US stocks climb on tech and earnings outlook

U.S. stocks rose at the close of today's Tuesday session, supported by a rebound in technology shares, especially Nvidia, which recovered after seven sessions of decline amid anticipation of its upcoming quarterly earnings. Major stock indices closed higher, with the S&P 500 increasing by 0.3% and the Nasdaq gaining 0.7%. This comes after statements regarding the risk of escalating trade tensions between the U.S. and Canada, which caused volatility in shares of major tech companies. Investors are closely watching Nvidia's results, which are expected to approach $92 billion in annual revenue, though a decline is anticipated if the company fails to meet expectations.
