Stock Market Update

[BRIEFING.COM] The S&P 500 (-0.52%) is today's worst-performing average, down now about 30 points.

Briefly, S&P 500 constituents Fair Isaac (FICO 2034.30, -171.71, -7.78%), United Airlines (UAL 75.78, -2.84, -3.61%), and Norwegian Cruise Line (NCLH 18.25, -0.66, -3.49%) pepper the bottom of the average. FICO falls after FHFA Director Pulte signaled support for moving from a tri-merge to a bi-merge credit model in mortgage underwriting, criticizing FICO's costs and implying potential changes ahead, while UAL's declines are likely due to concerns about reduced capacity at Newark Liberty International Airport (EWR) — a key hub for United.

Meanwhile, Moderna (MRNA 28.50, +2.11, +8.00%) is outperforming after FDA leaders signaled support for approving annual COVID-19 boosters for high-risk groups based on immunogenicity data, streamlining the regulatory path for its core market. The shift away from broad low-risk approvals allows Moderna to focus on a more predictable, commercially viable segment, potentially boosting investor confidence in its long-term COVID vaccine revenue.
