China is still on vacation, while gold has soared to the sky

During the Chinese holiday, COMEX Gold Futures hit a new all-time high today (breaking $2,800), with spot gold only $10 away from its historical high.
The sudden rise in gold this round is not supported by any reason.
1. In terms of timing, it occurred at the intersection of the Asian trading session and the European trading session, while previous breakthroughs occurred during the New York trading session;
2. During the same period, the US Dollar Index did not undergo any changes, indicating a lack of news, which seems to be a precautionary behavior in anticipation of something, thus naturally shifting attention to tonight's US stock market;
3. Early this morning, the Fed's 'hawkish pause in rate cuts' entered a new phase of observation, which should have been bearish for gold prices.
4. The only reasonable explanation at present is that tonight's US economic data (US GDP for the fourth quarter, initial jobless claims for last week) has been pre-hyped, with advance bets on weak US economic data (but if the data actually exceeds expectations, there will be a reversal of the upward trend). If not, then it can only be a hidden major trend emerging.
