In a significant development for the digital advertising sector, shares of The Trade Desk, Inc. (NASDAQ: TTD) surged 14.8% in pre-market trading on July 18, following the announcement of its inclusion in the S&P 500 index. This move comes after S&P Dow Jones Indices revealed that The Trade Desk would replace ANSYS Inc. (NASDAQ: ANSS) in the S&P 500, effective from the market open on July 18 [1].

The inclusion in the S&P 500 is expected to boost the company's visibility and liquidity, as index funds typically hold a significant portion of the shares of S&P 500 components.
