What to buy while waiting for NVDA pullback?

I sold all my NVDA stock last week of February (due to written call options being executed at $785). Since I still strongly believe in NVDA long term, I plan to buy them back on the next pullback.. I just wont allow myself to sell low, buy high..

Since NVDA represented around 30% of my portfolio, I have quite a bunch of cash sidelined now.. What would you recommend to invest this in, given my plan to reinvest this amount in NVDA within the next year? $NVIDIA(NVDA.US)$
