Waters Corporation stands at a valuation crossroads that mirrors a timeless tension in markets: the gap between what a company earns today and what investors believe it will become. Two honest methods of measuring worth arrive at contradictory verdicts — one pointing to a 21% discount, the other to a price nearly three times fair value — and the distance between them is filled entirely by faith in future execution. What the stock is worth, in the end, depends less on arithmetic than on whether a company can honor the promises its price has already made.
