Investors are reaching for more risk and getting paid for it, with Cathie Wood's ARK Innovation ETF up 16% in the first nine trading days of August while IPOs, chips, and software have all jumped 9% or more. Nvidia has added about $600 billion in market value this month, SpaceX roughly $440 billion, and Microsoft nearly $240 billion, with Micron, Broadcom, and Palantir each gaining more than $130 billion. An equal-weight basket of ARKK, the Renaissance IPO ETF, the iShares Semiconductor ETF, and the iShares Expanded Tech-Software Sector ETF is beating the SPDR S&P 500 ETF by about 8 percentage points through August's first nine trading days, the basket's biggest early-month lead since 2015. Seven in 10 stocks in both the S&P 500 and Nasdaq-100 are higher this month, with participation even stronger in chips and software, a sharp change from July's $3.2 trillion rotation. The two closest historical matches to August's early risk surge ended very differently: in May 2025 the rally kept running with ARKK gaining another 36% over three months, while January 2021 was a fake-out that saw ARKK cut in half over the next year.
