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. Regardless of their motivation, we can better understand market sentiment by seeing who's watching what. 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 food and staples industry, watch interest is the percentage of people keeping an eye on food and staples stocks in general who are specifically watching each company. By looking at what stocks people are most interested in in an industry, you can get ahead of the curve by finding hot stocks that you might have otherwise overlooked.

Looking at the aggregate data, we see that Wal-Mart (NYSE: WMT) is above the rest in terms of watch interest and for good reason. As CAPS player tbonci wrote in May:

Looking toward future potential, Wal-Mart is seeking expansion into untapped developing markets. Even if the South Africa deal is a bumpy ride, the management clearly has their eyes set on moving to the large global stage, which will only be good for shareholders.

Here are the rest of the 15 most-watched companies in the industry with their watch interest along with the stocks' CAPS rating to show the sentiment of our investing community.
