Interesting market linkage has emerged. The A-shares just broke through 4000 points, and US stock futures are also opening high and moving higher. Bitcoin's price has also rebounded accordingly. But is this a true reversal or just a rebound? From a technical perspective, the synchronized strength across multiple markets does indeed send some optimistic signals, but whether the trend has fully reversed depends on the performance in the next few days. In the short term, the enthusiasm for US stock futures may be fueling the momentum, bringing some popularity to risk assets. However, don't get too excited; such correlated movements often fluctuate quickly—downward moves can be just as deadly. It's still crucial to keep an eye on key price levels for support or resistance.
