The Ambarella Stock Price Is Up 86% – And We Have Another "Buy" Signal

The Ambarella stock price has climbed 81% in 2015, compared to a gain of just 1.1% for the Dow Jones Industrial Average in the same time.

And it climbed 1.2% higher afterhours today after another encouraging earnings report.

Ambarella stock is still one of the best plays in the tech market. Here's why we're still bullish…

Ambarella Stock's Newest Buy Signals

Ambarella is a video compression and processing-technology company. It is best known for developing the technology behind GoPro Inc.'s (Nasdaq: GPRO) wearable cameras. AMBA is a small-cap stock with a market cap of just $3 billion.

After the bell on Tuesday, the company reported earnings per share (EPS) of $0.71 on revenue of $71 million. Analysts had predicted EPS of $0.59 on revenue of $67.36 million.

Earnings were up 184%, while revenue climbed 73.5%.

Gross margins for the quarter were 64.7%, compared to 62.5% last year.

Today's report continued the company's strong earnings track record. In the previous four quarters, AMBA beat earnings estimates by an average of 29%.

On Monday, two investing firms raised their price targets on AMBA stock. Barrington reiterated its "Outperform" rating on Ambarella stock and raised its target 29% to $97. Finally, Pacific Crest raised its target 23% to $96.

AMBA opened Tuesday at $91.44. So hitting those price targets would be an additional gain of 5% and 6.1% from today's price.
