US stocks hit quarter-end with their best gains in years, thanks to a fresh rally driven by factors ranging from easing US-Iran tensions to relentless enthusiasm for technology and artificial intelligence. #### Performance of Major Indexes The major indexes rose significantly on Tuesday, with the Dow Jones Industrial Average posting a nearly 9% gain for the first half of the year. This marks the index's best first-half performance since 2021, when the pandemic stock rally began. The Nasdaq 100 ended the quarter with a remarkable 18% gain—the best three-month stretch since the pandemic, and the second-best quarter for the index in about 25 years. The year-to-date performance of the tech-heavy Nasdaq 100 stands at almost 19%. Meanwhile, the S&P 500 also saw a 9% increase, while the small-cap Russell 2000 posted an impressive 21% gain, its best first half since 1991. #### Factors Influencing Market Dynamics The first half of 2026 has been characterized by volatility, with stocks initially shaken by geopolitical tensions, notably the US-Iran conflict. By late March, major indexes had seen a drop of around 10%, followed by a record-breaking rally. Michael Hewson, a senior market analyst at iForex Europe, noted that despite the challenging start, the markets have seen a complete reversal. #### Peace Deal and Market Sentiment Investors are growing more optimistic about the resolution of the US-Iran conflict, especially after a preliminary peace agreement was reached this month, a key factor for the market. Recent announcements from both the US and Iran regarding the cessation of strikes and safe passage for commercial ships through the Strait of Hormuz have further alleviated concerns, leading to positive sentiments in the market. #### Performance of Tech Stocks The technology sector, particularly chip and memory stocks, have emerged as top performers this year, driven by intense focus and investment in AI hardware. The Philadelphia Semiconductor Index is on track to achieve its best quarter ever, having surged 80% since March. Although major tech stocks have faced challenges this year, they have still managed to lead the market's rebound. #### Overall Earnings Strength US corporations have posted robust earnings, significantly surpassing Wall Street's expectations, which has fueled the rally as the quarter concludes. By early June, around 85% of S&P 500 firms beat earnings estimates—the highest percentage recorded for a second quarter in five years, paving the way for an impressive anticipated 23% earnings growth year-over-year for the current quarter. #### Future Outlook Looking ahead, analysts project a 21% price increase in the S&P 500 over the next 12 months, with strong performance anticipated across all sectors of the benchmark index, all expected to gain at least 10% according to FactSet's reports. As the market continues to navigate through recovery and growth, investor sentiment remains cautiously optimistic. ### EXPLORE MORE POSTS [![US Market Summary for August 27, 2026](https://resources.quantel.ai/hubfs/Partners%20images/iStock-2260783305.jpg)](https://resources.quantel.ai/daily-market-summary/us-market-summary-2026-08-27) #### US Market Summary for August 27, 2026 #### Market Overview The US stock market closed higher on Thursday, driven by...
