Veteran technical strategist Tom DeMark has forecasted that U.S. stocks are likely to experience another decline leading to a bear market in the coming months. DeMark, who accurately predicted the market top in February and the subsequent low in April, indicated that the S&P 500 rally is expected to stall soon. He highlighted the presence of the "DeMark 9" exhaustion signal on the S&P 500, suggesting buyers could be nearing exhaustion and a potential short-term market top might be forming. This signal is part of the DeMark Sequential indicator, which is used to identify potential reversal points in the market. While some interpretations suggest the bear market may be postponed in the short to medium term, the overall outlook from DeMark points to a resumption of downward market trends. The iShares Russell 2000 ETF (IWM) and the S&P 500 index (SPX) are among the key instruments referenced in this context.
