Seasonality points to an S&P 500 correction starting in the August-to-September window, with the setup framed as a shallow pullback, July strength, then a bigger late-summer drop. The last three midterm years — 2022, 2018, and 2014 — are used as the template: each featured an early correction, a rally, then a 10% to 20% decline after a late-summer or early-fall top. Semis are the likely catalyst, and the same back-half weakness is tied to a possible Bitcoin cycle bottom if stocks and BTC roll over together. The video leans on the idea that 2026 YTD now resembles 2018 and 2014 more than a clean uptrend.

  • S&P 500 is framed as potentially dropping 10% to 20% starting in the August-to-September window.
  • A prior call expected a shallow June correction followed by a July rally, not a larger June top.
  • July has been green for the S&P 500 every year since 2015.
  • August and September are the S&P 500's two red months on average.
  • The seasonal setup is described as a distribution phase: shallow drop, rally back up, new highs, sideways action, then a larger drop.
  • The current pattern is said to have already had the first drop and now be rallying back up before a likely sideways phase and then a bigger late-summer decline.
  • The last three midterm years are said to match the pattern: 2022 topped in mid-August and the S&P 500 fell about 19%; 2018 topped in mid-September and fell about 20%; 2014 started its correction in September and fell about 10%.
  • Across 2022, 2018, and 2014, the common pattern is summarized as a 10% to 20% drop after a late-summer or early-fall top.
  • 2010 is flagged as an outlier: it had an August drop, but a larger decline had already happened earlier in the year.
  • 2026 YTD S&P 500 ROI is said to resemble 2018 and 2014 in the sequence of early correction, rally, then larger correction.
  • 2022 is described as more or less a bear market, but still had a rally around this time and then a correction starting in the August time frame.
  • An average of 2022, 2018, and 2014 is used to support the expectation of an early correction, summer rally, then another correction in the back half of the year.
  • The stock market is expected to stay weak for the rest of the midterm year after that back-half correction.
  • Bitcoin is expected to find its market-cycle bottom in the stock-market correction that occurs in the back half of the midterm year.
  • If Bitcoin weakens in August or September while stocks are getting the expected correction, the four-year cycle could line up and produce a major BTC market-cycle bottom, potentially alongside an S&P 500 low.
  • The likely source of the S&P 500 correction is guessed to be semis, with fears around the semiconductor industry after a run-up that has left semis pretty elevated.
