When Alibaba's market value was at its highest, its market value on the Nasdaq Stock Exchange in the United States was as high as about 860 billion US dollars, and its market value on the Hong Kong Stock Exchange was as high as more than 6 trillion Hong Kong dollars. The highest share price of Alibaba Group Limited occurred on October 31, 2020, when the US stock price exceeded 319 US dollars per share, and the Hong Kong stock price reached a maximum of 309 Hong Kong dollars per share. However, Alibaba has been on a downward trend since then, and it has been falling for the whole year of 2021. It was not until the end of May 2022 that the stock price fell to its historical lowest value, and then it stopped falling and started to rebound.
