Why AMBA stock is up today

Ambarella Inc. (AMBA) surged 8.38% to $68.80 in morning trading on Tuesday. The move followed the release of a transcript from the company’s Q2 2027 earnings call, which highlighted record edge AI revenue and a $22.9 billion serviceable addressable market (SAM) forecast. The transcript provided a growth-oriented outlook that appears to have driven the sharp intraday rally.

What Happened

The stock opened at $63.64 and quickly found support, rising to a session high of $71.24 at 10:00 AM ET. The upward momentum followed the publication of the earnings call transcript by The Motley Fool, which detailed Ambarella’s progress in edge AI and its expanded market opportunity. The transcript emphasized the company’s strategic positioning and potential for future growth. Meanwhile, several analysts have recently adjusted their price targets for Ambarella, including Roth Capital lowering its target to $65, Stifel to $90, and B of A Securities to $70, all while maintaining or adopting neutral or buy ratings.

What The Data Shows

Ambarella’s fundamentals remain mixed. The stock has a market cap of $2.8 billion and is unprofitable with an EPS of -1.30 over the trailing twelve months. Revenue, however, grew 20.0% TTM. The stock has traded between $48.30 and $96.69 over the past 52 weeks. Trading volume has spiked to 4.0 million shares, or 2.5 times the 3-month daily average.
