A stock split occurs when a company increases its number of outstanding shares by issuing additional shares to existing shareholders at a predetermined ratio. For example, in a 2-for-1 split, every share owned becomes two shares, each at roughly half the previous price. Despite this increase in share count, the total value of your investment remains the same because the price per share adjusts accordingly.

Historically, companies use stock splits to keep share prices within a range that is appealing and accessible to retail investors. Extremely high share prices might deter smaller investors who are unable or unwilling to purchase expensive shares. By splitting the stock, companies lower the price per share without diluting ownership value, helping maintain liquidity in the stock market.

To illustrate, suppose you own 100 shares priced at $100 each, totaling a $10,000 investment. After a 2-for-1 stock split, your shares double to 200, but each share’s price drops to approximately $50. You haven’t gained or lost money — your total investment remains $10,000, only split across more shares.

Before Stock Split Split Ratio After Stock Split
100 shares @ $100 2-for-1 200 shares @ $50
Total investment — $10,000 (unchanged)

Recent examples of stock splits include Apple Inc.’s 4-for-1 split in 2020 and Tesla’s 3-for-1 split in 2022. These actions lowered their share prices, making the stock more accessible to individual investors without changing the company’s overall market capitalization.

All shareholders registered on the split’s effective date receive additional shares proportionate to their holdings. For instance, if you own 50 shares before a 3-for-1 split, you will have 150 shares afterward without any additional investment.

Companies typically perform stock splits for several reasons:

  • Improve affordability: Lower share prices attract a wider investor base.
  • Increase liquidity: More shares in circulation can facilitate easier trading.
  • Enhance market perception: Lower stock prices may appear more attractive psychologically, potentially boosting demand.

Common misconceptions about stock splits include the belief that they increase the intrinsic value of a company or that they provide dividends. In reality, splits are purely cosmetic and do not affect your ownership percentage or the company’s total market value. Additionally, stock splits are generally not taxable events because your total investment doesn’t increase or decrease.

Investors holding shares in a company planning a stock split usually do not need to take immediate action. However, paying attention to reverse stock splits — where companies consolidate shares to increase prices — is essential, especially if considering stocks with potential financial difficulties. Reverse splits can indicate a company attempting to avoid delisting from stock exchanges.

Overall, understanding stock splits can help investors maintain perspective on their holdings and avoid misconceptions about the impact of these corporate actions.
