Wall Street's riskiest trades are suddenly back on top: Chart of the Day

Investors are embracing risk and reaping rewards in August, with Wall Street's riskiest trades making a comeback. In just ten trading days, Cathie Wood's ARK Innovation ETF (ARKK) has surged 14%, while IPOs, chips, and software have climbed 9% or more. Nvidia (NVDA) alone has added $600 billion in market value, SpaceX (SPCX) $420 billion, and Microsoft (MSFT) $230 billion.

The key takeaway is the diverse risk factors driving this rally. An equal-weighted combination of ARKK, Renaissance IPO ETF (IPO), iShares Semiconductor ETF (SOXX), and iShares Expanded Tech-Software Sector ETF (IGV) is outpacing the SPDR S&P 500 ETF (SPY) by nearly 7 percentage points, marking the largest early-month gain since 2015.

This surge follows years where IPOs were more of an exit strategy rather than a growth catalyst. Currently, over 70% of stocks in both the S&P 500 and Nasdaq-100 are up, with even stronger participation in the chip and software sectors. This represents a stark contrast to July, when a $3.2 trillion shift between chips and the Magnificent Seven left investors divided.

The top chart illustrates that previous risk surges led to vastly different outcomes: ARKK gained 34% more in May 2025, while SPY rose 10% over the next three months; in February 2021, ARKK suffered a 54% drop while SPY still climbed 12%. August may bring another broad risk-on surge, but history suggests that does not guarantee today's top performers will remain at the forefront.

Jared Blikre, global markets and data editor for Yahoo Finance, notes that history does not guarantee the current hottest trades will still lead when the dust settles.
