Musk said growth would be "notably lower" as Tesla focuses on a cheaper, next-generation electric vehicle to be made at its Texas factory in the second half of 2025, which is expected to spark the next boom in deliveries.
But his remarks fell flat with investors, with Tesla set to lose about $70 billion in market value, if losses hold. That would push its market capitalization loss for the month to about $200 billion.
"The Tesla headlines have essentially gone from bad to worse," said TD Cowen analysts, noting that the fourth-quarter revenue and profit were also below expectations.
Shares of other EV makers also fell, with Rivian Automotive Inc (RIVN.O), Lucid Group (LCID.O) and Fisker (FSR.N) down between 4.7% and 8.8%.
The EV industry has been grappling with a slowdown in demand for more than a year and the price cuts by Tesla will likely worsen the pressure on the startups and automakers such as Ford (F.N).
"The problem for Tesla is any significant attempt to boost sales from here on will probably need to be achieved at the cost of further falls in operating margin, due to having to compete with BYD in China, as well as increased competition elsewhere," said Michael Hewson, chief market analyst at CMC Markets.
At least, nine brokerages downgraded the stock, while seven raised their ratings. The company, on average, has a "hold" rating with a median price target of $225, nearly 9% higher than the share's last closing price.
Tesla short sellers have made $3.45 billion so far this year, making it the most profitable U.S. short trade, according to data and analytics firm Ortex.
The company's stock trades at nearly 60 times its 12-month forward earnings estimates, according to LSEG data. That gives it a more premium valuation than the other "Magnificent Seven" stocks – a group that includes Apple, Microsoft and Nvidia.
Some analysts said valuation could become tough to justify if Tesla's sales growth and margin weaken further.
"Tesla is increasingly looking like a traditional auto company," said Bernstein analyst Toni Sacconaghi.
