Now that earnings season is underway, many companies will be releasing their second quarter results over the coming weeks, writes Mary-Lynn Cesar on Kapitall.com.

For the following screen, we set out to find out promising investment opportunities amongst those that will report their earnings the week of July 15-19. If you're looking to trade on earnings season, you may find our list of stocks quite appealing.

Investing Ideas
To begin, we screened the aforementioned group of companies for firms that have a strong history of posting earnings that beat expectations, commonly referred to as a positive earnings surprise. Specifically, we looked for companies that have reported earnings per share (EPS) above the expected EPS for the last four consecutive quarters. It's also worth mentioning that the difference between the actual and expected EPS doesn't have to be huge for it to count; a difference of a few cents is still a positive earnings surprise. And while past performance isn't indicative of future returns, four or more quarters of positive earnings surprises may suggest that a company is being consistently undervalued by investors.

Next, we decided to narrow down that list by taking a closer look at the profitability of the remaining companies. To do this, we used the DuPont equation to analyze the firms' return on equity (ROE). ROE is essentially a company’s net profits divided by its average equity. Typically, the higher the ROE, the more profitable the company.

DuPont stretches the ROE equation into 3 parts:
= (Net Profit/Equity)
= (Net profit/Sales)*(Sales/Assets)*(Assets/Equity)
= (Net Profit margin)*(Asset turnover)*(Leverage ratio)

This enables us to examine the strength of a company’s major sources of profitability. Generally, an increase in net profits or asset efficiency is viewed as a positive source of growth, while an increase in leverage ratio (debt) is viewed as a negative. So for our purposes, we screened for companies with an increasing net profit margin and asset turnover, and a decreasing leverage ratio. Companies satisfying that requirement are experiencing rising profits due to operations and not increased use of leverage.
