Time for another original episode of "Ask Alan" with Alan Ellman of The Blue Collar Investor.

A regular subscriber asks the following:

"Alan, I am evaluating the recent member reports for covered call writing. Since it is earnings season, I turned to the ETF Report. I noticed one-month returns for iShares S&P Global Clean Energy Index Fund (ICLN), Invesco WilderHill Clean Energy ETF (PBW), Global X Lithium & Battery Tech ETF (LIT), and AdvisorShares Pure Cannabis ETF (YOLO) ranged from 6.4% to 9.1%. This doesn’t make sense that the ROO is so high. What am I missing and are these safe to use?"
