"My experience with novice traders is that they trade three to five times too big. They are taking 5 to 10 percent risks on a trade when they should be taking 1 to 2 percent risks."
"Michael Marcus taught me one thing that was incredibly important... He taught me that you could make a million dollars. He showed me that if you applied yourself, great things could happen."
"Place your stops at a point that, if reached, will reasonably indicate that the trade is wrong, not at a point determined primarily by the maximum dollar amount you are willing to lose."
"Fundamentalists who say they are not going to pay any attention to the charts are like a doctor who says he's not going to take a patient's temperature."
Biography
Bruce Kovner is one of the most private and successful traders in financial history. He started with a **$3,000 cash advance on his credit card** in 1977 to buy soybean futures — and turned that into $40,000 before experiencing his first painful loss (his account dropped from $40,000 to $23,000 because he didn't use proper stops). That lesson shaped his entire career. He went on to found **Caxton Associates** in 1983, which became one of the world's premier macro hedge funds, managing over **$14 billion at its peak**. Over 28 years, Kovner averaged approximately **28% annual returns** with remarkably controlled drawdowns. He reportedly earned over **$300 million personally in his best years**. Despite his enormous success, Kovner remains intensely private — he reportedly owns one of the most expensive apartments in New York, has an unlisted phone number, and rarely gives interviews. He retired from active fund management in 2011.

Real Trade Example
The 1978 Soybean Trade — From $3,000 to Legend
Kovner noticed a potential supply squeeze in soybeans due to adverse weather affecting the Brazilian crop. His fundamental analysis suggested prices could rise significantly if the crop damage proved worse than expected.
Initial entry on $3,000 credit card — fundamental thesis: Brazilian supply squeeze
Weather reports confirmed crop damage — thesis strengthening, added 2nd layer
USDA crop report below expectations — full conviction, 3rd layer
Late trend addition — smaller to protect gains
Initial stop at $5.95 (below the consolidation zone). Moved up to $6.30 after 2nd layer, then to $6.65 after 3rd layer.
Soybeans surged to $7.80. However, Kovner held too long on the way down and exited at $7.15 — still netting ~$40,000 from his $3,000 start. But the painful pullback from $7.80 to $7.15 taught him his most valuable lesson: always use stops and take profits systematically.
This trade launched Kovner's career, but more importantly, the pain of watching profits evaporate from $40,000 back toward $23,000 before he exited taught him the stop-loss discipline that defined the rest of his career. He never again held a position without a clearly defined stop.
