One Basic Rule – Let the Winners Run, Cut the Losses Quickly.
Overbuying and overstudying the market confuses your thinking. Limit your input.
There can be a second chance to sell if you’ve got a break out stock, that has dropped in value.
Watch that there is no lengthy period of distribution, and that the Point and Figure Relative Strength (RS) chart for the stock and the sector is still bullish.
If the stock fell while the market itself fell it may well be the “move of the majority”, and act as “test” of the breakout, and could then springboard higher, with another opportunity to sell.
