According to a financial analytics provider, Tesla's short interest is on the rise, and that's not good.
Data compiled by S3 Partners found that short interest for Tesla has risen almost 30-percent in two months, and currently sits at $11.4 billion.
But short interest is a measure of bets against a stock's success, and is not a measurement for a company's financial strength in a marketplace.
And for the last two years, Tesla's stock has been the premier short sale in the US equity market.
