NEW YORK — One of Tuesday's standout movers sets up the next session's watch list. Myriad Genetics jumped roughly a third in midday trading after announcing it will sell its prenatal health testing business to Labcorp, a divestiture that resets the story for a diagnostics stock whose second-quarter revenue had fallen 11 per cent year over year on lower prenatal volumes and payer friction.

The move came with the stock already heavily shorted — about 8.9 per cent of the float, on the most recent figures — which can amplify a surge when a catalyst lands. Published analyst views remain cautious: the average target sat below the new price even after the jump, with Bank of America at $3.20 and an Underperform rating and Stephens at $3, a reminder that the market's verdict and the analyst community's are not the same. Hasbro, Equifax and Northrop Grumman also rose on Tuesday.

Separately, MarketBeat's stock screener put five digital media stocks on its watch list for the highest dollar trading volume in recent sessions: Adobe, DoubleVerify, Ziff Davis, Xunlei and Townsquare Media — companies whose results turn on user growth, advertising revenue and subscription income. No notable insider buying or selling disclosures led the wires overnight; the disclosed-trades tape was quiet relative to the earnings and deal news driving the session.
