The 4 days to cover is a simplistic number based on taking the short # of shares divided by average daily volume of recent days. Soon, since the ADV is going down, # of days to cover will go up. It is meaningless. Some shorts are short from $30 and others from $190.
So you think bc it's the most shorted stock out there, with no earnings, a PE of 300 and was the biggest % gainer for the last 52 weeks, this is a screaming buy signal? All bc Elon Musk may say something positive about his company going through a public safety and marketing crisis?
Man, you can't trade with emotion and there is no way you can be that naive.
