What stands out

The clip highlights three abrupt market moves driven by company-specific news: Carnival lifted its full-year adjusted earnings-per-share forecast and rallied, CarMax reported stronger-than-expected used-vehicle sales and plans to resume buybacks, and FICO plunged after a regulator made it easier for lenders to use an alternate credit score. The FICO drop is notable because it is the largest intraday fall in the available data back to 1988, creating immediate trading volatility and a broader question about competitive pressure in the credit-scoring market.
