On Tuesday, the stock market experienced a broad and significant rally, with the S&P 500 closing above 7,700 for the first time. This surge was fueled by a combination of factors, including optimistic comments from Treasury Secretary Scott Bessent regarding Iran, surprisingly strong corporate earnings, a unified rally across the tech sector, and a crucial technical breakout in index levels, alongside the unwinding of speculative positions following the ‘Leopold low’.
Wall Street witnessed a monumental surge on Tuesday as a confluence of factors ignited a broad-based rally, sending stocks soaring to unprecedented levels.
The Dow Jones Industrial Average skyrocketed over 900 points, marking its strongest performance in nearly two months. The S&P 500 leaped almost 2%, establishing a new all-time high and achieving one of its most significant single-day advances of the year.
Paul Hickey, co-founder at Bespoke Investment Group, observed, "It's not just one specific news event that's causing the rally. You're getting a succession of events. Multiple positive catalysts tend to have longer legs."
Here are the five key drivers behind the market's explosive take-off:
1. Treasury Secretary Bessent's Optimistic Iran Remarks
Treasury Secretary Scott Bessent offered hopeful comments to CNBC's "Squawk Box," suggesting a potential deal with Iran could be reached either Tuesday or Wednesday to reopen the Strait of Hormuz. "We are in talks with the Iranians," Bessent stated in a Tuesday morning interview. "There is a chance we may have a deal today or tomorrow to open the strait and move towards a more normalized position in this conflict."
Following his remarks on the Strait of Hormuz, a critical choke point for global crude trade, Dow futures surged. Oil futures subsequently tumbled, providing further impetus for the equity rally and easing concerns over bond yields.
Jeff Krumpelman, chief investment strategist at Mariner, noted that the market appears to be "assuming that we're going to be able to handle the closing of the Strait of Hormuz just fine" and anticipates oil prices will stabilize long-term. However, he cautioned that a prolonged conflict pushing oil to $150 per barrel could still pose a significant headwind.
Larry Tentarelli, chief technical strategist at the Blue Chip Daily Trend Report, emphasized that Iran headlines will likely continue to sway the market. While Tuesday's news provided a boost, investors should remain prepared for volatility if tensions escalate again.
2. Explosive Corporate Earnings
A robust earnings season has consistently bolstered investor confidence this year, with second-quarter results proving particularly strong. The S&P 500 is on track to report an impressive 27% year-over-year earnings growth for Q2, excluding adjustments from Google-parent Alphabet and Amazon, according to Bank of America Securities. This figure represents a 4% beat compared to consensus expectations at the start of the earnings season.
"War continues to get shrugged off," commented Jay Woods, chief market strategist at Freedom Capital Markets. "Earnings are finally winning."
Including Alphabet and Amazon, the broader index's earnings growth jumps to an even more incredible 45% year-over-year, Bank of America highlighted. Krumpelman added, "Have you checked out the earnings growth rates in healthcare, industrials, financials, consumer [staples], and these other areas? It's strong double digit. That will support further advancement in the market."
While S&P 500 companies have recently seen less reward for exceeding earnings expectations, with stocks averaging a 0.2% slip the day after reporting, this trend may be reversing. Post-earnings ascents by Caterpillar and Palantir on Tuesday further reinforced market confidence.
3. Broad-Based Tech Sector Rally
Recent months saw a divergence within the high-flying technology sector, with chip stocks initially benefiting from AI hype while megacap tech like Microsoft and software companies lagged. This reversed in July as chip stocks experienced a correction. However, August, particularly Tuesday, saw investors broadly buying tech, fueled by optimism that all segments can profit from AI.
The iShares Semiconductor ETF (SOXX) surged over 6% on Tuesday, while the iShares Expanded Tech-Software Sector ETF (IGV) gained nearly 5%. Both groups significantly contributed to the sector's momentum, driving the tech-heavy Nasdaq Composite up more than 2.5%.
Even the 'Magnificent Seven' megacap stocks, which had been the primary drivers of market gains in previous years, joined the rally, with the Roundhill Magnificent Seven ETF (MAGS) rising almost 1%. Despite this, the fund's 5% year-to-date gain still lags the S&P 500's 13% advance, indicating its recent underperformance. The rebound in technology stocks also follows a period of challenges, with the more concentrated Nasdaq 100, which jumped over 3% on Tuesday, having entered a shallow correction last week.
4. Significant Index Breakout
The S&P 500 decisively breached a critical resistance level, igniting further buying. Technical analysts had closely monitored the 7,620 level, representing the June high. On Tuesday, the broad market index opened above this threshold and sustained its momentum, closing above 7,700 for the first time ever.
This consistent buying streak strengthens conviction in the rally's sustainability. Historically, four consecutive days of greater than 1% gains in the Nasdaq Composite often presage further advances, according to Bespoke's Hickey. "The fact that you get such consistent buying four days in a row suggests that it's real buying," Hickey commented.
Krumpelman projects the S&P 500 could reach 8,100 by year-end and 8,400 by mid-2027. "I'm going to take my cues from the trend in earnings, inflation, employment, real GDP growth, credit spreads, and as long as they're trending in the right direction as they are now, then my targets will hold," he stated.
5. The 'Leopold Low' Effect
Another factor contributing to the market's readiness for a bounce like Tuesday's was the near-collapse of Leopold Aschenbrenner's Situational Awareness fund. This fund had peaked at around $45 billion in July, fueled by surging memory and momentum stocks. However, under pressure, Aschenbrenner was forced to sell his leveraged stock bets to Citadel last week.
This event signaled a washout among momentum investors by the end of July, leading to technical selling. With speculative, high-volatility trades cleared and the Nasdaq 100 having corrected from its highs, traders were primed to re-enter the market at the start of the new trading month.
Jeff Kilburg, investing chief at KKM Financial, termed this the "Leopold low." He explained, "The algorithmic selling the last two weeks before Aschenbrenner's forced sale in these momentum names was like something I've never seen before. We finally got rid of the bullying shorts in the momentum names that pushed the Nasdaq 100 into a correction. And once we got rid of this Wall Street noise, the focus turned back to earnings growth and we are seeing the best growth we've seen in decades."
Following Tuesday's robust rally, the S&P 500 is now up 3.3% for August, and the Nasdaq Composite has gained nearly 5% in just two days.
