That sell-off, however, seems to have been enough to make some of these companies attractive again. At least in the short term. Small caps and internet companies have underperformed considerably. Conversely, some of the year's performers have been high-yield dividend stocks like utilities. We decided to find some plays that could benefit if the trend continues into the next couple weeks of earnings season. One good way to screen for potential earnings surprises, particularly among smaller companies, is by looking for spikes in insider buying. Insider buying is when workers at the company buy shares or add to their position. At large companies, this often isn't the sign of anything particularly interesting. One employee rarely has access to information that's going to greatly affect the entire company at large. However, smaller companies are a lot more cohesive. When insiders act on information, it is generally seen as a possible indicator that people working at the company expect growth in the future. We screened all the stocks with earnings next week for companies experiencing a spike in insider buying. We were left with 5 stocks on our list. Click on the interactive chart to view data over time.
