Update: *TWTR'S NOTO: THIS IS BOTH A PRODUCT ISSUE AND A MARKETING ISSUE, DOESNT SEE SUSTAINED GROWTH IN MAUS UNTIL REACH MASS MKT
Just like on previous quarters, TWTR decided to use a gimmick when counting users, to wit: "Average Monthly Active Users (MAUs) were 316 million for the second quarter, up 15% year-over-year, and compared to 308 million in the previous quarter. The vast majority of MAUs added in the quarter on a sequential basis came from SMS Fast Followers. Excluding SMS Fast Followers, MAUs were 304 million for the second quarter, up 12% year-over-year, and compared to 302 million in the previous quarter." It took algos a few minutes to digest this fact, and as a result what was initially a solid 10% spike after hours, fizzled almost entirely, and as of this moment the stock had cut its after hours gains notably.
