What does the stock market 519 curse mean?

Wednesday, May 19, 1999, is a day that will forever be remembered in the history of A-shares. On the same day, the Shanghai stock market rose 51 points and the Shenzhen stock market rose 129 points. Subsequently, under the leadership of Internet stocks, the Shanghai and Shenzhen stock markets swept away the downturn and climbed sharply. The stock index rose by 65% ??within 30 trading days. This was called the "5.19 market." Since then, the stock market has ushered in a high-tech storm led by the Internet. In the rebound on May 18, 2010, it was not technology stocks that took the lead, but real estate stocks. On this day, real estate stocks faced the severe measures to regulate the property market and launched a self-help market. The 300 Real Estate Index rose by 6.38% that day, and 10 real estate stocks hit their daily limit. Gemdale Group was the vanguard of the rebound, hitting its daily limit. China Merchants Real Estate, Poly Real Estate, and Vanke all rose more than 7%. The "519 Curse of the Stock Market" is now more about expressing the sharp rise and fall of the day and reminding everyone of the risks of the stock market. Although current investors are downplaying this understanding, history in the stock market often repeats itself. These popular slogans remind everyone to have a clear understanding of the stock market.
