Are there new laws in 2014 that will encourage investors to sell winners now? [View all]

I know that end of the year investors usually sell losers for the tax benefits, but wait till January if they want to capture gains.

There is one stock that I have been following, was really doing nicely and all of a sudden it is losing today, with no news.

So I wonder whether there are new laws in 2014 that would favor this.
