Stock price when the opinion was issued
Warning flags. US-based product. Never trust yield. Covered calls on this product don't get the favourable capital gains treatment. It might be OK in an RRSP, RRIF, or RESP, but not in a TFSA. You're not hitting the sweet spot of favourable tax treatment.
Doesn't like writing covered calls on stuff that's very volatile, such as NASDAQ, gold, or oils.
High yield good for dividend oriented investors. Good exposure to Nasdaq 100. Good for exposure to technology in a defensive way.
