Considering a short term high performing index etf stocks

Hi Guys,I was looking at some etfs to do better than 9% over the short term. This is short term only - about 1-2 years. I was looking at qqq, it did 30% over the last year and with the coming tax cuts, it looks like we will have another great year. Also what do you think of using margin for qqq? Again this is only for the short term and I will be monitoring my account and the market daily to be aware of any downturns.
