When to sell a stock

Three exits decided in advance beat any amount of judgement applied while the position is open. Two of them will feel wrong at the time.

Exit one: the target you set before buying

Sell into strength at a price you nominated while you were calm. Here that price is the largest gain comparable setups on that stock actually reached inside three months, capped by what the projected ceiling leaves room for — not a round number and not a wish. Placing it as a resting limit order the moment you buy removes the decision entirely, and removing the decision is most of the benefit.

Exit two: the trend break, which will feel like panic

A position that stops behaving like the setup you bought is no longer that trade. The rule used here is that a call is cut when price loses its 50-day trend and stays below it, and every live call on the track record that ended this way ended for exactly that reason. It fires while the story still sounds fine, which is what makes it useful and unpleasant.

Exit three: time

If a setup usually resolves in five weeks and yours has done nothing in fifteen, the thesis has quietly failed even though nothing dramatic happened. Money asleep in a stalled position costs you every setup you could not fund — the reason this site ranks candidates by profit per day of capital tied up rather than by the size of the target.

Selling at a loss, and the "never below cost" trap

The most expensive rule in retail investing is "I will sell once I am back to even". Your purchase price is information about your past, not about the stock: nobody else in the market can see it, and it has no bearing on where price goes next. A floor at your cost turns every losing position into an indefinite hold, and indefinite holds are how a portfolio ends up as a museum of past mistakes.

If you want a floor, put it under the exit rather than under the whole trade: refuse to take profit below cost — that is just arithmetic — but let the trend break and the time limit close a position wherever price happens to be.

Selling when a stock is falling fast

Decide by level, not by feel. If price is through the exit you nominated, sell and reassess from the sidelines, where the analysis is much better. If it is not, the fall is inside what the setup expected and the correct action is nothing. The reason to write the level down beforehand is that this judgement is impossible to make honestly at the time.

Stocks at the top of their channel — where profit-taking belongs — are on breakout stocks.
