Afternoon direction: Cautiously short. Technical indicators (MA, MACD, volume and price) show a resonance leaning bearish, and short-term capital outflows, with the price near a key support level, indicating a downward testing demand. However, considering medium to long-term capital inflows and the key support level, the downside space may be limited, so caution is required. Entry timing: Aggressive strategy: If the price rebounds to around 81,260-81,360 (the overlapping resistance zone of MA20 and MA5) and stalls, consider entering a small short position. Conservative strategy: Wait for the price to effectively break below the first support level of 80,719 (or the lower band of Bollinger Bands at 80,816), accompanied by increased trading volume, which can serve as a confirmation signal to enter a short position. Stop-loss setting: Stop-loss should be set above key resistance levels. It is recommended to set it at 81,790 (above R1 resistance level), or based on personal risk preference, about 3% above the entry price (for example, if entering at 81,200, set the stop-loss around 83,600). Target price: The first target looks toward the second support level at around 80,152, with an expected return of about 1.3%. If broken, look toward 79,654 (the third support level), with an expected return of about 1.9%. Since the return expectation does not reach the ideal target of 5%, this trade is more suited for short-term swing trading, requiring quick entries and exits, with strict stop-loss.
