Soitec is giving you a lesson.

So many have already taken profits or sold their positions. Why? Because the stock ran too much, too fast. They are probably regretting it today.

What a terrible reason to sell a stock...

You do not buy a number; you buy a thesis or a plan. You have to stick to it as long as nothing changes or as long as your targets haven't been met.

This is the hardest part of investing: holding onto your winners. The only way to do so is to have a clear system and the strength to stick to it.

Never sell your winners too early.
