We show that the value of the Peskin-Takeuchi S parameter satisfies S>>0.2 in
a class of holographic technicolor models with weakly coupled vector and scalar
fields in the bulk. Our bound is in conflict with the results of electroweak
precision measurements which therefore strongly disfavor the models we
consider.
