There’s a saying for people who trades in stocks... “it’s only a lost if you sale”. Unless someone is a day trader, it’s never wise to hold individual stocks as they fluctuate wildly and can cause panic. In this case, it caused a dump of the stocks. Mutual funds is safer for long term.
Secondary, because the stocks was a gift and Was sold for less than it’s original value, this would be considered a lost and it is a legal tax write off. Unless a ton of money was made elsewhere, the tax bill should be near 0 for this year.
