I don’t think NVII is a covered call strategy…more so a leveraged ETF.
If you compare NVII and NVDA from end of May 2025 to August 2025, the trend is the same, strong up. But, because NVII is leveraged 105-150% of NVDA, when NVDA chops sideways, the ETF goes down. Say, NVDA goes up 10% one day, but then down 10% the next. The ETF will go up say 13% and then down 13%. Mathematically, you get 98.3% of your starting point. Vs NVDA gets you 99%. So, they both lose money vs your starting point but NVII loses more. That’s why you see NVII going down after that NVDA climb. So, yes, it’s supposed to be temporary and held in upward swings.
