Markets watch the Fed as chip shares rise and health insurers slide on Medicare proposal

A split start for futures ahead of the Fed

U.S. index futures were uneven early Tuesday, January 27, 2026, with gains in tech-related names helping the S&P 500 and Nasdaq, while the Dow was dragged lower by steep losses in health insurance shares. Traders are also positioning for the Federal Reserve’s policy decision expected Wednesday, with markets focused on what the central bank signals about the path for interest rates in 2026.

Investors came into the day after a strong start to the week for major indexes, and with a heavy calendar of corporate earnings. The combination of major results and the Fed’s meeting has kept short-term moves sensitive to headlines, especially in sectors tied to policy and rates.

Health insurers sink after Medicare rate update

A key driver of pre-market weakness was the health insurance space. Shares of major Medicare Advantage insurers fell after a U.S. government proposal indicated only a minimal increase in payments to Medicare insurers for 2027, far below what many analysts and investors had anticipated. The surprise helped trigger broad selling across the group.

The selloff hit some of the sector’s largest names and spilled into related health-care stocks. The move underscores how sensitive the industry is to federal payment policy and how quickly expectations can reprice when new proposals arrive.

Micron boosts chips; big earnings in focus

On the upside, chip shares gained strength after Micron said it broke ground on a new manufacturing facility in Singapore, feeding optimism that capacity expansion will support demand tied to AI infrastructure and data-centric computing. Tech leadership helped offset some of the broader market caution ahead of the Fed.

Meanwhile, investors sifted through a busy earnings slate featuring major industrial and consumer-facing companies. Results and guidance have become especially important as companies navigate higher financing costs, a still-evolving demand picture, and shifting sector-level pressures driven by policy changes and regulation.

Commodities and alternative assets also drew attention: gold held near record territory after a sharp run-up, while bitcoin traded around recent highs as markets awaited the Fed’s next move. Taken together, Tuesday’s early action reflected a market balancing optimism around technology investment with renewed anxiety about health-care reimbursement and the near-term direction of interest rates.
