Does Tesla ring a bell? I day traded shares from $24 to $36 not long after they went public. Made some easy money. Cashed out completely the day before going on vacation only to see it pop to $68. I couldn't come close to repurchasing the number of shares I had played with originally... but I still bought enough to put a smile back on my face as I rode them past $300. But I still missed out on tens of thousands for not holding at least some shares before heading out on holiday. Vowed to hold a base ever since. All that said, in the case of FNMA, the actual 60% I'm currently holding is all gain from just over 5 years of trading this hopefull/hopeless stock.
