Alphabet Inc. stock touched an all-time high on Tuesday morning after the Google parent beat Wall Street estimates on revenue and profit in the last three months of 2015. It was the first earnings report from the California tech giant to shed light on revenue and operating income from its so-called Other Bets, which include self-driving cars and smart home thermostats.

Alphabet’s stock opened Tuesday over 3 percent above its Monday closing price before the earnings were released, touching $804.50 before dropping back below $800. The company’s share price has gained about 49 percent over the past 12 months and is up about 2 percent since the start of the year, well above the S&P’s 5 percent drop in the same period of time.

The news sent Alphabet’s full market cap, which includes shares that are internally held, above Apple’s for the first time, though Apple still retains top status if you exclude internally held Alphabet shares.

Bowing to investor pressure, Alphabet reorganized last year to separate its core Google search, YouTube and Android businesses from its startup “moonshot” operations in transportation, healthcare and communications. “It shows that Alphabet remains focused on finding the next breakout idea, which will drive long-term growth,” said Tom Taulli, analyst for InvestorPlace.com.

Revenue from Alphabet’s core business rose 14 percent to $74.54 billion last year while operating income, excluding stock-based compensation, jumped 23 percent to $28 billion. Operating profit margin expanded to 38 percent from 35 percent.

Meanwhile, its “Other Bets” posted an operating loss of $3.1 billion, up from a loss of $1.4 billion in 2014. But revenue also increased to $448 million, from $327 million in 2014 and $12 million in 2013. These businesses include Nest home-automation, Fiber high-speed internet service and healthcare unit Verily.
