There is a very simple reason for this, any covered call ETF will "always 100%" underperform the underline stock on which it writes covered call. If you were to buy a covered call ETF, you might as well buy the stock directly.
Take NVDY as example, it is a covered call ETF on NVDA. Yes, you might think its current yield of 63% looks unreal, but that is because NVDA has had a huge run up. If you plot NVDY and NVDA on the same chart, you will see
1: NVDY's overall return is signficantly lower than NVDA
2: Whenever NVDA drops, NVDY also drops, and therefore offers no real protection on the downside risk.
Net net, you are better off to buy NVDA directly if you want to buy NVDY. You can plot "any covered call ETF" against its stock and you will see this behavior 100% of time.
So, never touch any covered call ETF
