Yeah the way this is playing out is pretty interesting. I would recommend loading up on SDP (UltraShort Dow Utilities Sector ETF) or selling puts whenever this bounces.
To be honest I don't like how overweight NEE is in XLU, so maybe RYU (Equal Weight S&P Utilities Sector ETF) is more representantive of this idea that the best performing sector of Q4 is now being rotated out of.
