Stock splits, explained
What StockSplitWatcher tracks and why it matters
Forward splits vs. reverse splits
A forward stock split increases the number of shares while lowering the price per share, and is usually a sign of strength. A reverse stock split does the opposite: it merges shares to raise the price, often to keep a struggling company listed on an exchange. Reverse splits frequently precede further declines, which is why watching for them early matters. Learn more in our guide to reverse vs. regular stock splits.
SEC filings tell the story first
Before a split happens, companies file documents with the SEC that contain stock-split language — proxy statements, 8-K reports, and prospectuses. StockSplitWatcher scans these filings and links every match to the source document so you can verify it yourself. See exactly how the detection works in our methodology.
