How I Made $2,000,000 in the Stock Market

Author: Nicolas Darvas

One-line description:

A dancer’s journey from speculative trading to a disciplined investment method built around price, volume, growth and controlled losses.

1. What the book is about

The book describes how Nicolas Darvas, a professional dancer and self-taught investor, developed his famous Darvas Box Theory through repeated successes, mistakes and careful observation.His progress came from changing his behaviour as much as changing his stock-selection method. He gradually abandoned tips, predictions and emotional trading, replacing them with clear entry rules, stop-loss orders and patience.

2. A lucky beginning—and the dangers of overconfidence

Darvas’s journey began with a profitable investment in the Canadian mining company BRILUND. He bought 6,000 shares at $0.50 and later sold them at $1.90.

This early success persuaded him that making money in stocks was easy. He began following acquaintances’ recommendations, advisory newsletters and speculative tips. The resulting losses exposed the weakness of his approach: he was gambling without a consistent method.

Key lesson: A profitable trade does not necessarily prove that the decision behind it was sound.

3. Wall Street and the limits of professional advice

After his Canadian losses, Darvas turned to the New York market. He believed that established companies, professional advice and financial analysis would improve his results.

His initial capital grew, but frequent trading generated commissions, and selling successful positions too early limited his gains. He also began recognising that a rising market had contributed to his success.

He studied earnings, dividends, balance sheets and company ratings, yet these did not fully explain why some stocks advanced while others declined.

Key lesson: Independent judgment, patience and selective trading matter more than constant activity.

4. From fundamentals to price behaviour

Two contrasting trades changed his thinking:

• He bought Jones & Laughlin Steel because of its attractive valuation, dividend and industry        position. However, the share price continued to decline despite its strong fundamentals, forcing    him to exit at a substantial loss.
• He bought Texas Gulf Producing because its share price was steadily rising. The trade earned him a significant profit, strengthening his belief in the importance of price behaviour when selecting stocks.

Darvas increasingly treated price behaviour as evidence. Rather than insisting that the market recognise his assessment of a company, he began looking for stocks already demonstrating strength.

Key lesson: A promising company still needs a suitable entry point and confirmation from the market.

5. The development of Darvas Box Theory

Darvas observed that stocks often moved within identifiable trading ranges, which he called boxes.

A stock forming successively higher boxes suggested an upward trend. A breakout above a box could provide an entry opportunity, while a breakdown indicated weakness.

His developing method combined:

• Price strength: Look for stocks moving upward through higher trading ranges.
• Volume: Notice unusual trading activity that may signal growing interest.
• Planned entries: Place buy orders at predetermined breakout levels.
• Controlled losses: Use stop-loss orders and accept failed trades promptly.
• Patient exits: Allow successful positions to continue while their behaviour remains favourable.

His M & M Wood Working trade reinforced his belief that unusual price and volume activity could appear before the underlying news became widely known.

Key lesson: Profits must cover losing trades and trading costs; avoiding every loss is unnecessary.

6. Trading around the world: distance improved discipline

During an international dancing tour, Darvas traded through telegrams. Surprisingly, being far from Wall Street improved his decision-making.

He followed a simple routine: using weekly Barron’s to identify potential stocks, daily price telegrams to monitor closing prices and trading ranges, predetermined buy and stop-loss orders to manage trades, and a trading journal to record recurring mistakes. He recorded errors such as late entries, overly tight stops and buying during unfavourable market conditions.

Key lesson: Relevant information and a consistent routine can be more useful than constant market commentary.

7. The techno-fundamentalist approach

A market decline helped Darvas refine his method further. He stayed in cash when opportunities were weak and watched for stocks showing unusual resilience.

He noticed that some strong stocks also had improving earnings prospects. This led to his techno-fundamentalist approach:

Identify strength through price and volume, then examine whether business growth supports it.

He preferred companies with substantial future potential and became comfortable buying near new highs when both market behaviour and growth prospects supported the trade.

He also looked for emerging leaders rather than assuming that the previous bull market’s winners would lead again.

Key lesson: Combine technical confirmation with business potential, and recognise when remaining in cash is appropriate.

8. Major winning trades

Several trades demonstrated how his developing method worked.

1. Lorillard  showing rising price and heavy volume attract him despite a weak market. His first purchase was hit with stop-loss, but renewed strength prompts him to re-enter and eventually earns $21,052.95.
2. Diners’ Club validates his theory as it has strong earnings and rising boxes support his purchase. When price behaviour weakens, his trailing stop sells the position for a $10,328.05 profit—before news emerges of competition from American Express.
3. E. L. Bruce showing exceptional price and volume persuade him to make an exception to his usual fundamental requirements. He builds a position as it rises. A takeover struggle and short squeeze drive extraordinary gains of $295,305.45.His later portfolio also included Texas Instruments, Zenith Radio and Fairchild Camera.

Key lesson: A relatively small number of large winners can make a substantial contribution when losses remain controlled.

9. Success, overconfidence and a costly setback

After substantial gains, Darvas returned to New York and became absorbed in brokerage-office discussions, ticker watching and market gossip.

He departed from his established rules, traded impulsively and repeatedly bought high before selling in panic. Within a few weeks, his losses approached $100,000.

He recognised that his behaviour had changed. To restore discipline, he left for Paris, restricted unsolicited broker contact and returned to his quieter system of daily telegrams and planned decisions.

Later, he maintained the same distance from market noise even while living in New York.

Key lesson: A working method loses its value when overconfidence causes the trader to stop following it. 10. The ending and supporting material

The final portion recounts the scrutiny surrounding his Time magazine interview and the publicity that helped lead to the book.

The supporting material includes trading cables and charts illustrating his decisions. The ending also includes unrealised portfolio gains, so the final figure should not be understood as money entirely withdrawn into cash.

The book’s central message

Darvas’s achievement came from a repeatable process:

Select strong stocks, wait for a suitable entry, control losses, add when strength confirms the decision, and allow winners time to grow.

The deeper lesson is emotional independence. His results improved when he followed observable market behaviour and clear rules—and deteriorated when excitement, opinions and overconfidence displaced them.
