Stock Watcher


DEFINITION of 'Stock Watcher'

A computer program that continually monitors trading on the New York Stock Exchange (NYSE). The stock watcher program is set up to isolate unusual trading activity resulting from rumors, manipulations or other illegal practices. In other words, the stock watcher helps maintain above-board trading on the NYSE.

BREAKING DOWN 'Stock Watcher'

If the stock watcher finds something amiss, the NYSE takes the appropriate action. This could mean requesting further information from the parties involved or turning the case over to the Securities and Exchange Commission. With approximately 8,000 issues (not counting European Structured Products) from more than 55 countries listed on the NYSE, the stock watcher provides valuable oversight assistance.
