WASHINGTON — Declassified documents show the Federal Bureau of Investigation probed whether President Trump fired then-FBI Director James Comey at Russia's direction. Investors must now recalibrate the risk premium associated with potential shifts in presidential power or policy.

The broader market indices reflected cautious sentiment. The Nasdaq Composite traded down 0.8 percent to $26,363, and the S&P 500 fell 0.2 percent to $7,724. Large-cap technology stocks showed mixed performance but generally faced pressure. Microsoft traded down 1.1 percent to $487.46, while Alphabet fell 4.0 percent to $362.43.

The defense sector could emerge as a beneficiary of heightened national security concerns. Increased scrutiny of foreign influence often translates into robust defense budgets and sustained government contracts. Lockheed Martin and RTX Corp. warrant close monitoring, as their long-term revenue visibility could improve under these conditions—a clear divergence from the broader market's apprehension.

This political backdrop encourages a flight to quality. Investors typically prioritize companies with strong cash flows, established market positions and less sensitivity to regulatory upheaval. Apple, trading up 0.5 percent to $311.00, exemplifies this resilience, often acting as a defensive play within the technology sector. Capital is likely to rotate out of more speculative assets and into these perceived safe havens.

Further congressional hearings or White House responses represent concrete events that could trigger market reactions. Investors should monitor these developments closely, as they will directly influence policy stability and corporate operating environments.
