NEW YORK (TheStreet) -- Ebix (EBIX), Nanometrics (NANO), Synaptics (SYNA) and RF Micro Devices (RFMD) are a few technology companies generating significant free cash flow (operating cash flow deducting capital expenditure) along with an attractive free cash flow yield (free cash flow divided by enterprise value).Various quantitative valuation metrics such as the price-to-earnings ratio, price-to-book ratio and EV/EBITDA are used to estimate the worth of a company. However, apart from estimated earnings and stock price, the company's cash generation ability is of interest to a stockholder. Operating cash flow also indicates the operational efficiency of a company and updates its net cash inflow/outflow at the end of a period. Positive free cash flow signals excess money generation in the company in order to reinvest in the business. The company may also deploy this excess cash flow as dividend. Finally, free cash flow yield offers investors a better measure of a company's fundamental performance than the widely used P/E ratio.
