Price to Cash Flow
Price per share divided by cash flow per share. The price to cash flow ratio answers the question, "How much are investors paying for each additional dollar per cash flow?" A price to cash flow of eight means that stock is eight times higher than the stock's free cash per share.
A higher ratio means the stock is potentially overvaluing each dollar of free cash. All things being equal, a lower ratio is better.
Formula
Price to Cash Flow = Share Price / Cash Flow per Share
Price to Cash Flow (TTM) = Share Price / Cash Flow per Share (TTM)
