Eager stock market analysts have been quick to pour over the latest Q4 2015 SEC filings from Alphabet, Google's parent company. The market responded quickly with both the Class A and Class C stock trading up to a $750-780 price range. This makes Alphabet not just good at letters, but also with numbers as it now eclipses Apple's market capitalisation to be the most valuable company in the world.

In fairness, Apple's earnings were showing signs of hitting a plateau with its iPads not selling as many units as they once did as interest moves more to the phablet-size phone market and away from larger tablets which are less convenient on the run. Investors in Alphabet were quick to double down on their positions and others buying into Alphabet for the first time on the positive trading news.

Alphabet revenues year-over-year rose 24% compared to 12% the previous year. The source of the accelerated revenue growth has been primarily from advertising. The picture is a mixed one through with ad clicks rising by 31%, but the cost per click for adverts falling by 13%. Overall, Alphabet still came out ahead.

The company also noted on a recent call with investors that Gmail, its email service, now has more than 1 billion active users each month. That's active users, not open accounts. Only What's App and Facebook can say the same.
