With earnings season coming to an end, there's bound to be a few reporting companies that'll blow away analyst expectations. But how do you identify the companies that might report significant earnings surprises?

One way is to look at what insider executives are doing -- if they are using their own money to buy the shares of their employers, it may signal that they think earnings estimates are too pessimistic.

To compile this list, we started with a universe of about 200 companies reporting earnings next week.

We then collected data on insider transactions, and identified the companies that have had the largest increases in insider ownership over the last six months.

These insiders seem to think their companies are being underestimated -- will upcoming earnings result reflect insider optimism?
