Not much meaning in this chart.... mostly because you wouldn't be holding in a leveraged vehicle during a bear market. The chart below justifies trying to do something with the TQQQ instead of the QQQ... if you can handle the volatility.
%% That's a way to make money with it. .In other words , the large prospectus is right=its not buy + hold\ like you could profit easier that way with spy +QQQ. Another way to profit with it\if you thought SEPT was gong to be down+ OCT tends to be a bear killer[bullish /uptrend]; you could most likely figure out a trade with it. NOT a prediction, not suitable for all investors/
