Funds just sell mainly for one of three reason:

a) The Stock target price is achieved (bottom or upside);

b) The Stock no longer fits with the newly adopted strategy;

c) The Funds needs liquidity, and the Stock is the closer to (b) above ;

Not retail thinking there. No emotion. Triggering the sell button, that's it.

So nothing to worry. If there was a rumour or something, the stock would fall like a rock on heavy volume. So, again, just sit back, and relax. You don't stare at your plant for hours after watering it.

Or you may also trigger the sell button, and use the proceed for another play. Like the fund just did. GLTA. BB.
