Ticker&TapeTaking profits: when to sell a winner
Buying is half the job. Many traders cut losses well but then give back their gains because they never had a plan for selling. These guidelines help you lock in profits without selling true leaders too early.
Take most gains at 20% to 25%
A simple base rule: when a stock is up 20% to 25% from a proper buy point, consider selling most or all of it. Many breakouts advance this much and then build a new base, often pulling back enough to erase a big part of the gain.
Combined with a 7% to 8% maximum loss, this creates roughly a 3-to-1 profit/loss ratio. You can be right only a third or 40% of the time and still make money if your average gain is about three times your average loss.
The 8-week hold rule
There is an important exception. If a stock jumps 20% or more within three weeks or less of breaking out, it may be a true leader. Hold it for at least eight weeks from the breakout (unless it hits your stop), instead of taking the quick 20%.
Those explosive starts are the ones that sometimes become 100% or bigger winners. The rule protects you from selling them out of habit.
Sell into strength
The easiest time to sell is when buyers are eager: on an up day, while the stock is rising. Waiting for the first sharp drop means selling into weakness, often at a worse price. Signs that a big run may be ending include:
- The biggest daily gain or the widest weekly range of the whole move, after a long advance.
- A burst of several up days in a row on high volume, far above the moving averages (a climax run).
- An exhaustion gap late in the move.
- A late-stage base, the third or fourth since the start of the trend (see base count).
Sell on breaks of key moving averages
For stocks you decide to hold, the moving averages act as trailing guides. A decisive close below the 50-day line on heavy volume, especially if the stock can't recover it in the next days, is a classic sell signal. Longer-term holders often use the 10-week line on the weekly chart instead: a weekly close well below it on rising volume is the signal to get out.
Selling in pieces is fine. You might sell half at 20% to 25% and hold the rest with a stop at the 50-day line. That way you lock in a profit and keep some exposure in case the stock becomes a big winner.
Profit-taking guidelines
| Normal target | Sell most at 20% to 25% above the buy point |
|---|---|
| 8-week hold rule | Up 20%+ within 3 weeks of breakout: hold at least 8 weeks |
| Climax signs | Biggest gain of the move, gaps, many straight up days |
| Trailing exit | Heavy-volume close below the 50-day (or 10-week) line |
| Profit/loss goal | Average gain about 3 times average loss |
Common mistakes
- Letting a 20% gain turn into a loss because there was no sell plan.
- Selling a stock that rocketed 20% in two weeks, instead of applying the 8-week rule.
- Waiting to sell until after the first big drop instead of selling into strength.
- Holding late-stage bases with the same confidence as first-stage ones.
Key points
- Take most gains at 20% to 25%, unless the stock gains 20% in three weeks or less; then hold eight weeks.
- Sell into strength and watch for climax signs after long advances.
- Use the 50-day or 10-week line as a trailing exit for the shares you keep.
Check what you learned
Answer at least 2 of 3 correctly to complete the lesson.
1. A stock gains 22% in its first two weeks after breaking out. What does the 8-week rule suggest?
A 20% gain in three weeks or less can mark a true leader. Holding protects you from selling a potential big winner out of habit.
2. Why does taking most gains at 20% to 25% work alongside a 7% to 8% maximum loss?
When the average gain is about three times the average loss, you do not need to be right most of the time.
3. Which of these is a sign that a long advance may be ending?
After a long run, the biggest gains, widest ranges or an exhaustion gap often come near the top. Selling into that strength is easier than selling into weakness.
