US Stocks Surge on Treasury Rebound

US stocks saw significant gains on Monday, driven by a rebound in Treasury securities. The S&P 500 rose 0.5%, while the Dow added over 600 points. Meanwhile, the Nasdaq edged higher.

The US decision not to strike Iran over the weekend and a decline in fuel prices contributed to the market's positive mood. As a result, yields declined across the curve as investors reassessed inflationary risks, supporting credit-sensitive equity sectors.

Bank holding companies led the charge, with JPMorgan, Bank of America, Visa, and Goldman Sachs gaining over 1%. Large-cap tech companies also saw gains, with Amazon surging 5%.
