Read MoreHide Full Article

The S&P 500 Index is witnessing a strong rally, with a record high close for the third straight session. The benchmark hit a new milestone of 6,300 on July 21, driven by optimism over strong second-quarter results and signs of economic resilience, even as uncertainty around U.S. trade policy persists.

SPDR S&P 500 ETF Trust (SPY - Free Report) , the proxy version of the S&P 500 Index, has gained 8% so far this year. While many stocks in the ETF have performed well, we have highlighted five stocks that have gained more than 60% so far this year. These are Palantir Technologies Inc. (PLTR - Free Report) , NRG Energy Inc. (NRG - Free Report) , Seagate Technology (STX - Free Report) , Howmet Aerospace Inc. (HWM - Free Report) and GE Vernova (GEV - Free Report) .

Let’s take a closer look at the key drivers behind the market rally:

Strong Corporate Earnings

The second-quarter earnings season is off to a robust start, with companies not only beating estimates but also providing a favorable outlook for current business trends, which should help solidify earnings expectations for the third quarter and beyond. Earnings of the 62 S&P 500 companies that have reported so far are up 9.3% from the same period last year on 5.8% higher revenues, with 82.3% beating EPS estimates and an equal proportion beating revenue estimates, per Earnings Trend report.

Among the Mag 7, Tesla (TSLA - Free Report) and Alphabet (GOOGL - Free Report) will report results today. Total Q2 earnings are expected to be up 11.7% on 11.3% higher revenues (read: 5 Sector ETFs Set to Power Q2 Earnings Growth).

AI Boom and Tech Leadership

The ongoing AI boom continues to fuel enthusiasm for large-cap tech stocks, which have an outsized influence on the S&P 500. Investors are betting on long-term growth in AI applications across industries, boosting demand for semiconductors, cloud computing and software platforms.

Fed Rate Cut Hopes

Investor sentiment has also been lifted by increasing confidence that the Fed may begin cutting interest rates by the end of 2025.

Resilient U.S. Economy

Despite global uncertainty, the U.S. economy has shown surprising strength. June retail sales exceeded expectations, and unemployment remains near historic lows. This economic resilience is giving investors confidence that earnings growth can be sustained into the second half of the year.
