前幾天特斯拉一天突然大漲20%， 正好需要用錢，就賣了一些 @258-256，今天看價格低於我賣的，就買了一些@249.6-250， 突然發現下麵的信息。然後購買價格調到了264. 然後旁邊是下麵的消息：The cost basis is adjusted by a disallowed loss from a wash sale. Select the position to view Purchase History for more details.
我問了一下chatGPT, 是這麽解釋的： When you sell an investment at a loss and then quickly buy it back, the IRS considers this a "wash sale." This rule stops you from using that loss to lower your taxes right away. Instead, the amount of that disallowed loss is added to the cost of the investment you just bought. This adjusted amount will be your new starting point (or "cost basis") for figuring out any future gains or losses. To see more details on what you paid and how your cost basis was adjusted, you can look at the "Purchase History" of that investment.
這是不是我操作油違規之處， 我這通操作看起來好像是掙錢，實際是賠錢對嗎 （賣在259， 買在264）？ 是不是以後要避免這麽操作。多謝。
