What is Monolithic Power Systems worth?
On an owner-earnings DCF, Monolithic Power Systems's most-likely value is about $562 versus a recent price near $1,386 (59% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$128) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
