Investors are increasing their risk exposure and are being rewarded with positive returns. In just the first nine trading days of August, Cathie Wood's ARK Innovation ETF (ARKK) has surged 16%, while new issues, semiconductor, and software sectors have all gained over 9%.

The market's performance is also impressive in terms of market capitalization increases. Nvidia has added approximately $600 billion to its market value this month, SpaceX has seen its value rise by about $440 billion, and Microsoft has added nearly $240 billion. Meanwhile, Micron, Broadcom, and Palantir have each seen their market caps grow by more than $130 billion.

Yahoo Finance analysis, based on AlphaSpace data, indicates that ARKK, the new issues sector, and the chip and software sectors have recorded their largest excess returns relative to the S&P 500 Index for the early part of any month since 2015.

Notably, multiple types of risk assets are strengthening simultaneously. An equal-weighted portfolio consisting of ARKK, the Renaissance IPO ETF (IPO), the iShares Semiconductor ETF (SOXX), and the iShares Expanded Tech-Software Sector ETF (IGV) has outperformed the S&P 500 ETF (SPY) by approximately 8 percentage points in the first nine trading days of August. This represents the portfolio's largest lead over the S&P 500 in the early part of a month since 2015, the first full year all four funds were actively traded after ARKK's launch.

The resurgence of the new issues market is particularly striking. In recent years, initial public offerings had increasingly become an exit strategy for mature private companies rather than the start of a growth story. Software, chips, technology disruptors, new issues, and the Magnificent Seven are all moving higher, while Chinese tech stocks are weakening. This rally is characterized by broad participation among individual stocks.

This month, 70% of stocks in the S&P 500 and Nasdaq 100 have risen. The breadth of the rally is even more pronounced in the chip and software sectors: the table shows the percentage of stocks in each sector that are up and the percentage that have risen more than 10%. For chips, 85% are up, with 52% up more than 10%. For software, 89% are up, with 49% up more than 10%. In the Nasdaq 100, 71% are up, with 28% up more than 10%. In the S&P 500, 70% are up, with 13% up more than 10%.

This starkly contrasts with July's market conditions. In July, a massive $3.2 trillion in capital was shuffled between chip stocks and the Magnificent Seven, forcing investors to choose one or the other. Now, in August, capital is being deployed across a wide range of sectors.

A review of historical data shows two previous periods with a similar surge in risk assets in early August, but they had very different outcomes. In May 2025, the uptrend continued. Over the following three months, ARKK rose another 36%, while SPY gained about 10%. In January 2021, it was a bear market rally. The S&P 500 continued to climb, but the highly speculative leaders of the rally ran out of steam. Within the following year, ARKK's share price was cut in half.

August's current move could signal a new broad-based risk-on window. However, historical experience suggests that even a broad rally does not guarantee that today's hottest trades will still be leading the market when the rally ends.
