13 times. good to know. oh, not to complicate things further, but if one starts with 10k shares, sells half of them, and subsequently buys back 1/2 of their "new" position, they would end up with only 7500 shares(less taxes, commissions and potential missed gains). perhaps in the future, posters would be kind enough to identify whether they are talking about their "original" positions or their "new" positions so the rest of us can more easily follow along ;)
