A sharp selloff in chip stocks failed to deter the broader market and instead acted as a signal for investors to buy the dip. Semiconductor ETFs, high-yield bonds, and Bitcoin ETFs simultaneously attracted capital, indicating a broad rise in risk appetite. Although high US Treasury yields continue to exert pressure, investors are betting with real money that this adjustment is merely a temporary pullback, not the end of the risk-on cycle.
A wave of worries—including a chip stock rout, surging bond yields, and ongoing geopolitical conflicts—is growing on Wall Street. However, capital flows tell a starkly different story. Last week, the S&P 500 hit a new all-time high, and the Nasdaq 100 recorded its largest single-week gain in two months. Simultaneously, high-yield bond funds saw net inflows of $40 billion over the week, the highest in two years, while Bitcoin ETFs attracted $5 billion in net inflows over five trading days. The Bank of America Bull & Bear Indicator rose to its highest level since 2021, signaling a complete shift toward optimism within market sentiment.
This surge occurred in the aftermath of the blow-up at Situational Awareness, an AI-focused hedge fund founded by "Silicon Valley stock god" Leopold Aschenbrenner. The incident had once pulled the Philadelphia Semiconductor Index down 29% from its June peak. Yet, instead of retreating, investors viewed the turmoil as a buying signal, injecting over $110 billion into semiconductor ETFs within just two trading days, which subsequently triggered a sharp rally in the related funds.
The Semiconductor Rout Becomes a Buying Signal
The blow-up of Situational Awareness was the most dramatic event in recent markets. The struggles of this AI-themed hedge fund dragged the Philadelphia Semiconductor Index 29% lower from its June peak, triggering violent volatility in tech stocks. However, the market's reaction ran counter to traditional risk-off logic. According to Bloomberg data, the Direxion Daily Semiconductor Bull 3X ETF, a triple-leveraged semiconductor fund, attracted over $20 billion in inflows within just two trading days, subsequently gaining more than 50% over the following seven trading days. The two largest non-leveraged semiconductor funds collectively absorbed over $70 billion in the same period, each rising about 16%.
Michael O'Rourke, Chief Market Strategist at JonesTrading, characterized this as a "tsunami" of momentum buying. "The Situational Awareness event created a local low point for AI trading, unleashing a massive wave of momentum chasing," he said. "However, it's worth noting that many investors are still concentrated in mega-cap stocks, and the 'Magnificent Seven' remain the primary drivers of the index's rise."
Risk Appetite Broadly Heats Up from Retail to Institutional Investors
The market's momentum was fueled not only by the rebound in chip stocks but also by a broad capital influx across asset classes. According to Bloomberg citing Bank of America data, high-yield bond funds saw net inflows of $40 billion last week, the largest single-week amount in two years. Bitcoin ETFs recorded net inflows of $5 billion over the five trading days through last Thursday, despite Bitcoin prices having traded sideways in a narrow range for months. In the stock market, investors poured over $110 billion into leveraged and non-leveraged semiconductor ETFs last week. The Bank of America Bull & Bear Indicator subsequently rose to its highest level since 2021. A team led by strategist Michael Hartnett noted that the stock rally has broadened from the core tech sector, with strong inflows into high-yield bonds and narrowing credit spreads jointly supporting this optimism.
Garrett Melson, a portfolio strategist at Natixis Investment Managers Solutions, believes current market fears are overblown, and the fundamentals of risk assets remain solid. He maintains an overweight position on US stocks, focusing on large-cap tech stocks, while keeping an underweight position on fixed income, with a moderate allocation to longer duration and selective credit exposure. "Ultimately, economic growth is performing well," Melson said. "Sentiment and positioning can sometimes become extended, but this overheating is localized. Rotation helps digest excess bubbles while maintaining support for the index."
The Shadow of High Yields: Bond Market Pressure Persists
The risk-on rally is not unfolding in a carefree environment. Although the 30-year US Treasury yield has fallen on four of the last five trading days, it remains hovering near its highest levels in nearly two decades, creating a significant background pressure for the market. Analysts are divided on the cause of the high yields. Some attribute the late-July yield surge to Federal Reserve Chair Kevin Warsh's deliberate avoidance of clear interest rate guidance, which raised doubts about the central bank's commitment to fighting inflation. Others argue that the bond market's movement reflects investors' confidence in sustained economic expansion. Last Friday, the US Labor Department reported that US employers unexpectedly cut jobs in July, and data for the previous two months was also revised downward. This surprisingly weak jobs report instead boosted the stock market, causing bond yields to fall as markets bet the Fed would not be forced to raise rates in the near term.
Lindsay Rosner of Goldman Sachs Asset Management stated that as data becomes clearer and oil prices stabilize, the overall economic picture and the return on capital expenditure are becoming more defined. "Given what we've seen, the economy remains strong, and the market is gradually adapting to the current AI supply and price discovery for the future," she said. Ayako Yoshioka, Senior Investment Strategist at Wealth Enhancement, cautioned that while semiconductors remain central to AI infrastructure construction, as the process advances, the bottleneck may shift to a shortage of electricity supply. "Higher yields are still a risk—especially as AI infrastructure buildout continues to knock on the door of the bond market," she said.
Brief Pullbacks Repeatedly Reinforce Bullish Confidence
Underpinning current market sentiment is a repeatedly validated investor psychology: every pullback is brief, and every panic is a buying opportunity. Nathan Thooft, Senior Portfolio Manager at Manulife Investment Management, pointed out that price corrections have repeatedly proven to be fleeting, which continuously strengthens investors' psychological confidence. Those who chose to exit at times of highest uncertainty have paid the price, as the biggest gains often occur precisely when the market is most volatile. "There is still no compelling alternative," Thooft said. "Cash might feel safe, but in the long run, it struggles to outpace inflation and the type of earnings growth that stocks provide. As for bonds, we believe the term premium is still undervalued. Over the past decade, investors who kept waiting for a better entry point have mostly been left behind by the market."
The Cboe Semiconductor ETF Volatility Index fell nearly 9 points this week, its largest single-week decline of the year, vividly illustrating the market's rapid recovery in sentiment. Although the list of worries continues to grow, the direction of capital flows still clearly points toward risk assets.
