Wish you could get the inside scoop on your favorite companies? One way to get an inside peek is by looking at insider stock buying trends.

Company insiders, such as members of the board and upper management, report when they buy shares of company stock. When insiders at a company are buying more shares than selling, analysts take notice because who knows the prospects of their company better than they do?

To illustrate this, we ran a screen on dividend stocks of the S&P 500, paying dividend yields above 1% and sustainable payout ratios below 50%. We then screened for those with significant net insider purchases over the last six months, indicating that insiders at these companies expect their employers to outperform.
