For instance, Bernstein stood among the bears as the firm expects further downside for Tesla shares in the days ahead. The firm has provided an Underweight rating amid lofty valuation. The average price target from Wall Street analysts stands at $296.79, indicating more downside from the current level of $330. Tesla stock price has hit an all-time high of $500 at the end of the last month. The shares are in correction territory since the beginning of this month. The market analysts and investors have aggressively been waiting for a highly-anticipated Battery Day event that is scheduled on September 22. The forecasts and commentary related to future fundamentals would play a big role in the future price movement. Tesla also plans to introduce new vehicle designs. The company has also been aggressively working on improving its production potential and deliveries. Elon Musk last week said that the new European Gigafactory is likely to have special features. “It will be the first time that there will be a transformation in the core structural design of the vehicle. It’s quite a big thing. Both manufacturing, engineering and design as well,” Musk said.
