Nick Colas and Jessica Rabe on the 6 Standard Deviation Tech Event, How SpaceX Will Tell Us if It’s 1997 or 1999

The recent "mini crash" in technology stocks represents a statistically extreme event, with tech outperforming the S&P 500 by 29.3 percentage points over 50 days—a six-standard-deviation anomaly. Market-making algorithms likely amplified the subsequent sell-off due to this overextension. While semiconductors have led this rally, current data suggests a potential rotation toward software or a broader index-weighted approach. The upcoming SpaceX IPO serves as a critical market indicator; its fixed-price structure and high retail demand contrast with traditional book-building processes. Comparisons to the 1999 dot-com bubble remain premature, as current market gains lack the 84% six-month surge that characterized that era. Despite recent volatility, broader S&P 500 momentum remains intact, suggesting that while tech requires caution, the overall market environment does not yet mirror the structural breakdown of past bubbles.
