As always, depends on your appetite for risk and your timeframe for using the money. Personally, I don't see much upside left in equities for next year or two, but I'm a perma-bear and have been wrong many times before :D Plus there's not a lot of easy places to stuff money at the moment, hence big investors sitting on piles of cash.
I have only been investing for 2 years I am currently 32. So I think most investors wouldn't mind me keeping my stocks but I saw my mother and father loose hundreds of thousands of dollars back in 09 and I am not about to bite that bullet.
My portfolio was down 33% in 2008. That loss was quickly reversed with the 8% on average returns over the last 10 years.
