In September 2000 Intel trimmed one quarter's revenue guidance by a few percentage points and lost nearly 30% of its market value in five days. Either the market had just repriced a permanent change in fundamentals, or the announcement was a catalyst that pushed an already overvalued stock toward intrinsic value. Deciding which is the whole job.
Valuation is the estimation of an asset's value from variables believed to drive future investment returns, from comparison with similar assets, or from estimated immediate liquidation proceeds. Intrinsic value is the value of an asset given a hypothetically complete understanding of its investment characteristics. Active investing only makes sense if market price can differ from intrinsic value .
The Grossman, Stiglitz paradox explains why. If freely available prices already reflected intrinsic value perfectly, no rational investor would pay to research securities; but if nobody researches, prices cannot reflect value. The rational efficient markets formulation resolves this: investors research only because they expect gross returns above the free alternative of accepting the market price.
Common mistakes
- Treating the whole $12 gap as alpha. Estimated value minus price mixes true mispricing with your own error; only can pay.
- Applying liquidation value to a healthy firm. Going-concern value normally exceeds liquidation value; liquidation is the benchmark for distress, and forced sale differs from orderly sale.
- Using fair market value or investment value for a public stock. Intrinsic value under a going-concern assumption governs; investment value includes buyer-specific synergies that a minority shareholder never receives.
Bottom line
- Valuation estimates value from return-related variables, comparables, or liquidation proceeds; intrinsic value assumes complete understanding of the asset
- Mispricing decomposition: estimated value minus price equals true mispricing plus estimation error; only true mispricing earns alpha
- Grossman, Stiglitz: prices cannot be perfectly efficient if research is costly, which is what makes active management coherent
- Going concern assumes continued operations and usually exceeds liquidation value; orderly liquidation beats forced liquidation
Exam shortcut
If a stem gives you an estimate, a price, and a later "true" value, it is testing the decomposition. Subtract in this order: intrinsic minus price is the payable piece; estimate minus intrinsic is the error. The trap answer credits the full estimate-minus-price gap as alpha. Stem signals map to definitions. "Willing buyer, willing seller, neither compelled" is fair market value. "Synergies to this acquirer" is investment value.
