There are just 35 companies in the Nifty500 that fulfill the screener criteria of sharply rising net cash flow, operating cash flow, and low debt to equity. These include Solar Industries, FMCG company Britannia Industries and pharma company Sanofi India. 

Why is this important? Net cash flow is a useful indicator of a company's health, showing whether it has enough in the bank after fulfilling its debt obligations. This screener also looks at operating cash flows - money coming in from the company's business operations. This cash flow excludes money from borrowings, and so helps to reflect the real health of the company. 

In addition, looking at debt to equity helps check whether the company's debt is within manageable limits. For the full screener, click here.
