Stock splits
A stock split changes the number of shares and the price of each one, and that's it. Ten for one turns a single $500 share into ten $50 shares. Same company, same slice of it in your hands, same total value. Nothing about the business is different the morning after.
So the interesting question isn't what a split does, it's who does them and why. And the answer surprises most people. There were 410 splits in 2025 and only 62 were the kind you're picturing, a successful company dividing its shares. The other 348 were reverse splits, where a company merges shares together to lift a price that has fallen too low, and that was a record. This page has the counts for 2024, 2025 and the first half of 2026, the reason reverse splits outnumber forward ones roughly five to one, what the research says about the announcement effect, and the single index where a split genuinely changes something.
I wrote this one because splits get more commentary than almost any corporate action and most of that commentary is describing an event that didn't happen. The counts come from one provider, with a second source for the trading volume figure, both linked at the bottom with their dates. One provider is a real limitation, so treat the exact numbers as one careful count rather than the count.
There were 410 stock splits in 2025, of which only 62 were forward splits and 348 were reverse splits, a record. Through 8 June 2026 there had been 37 forward and 111 reverse splits. Forward splits are what people picture, a successful company dividing its shares, and they are the small minority. Reverse splits, which consolidate shares to lift a low price, are roughly five times more common and describe a very different set of companies.
