Ideas: 10 Stocks With Rising Gross Profit Margins and Insider Buying

Looking for stocks that have strong profitability and the support of company insiders? Here are some ideas to get you started.

Profitability margins such as gross margin are helpful to gauge how much profits a company is taking from its revenues. Specifically, gross margin is the profit after deducting "cost of goods sold," which includes inventory. Therefore companies with higher gross margins are more profitable and have a greater control of their costs.

For companies that sell physical inventory, gross margin is a very important measure because cost of goods sold is usually the largest expense on the income statement.

Investment ideas
We ran a screen for stocks with high profitability by searching for those that are seeing consistent increases in gross margin over the last four years, indicating that the stocks are keeping a greater portion of revenue as profits.

We then screened these stocks for those with significant net insider buying over the last six months, which indicates that company insiders such as upper management believe in the company's outlook.

Do you think these insiders are calling it right on their companies?
