Some companies trade so cheaply that their cash balance is worth more than the company's enterprise value (i.e. the sum of the market cap and total long term debts). This is known as a negative enterprise value (EV) and searching for such companies is a common bargain stock strategy. While, in theory, a negative EV may seem to be an easy arbitrage opportunity, whereby one could buy all of the debt and equity in a firm and use its cash balance to cover costs and keep the difference, there are a number of reasons to be cautious: Firstly, the enterprise value may not have captured all of the debt outstanding in the firm (e.g. the present value of lease commitments) and secondly the cash balance is from the balance sheet (rather than stated at the today's date used for the market cap). Given how quickly firms burn through cash, what you see on the balance sheet may not reflect what the firm has as of today as a cash balance so be careful! You can read more here. more »
