[BRIEFING.COM] The S&P 500 (-0.68%) is in second place on Wednesday afternoon, down about 47 points.

Briefly, S&P 500 constituents AppLovin (APP 384.45, -77.34, -16.75%), Boston Scientific (BSX 78.15, -13.47, -14.70%), and Amphenol (APH 130.47, -16.59, -11.28%) dot the bottom of the average. APP leads losses as investors fear credible AI-driven disruption to the mobile ad stack could erode AppLovin's core monetization moat, with the selloff amplified by crowded positioning and a broader software risk-off move, with BSX sliding despite beating Q4 EPS and revenue, as investors reacted to cautious FY26 guidance that slightly misses consensus and signals slower-than-expected near-term growth.

Meanwhile, Fortive (FTV 60.84, +6.49, +11.94%) is atop the standings after beating Q4 EPS and revenue expectations and issuing FY26 guidance above consensus, with strong execution, accelerating growth, and significant share buybacks boosting investor confidence.
