GR Engineering is worth a closer look. 

It is in a strong financial position, has a history of good and stable margin, high returns on equity and capital.

The market has a history of mispricing this one. Times when there are too much optimism, times when selling for liquidating prices.

In pass couple of years, its net operating cash flow has been negative. Possibly due to legal and contractual issue with one of its former client.

This profile does not contain any additional commentary or research from me. 

Though DangInvestors unique approach and metrics, together with useful hints and tips in the interpretation of financial statements should prove useful in your analysis.
