So if you bought before the split you get the shares whatever, but if you bought pre-split you don't "get" the split you auto purchase through reconciliation the difference... Interesting.
How TSLA’s 5-for-1 stock split can affect your account
Tesla Inc. (TSLA) recently announced a 5-for-1 stock split. The split takes effect on August 31 for each shareholder of record on Aug. 21. The stock split happens automatically in your account and you are not required to do anything. TD Ameritrade does not charge a fee for this type of a stock split.
If you own shares of TSLA before the market open on Aug. 31 you will own five shares for every one you hold, and the stock price will be reduced to one-fifth of its value at the start of trading on Aug. 31. For example, if you hold 100 shares of TSLA trading at $1,500 per share, after the split you will own 500 shares valued at $300 per share. Likewise, if you own 1 options call controlling 100 shares with a strike price of $1,500, after the split you would own 5 contracts and control 500 shares at a $300 strike price.
If you sell TSLA shares after the record date of Aug. 21 for TSLA but before Aug. 31, you will sell them at the pre-split price. You will not be entitled to the split shares. For example: If on the last business day of trading TSLA, Aug. 28 you sell 100 TSLA shares for a pre-split market price of $1,500 per share you will receive $150,000. You will not receive any split shares.
If you buy TSLA shares after the record dates but before Aug. 31, you will purchase shares at the pre-split price. Following the split, you will receive the additional shares resulting from the stock split. For example: If on Aug. 26 you buy 100 shares (and hold them through the open on Aug. 31) at $1,500 per share, you will pay $150,000. You will receive 400 additional shares after the stock split, and the price will be reduced to the post-split price.
So if you bought before the split you get the shares whatever, but if you bought pre-split you don't "get" the split you auto purchase through reconciliation the difference... Interesting.
