Atlassian Corporation (TEAM) shares are down approximately 11% on April 23, 2026, falling from a prior close of $71.22 to around $63.39, pushing the stock toward new multi-year lows.

Super Micro Computer (SMCI) shares are trading down approximately 10% in pre-market on April 23, 2026, following a prior close of $29.18.

ServiceNow (NOW) shares are trading down approximately 12.81% in pre-market on April 23, 2026, falling from a prior close of $103.07 to around $89.87. The primary catalyst is the company's Q1 2026 earnings report, released after the close on April 22, which revealed subscription revenue growth was dinged by a ~75 basis point headwind from delayed large on-premise deal closures in the Middle East due to the ongoing regional conflict.

Shares of IOVA are declining approximately 6.49% in Wednesday's session on April 22, 2026, falling from a prior close of $3.70 to approximately $3.46, as broad biotech sector selling pressure and risk-off sentiment weigh on commercial-stage but unprofitable biopharmaceutical companies.

Shares of SMMT are declining approximately 9.51% in Wednesday's session on April 22, 2026, falling from a prior close of $26.38 to approximately $23.87, as investors lock in gains following the stock's sharp 16.4% single-session surge on April 21. The primary driver is profit-taking after an outsized upside move: SMMT surged from approximately $22.65 to $26.38 on April 21 on renewed investor enthusiasm surrounding ivonescimab's clinical data potential and bullish institutional commentary — gains that are now partially being retraced in the absence of a new positive catalyst.

Shares of SRAD are plunging approximately 22% in Wednesday's session on April 22, 2026, declining from a prior close of $16.84 to approximately $13.13, as investors react to a combination of weaker-than-expected full-year 2025 financial results and a downward revision to the company's 2026 organic growth outlook.
