Seems to me that some of the TSLA pain is self inflicted. Musk is the largest stock holder and is passionate about his company. He also has an intense dislike for the Short Sellers. I believe that clouds his focus. He has resisted issuing new stock, partly to not dilute his personal holdings, but also out of principal to avoid giving the Short Sellers any ammunition that TSLA's financial picture and future growth aren't as strong as he projects.
For example, when the stock soared above $350 earlier in the year and optimism about the company was high, Musk decided not to issue new stock. This seems like a mistake that a more seasoned CEO wouldn't make. He had an aggressive agenda at the time - Expand into China, introduce several new cars - Model Y, Truck, Roadster (New revenue sources) - enhance and expand the SuperCharger Network (needed to keep new Tesla owners happy with increased charging demand) - and support better customer service and possibly begin to advertise - reinforcing the positive TSLA narrative and expanding demand. All of this is incredibly capital intensive. He could have issued a secondary stock offering of $2+B (about 6 million shares) and taken advantage of the high stock price to replenish the Balance Sheet, reduce debt, fund many capital intense projects. This was especially critical since there was a convertible debt offering coming due shortly that required the stock to remain at lofty levels to avoid a big cash payment. If the stock stayed high, the extra shares wouldn't have been much dilution. If the shares fell, as they did, the $2B cash infusion would offset part of the $950M debt payment. Either way, TSLA would have benefitted. It was a low risk strategy at the time, giving TSLA lots of flexibility at minimal risk.
Now, if cash flow remains low from reduced sales, balancing sales to China, etc., Musk may have to sell stock anyway, and at prices 30% lower than they were in January. This, to me, is one of Musk's shortcomings - his passion may sometimes cloud his financial judgment, and blind him to the financial arguments made by his senior management team. That may be why the new CFO resigned quickly - he saw the issues clearly and likely wasn't able to get Musk to set aside his emotions and make the hard business call.
I'm still a fan, and owner, but I'm also realistic about the differences between Wall Street's financial demands for any company and those of a founder. TSLA is a "Story Stock", run by a passionate leader. That can work (look at AMZN), but for it to work there has to be consistency and a clear vision that is achievable. Bezos lost money for years, but he kept to his plan - aggressively disrupt traditional businesses and build for the future. TSLA has the same concept, but the clarity of the vision, the ability to "stay on script", and showing continuing progress and financial consistency seems lacking.
This situation is further complicated by the liabilities TSLA assumed when it bought SolarCity, which are significant and haven't been discussed very much lately. If you read TSLA's SEC filings carefully you may be surprised by the risks TSLA assumed through the SolarCity buyout. I would expect Short Sellers to begin to resurrect the financial implications of SolarCity's potential cash drain on TSLA as they press their negative FUD bet.
Finally, whether the SEC "wins" and has an impact on Musk's position at TSLA or not, there seems very little upside in having another distraction, especially one with potentially significant impact on the company. For TSLA to reach the same trajectory and success, it may be time for TSLA's Board of Directors to do more than cheerlead and get a suitable team around Musk to reach the next level.
Is the world ending for TSLA? Clearly not, but the transition from "Story Stock" to "Real Company" demands more consistency and focus, and a skillful team dedicated to doing just that. Bezos has that focus alongside his passion, and Tesla needs the same. The quicker this happens the better for all involved, IMHO. Facebook had a similar problem, and the answer was to reshuffle management, bring in some talent where needed, and move forward. TSLA is more like Facebook than AMZN in many ways, I believe, and the remedy may be a similar refocus and team buildout.
