Analysts say there are two reasons for the sudden drop in A-share prices at the end of the trading day

On March 27th, in the last half hour of A-shares, the originally upward market suddenly plummeted, with the Shanghai Composite Index shrinking by 1.26% and the ChiNext Index falling by 2.81%. Analysts believe that the main reasons for the sharp decline in the late trading session are twofold: firstly, in peripheral markets, the Bank of Japan led to a strengthening of the US dollar, a weakening of the Japanese yen, and a subsequent decline in the Chinese yuan, resulting in the outflow of foreign investment. Secondly, today is the ETF option settlement day. This may be the main reason for the late game diving. The settlement date for ETF options is the fourth Wednesday of each month. If that day falls on a statutory holiday, it will be postponed accordingly. And today happens to be Wednesday. Generally speaking, the risk on the settlement date of options is not small. For example, February 28th was also the settlement of options, and the market experienced a sharp drop.
