I would long QQQ/XLF or IWM and short SPY to hedge for a short term play. I like to long the strong one and short the weak one if I really want to bet on a pull back in a strong up trend like this one.
hehe.. the down side is that the mean reversion might start to work -- SPY turns stronger and QQQ weaker and I can get double turned. so it's only for short term play with nimble feet
