People watch stocks for different reasons -- they're waiting for a dip in price, watching for a specific catalyst, gathering all the news and information that might affect stocks they already own, or considering a sell.

With the Fool's free My Watchlist service, we have tens of thousands of people telling us the businesses that have, for whatever reason, piqued their interest.

With this data we have come up with a new metric, watch interest, to inform investors what stocks their peers keep tabs on in each industry. In the case of the communications-equipment industry, watch interest is the percentage of people keeping an eye on communications-equipment stocks in general who are specifically watching each company.

Here are the rest of the top 10 most-watched companies in the industry, with their watch interest and the stocks' CAPS rating to show the sentiment of our investing community.
