Assessing Ambarella (AMBA) Valuation Following Recent Share Price Momentum

Ambarella (AMBA) shares climbed nearly 5% in the last trading session, catching attention as investors responded to fresh momentum in the stock. Performance over the past month remains under pressure. However, recent gains are drawing renewed interest in its valuation.

See our latest analysis for Ambarella.

Even with the recent jump to $83.45 per share, Ambarella’s 1-year total shareholder return stands at an impressive 45.61%. This easily outpaces the broad market and suggests momentum is picking up after a patchy stretch earlier this year. Gains over the past 90 days have helped revive sentiment, and investors are starting to reconsider Ambarella's valuation in light of its stronger long-term track record.

With Ambarella’s shares rebounding and long-term returns far outpacing the market, the key question now is whether there is still value to unlock in the stock or if the market has already priced in all future growth.

Most Popular Narrative: 11% Undervalued

Ambarella's fair value, according to the most widely followed narrative, stands at $93.73 compared to the last close of $83.45. This assessment points to untapped upside as a result of several powerful structural drivers and bullish analyst upgrades.

Sharply increasing demand for AI-powered edge devices including portable video, robotics (notably aerial drones), and edge infrastructure has led to a rapid expansion of Ambarella's addressable markets. This is evidenced by record edge AI revenue and multiple recent, diversified design wins. The trend is catalyzing strong, sustained revenue growth and positions Ambarella to benefit further as additional vertical applications for edge AI proliferate.

Another View: Price Tag Risks Loom Large

While analyst narratives suggest Ambarella is undervalued, a look at its price-to-sales ratio tells a different story. The stock trades at 10.2 times sales, which is double the US semiconductor industry average of 5.1 and well above its fair ratio of 5.6. This premium could add valuation risk, especially if growth expectations slip. Could enthusiasm be stretching the price too far beyond fundamentals?
