This is not to say, however, that you cannot make profits by taking advantage of occasional under valuation of smokestack shares. Asset intensive businesses do, from time to time, sell at prices far below liquidation or replacement value, at which times they may make for bargain opportunities. In fact, when an asset intensive business is trading below the replacement value of its equipment and systems, management can best serve shareholders by repurchasing shares.
The most effective way to gauge the asset intensiveness of a business is to calculate the return on assets (ROA for short). The return on assets financial ratio tells an investor the return a business earned on all of the assets it has at its disposal, including borrowed money (note that if a company has no debt, the return on equity and return on assets will be the same). For instance, a company with a 15% ROA earned $0.15 for each $1 in assets.
