Alternative data: Twitter case study

Twitter shares finished Friday 20% down at market close after reporting a decline in monthly active users during the second quarter.

The trouble here isn’t revenue (it beat estimates) or earnings (it hit its number). Instead, it’s about a decline in “monthly active users,” a figure that was depressed for reasons like new privacy rules in Europe, a purging of fake/abusive accounts, and not moving to paid SMS carrier relationships

This event was well known before the 2Q financial report
