There are a lot of worrying signs out there right now, but one thing that has bolstered optimism is the strength of the stock market in 2019. That said, there are signs appearing that underlying fundamentals are weakening. In particular, daily moves are shrinking, down from 0.9% in the 4 months leading to February, to just 0.4% in February. The slowdown in trading momentum is not only worrying in its own right, but also because the exact same trend appeared before the falls of February and December 2018.
FINSUM: Our counter argument is that average index moves were quite small through several solid years between 2014 and 2018, so it dos not necessarily indicate a problem.
