Hi Tom,
I also took a 10% Sell order in my stock portfolio.
In this case I sold some IBM shares for a small profit.
This stock was not really moving, so I decreased the position.
I remember when buying this stock I followed Buffett a bit, that won't happen again. It was not a screaming buy at the time, but closer to fair value.
Nice to see a better alignment of Portfolio Control and Portfolio Value.
Best Regards,K
