Tesla's stock (TSLA) is facing a decline today following a tough period for the company. The stock has dropped by over 6%, adding to an 8% decrease last week and marking its eighth consecutive week of falling values. This decline has led to a substantial decrease in the automaker's market worth, amounting to hundreds of billions.

One of the primary factors impacting Tesla's stock today is a recent report from China, a crucial market for the company. Tesla has announced a free trial of its Full-Self Driving (FSD) autonomous software in China from March 17 to April 16. However, this move has not allayed investors' concerns.

The offer is not exclusive to new purchasers but extends to current Tesla owners with the latest hardware and software. Tesla is facing challenges with its self-driving technology in China due to limitations on data sharing imposed by the government's data privacy regulations, preventing the company from transferring data gathered in China to its US servers.

During Tesla's Q1 earnings call, CEO Elon Musk acknowledged the challenges they face with the FSD rollout in China due to restrictions on data transfer and training. Tesla is collaborating with Chinese partners like Baidu to enhance its mapping data for the FSD system.

Tesla's FSD technology lags behind rival software from Chinese brands like Xiaomi and Xpeng. Additionally, Tesla's market position is under threat from competitors such as BYD, which is developing advanced autonomous solutions in partnership with DeepSeek AI.

In the broader context, Tesla is also encountering difficulties in Europe and a decline in brand reputation in the US. The company's challenges are not just limited to market competition but are also impacted by CEO Elon Musk's controversial actions and statements, which have led to protests at Tesla showrooms in the US and have affected his reputation in European countries.
