- hey Oliver there was a red day the day before yesterday of minus 10%, did you miss that ?

No I didn't miss that.
But for me yesterday. Everything else that I actually hold and most things in my watchlist were green.
That was the difference for me.

So therefore,.. for me,.. I can rule out 'general market sentiment' explaining the sell off.
So I begin to look for company specific info.

So what are other reasons?
All I can think of are.
1. A lot of smaller holders stop losing.
2. A major fund or holder knows something the rest of us don't.
3. A major fund or holder needs a capital loss for tax time?

A combination of the above?

Please add any possible reasons.
