A more realistic price to earnings multiple is closer to 100. Beyond 2015, Tesla should be able to achieve better results. Many, including myself, have faith in CEO Elon Musk's ability and skills to expand this company. It's not lost upon me that electric cars have a future, but it's imperative that valuations remain in context.

Tesla's market share is less than 1% of Toyota's (TM). Toyota is profitable. Toyota's market capitalization is only eight times larger.

Tesla's revenue is less than 2% of Ford and GM, and yet the Tesla's market cap is nearly half of the other two. If Tesla's top and bottom line growth was 50% year-over-year, a valid argument could be made that supports a $200 per share valuation.

Tesla can't get there right now because of supply-chain constraints, and even if it that were not an issue, the company isn't selling cars at a profit.

I know that is expected to change, and a Texas-sized battery factory is in the works. By the time it's up and rolling, however, the market will change, or at a minimum, investors should anticipate changes.

Changes may include GM, Ford, Toyota and others effectively encroaching further into the electric car and alternative fuel sector. Tesla isn't only facing competition from other electric vehicles; other fuels such as natural gas can disrupt growth.

The point is the further out in time one must allow Tesla to grow into its current valuation, the greater the perilous game-changing shifts in the market will disrupt the bull thesis. Just don't confuse my bear thesis on the stock with a bear thesis for the company.

The company is fine - it's shareholders with a cost basis above $200 who may have a problem.

Coming to their rescue and saving shareholders are short sellers. Short sellers buying back shares are holding the price from total unmitigated collapse today. When a heavily shorted stock is falling fast, short sellers are willing to step up and bid to cover when others fear the falling knife.

With over 25% of shares shorted, the safety net is wide, but in the long run, it won't stop Tesla's valuation from reaching a true equilibrium. If you want to own this stock, wait until it's under $100 and scale in slowly. Better yet, sell $100 puts that you won't mind having exercised so you can collect option premium.
