"Sharp fluctuations in the stock market have been frequent recently due to multiple factors causing a huge volatility in stock prices."

Recently, after several Hong Kong stocks were included in the Stock Connect program, their stock prices initially surged significantly, but later experienced a sharp decline from their highs, with a substantial increase in volatility. The market believes that there may be multiple reasons for this phenomenon, including adjustments in index components leading to passive buying of related ETFs, the influx of "Stock Connect" funds from the mainland driving buying pressure, speculation in the market, and the fact that some newly included stocks have a relatively low number of shares available for trading due to their recent listing.
