But there's even more to this parallel.

Worth points out that in 1999, after Amazon's four-month bonanza, the company's market cap was $30 billion — which was one-fifth the market cap of Wal-Mart, the nation's biggest retailer. Today, Tesla has a market cap of $16 billion, which is nearly one-fifth of the $68 billion market cap that leading automaker Ford enjoys.

To Worth, that cements this similarities between Amazon in 1999 and Tesla today. "No one believed in that one (Amazon) and we know what's happened, and really, in a lot of ways, no one believes in this one (Tesla)."

That would also explain the speedy upward moves on the charts. "When something's brand new, no one's quite sure what it is, what it's worth, and where it's really going — because it's breaking molds. And that's what each of these stocks, in a way, is doing."

Michael Khouw of DASH Financial doesn't quite see it that way. "As much of a paradigm shift as Amazon represented for the brick-and-mortar stores, in this case you're dealing with four wheels, a steering wheel — you're dealing with a car. So a lot of people sell these things, and the only difference is the power plant," meaning the fact that Tesla's cars are powered by electricity rather than gasoline.

But Worth says the shocking similarities speak for themselves. "One can say 'Voodoo,' one can say 'Just coincidence,' but analogues are important," Worth maintained. And in an additional bonus for Tesla, "this one's got 40 percent of the float that's short."

So what does this all mean for Tesla shares?

Well, Amazon shares have risen three-fold from January 1999 to today. "Were Tesla to increase 300 percent from current levels," Worth notes, "we're looking at a $400 stock."
