History has repeatedly warned regulators and retail investors that bull markets and asset bubbles are undesirable. Bull markets are the most harmful to the market. As much money goes up as it goes down, it is a big way of cutting leeks. The future regulatory goal is to suppress asset prices and keep them at a reasonable level to avoid big ways of cutting leeks. Once they go up, there will always be people who want to take advantage of the increased liquidity to cash out. As long as the price is kept at a reasonable price, the motivation to reduce holdings and cash out will not be that strong. Stable operation is the general trend and what people want.
