Good lord, if you'd put $10 into that during the panic, you'd have $40000 now.

Someone has to actually sell you shares at that price for that to happen. It was likely a data error. No one is going to sell Accenture shares for a penny.

Or a bit more precisely: Someone might have entered a big sell order at $0.01/share by mistake, but when this happens the stock exchanges usually undo those trades, so even if you think you bought ACN for $0.01/share, you probably didn't.

It's very likely that trade got busted almost immediately.

When I worked at an HFT shop broken trades were the bain of our existence. We had parameters to screen for trades that would probably be broken, but sometimes they would be broken outside of those. The way it works is either party to a trade can request the trade be broken, it goes to a mediator, and both sides make there case. It usually only takes a few minutes, but you can lose a bundle in that time especially if you were selling as the price is dropping, think you're flat only to have your sale broken.

It is possible that somebody did, however, it would have been a data entry mistake.
