Business InsiderThe cyclical bull rally starting in October 2022 is expected to last into 2025, according to Ned Davis Research.The firm highlights a chart that shows the historical trends of cyclical bull market rallies, and when they typically end."We expect to remain overweight equities, with the correction leading to a buying opportunity," it said.The cyclical bull rally that started in October 2022 is set to last well into 2025, according to historical trends highlighted by Ned Davis Research.The research firm published a note last week that included a chart illustrating prior cyclical bull rallies within a secular bull market, as is the current rally.What Ned Davis Research found is that the average rally, based on the start date of the October 2022 stock market bottom, should last into the summer of 2025.And it could last even longer into 2026 if it follows the footsteps of the 2011 to 2015 cyclical bull rally, or well into 2030 if it follows the path of the technology-fueled cyclical rally of 1990 to 1998.Ned Davis ResearchThe bullish outlook from Ned Davis Research comes amid a slight correction in the stock market, with the Nasdaq 100 falling nearly 10% from its recent peak in July.But the correction is just that, a short-term decline, and it doesn't mark the end of the bull rally, according to the note."The global soft landing evidence and accommodative monetary policies continue to bode well for long-term equity performance," Ned Davis Research said.
