Frequently Asked Questions
A stock split is when a company divides its existing shares into multiple new shares. For example, in a 4-for-1 split, each share becomes 4 shares at one-quarter the original price. The total value of your holdings stays exactly the same — only the number of shares and price per share change.
Companies typically split their stock to make shares more accessible to individual investors by lowering the per-share price. A stock trading at $1,000 may seem expensive, but after a 10-for-1 split it trades at $100. Splits can also increase liquidity and trading volume. Splits do not change the company's market capitalization or fundamental value.
No. A stock split does not change the total value of your investment. If you owned 10 shares at $200 ($2,000 total) and the company does a 2-for-1 split, you now own 20 shares at $100 each — still $2,000 total. The split is purely cosmetic in terms of value.
A reverse stock split consolidates multiple shares into fewer shares at a higher price. In a 1-for-2 reverse split, every 2 shares become 1 share at double the price. Companies sometimes use reverse splits to meet stock exchange minimum price requirements or to reduce the number of outstanding shares. Like forward splits, reverse splits do not change total investment value.
Apple has split five times: 4-for-1 in 2020, 7-for-1 in 2014, and three 2-for-1 splits earlier. Tesla did a 5-for-1 split in 2020 and a 3-for-1 split in 2022. Amazon did a 20-for-1 split in 2022. Alphabet (Google) also did a 20-for-1 split in 2022. These splits made shares more affordable for individual investors while not changing the companies' total market value.
