1 The Story

The decade of losing, then winning

Martin 'Buzzy' Schwartz (born 1945) spent roughly a decade losing money as a fundamental analyst before reinventing himself as a disciplined technical trader and winning the U.S. Investing Championship in 1984. He told his story in Pit Bull.1

His lessons centre on the inner game: cut losses without ego, reduce size after a loss to protect capital and confidence, and treat trading as a discipline rather than a display of brilliance.1

2 The Big Idea

Discipline beats brilliance

Protect your capital and your confidence — especially after a loss.

Schwartz's turnaround proved that analysis wasn't his problem; ego and risk control were. He learned to take losses fast, cut his size after a losing streak to steady himself, and let discipline — not cleverness — carry the results.1

3 The Method

The inner game

Take losses fast

Cut a loser without arguing with the market. Being wrong is cheap; staying wrong is ruinous.

Reduce size after a loss

After a losing streak, trade smaller to protect both capital and confidence — then build back as you stabilise.

Trade the discipline, not the ego

Treat trading as a craft of repeatable habits, not a stage for being the smartest in the room.

Schwartz's rule: after a loss, cut your position size to protect capital and confidence, then rebuild as you recover.1

4 Try It Today

Test the idea for yourself

A no-risk exercise

Look back at any losing streak (yours or a hypothetical). Ask: would trading half-size during it have protected your capital — and your nerve — enough to recover faster? That instinct to shrink, not press, is Schwartz's hardest-won lesson.
