indicated otherwise. Should you have run out and sold you Cisco shares? Maybe. But remember that ratios are just one angle of valuing stocks, and they should always be considered in relation to other factors such as how a stock's valuations fare versus others in the same industry.

Again the PEG ratio cannot be applied to all stocks broadly but perhaps to those with high earnings growth potential in rapidly expanding industries such as the high-tech during the 90s. And once again, since this ratio is based on past performance there are no future guarantees. And in Cisco's case such statement became painfully true for the many investors who lost money with this stock. Obviously companies with zero or negative earnings do not have meaningful PEG ratios. Investors must rely on other factors (such as estimate, sentiments, and luck) to value their stocks.
