Jack Ma, the founder of Alibaba, made headlines after a prolonged absence from the public eye, sparking a positive response from investors as he sent out an encouraging memo to employees. Since 2020, Ma has kept a low profile following remarks critical of the Chinese government's policies towards tech firms, leading to a period where he was not seen publicly for over three months. In late 2023, he returned to the business scene by starting a pre-packaged meals company. The recent surge in Alibaba's stock price by 2% to nearly $75 came after Ma's message to his team, highlighting the formation of a strong team amidst external and internal challenges. His return is seen as a boost for Alibaba, especially after its major overhaul in 2023 to align with China’s anti-monopoly vision. Despite this, Alibaba’s shares are much lower than their peak in 2020. This resurgence of Jack Ma has brought again Alibaba and China's e-commerce dynamics, including concerns over "possible espionage" in Europe, into the spotlight.
