How much is Google-parent Alphabet Inc spending on “moonshots” – self-driving cars, glucose-monitoring contact lenses, Internet balloons and other ambitious projects?

Investors will get their long-awaited answer when Alphabet reports fourth-quarter results after markets close on Monday.

The report will be the first time Alphabet will break out results for what it calls “Other Bets,” which includes Google Fiber; smart home accessory maker Nest Labs and the secretive “X”, home to the self-driving cars project.

The results will also show how successful Google was in targeting ads at a fast-growing number of mobile users, especially after Facebook Inc’s (FB.O) stellar report.

A strong report could boost the stock enough for Alphabet to surpass Apple Inc (AAPL.O) as the most valuable company in the world.

“For the first time they (Alphabet) have a real catalyst to the stock, aside from a standard beat-and-raise,” said James Cakmak, an analyst at Monness, Crespi, Hardt & Co Inc.
