(Bloomberg) -- For all the stock market gyrations last week, one company’s performance stands out beyond all others: Tesla Inc.

Tesla’s stock has plunged 16% over the five sessions, marking its worst week since March 2020’s Covid-stricken market selloff. Meanwhile, the S&P 500 Index recorded its best week in a month, closing up 1.5% on the strength of powerful rallies last Monday and Tuesday. Tesla was by far the biggest weight on the S&P this week, knocking about 13 points off the index. 

The EV-maker’s issues are no secret. It has been battered by the one-two punch of disappointing quarterly deliveries and Chief Executive Officer Elon Musk’s surprise decision to revive his offer to buy social-media platform Twitter Inc. The Twitter deal comes with the possibility that Musk will be forced to sell Tesla shares to finance the deal. 

For ardent Tesla fans like ARK Investment Management’s Cathie Wood, the selloff offers a chance to buy more of the stock at its cheapest price in months. The growth-stock guru, whose funds have been hit hard this year amid soaring inflation and rising interest rates, snapped up shares worth about $32 million on Monday. Mom-and-pop traders were also big buyers, with nearly $540 million in net purchases over the past five trading days, Vanda Research said.

On the flipside, there are more cautious investors, who say the stock has several hurdles to navigate before finding a clear runway. A looming recession, growing threat of competition, a wary consumer squeezed by high inflation and the stock’s expensive valuation are the biggest worries. 

Musk’s Focus

“Will Tesla’s stock retain a halo effect and prosper while other high growth, high valuation stocks suffer? It hasn’t so far this year,” said Catherine Faddis, chief investment officer of Grace Capital. 

Musk’s purchase of Twitter adds a few more wrinkles. In addition to the uncertainty around the deal’s financing, investors are also worried that the billionaire could be pushing himself beyond his limits with so many demanding ventures.

“Musk will need to ‘justify’ the valuation he paid for Twitter by generating value as soon as possible, this will take his time and focus away from running Tesla,” said Brian Mulberry, client portfolio manager at Zacks Investment Management. “Musk may be a genius businessman, but he is still a human being and a day is still only 24 hours long.” Zacks owns Tesla stock through its All-Cap Core fund.

Meanwhile, even with this selloff, Tesla continues to tower over Big Tech and most of the S&P 500 with its eye-watering valuation. Tesla shares are trading at 40 times the company’s estimated forward earnings. By comparison, the S&P 500 trades at an average of 15 times, and Apple trades at 23 times.

All that being said, there is a reason why Tesla has such a lofty valuation. It’s about the future. Tesla’s dominating position in the still nascent and fast-growing EV market makes it dangerous to bet against, particularly in a global economy that will soon be powered by green energy. And Musk, for all the distractions pulling at him, is committed to making the company a success.

“Tesla is unique among US big tech right now because it has a much clearer fundamental growth trajectory than any other name. It also has the largest ‘key man’ risk of any stock in the S&P 500,” said Nicholas Colas, co-founder of DataTrek Research. “Musk’s attention to Tesla is worth a lot to many investors.”
