With the first day of winter here, it’s a good reminder of how close we are to many publicly traded companies closing out their fourth calendar quarters. For Tesla (NASDAQ:TSLA), these last 10 days will be important, as they’ll help determine how many electric vehicles the company delivers during the final quarter of the year.Expectations for the quarter are high. Tesla has seen massive growth in vehicle deliveries recently and its production capacity has increased throughout the year, despite global supply and logistics challenges related to the pandemic. Investors are likely expecting the company’s momentum to continue even as it faces these challenges.But nothing is in the bag yet.
