Hi smart traders 
I’m doing a project and have done extensive research on many instruments. Naturally I am ignorant and need your sound knowledge please.
Assume the S&P increases over the next decade what would be the best investment with the highest return involving little capital ($10,000 )
I thought about
Shorting VIX
Shorting GLD ( options )
Buying Reverse gold etf
buy cheap S&P index trackers
