We show that the pseudo Nambu-Goldstone boson contribution to the Peskin-Takeuchi electroweak parameter [ital S] can be negative in a class of technicolor theories. This negative contribution can be large enough to cancel the positive technihadron contribution, showing that electroweak precision tests alone cannot be used to rule out technicolor as the mechanism of electroweak symmetry breaking.
