Dont take my word as fact, as its only an opinion.
But my understanding of taxes and stock market is that typically you would deduct your gains from your first shares you bought. So in this case you are only paying the capital gains earlier and not out any money.
Now on the other side, i dont see any reason why you cant claim you sold the shares you bout for a loss of 0.01 cents on it for this year and when you sell the rest you will have to sell at the original purchase price. When i do my taxes i have to enter all transactions i've done, or basically all sells i've done and the matched buy info. there is no reason i cant select the one i bought yesterday vs the one i bought a year ago. in the end it will even itself out and you shouldnt be out any money.
Thast my understanding of it anyway.
