No one knows a company better than those who run it. Though they're not always right, the people in charge generally have more insight into how their companies will behave in the future.

Sometimes, we look to see whether insiders are buying stocks. Other times, we check to see whether the companies are buying back their own shares. Both of these can be bullish signs for a company.

Right now, we want to tap into management's knowledge by looking at companies that raise their earnings guidance for the coming quarter or year. Over time, earnings growth follows sales growth, and when a company says it will have more profits, we expect the stock price to soon follow.

Tap into CAPS
We'll enlist the Motley Fool CAPS community-intelligence database to pinpoint promising stocks. The system asks professional and novice investors alike to rank the thousands of stocks in our CAPS universe, overweighting the opinions of the most successful and accurate among them. From that data, CAPS rates each company from one to five stars, with five stars being the best.

At present, we're harnessing the knowledge of more than 24,000 analysts to get the inside scoop on whether these companies are a flash in the pan, or potentials with true staying power. Here are the latest companies to raise their earnings guidance, including the CAPS community's opinion on each:

Raising their voices
Here's what some CAPS players are saying about these stocks:

  • gcbrewer says of Boston Beer, "Craft beer continues its march in yearly volume growth, and the Samuel Adams brands are helping drive this growth."

  • Last August, top-rated CAPS player jmacn22 presciently noted: "Ann Taylor began its turnaround plans about a year ago, and results so far have been impressive. Inventory is tighter and the merchandise is more fresh. Double-digit comps in the most quarter suggest that things are working just nicely, thank you very much."
