The two most expensive emotions you can have as a human are "anger and pride," according to Money Morning's Quantitative Trading Specialist, Chris Johnson.
And if you have them both at the same time, it can be very destructive to your portfolio.
That's how Chris is thinking about Tesla Inc. (NASDAQ: TSLA) right now as the number of short positions has never been higher on the stock.
It's clear these short sellers have a ton of pride, continuing to bet against one of the hottest momentum stocks on the market (Tesla is up 254% year to date),
And they're surely feeling angry losing money day in and day out to a company that sells a fraction of the cars as the major carmakers, but is currently the most valuable electric vehicle stock in world (with its $280 billion market cap).
So, what should investors do?... Is it too late to buy TSLA stock or should you continue riding this momentum higher?
