Recent examples of stock splits are tesla's, 5 to 1 stock split in 2020 and now amazon and google, with the announcement to split the shares 24 1.. This decision is often made when the stock price has increased substantially. As you can see from this amazon chart, amazon was one trading at 15 after the dot-com bubble more than 20 years ago, and it's the same scenario with google stock. All these share prices have gone up exponentially and are seemingly too expensive.

If we take a look at the apple share prices without the previous four stock splits, the stock will be trading at eighteen hundred dollars. Today, as for tesla, it will be around four thousand dollars. So by splitting these stocks, the stock prices appear to be cheaper. However, your total ownership, as an investor, would remain the same.
