The Nasdaq / S&P ratio appears to have made a clear 5 wave rally from about June 9th until July 13th, and has resulted in a sell-off over the last two sessions.
It is possible that this is signalling a large and powerful sell signal in technology, which has led the rally since March, 2020.
This can be traded a few different ways, using options, ETFs, or futures.
Short Nasdaq, and long S&P.
