Why is Ambarella (AMBA) Stock Trending Overnight?

Ambarella Inc. (NASDAQ: AMBA ) shares are trending on Wednesday.

Shares of the California-based fabless semiconductor company surged 3.54% to $88.84 in the after-hours session.

The stock extended its 28.04% intraday gain, closing at $85.80, according to Pro data.

Wall Street Names AMBA Top Pick The rally followed a bullish note from Rosenblatt Securities analyst Kevin Cassidy, who named Ambarella his top pick on Tuesday for the second half of 2026, Investor’s Business Daily reported.

Cassidy issued a buy rating with a $120 price target, calling the chipmaker a “physical AI pure play.” He said demand for low-power AI vision processors used in surveillance cameras, autonomous vehicles, drones and robotics positions Ambarella for growth.

Cassidy added that the stock’s pullback since its May 28 earnings report offers a “buying opportunity.” In late May, Ambarella reported first-quarter results that topped analyst expectations on both earnings per share and revenue.

EPS came in at $0.11, far exceeding the consensus forecast of $0.01, while revenue of $100.36 million edged past projections by 0.20%.

Cassidy, in his Rosenblatt note published after the May results, raised the firm’s price target on Ambarella to $120 from $115 and kept a buy rating on the shares.

The firm said rising demand for AI models at the network edge is driving demand for Ambarella’s computer vision system-on-chip platforms.
