If you aren't already invested in energy, I wouldn't be jumping in with both feet now, no matter what this theory suggests. The charts look very extended, they ran too far too fast, they need a pause/consolidation, etc.

And if you like to trade, this may be the time to consider letting some go, selling covered calls, etc, depending on what you think the charts tell you. In particular, I would point out the candlestick charts appear to show reversal signals.
