Problems with Enterprise Value and better valuation techniques
From Wikipedia: Usage Because EV is a capital structure-neutral metric, it is useful when   comparing companies with diverse capital structures. Price/earnings   ratios, for example, will be significantly more volatile in companies   that are highly leveraged. Stock market investors use EV/EBITDA to compare returns between   equivalent companies on a risk-adjusted basis. They can then   superimpose their own choice of debt levels. In practice, equity   investors may have difficulty accurately assessing EV if they do not   have access to the market quotations of the company debt. It is not   sufficient to substitute the book value of the debt because a) the   market interest rates may have changed, and b) the market's perception   of the risk of the loan may have changed since the debt was issued.   Remember, the point of EV is to neutralize the different risks, and   costs of different capital structures. Buyers of controlling interests in a business use EV to compare   returns between businesses, as above. They also use the EV valuation   (or a debt free cash free valuation) to determine how much to pay for   the whole entity (not just the equity). They may want to change the   capital structure once in control. Technical considerations Data availability Unlike market capitalization, where both the market price and the   outstanding number of shares in issue are readily available and easy   to find, it is virtually impossible to calculate an EV without making   a number of adjustments to published data, including often subjective   estimations of value: In practice, EV calculations rely on reasonable estimates of the   market value of these components. For example, in many professional   valuations: Avoiding temporal mismatches When using valuation multiples such as EV/EBITDA and EV/EBIT, the   numerator should correspond to the denominator. The EV should,   therefore, correspond to the market value of the assets that were used   to generate the profits in question, excluding assets acquired (and   including assets disposed) during a different financial reporting   period. This requires restating EV for any mergers and acquisitions   (whether paid in cash or equity), significant capital investments or   significant changes in working capital occurring after or during the   reporting period being examined. Ideally, multiples should be   calculated using the market value of the weighted average capital   employed of the company during the comparable financial period. When calculating multiples over different time periods (e.g. historic   multiples vs forward multiples), EV should be adjusted to reflect the   weighted average invested capital of the company in each period. In your question, you stated: The Market Cap is driven by the share price and the share price is   determined by buyers and sellers who have access to data on cash and   debts and factor that into their decision to buy or sell. Note the first point under "Technical Considerations" there and you will see that the "access to data on cash and debts" isn't quite accurate here so that is worth noting. As for alternatives, there are many other price ratios one could use such as price/earnings, price/book value, price/sales and others depending on how one wants to model the company. The better question is what kind of investing strategy is one wanting to use where there are probably hundreds of strategies at least. Let's take Apple as an example. Back on April 23, 2014 they announced earnings through March 29, 2014 which is nearly a month old when it was announced. Now a month later, one would have to estimate what changes would be made to things there. Thus, getting accurate real-time values isn't realistic. Discounted Cash Flow is another approach one can take of valuing a company in terms of its future earnings computed back to a present day lump sum.
