Live DOW Chart
A strong semiconductor rally propelled several important indexes to new record highs, but the S&P 500, Nasdaq, and Dow Jones concluded a turbulent afternoon with mixed results.
S&P 500 and Nasdaq Extend Record-Breaking Rally
The broader U.S. stock market continued climbing higher, with both the S&P 500 and Nasdaq Composite closing at new all-time highs as investor enthusiasm surrounding semiconductor and AI infrastructure stocks remained strong.
The S&P 500 closed at 7,519.08, gaining 45.59 points or 0.61%, surpassing its previous record close from May 14 at 7,501.25.
Meanwhile, the Nasdaq Composite rose 312.21 points or 1.19% to finish at 26,656.18, also setting a fresh record after breaking above its prior high of 26,635.22.
Technology and semiconductor names remained the dominant drivers of momentum as investors continued rotating into companies tied to AI infrastructure, memory demand, and data-center expansion.
Dow Jones Ends Lower Despite Broad Market Strength
In contrast, the Dow Jones Industrial Average finished lower on the day despite recently reaching a record high earlier in the week.
The Dow declined 118.01 points or 0.23% to close at 50,467.06, weighed down by weakness in several defensive and industrial names even as growth-oriented sectors pushed higher.
The mixed performance highlighted the market’s continued preference for technology and semiconductor exposure over more traditional cyclical sectors.
Russell 2000 Posts Strongest Gain
The standout performer of the session was the Russell 2000, which surged 51.31 points or 1.79% to close at 2,920.54, marking another record finish.
The strong move suggested improving risk appetite beyond large-cap technology stocks, with investors increasingly rotating into smaller growth-oriented companies as market sentiment improved.
Micron Leads Powerful Semiconductor Rally
One of the biggest catalysts behind the rally came from Micron Technology, which exploded higher by 19.29% to close at $895.88.
The stock traded in an enormous intraday range between $820.30 and a record high of $916.76, reflecting aggressive buying activity following bullish commentary surrounding memory demand and AI-related infrastructure spending.
Micron’s surge helped lift the broader semiconductor sector, with related companies including Advanced Micro Devices, Western Digital, Marvell Technology, Lam Research, and Texas Instruments also moving sharply higher.
Airlines Gain as Oil Prices Ease
Outside of technology, airline stocks also attracted buyers as lower oil prices boosted sentiment across the sector.
Companies including American Airlines, United Airlines, and Alaska Airlines advanced during the session amid hopes that easing Middle East tensions could help stabilize energy markets and reduce fuel cost pressures going forward.
