Breadth Washouts And Year-End Rallies

Historical episodes show that when T2108, the percentage of NYSE stocks above their 40‑day moving average, falls toward 20% or lower after an extended decline, broad equities often enter a bottoming phase rather than the start of a deep bear market. These conditions have typically aligned with correction or shallow bear market environments rather than systemic crises.

In prior cycles such as the 2011 eurozone scare, the 2015 China devaluation shock, and the 2018 tariff-driven selloff, compressed breadth readings coincided with the tail end of sizeable drawdowns in SPY, QQQ, IWM, and other major index ETFs. Subsequent advances frequently unfolded over the following 2-4 months, often into the seasonally stronger part of the calendar.

During these recoveries, mega-cap leaders like Apple (AAPL) and Microsoft (MSFT) tended to outperform as flows returned to broad index and technology exposures. High-beta beneficiaries such as NVIDIA (NVDA) and financial bellwethers like JPMorgan (JPM) also historically participated, reflecting renewed risk appetite once breadth extremes had marked or closely preceded important lows.

The pattern remains statistical and conditional rather than deterministic, with several counterexamples where low T2108 readings did not quickly transition into strong rallies. Outcomes have depended heavily on whether the macro backdrop resembled a manageable growth scare or an unfolding recessionary or credit-driven downturn, underscoring the importance of distinguishing corrections from structural bear markets when interpreting breadth washouts.
