the science of Momentum

---

The premier market anomaly is momentum. Stocks with low returns over the past year tend to have low returns for the next few months, and stocks with high past returns tend to have high future returns.

– Eugene F. Fama and Kenneth R. French 

Many said momentum shouldn’t exist. But the data told a different story. It shows up in stocks, bonds, and more. Across countries. Across centuries. We don’t fully know why. But we’re starting to learn.
