Totally agree with you on the lost opportunity costs.
Someone put $1000 when $AMRN was sky high back in Dec 2019, man we have been in this debacle for 2 years!!!, kept holding it to March 2020 when $AMRN stock plunged by 85% to $4 (boy it was still higher than today's price), but then decided to take the burn and convert everything to $TSLA, he would still end up with $1600 in TESLA stock, instead of $160 in Amarin stock.
That how much opportunity cost lost for some of us.
