[Analysis: Rare Disappearance of U.S. Stock Market Selling Pressure in 2026, No Extreme Sell-Off Days So Far] The Kobeissi Letter posted an analysis on the X platform, stating that the U.S. stock market in 2026 has demonstrated unprecedented resilience. This year could potentially become the first complete year in at least 30 years without a single New York Stock Exchange (NYSE) '80%+ downside-volume day.' An '80%+ downside-volume day' refers to a trading day where at least 80% of the NYSE's trading volume comes from declining stocks, which is typically considered a significant signal of widespread market selling pressure. Data shows that during the 2008 global financial crisis, the NYSE experienced 49 such trading days; during the 2022 bear market, there were 33 such days; and in 2025, there were 9 such days.
