This ratio is the opposite of FCF Yield and was added to the screener to solve an important flaw. When sorting companies based on FCF yield, companies with a small enterprise value and positive FCF will show up at the top of the list but as soon as the EV becomes negative, the stock will drop to the bottom of the list. Similarly, stocks with a negative FCF and a negative EV are likely to feature at the top of the list.
To prevent this behavior, we created the EV/FCF ratio. Stocks with a negative FCF get a blank score and by sorting stocks ascending, stocks where the EV becomes negative don't get sent to the bottom of the list.
We calculate the EV/FCF as follows:
Stocks with an FCF <= 0 automatically get a blank score
