1 The Story

The dancer who traded by telegram

Nicolas Darvas (1920–1977) was a Hungarian-born ballroom dancer who toured the world performing — and taught himself to trade along the way, communicating with his broker by telegram from hotel rooms in distant cities.1

Cut off from the rumours and noise of Wall Street, he was forced to rely only on price and volume. He distilled what he learned into his 'box theory' and told the story in the 1960 bestseller How I Made $2,000,000 in the Stock Market.1

2 The Big Idea

Buy strength breaking to new highs — and let a stop do the thinking

Strong stocks rise in stair-step 'boxes'; trade the breakouts.

Darvas noticed that leading stocks don't climb smoothly — they jump, then consolidate in a range (a 'box'), then jump again. His method was to buy the breakout from a box to a new high on heavy volume, set a stop just below the box, and ride the stair-step up, raising the stop box by box.2

3 The Method

The box theory

Define the box

After a new high, if price fails to make a higher high for several sessions, the recent high and low frame a 'box' — a consolidation range.

Breakout entry

Buy only when price breaks above the box top on a surge of volume — a genuine new high. Volume is the tell.

Trail the stop

Place a stop just below the box. As price climbs into new boxes above, raise the stop under each — locking in gains while letting the trend run.

Strength buys strength

Darvas focused on leading stocks with rising earnings in strong industries, making new highs — not cheap, beaten-down names.

The Darvas box: buy breakouts to new highs, trail the stop box 1 box 2 box 3 break out of each box on volume → buy stop below the box, raised box by box
Price builds a box, breaks out to a new high on volume (buy), then forms a higher box and breaks out again — with the stop trailed up beneath each box.2

A note on the story: the famous '$2,000,000' figure is Darvas's own account, and his results are debated. Read him for the method — disciplined breakout entries and trailing stops — rather than the headline number.

4 Try It Today

Test the idea for yourself

A no-risk exercise

Find a strong stock making new highs, then a spot where it paused in a tight range — a box. Mark the box top and bottom, imagine buying a breakout above the top on rising volume, and place a mental stop just below the box. Then watch how a trailing stop under each new box would have managed the trade.
