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.
