Yesterday, the US stock market opened lower and then rose throughout the day. This week's closing will be a key point for the US stocks, determining whether the market is adjusting to a stable level and entering the late stage of a bull market or breaking below the support band and entering a bear market. Based on the market performance and certain data, this round of rally is caused by short covering accumulated after the recent decline over the past few days, and it has triggered some mechanism-driven chasing strategies. Data shows that open interest is decreasing, which is not due to major players building positions or increasing holdings to push prices up. In the short term, on the one-hour chart, the MACD indicator shows a potential bearish divergence signal, with prices continuously hitting recent highs, but the bullish volume bars are shrinking, and the KDJ lines are also showing signs of turning downward. Tonight, the strategy is not to chase the high further; instead, watch for a pullback trend.
