What Does Let Your Profits Run Mean?

"Let your profits run" is a trading and investing principle that encourages investors to maintain their position in a successful asset rather than selling too early. The idea is to allow winning investments to continue compounding gains rather than locking in small profits prematurely. This approach contrasts with the common psychological tendency to sell winning positions quickly—often due to fear of losing unrealized gains—while holding onto losing positions in hopes of a rebound.

The phrase is often associated with trend-following strategies in both short-term and long-term trading, where the investor seeks to ride the momentum of a rising asset until there are clear signs of a reversal. The concept is simple on the surface but can be difficult to implement in practice due to emotional and behavioral biases.

Origins and Context

The principle behind “let your profits run” has been popularized through decades of market wisdom and is frequently quoted in trading literature. Though the exact origin is uncertain, the phrase became prominent with the rise of technical trading and momentum-based strategies in the 20th century. Traders like Jesse Livermore and Richard Dennis endorsed the practice, noting that major profits often come from a few large trades rather than many small ones.

The concept is grounded in behavioral finance. Many investors feel psychological discomfort watching paper profits evaporate, which causes them to exit positions too soon. This leads to the classic scenario where investors “cut their winners and ride their losers”—a pattern that can reduce long-term performance.

Application in Investing and Trading

Letting profits run is more commonly applied in equity markets, futures, and other liquid markets where prices can trend strongly over time. Traders using technical analysis may rely on indicators like moving averages, trend lines, or trailing stop losses to decide when to exit a position. The goal is to stay in the trade as long as the trend remains intact.

In long-term investing, the idea supports the notion of holding onto high-performing assets—such as stocks of companies with strong fundamentals—rather than selling simply because the price has appreciated. Growth investors, in particular, use this approach by staying invested in companies with long runways for expansion, even as prices climb.

However, the strategy isn't about never selling. It requires a disciplined framework for monitoring the investment and a clear set of criteria for identifying when a trend has potentially run its course.

Challenges and Limitations

While the strategy sounds appealing, it can be difficult to follow consistently. Several challenges often arise:

• Emotional Discipline: Watching a large gain shrink due to a price pullback can create anxiety. Investors may exit positions at the first sign of volatility rather than allowing the investment time to recover.
• Lack of Exit Strategy: Without predefined rules for when to sell, investors may either sell too early or hold too long and give back a substantial portion of their gains.
• Market Volatility: In volatile markets, sharp movements can trigger emotional reactions. An investor trying to let profits run may instead end up whipsawed—exiting and reentering at poor times.
• Tax Considerations: In taxable accounts, letting profits run can lead to larger gains and, potentially, higher tax liabilities. For some investors, the tax implications may weigh into the timing of an exit.

To navigate these challenges, many investors use trailing stop orders or a set of technical signals to protect gains while still allowing room for the investment to move upward.

Contrasts with Related Concepts

"Let your profits run" is often contrasted with “cut your losses short,” another foundational trading rule. Together, these ideas aim to promote risk management and capital efficiency: minimize downside and maximize upside.

However, some investors may misapply the phrase by holding on to winners indefinitely, even after fundamentals or technical conditions deteriorate. It’s important to distinguish between healthy momentum and overstretched valuations or signs of reversal.

Additionally, this principle is not always aligned with value investing philosophies. Value investors often set target prices based on intrinsic value estimates. Once a stock reaches that value, they may choose to exit regardless of market momentum.

Practical Examples

A real-world example might involve a long-term investor who buys shares of a growing tech company at $100. Within a year, the stock climbs to $160. Despite the temptation to take a 60% gain, the investor believes in the company’s continued growth and decides to hold. Over the next two years, the stock rises to $280, delivering significantly more value than an early exit would have allowed.

Conversely, a short-term trader may enter a position in a commodity ETF due to a breakout pattern. Instead of selling after a small move up, they use a trailing stop strategy, adjusting the stop loss as the asset rises. This method helps secure gains while remaining in the position as long as the trend continues.

The Bottom Line

"Let your profits run" is a time-tested principle that encourages investors to stay with successful positions long enough to realize their full potential. It’s a mindset that values patience, trend recognition, and discipline over emotional decision-making. Though it can be difficult to follow, particularly in volatile or uncertain markets, applying this principle with clear exit rules can improve long-term outcomes for both traders and investors. Success often depends not just on selecting the right investment but also on knowing how long to hold it.
