True. There should be a simpler mechanism. In case of stocks, there exists the balance sheet but there should be something simpler yet more informative. For instance, the regular watchlist we have (on Yahoo Finance) with a couple more datapoints from the balance sheet.

Note that I used the word "stock" in its system-theoretic meaning, i.e. an accumulating quantity whose level depends on inflow and outflow. Not in the financial equity sense.
