I don't see the sell off. Rates low and economy good enough to keep profits decent but won't overheat. Unemployment will continue to be just ok keeping the fed on hold. All of this is a recipe for a sweet spot. JMHO
Good luck in whatever you decide but for me, I have given up on trading and trying to buy back. I always seem to get back higher than when I sold and like Bosie said, SNTA may just keep going with very little pull back to buy in.
