Sell PDBC commodity ETF to go in on SPY?

When the stock market started getting turbulent and inflation was jumping, someone advised me to take money out of $SPDR S&P 500 ETF (SPY.US)$ (before it dropped a lot) and into something less volatile, like a commodity ETF (like $PowerShares Actively Managed Exchange-Traded Commodity Fund Trust PowerShares Optimum Yield Diversified Commodity Strategy (PDBC.US)$ ).
However, PDBC is highly energy-focused, so now I feel like I'm just in a different volatile market involving OPEC, Russia, and renewable energy advances. If this was meant to be a place to keep my head down and avoid market volatility, it isn't feeling like it.
Does anyone have any thoughts on the merits of selling all the PDBC to have cash that I can just DCA into spy over the next 12 months vs. keeping it in PDBC and selling off small bits over that time?
Basically, my concern is that if a recession hits and both of those tank then I won't actually be buying in at any sort of low price, relative to my original buying power.
