I've slowly moved to mostly cash in my retirement

I've slowly moved to mostly cash in my retirement accounts over the last couple years. Today I moved some back to money markets. I will slowly reduce my cash over the next couple of years. Unfortunately, I can't be cydy with most of my retirement accounts, but I do have a roth ira with cydy. The chart is also playing an issue with cydy imo, with the current overall downtrend.
