Ehh... nobody can really set the tone. Most analysts don't know jack. What a lot of analysts do is look at comparables. What can you compare Tesla to? The answer is pretty much nothing. There's no company that does what it does. You can only bank on growth and expected growth - and earnings means nothing at this early stage in Tesla's development.
I would also not make any claim that Tesla's recent product rollout has failed - or use its stock price as a proxy for that decision. The near-term effect of $30 oil is quite impactful on many industries in many ways which we still have yet to fully comprehend. It could be that $30 oil is Tesla's undoing, simply because people don't need electric cars. We just don't know yet.
"On Monday, Morgan Stanley analyst Adam Jonas slashed his target price on Tesla stock to 333 from 450, reports noted, citing concerns about extra costs tied to the Model X launch delay."
