Some strategists say that slumping shares of Tesla could be in for even deeper losses, as the auto maker faces big tests of investor sentiment and its business strategy.
Tesla stock ended its worst weekly run in about a year and a half, dropping over 13 percent this week and briefly dipping into a bear market. The automaker faced down a litany of bad news, including delivery numbers that missed expectations, a set of bearish forecasts, and poor results in a vehicle safety test.
On Friday, the stock managed to pare some of its weekly losses, rising 1 percent to trade above $313 after the company reported in-transit vehicle figures that cheered investors.
From a technical perspective, the stock is hovering roughly $10 to $20 above critical levels, said Oppenheimer head of technical analysis Ari Wald. The stock rocketed from a little over $216 in the beginning of the year to an all-time high near $387 in late June.
With the stock falling 20 percent from those highs, Tesla has entered what some would term a "technical bear market."
Tesla's ability to supply cars is key, as the company has "never had a problem with demand," said Boris Schlossberg, managing director for foreign exchange strategy at BK Asset Management.
"The key question is, are they going to be able to ramp up supply? That is a big Achilles heel, because they have always come up short. So they're really going to have to step up next year," Schlossberg told CNBC's "Power Lunch" this week.
If the automaker can achieve deliveries in the ballpark of 200,000 units, he said, the stock could bounce back. On the other hand, if it continues to "disappoint with supply, that's when you get into trouble and I think the stock could really sell off hard."
