Quick Navigation
I've spent over a decade studying hedge funds and even managed a small long/short book for a family office. In that time, I've seen people throw around terms like "global macro" and "event driven" without really understanding what happens inside those black boxes. Today I'm going to walk you through the five main hedge fund strategies — not textbook definitions, but the gritty reality of how they work, where they shine, and where they blow up.
1. Long/Short Equity
This is the granddaddy of hedge fund strategies. The idea is simple: buy stocks you think will go up (long) and sell stocks you think will go down (short). The net exposure can be anything from 30% long to 150% long depending on the manager's conviction.
I worked at a long/short fund focused on technology in 2018. We were long Microsoft and short a few overhyped SaaS companies. The beauty of pair trades — when your long and short are in the same sector — is that you remove market beta and isolate stock selection skill. When the whole market tanked in Q4 2018, our long positions fell but our shorts rallied, so we barely lost money.
Where it works: In choppy or sideways markets where stock pickers can add value. Where it fails: In strong bull markets when shorts keep getting squeezed (think 2020-2021).
Sub-strategies to know
- Sector-specific: Focus on one industry like healthcare or energy.
- Market neutral: Targets zero net exposure — all returns come from stock picking.
- Variable bias: Manager shifts net exposure based on market outlook.
2. Event Driven
Event driven managers bet on corporate events: mergers, spin-offs, bankruptcies, activist campaigns. The idea is that when a company announces a deal, the stock price doesn't immediately reflect the final outcome. There's a spread — and if you can predict the outcome better than the market, you make money.
I once watched an event-driven fund make 15% in three months on a merger arbitrage deal. Company A announced it would buy Company B for $50 per share. B's stock shot up to $48, but then regulatory concerns pushed it down to $44. The fund bought heavily at $44, calculated the probability of approval at 85%, and waited. The deal closed, and they collected the spread.
Where it works: When there's deal uncertainty that creates mispricing. Where it fails: When a surprise regulatory veto kills a deal — like the failed Sprint/T-Mobile merger in 2014 that caused a 20% loss in one day.
| Event Type | Typical Return Profile | Risk Factor |
|---|---|---|
| Merger Arbitrage | 3-8% annualized | Deal breakup |
| Distressed Debt | 10-20% if successful | Legal delays, liquidation |
| Activist Investing | Highly variable | Board resistance, proxy fights |
| Spin-offs | 5-12% | Market sentiment, execution risk |
3. Global Macro
Macro managers take bets on entire economies: interest rates, currencies, commodities. They don't care about individual stocks — they care about the big picture. Think George Soros breaking the Bank of England or Ray Dalio's "all-weather" portfolio.
I sat in on a macro fund's morning meeting once. The CIO started with a map of global central bank balance sheets. He pointed at the Fed, then the ECB, then the BOJ. "They're all printing," he said. "The question is who stops first." That day they shorted the Japanese yen because they believed the BOJ would maintain ultra-loose policy while the Fed tightened. The yen dropped 3% that week — they made a fortune.
Where it works: In periods of major economic shifts — rate hiking cycles, currency crises, commodity booms. Where it fails: In stable, low-volatility environments where macro bets just add noise.
Tools of the trade
- Currency forwards and options
- Interest rate swaps and futures
- Commodity futures (oil, gold, wheat)
- ETF baskets representing entire indices
4. Relative Value
Relative value is the quant nerd's playground. The idea is to find two similar securities that are mispriced relative to each other, buy the cheap one and sell the expensive one, and wait for prices to converge.
The most famous example is convertible bond arbitrage: buy a convertible bond and short the underlying stock. The bond is essentially a bond plus a call option on the stock. By shorting the right amount of stock (delta hedging), the manager extracts the cheapness of the option embedded in the bond. It sounds complicated — and it is. But funds that do this well can generate steady 5-8% returns with very low correlation to the market.
Where it works: In normal markets where pricing anomalies exist. Where it fails: During liquidity crises when all correlations go to 1 — like in 2008 when convertible arbitrage lost 30% because everyone was forced to sell everything.
Common relative value pairs
- Bond vs. CDS (credit default swap)
- Two related stocks in same sector (e.g., Coke vs. Pepsi)
- ETF vs. underlying basket
- Different maturities of same bond issuer
5. Managed Futures / CTA
Managed futures (also called Commodity Trading Advisors or CTAs) trade futures contracts across all asset classes using systematic rules. They're the trend-followers of the hedge fund world. If gold breaks out, they buy. If it falls, they short.
I visited a CTA firm in Chicago that ran purely algorithmic strategies. The co-founder showed me their code: it was a 200-page document filled with moving averages, volatility filters, and position sizing rules. "We don't predict anything," he said. "We just follow the trend until it breaks." During the 2020 crash, many CTAs made 20-30% because they were short equities since February.
Where it works: In trending markets — strong bull or bear moves. Where it fails: In choppy, range-bound markets where they get whipsawed (think 2015-2016).
