What it means
Robertson started Tiger Management in 1980 with a small group of investors and built it into one of the largest hedge funds in the world. His style was to study companies in detail, meet management teams and hold a mix of positions that could profit whether markets rose or fell.
The core of his approach was long/short equity. The fund bought, or went long, shares of companies it considered excellent and sold short shares of companies it considered weak.
A short sale means borrowing shares and selling them in the hope of buying them back later at a lower price. This structure aims to reduce the risk of the overall market.
If shares fall across the board, losses on the long positions may be offset by gains on the short positions. The manager's skill in picking winners and losers, rather than the direction of the market, drives the return.
Robertson was also known for his emphasis on training. He hired bright young analysts, taught them his process and gave them responsibility early.
Many later launched their own funds with his support, and they became known as Tiger Cubs, with the next generation called Tiger Seeds. The story has a sobering chapter.
In the late 1990s, value-oriented investing fell out of favour as technology shares soared, and Tiger suffered large losses and withdrawals. Robertson chose to return outside money to investors in 2000, which showed a belief in staying true to his discipline even when it was unpopular.
For managers and business readers, the lesson is the power of fundamental research and the danger of crowded or unfashionable positions. Being right can take time, and a strategy that is correct in the long run can still be tested badly in the short run.
Risk limits and honest communication with investors are as important as stock selection.
In practice
Real-world examples.
Example
A hedge fund analyst researches a retail company with falling margins and a heavy debt load. Following the Tiger approach, she recommends a short position, while buying a stronger competitor to offset market risk. The combination limits her exposure to a general market fall.
Example
A family office invests with a long/short manager hoping for steadier returns than a pure stock fund. In a falling market the fund loses less than the index because its short positions make money. The family office accepts that gains in a strong market may lag a pure stock fund.
Example
A student studies the Tiger Cubs to see how a strong culture of research and mentoring can spread through an industry. She notes that many of the later funds followed similar methods of deep company analysis. The pattern shows how knowledge and discipline can be passed on.
Formula
Calculation
Net exposure = (Long positions - Short positions) / Capital
Gross exposure = (Long positions + Short positions) / Capital
Suppose a long/short fund has $100,000,000 of capital, $120,000,000 in long positions and $40,000,000 in short positions.
Net exposure = ($120,000,000 - $40,000,000) / $100,000,000 = $80,000,000 / $100,000,000 = 80%
Gross exposure = ($120,000,000 + $40,000,000) / $100,000,000 = $160,000,000 / $100,000,000 = 160%
The fund is 80% net long, so it still gains when the market rises, but its shorts cushion falls. Its gross exposure of 160% shows that it is using leverage. Gross exposure above 100% means the fund holds more positions than its capital alone would allow, which magnifies both gains and losses.Case study
Seen in the real world.
This is an illustrative story about a fictional fund. Lynx Capital, an invented hedge fund inspired by the long/short approach, held $200 million in long positions and $80 million in short positions on $150 million of capital. The founder had trained under a well-known manager.
During a long technology rally, its short positions in overpriced companies kept losing money, and clients withdrew funds. The founder, Rafael, believed his analysis was right but understood that investors might not wait.
He reduced the fund's exposure to avoid a forced sell-off and explained the reasoning to clients in detail. In this fictional story, the shorts later paid off, and Rafael concluded that being right early can feel the same as being wrong. He later added a risk committee to review exposure each month.
Watch out
Common mistakes.
- Thinking long/short funds are always safe. Short positions can lose without limit if prices rise sharply. This is why risk limits are essential.
- Assuming a hedge fund simply copies the market. The aim is to profit from stock selection, not only market direction. Some funds still hold net long positions.
- Treating past success as a guarantee. Even the best investors suffer periods of poor performance. Investors should look at long track records.
