Whether the CFO leaving is a "canary" or not, I think there is ample evidence that Tesla's overall value proposition is grossly misaligned with its current valuation (futures priced-in). I would not blame people for using this as an excuse to weaken their positions on Tesla. I am invested and have been for almost a decade, for the record.
Obviously the odds of this happening are close to 0 but after investing heavily in Tesla I came to the conclusion (perhaps wrongly) that a good deal of the value in tesla stock is tied to Musk. He could get hit by a bus tomorrow.
So I sold and put it all in an index fund that still holds tesla but on a more diluted basis.
Just curious about your outlook on it.
