SentimenTrader technical strategist Jay Kaeppel points out that despite some investors' concerns that the current AI-driven bull market may be nearing its end, according to the seven-year cycle he has identified, the stock market will enter a historically strong 18-month cycle starting October 30. Kaeppel explained in comments to clients and MarketWatch that historical data from the past 106 years show these cycles typically bring exceptionally strong stock market returns.
