How should we view the A-share market trend on September 30, 2026?

Today is Wednesday, September 30, 2026—the final trading day before the National Day holiday. Yesterday saw extremely low trading volume; historically, there tends to be a small ‘red envelope’ (i.e., a modest rally) on the last trading day before holidays. However, given today’s dominance of algorithmic trading, past patterns are no longer reliable. Moreover, overall market liquidity remains weak—so a sharp decline is also possible. Regardless, the key takeaway is to keep your hands off the market: just stay disciplined and avoid unnecessary trading.
