In August, Wall Street's "Bull Market" Returned, and So Did the "Speculative Spirit"

U.S. stocks staged a strong rebound in August, with the S&P 500 refreshing its historical highs as investors returned to the tech and leverage sectors. Strong corporate earnings and cooling inflation provided fuel, but soaring oil prices, elevated long-term bond yields, and conflicting cross-asset signals have made this "Golden Age" trade increasingly fragile.

After chip stocks were heavily sold off in July, market fear came quickly and left just as fast. The S&P 500 has risen about 4% month-to-date, touching above the historical high of 7,800 points this week; the Nasdaq 100, which had briefly fallen into a technical correction, is now only 2.5% away from its June peak. This week, both Citigroup and JPMorgan Chase raised their year-end 2026 targets for the S&P 500, underscoring the recent bullish sentiment.

Capital continues to flow in. According to custody data from State Street Bank, which tracks over $50 trillion in institutional assets, institutional demand for U.S. information technology stocks has risen to a five-year high in the past month. Meanwhile, speculative instruments such as leveraged ETFs and call options are regaining popularity, with both retail and institutional investors increasing their risk exposure.

However, the rapid return of bullish bets has alerted some analysts—the market's current pricing of an "everything is perfect" scenario leaves almost no room for error.

Earnings Season Provides Engine, Citigroup and JPMorgan Raise Targets

The core driver behind this rebound is an earnings season described by analysts as "incredible."

Second-quarter earnings for S&P 500 components grew by over 50% year-over-year. Even after excluding investment gains from Amazon and Alphabet, the growth rate was approximately 30%, which remains strong. Scott Chronert, Head of U.S. Equity Strategy at Citigroup, raised his year-end target to 8,100 points this week, stating that "this magnitude of earnings beat is something you rarely, if ever, see." Dubravko Lakos-Bujas, Global Market Strategist at JPMorgan Chase, wrote in a client report that the U.S. equity "earnings landscape remains strong and broadly distributed across sectors," with the performance of some mega-cap cloud computing companies showing early signs that their massive AI investments are beginning to monetize. The bank raised its year-end target for the S&P 500 from 7,800 to 8,000 points, implying a 16.5% gain for the index within the year.

Kevin Gordon, Head of Macro Research and Strategy at Charles Schwab, stated, "Given the extent to which the tech sector can influence the index, this is the new normal." Nevertheless, analysts have also noted that earnings growth is spreading to other sectors of the economy, which is seen as a healthy sign for the continuation of the bull market.

Chips and Leverage Sectors Both Stage Strong Rebounds

Leading the rebound were precisely the sectors that suffered the worst declines in July.

Super Micro Computer has risen about 38% month-to-date in August, memory company Sandisk is up over 33%, and cloud computing firms CoreWeave and Nebius have each risen more than 40% in the past two weeks; Micron and Intel have also both risen by about 15%.

The leveraged ETF market has also seen a major return of "speculative spirit." According to Bloomberg Intelligence data, leveraged index funds have generated nearly $50 billion in wealth year-to-date, while single-stock leveraged funds have lost about $4 billion in the same period. This stark contrast reveals a harsh reality: broad-based leveraged strategies betting on a continued rebound have outperformed, while strategies attempting to amplify the gains of single hot stocks have been severely hit.

James Seyffart, ETF Analyst at Bloomberg Intelligence, pointed out:

"Single-stock products carry higher risk and volatility, making investors more prone to getting burned. But this sector is so new, with new products launching almost daily, that people just keep buying."

Among the most popular products, the Direxion Daily Semiconductor Bull 3X ETF, with assets under management of $25 billion, attracted the most inflows despite falling about 20% in the past month; the Direxion Daily TSLA Bull 2X ETF, despite losing over 50% year-to-date, also ranked among the top in terms of inflows. Adam Phillips, Chief Investment Officer at EP Wealth Advisors, stated that retail investors have recently shown characteristics of "disciplined buying" amidst volatility, "to some extent, becoming the smart money."

Cooling Inflation Compresses Rate Hike Expectations, Dollar Weakens

Adding macroeconomic fuel to this rebound was a series of inflation data coming in below expectations.

U.S. CPI in July increased by about 3.4% year-over-year, with core inflation continuing to decline; July PPI was flat month-over-month, lower than expected; July retail sales fell 0.6% month-over-month, the largest drop in over a year. These data prompted traders to significantly cut their bets on further Federal Reserve rate hikes, with the probability of a hike in September plunging from 75% at the end of July to about 25%.

The U.S. Dollar Index subsequently fell to a three-month low, wiping out all gains brought by the hawkish path since Fed Chair Walsh took office. Michael Metcalfe, Head of Macro Strategy at State Street Bank, believes that the U.S. tech trade is "bulletproof, at least for now"—"Amidst geopolitical and economic noise, earnings remain so strong, reinforcing the judgment that this is a structural trade, not a cyclical one."

Derivatives Market "Bullishness" Returns, Hedging Demand Falls to One-Year Low

Movements in the options market also confirm the shift in sentiment.

According to Cboe data, the Skew Index for the S&P 500—which measures the cost difference between hedging downside risk and call options—fell to a one-year low in early August. Mandy Xu, Head of Derivatives Market Intelligence at Cboe, stated that investors "sold off hedging instruments and turned to chasing call options to pursue the rebound."

Meanwhile, the VIX Fear Index declined for the fourth consecutive week, even as oil prices soared, tensions in Iran remained high, and long-term Treasury yields stayed elevated. This sends a clear signal: the market believes that almost every piece of bad news contains its own bullish hedge—weak employment means the Fed won't raise rates, slowing consumption means the Fed won't raise rates, rising oil prices are considered temporary, and AI earnings are sufficient to overshadow everything.

Multiple Contradictory Signals Emerge, "Goldilocks" Narrative Faces Test

However, the divergence in asset prices is widening and cannot be ignored.

Oil prices surged about 6% this week, with Brent crude approaching $90 per barrel, mainly due to stalled negotiations in the Strait of Hormuz and escalated U.S. threats of sanctions.

Meanwhile, this week's 30-year U.S. Treasury auction cleared at the highest yield in 25 years, and the 10-year auction yield was also at historical highs; although short-term rates declined as expectations of Fed rate hikes receded, long-term rates continued to rise, pushing the term premium to high levels and significantly steepening the yield curve.

This means: the market may believe the Fed has basically finished raising rates, but it does not believe inflation has ended.

Henry Allen, Macro Strategist at Deutsche Bank, warned that "the market is currently pricing in a Golden Age combination: growth remains strong, central bank rate hikes are limited, supply shocks prove to be temporary, and oil prices fall again." He said, "This leaves almost no room for error. It is hard to imagine these entirely benign conditions holding simultaneously."

Michael Contopoulos, Head of Multi-Asset Macro Investing at Janus Henderson Investors, also stated that while strong fundamentals and overweighting equities are reasonable, "chasing crowded and expensive market segments is a huge risk that we will avoid."

Currently, a game between "Goldilocks" and Treasury bears is taking shape. The stock market is betting on a soft landing and an AI earnings supercycle, while the long end of the bond market is pricing in fiscal deficits and supply pressures; both cannot be correct simultaneously. Which side ultimately prevails may become the most important market theme in the second half of 2026.
