It seems not that long ago that the air had been let out of Tesla Motors high-flying stock price. The company didn't adequately thrill the market when it disclosed its third-quarter 2013 financial results last November and TSLA price plummeted quickly enough to trigger a temporary halt to short sales. Immediately after that, the infamous Tenessee CarBQ happened, adding to the loss of altitude. Shares that had been, at one point, worth as much as $193.37 spent the last half of November 2013 bumbling along in the $120 neighborhood.

If you had chosen that low point to invest, we imagine you are wearing a very self-satisfied smile today. That's because the TSLA stock has more than reversed all previous losses and reached a high of $201.91. The most dramatic part of that rise came this week as the price saw a gain of $30. By the end of the day today, TSLA settled at $196.62, up just six cents from the close of trading yesterday.

Whether or not the stock has been buoyed by anticipation of the upcoming fourth-quarter financial reporting – estimated to happen a week from now – is hard to say. Certainly the fears over future battery supply constraints have been calmed, and we expect the upcoming call to have even more concrete details about the giga-factory. If you think you know the reason for the recent rise, please feel free to share with the rest of the class in the Comments.
