A few (technical) reasons to sell:

1. Largest daily price run-up.

• Sell if an extended stock has its biggest gain since the move started.

• Being "extended" means it’s far above the buy point from a solid base.

• This usually occurs very close to a (temporary) top.

1. Heaviest daily volume.

• Sell on the heaviest volume day if the stock is extended.

• The ultimate top often happens on the highest volume day.

• Heavy volume means lots of institutional money is getting out.

1. Exhaustion gap.

• Sell if an extended stock gaps up.

• If a stock suddenly jumps or gap ups dramatically, it might mean the run is almost over.

• This is called an "exhaustion gap," and it often signals the top of the stock's move.

1. Climax top.

• Sell if a stock’s advance gets super extended with the biggest weekly price gain.

• This is called a „climax top”.

• This shows the stock is moving too fast and might be close to its top.

1. Signs of distribution.

• Sell when there’s a high daily volume with no price movement.

• Sometimes, the stock moves a lot one week but doesn’t go higher, with lots of trading. This is called "railroad tracks" because the volume chart looks like two parallel lines.

• It’s a sign of distribution because institutions are starting to sell.

1. Stock splits.

• Sell if a stock runs up 25%, 50%, or even 100% after a stock split.

• Watch out if a stock’s price is greatly extended and they announce a stock split.

• Stocks tend to top around excessive stock splits.

1. Consecutive down days.

• Sell if a stock has more down days than up days consistently.

• You might see four or five down days, then two or three up days.

• This means more stock is being sold than bought.

1. Upper channel line.

• Sell if a stock goes through its upper channel line after a huge run-up.

• Channel lines are upward lines that connect the recent lows and highs.

• A move above their upper channel line often marks the top.

1. 200-day moving average.

• Sell stocks that are 70% to 100% or more above their 200-day moving average.

• This one is rarely used.

1. Selling on the way down.

• Sell on the way down from the top, IF you didn’t sell while the stock was going up.

• After the first drop, some stocks bounce back once but won't get back to the last high.

• If you didn’t sell early, you have to sell late.
