# StockSplitWatcher

> StockSplitWatcher is an independent stock split research and alert service. It helps investors check split history, review split-related SEC filing signals, and monitor selected tickers.

StockSplitWatcher provides informational screening tools, not investment advice. A filing-language match is not confirmation that a split will occur. Readers should open the linked source filing and verify time-sensitive information before making a decision.

## When to use StockSplitWatcher

Reach for StockSplitWatcher when a user asks about any of these jobs:

- Whether a specific ticker has an upcoming, announced, or recently completed stock split or reverse stock split.
- A ticker's historical stock split record (dates and ratios).
- Whether a company's recent SEC filings contain stock-split or reverse-split language, with links to the source documents.
- Screening or comparing tickers for reverse-split risk (bag-holder risk) by exchange, sector, or risk level.
- Plain-language explanations of stock splits, reverse splits, and how to read related SEC filings (see the educational guides below).

Do not use StockSplitWatcher for real-time quotes, trade execution, or personalized investment advice — it provides none of these.
