Tesla jumps 10% as Musk's promise of 'more affordable' cars eases growth fears

The newly minted plans also helped shrug off the company's weak first-quarter results, including a lower-than-expected profit and the first drop in quarterly revenue in nearly four years.

"First impression for us is CEO is appeasing the market by accelerating new product launches," Jefferies analysts led by Philippe Houchois said in a note.

Tesla was on track to add around $50 billion to its market value of about $460 billion. The stock has slid 42% this year, as of last close, as high borrowing costs have dampened demand for EVs and a price war in major market China intensified.

Tesla's growth strategy could strengthen support for a shareholder vote in May on Musk's $56 billion compensation package, which was voided by a Delaware court in January.

Some Tesla investors - such as Ross Gerber, president and CEO at Gerber Kawasaki Wealth & Investment Management - had said in recent days that they planned to oppose the package, citing a decline in Tesla's share price and a compromised board.

'DE-CONTENTED MODEL Y/MODEL 3'

Several analysts took Tesla's remarks that its cheaper models would be built using current platforms and production lines as a sign it had retreated from more ambitious plans for an all-new model that had been expected to cost $25,000.

"We read 'more affordable' as potentially de-contented Model Y/Model 3 versions with improvements in software and AI/hardware capability, but at lower prices," Morgan Stanley analyst Adam Jonas said.

Musk declined to provide details of the more affordable models and instead spent much of the earnings call on Tesla's efforts to diversify its business into AI, humanoid robots and operating a fleet of autonomous vehicles - all based on software and hardware products it has not yet fully developed.

Investors and analysts have long given Tesla a premium valuation for its efforts such as its driver-assistance technology.

Tesla's stock trades at 57.38 times its 12-month forward estimated earnings, a PE ratio that is comfortably higher than Ford's 7.06 and General Motors' 4.80.

Tesla shares jumped to roughly $160 apiece, a price at which short sellers have lost $1.62 billion on paper since Tuesday's close, according to data and analytics firm Ortex.

However, short-sellers are still up almost $8 billion in profit this year.

At least nine analysts lowered their price targets on Tesla, while two raised. The median view now stands at $172.83, according to LSEG.

"While the details (on the new models) are thin on the ground, this was a clever move by Musk, as it justifies the negative cash flow and the higher capital spend," said Kathleen Brooks, research director at XTB.

"Unlike many companies that are shrinking capital spend in the current environment, Tesla is going against the grain ... and puts (it) in a strong position as the EV market gets more competitive and price sensitivity increases," Brooks added.
