Without knowing anything about your particular situation or needs, I can only tell you what I would do (which may or may not be appropriate for you).
Unless you have some specific reason for believing it's going to move significantly higher or lower from here, I would wait a few days past 12 months from the purchase date (to get the long term capital gains tax rate), sell it, and split the proceeds between the SPY and QQQ ETFs, probably 75% SPY / 25% QQQ.
Don't forget to take out what you'll need to pay Federal and State income taxes.
Best of luck, whatever you decide to do
