It’s tempting but too risky for me. They can also run these baby bios up by several multiples very quickly, in which case you lose not only 100% of your investment but you actually owe them money. You also get the occasional early buyout, which crushes shorts. If you do it, better at least put in a stop loss and stick to it. It won’t help you if the stock gaps up huge one day but it’s better than nothing.
