morning.
If you actually bought the stock in the after hours, then you own it at that price.
If you placed an order to buy the stock, but the order wasn't executed ....then you don't own any stock.
It seems most likely that you bought the stock at $5 and that you've made money.
If all you did was place an order, then you don't own any stock and it's possible the order will be filled (or won't be filled) tomorrow.
