The main reason the stock does so well is that there are only a small percentage that are available to be traded. The Tesla owners and boosters own the lions share of that percentage. When Elon Musk personally bought $10M worth of stock this year from the open market, it created tremendous upward pressure.
Using non-GAAP accounting isn't going to win the hearts of analysts, but it will allow them cover for fan boys. The most recent issue is cash flow, something that sunk the price of GE stock, even though GE BEAT earnings per share. Tesla is requesting retroactive discounts from suppliers and NET 60 or longer terms.
