    Rapport Therapeutics is down 12.1% with extreme volume, but the supplied headlines are analyst target changes that are generally supportive rather than negative. Those ratings do not explain the sharp selloff, so order flow is driving the move in the provided material.

    WHYA 12.1% decline and 33.2x relative volume are far larger than the modest, mixed-to-positive analyst target revisions reported.

RAPP opened at $29.91, briefly set its session high there, then fell to a low of $24.69 by 10:31 ET as regular-hours volume reached 2.0M shares. It finished at $25.01, down 14.8% from the previous close, with no trading halts. TapeRank found the move unexplained: the available news consisted of generally supportive analyst actions, including Wells Fargo maintaining Overweight despite lowering its target to $50 and Guggenheim raising its target to $70, which did not explain the sharp selloff.
