The S&P 500 (SPX) has already delivered double-digit total returns in 2023, 2024, and 2025, and is up around 10% year to date in 2026. That sequence places U.S. large-cap equities in a late-cycle style performance cluster that historically has not been common.
Historically, the clearest analogue for an extended string of strong S&P 500 (SPX) gains came in the late 1990s, when the index produced five straight double-digit years from 1995 to 1999 before the Dot Com Bust. In that period, broad U.S. stock benchmarks such as the S&P 500 (SPX) and Nasdaq Composite (^IXIC), along with tech-focused sector exposures like XLK, ultimately experienced a multi-year drawdown.
Other strong multi-year runs in the post-war era did not always lead to a similar collapse, however. The 1940s-1950s advance in the S&P 500 and the 1982-1987 bull market, despite powerful gains, were followed by either more moderate corrections or shorter, quickly retraced crashes.
This mixed history suggests that a potential four-year double-digit streak would be a necessary but not sufficient condition for a major unwinding in broad U.S. stock benchmarks. Additional features such as stretched valuations and concentrated speculative excess, particularly in growth and technology segments akin to QQQ and XLK during 2000-2002, have tended to determine whether the aftermath resembled a full bubble unwind or a standard correction.
If the S&P 500 ultimately finishes the current calendar year with a gain of 10% or more, vehicles directly tracking the index, such as SPDR S&P 500 ETF Trust (SPY), Vanguard S&P 500 ETF (VOO), and iShares Core S&P 500 ETF (IVV), would sit at the center of any subsequent repricing. Growth-heavy benchmarks similar to the Nasdaq-100 (NDX), tracked by Invesco QQQ Trust (QQQ), have historically shown amplified downside when prior multi-year strength coincided with tech-driven exuberance.
