Tesla is undervalued (as of 2016-12-14)
Within 10 years, most new cars sold will be electric.
Tesla is currently the market leader in electric cars sold.
As the market for electric cars grows, Tesla is likely to be able to maintain a large share of the market.
Tesla’s current valuation implies a lower chance of success than is reasonable.
I’d update toward this position if I saw a good reason to expect you’ve gotten it more right than others.
