilled manager carries.
A money manager reviews the automobile sector and judges that General Motors is overvalued relative to Ford. She goes long 100 Ford shares and sells short 150 GM shares. Her view proves right, and at quarter end she unwinds both positions at a profit.
A fundamental long/short manager is choosing positions for the portfolio.
Relative value strategies
Relative value strategies profit from a temporary pricing gap between related securities, betting that the anomaly corrects over time.
- Convertible bond arbitrage. A broadly market-neutral trade that exploits mispricing between a convertible bond and its parts, the straight bond and the embedded call option. The manager typically buys the convertible and shorts an amount of the issuer’s common stock set by the option delta. Bankruptcy risk can be hedged with equity put options or credit default swaps on the issuer.
- Fixed income (general). Relative value within fixed income, weighted toward sovereign debt (relative value rates) and sometimes investment-grade corporates (relative value credit). Trades pair different issuers, corporate against government, different layers of one issuer’s capital structure, or different points on a single issuer’s yield curve. Spread moves, currency dynamics, and the slope of the government curve drive the performance.
- Fixed income (asset backed, mortgage backed, and high yield). Relative value among higher-yielding instruments: asset-backed and mortgage-backed paper, high-yield loans, bonds, and the derivatives on them, chasing a well-secured coupon and mispricings in quality and security.
- Multi-strategy. Pursue relative value both inside a single asset class and across several, rather than committing to one type of trade. Separate pods of managers run different approaches, and the lead manager deploys and redeploys capital quickly between them as conditions change.
Opportunistic strategies
Opportunistic funds trade around macro events and commodities, often using index ETFs or derivatives alongside individual securities.
- Macro strategies. Top-down bets on economic trends, trading fixed income, equities, currencies, and commodities on a view of where major variables are heading. Long and short positions express a call on overall market direction as it responds to major trends and events. Because these funds benefit most from higher volatility, aggressive action by central banks to smooth out shocks tends to shrink their opportunity set.
- Managed futures (CTAs). Actively managed, diversified directional positions taken mostly in futures markets on technical and fundamental signals. Known as commodity trading advisers for their commodity roots, CTAs now trade futures on equities, fixed income, and currencies too, using models that read trend and momentum over several horizons. They can diversify a portfolio, especially in strongly trending or stressed markets, and can profit from short positions in falling markets. Their weakness is mean-reverting markets, where false breakout signals produce extended drawdowns before a real trend appears; their diversification value has also thinned as many have migrated toward financial futures.
Commodity-focused managed futures have a feature global macro lacks: a constant tension between suppliers and consumers, since expensive commodities depress demand (which pulls prices down) while cheap ones curb supply (which pushes prices back up). That built-in balance has no clear parallel in traditional stocks and bonds.
Seven features set hedge funds, and the strategies they run, apart from traditional investments:
- Fewer legal and regulatory constraints.
- Flexible mandates that permit shorting and derivatives.
- A larger investable universe.
- Aggressive styles that allow concentrated positions carrying credit, volatility, and liquidity risk premiums.
- Relatively liberal use of leverage.
- Liquidity constraints such as lockups and liquidity gates.
- Relatively high fees, combining a management fee and an incentive fee.
Even when a hedge fund buys the same listed shares or bonds as a mutual fund and values them with the same financial-statement tools, its risk and return come out differently. A typical relative value fund mixes long and short equity positions, adds borrowed money, and takes opportunistic positions in special situations, producing a profile a long-only fund cannot match.
Lockups, gates, and redemption terms
Because they answer to lighter disclosure rules, hedge funds can pursue ideas that need time to pay off, ideas unsuited to a mutual fund promising daily liquidity. Investors accept a lockup period during which they cannot withdraw, followed by a notice period before a redemption can be processed. A liquidity gate lets the fund cap total redemptions so it can sell assets gradually rather than at fire-sale prices. Set against a mutual fund that may allow redemption on one day’s notice, these terms give the hedge fund far more room to operate.
A redemption fee is sometimes levied, and it usually goes to the fund rather than to the manager, shielding the investors who stay, especially when someone leaves during the lockup. This arrangement, a soft lockup, offers a path to early redemption, at a cost.
Lighter constraints also let hedge funds hold less liquid, less scrutinised positions whose true value is at times opaque. Long/short, activist, distressed, and arbitrage books are often concentrated, leveraged, and long-lived; building them takes time and unwinding them can be slow and awkward, above all when markets are briefly under stress. Redemption restrictions exist precisely to manage that risk.
Fees, incentives, and oversight
The reduced transparency of complex strategies creates asymmetric information between manager and investor. Incentive-based performance fees are the bridge: by sharing in the upside, the manager is pushed to act in the investors’ interest. Hedge funds are often seen as riskier from a fraud-oversight angle, yet some actually take less outright market risk than the registered products available to retail investors, so their regulatory risk and illiquidity risk can be confused with market risk. Choosing a fund therefore means examining the general partner’s operational framework, risk management, and hands-on monitoring, along with manager experience, fiduciary standards, and alignment of interests. Reported frauds, from Ponzi schemes to falsified performance, and strategies that unravelled in turmoil are reminders that light oversight and high minimums can invite abuse, so strategy, transparency, liquidity, reporting, track record, and fee arithmetic all deserve close scrutiny.
In January, HedgeAway, a new hedge fund, starts with USD100 million. It charges a 1.6% management fee based on end-of-year value and an 18% performance fee on gross returns, charged only on the amount above an 8% hurdle rate, after fees. The fund ends the year with assets under management of USD120 million.
A hedge fund is usually organised as a private investment partnership, onshore or in a tax-advantaged offshore centre, with access often limited to a set number of investors who meet income and net worth tests. Legally it is usually a limited partnership or limited liability company run by a general partner or managing member, who serves as the hedge fund manager. That partnership or managing member draws a management fee, while the general partner is compensated on performance. Investors buy a share of the fund and receive their slice of the returns net of fees. The private placement memorandum, the partnership agreement, and the articles of incorporation set the legal and contractual terms and the operating framework. On paper these entities are perpetual, though in practice funds close and are wound up on a regular basis.
Direct forms
A widely used direct form is the master feeder structure. An offshore feeder and an onshore feeder both channel capital into a single master fund, which does the investing under its partnership agreements. Pooling in this way builds economies of scale, welcomes global investors with relative ease, and sidesteps a number of regional regulatory hurdles. It does not, however, let an investor in a taxable jurisdiction escape tax simply by routing money through the offshore feeder.
The classic fee arrangement is two and twenty: the operating partnership takes a 2% management fee, and the general partner keeps 20% of net profits, with the remainder flowing back through the feeders to investors. Under pressure from investors, newer structures have appeared, such as one or thirty, under which the manager takes whichever is larger, a 1% management fee or an incentive equal to 30% of the fund’s alpha (its outperformance against a benchmark), in place of a charge tied simply to total profits.
Alongside the partnership agreement, a hedge fund may issue a side letter to meet one investor’s particular legal, regulatory, tax, operational, or reporting needs. A side letter complements, and can occasionally supersede, the main documents, and is used when an investor wants a concession, such as enhanced information rights, without amending the memorandum or the articles.
Large investors may instead choose a fund built for a single investor, or a separately managed account (SMA). A fund of one is a hedge fund built for a single investor. In an SMA the investor owns the vehicle and holds the assets in the investor’s own name, while delegating day-to-day management to the hedge fund manager. An SMA offers a customisable mandate, better transparency, efficient allocation, higher liquidity, more control, and often lower fees. The trade-offs are greater operational complexity and heavier governance, and because the manager holds no personal stake and may steer only the most liquid trades to the account, the manager’s incentive can weaken, which structuring the fee toward incentives helps offset. These accounts therefore suit larger, institutional investors.
Indirect forms
Indirect routes widen access for smaller institutions and larger retail investors, or for those who lack the skill to manage a given asset type or who want several strategy exposures at once, often to lower costs, improve transparency, and raise liquidity. The usual choice is a fund of hedge funds, a managed portfolio of hedge funds.
A fund of funds pools investor capital and spreads it across many hedge funds, giving diversification across strategies, regions, and management styles, generally with lower minimums, shorter lockups, and better exit liquidity. The cost is another layer of fees, often an extra 1% management fee plus a 10% incentive fee on top of the underlying funds’ charges, with that incentive normally computed on profits after management fees are stripped out at each level. Fee layering trims the investor’s gross return and can mean paying more than once to manage the same assets, but it buys access to funds that might otherwise be closed and to professional due diligence and monitoring, and the manager can often negotiate better redemption and fee terms than an individual could. The catch is that the greater liquidity of a fund of funds can force selling during turmoil and weaken performance.
Example 3 below illustrates how a fund of funds relates to individual strategies. Tenderledge, benchmarking annual strategy returns over ten years, finds the highest correlation of its fund-of-funds returns with fundamental growth and the lowest with short-bias funds.
| Strategy | Correlation with fund of funds |
|---|---|
| Fundamental Growth | 0.91 |
| Convertible Arbitrage | 0.89 |
| Distressed/Restructuring | 0.84 |
| Multi-Strategy | 0.83 |
| Credit | 0.74 |
| Equity Market Neutral | −0.02 |
| Macro/CTA | −0.16 |
| Short Bias | −0.84 |
A growing set of exchange-traded products aims to mimic hedge fund styles without owning any hedge funds. Using quantitative tools and liquid assets, these replication ETFs aim for returns that track strategies like market neutral, long/short equity, and event-driven closely (Example 4 describes exactly such a product built to track a fund-of-hedge-funds index). They usually return less than the real strategies, because they are publicly traded, more heavily regulated, cannot restrict redemptions, and cannot lever up as far; in exchange they offer more liquidity, lower fees, and more transparency.
Match each investor to the most appropriate structure among a fund of funds, a separately managed account (SMA), and managed futures.
Hedge funds generate returns differently from traditional portfolios. A long-only fund earns most of its return by bearing systematic market risk, beta, while diversifying away security-specific risk. A hedge fund does close to the reverse: it limits market exposure and hunts idiosyncratic return, or alpha, drawn from market inefficiencies (often short-lived) and the manager’s skill in exploiting them.
Performance breaks down into three separate sources:
- Market beta, the broad market return an index fund or ETF could capture.
- Strategy beta, the return attributable to the fund’s strategy applied across the market.
- Alpha, the manager-specific return from selecting particular positions.
Managers earn strategy beta and alpha by spotting mispriced securities and sectors, timing markets, influencing a company’s business model, and using leverage to amplify results. None of this says traditional asset pricing models are wrong; those models assume efficient markets, and hedge fund returns come from systematic and idiosyncratic risk factors the models leave out. Investors rarely keep the full return, because high fees eat into alpha, and a fund that closes for poor performance may return redeemed capital at a reduced value, cutting the total further.
Reading hedge fund indexes with care
To compare risk-adjusted performance, analysts use hedge fund indexes built from publicly available data. Because reporting is voluntary and self-reported, several biases push the picture upward:
- Selection bias. Funds are sorted into strategy peer groups inconsistently, sometimes by prospectus, sometimes by historical style, sometimes both, and each choice compounds the distortion. Providers also differ on inclusion rules covering asset size, vintage, and whether the fund still admits new money.
- Survivorship bias. Dropping funds that stopped reporting, often the poor performers, lifts the index. Including funds of funds that keep reporting, both active and closed, softens the effect.
- Backfill bias. When a fund reports for the first time, its strong past record is filled in, and since mainly winners report, the index overstates history. Larger indexes suffer less of this.
Many hedge fund indexes are equally weighted rather than asset weighted, so comparing large and small funds against a size-weighted view can mislead. Data also arrive with a lag of about four weeks, and because the indexes are non-investable and illiquid, they are hard to replicate.
Reporting to a hedge fund index is voluntary, and a manager consistently trailing the peer group has little reason to keep advertising the fact, especially while raising money or launching new funds. Selection, survivorship, and backfill bias therefore all point the same way: reported hedge fund performance is likely overestimated. That is one reason risk and return are usually measured against fund-of-funds composite indexes, which reflect the actual performance of portfolios of funds and are themselves investable.
Historical risk and return
Since 1990, hedge funds, proxied by the HFRI Fund of Funds Composite Index, have delivered higher returns than stocks or bonds before fees, with volatility close to that of bonds. The measures may read a little low because of the extra fee layer, and they tend to tilt toward equity long/short, a large part of most funds of funds, but they offer a fairer and more conservative estimate of average hedge fund performance.
| Fund of Funds | Global Stocks | Global Bonds | |
|---|---|---|---|
| Annualized return, 1990–2014 | 7.2% | 6.9% | 6.3% |
| Annualized return, 2015–2019 | 2.48% | 10.41% | 2.42% |
| Annualized volatility, 1990–2014 | 6.0% | 16.5% | 5.8% |
| Annualized volatility, 2015–2019 | 1.08% | 11.42% | 1.33% |
| FoF correlation with column, 1990–2014 | 0.56 | 0.07 | |

| Worst drawdown | −22.2% | −54.6% | −10.1% |
FoF: HFRI Fund of Funds Composite Index. Global stocks: MSCI ACWI Index. Global bonds: Bloomberg Barclays Global Aggregate Index.
Over 1990 to 2014, hedge funds beat both asset classes with bond-like volatility and modest correlation to global stocks (0.56) and negligible correlation to global bonds (0.07). The 2015 to 2019 window tells a different story: fund-of-funds returns fell well behind global equities, while their correlation with equities rose to 0.86, which made hedge fund allocations less useful and less popular. Some allocators still hold or add them as a bond-market substitute.
Another way to weigh the trade-off is the coefficient of variation of annual returns, which this reading treats as relative return adjusted for risk.
An analyst is evaluating why some funds never appear in a hedge fund index.
Diversification benefits
The original market-neutral strategy set net market sensitivity to zero, using long and short positions to create value with minimal market exposure. Strategies have since spread across asset classes, but market-neutral, relative value, and event-driven funds still tend to beat equities in downturns and when single-stock correlations fall, and to lag when correlations are high and shares rise together. Their diversification value first stood out when the dot-com bubble unwound in 2000 to 2002, grew through funds of funds, and expanded into direct allocations after the 2008 crash, when investors chasing uncorrelated risk-adjusted returns, not outsized upside, accepted high fees for diversification and risk mitigation. The 2008 crisis, including the Lehman Brothers bankruptcy and the Bernie Madoff fraud, forced far more due diligence; the higher-quality institutional and pension money that followed demanded transparency and control, which favoured the best funds while many others failed to keep pace with the strong markets of 2009 to 2019.
Hedge fund returns still correlate weakly with traditional asset classes such as bonds and cash, so for those investors they bring diversification and steadier results over the long run. Placing hedge funds into a standard 60/40 portfolio typically lowers total standard deviation and lifts the Sharpe ratio, improving both diversification and risk-adjusted return.
| Hedge Funds | S&P 500 | Investment-Grade Bonds | |
|---|---|---|---|
| Hedge Funds | 1 | 0.82 | 0.10 |
| S&P 500 | 1 | −0.06 | |
| Investment-Grade Bonds | 1 |
Hedge funds: Dow Jones Credit Suisse Hedge Fund Index. Investment-grade bonds: Bloomberg Barclays US Aggregate Bond Index.
The matrix confirms the pattern: hedge funds show a fairly high correlation with equities (0.82) but only a weak link to investment-grade bonds (0.10). The diversification case rests mainly on that weak link to bonds, and, as the shifting correlations across time periods show, the benefit can vary, so careful manager due diligence remains essential.
