This week's Monday coincides with Presidents' Day in the United States, and the U.S. stock market is closed. On trading days when the stock market is absent, market liquidity will decline noticeably, which typically results in more monotonous price fluctuations. However, this "calm" may hide something beneath the surface—major capital often makes bold moves when trading activity is thin.

Particularly worth guarding against is the futures market. In an environment of depleted liquidity, a single massive buy or sell order could trigger a chain reaction of stop-loss liquidations, instantly wiping out large numbers of short or long positions. In what appears to be a stable market, liquidation risk is actually most easily underestimated.

Trading Recommendations: During U.S. stock market closures, reduce leverage ratios as much as possible and be cautious with large transactions. If you lack confidence in the market movement, observe from the sidelines first. Capital preservation should always be the priority.
