I’m a big fan of momentum, but I’m curious as to what your definition of momentum is?

I tend to think shorter term momentum in thematic names that often have some “cluster” effect to it, or herd effect is the most interesting, I also think there is momentum now attributed to market expectation adjustments and so forth, but I don’t think I’ve seen a good momentum definition, at least there are academic definitions but they never seem to account for mean reversions either. Curious on your thoughts as to what is good momentum vs bad?

I follow price with a few models; I'm not a big fan of definitions. Maybe academics are more interested in definitions, and that's a question for that space.

Agreed on the problem of the attractiveness of "narratives" to many, rather than a momentum-based approach. "Tell me a story" is fine but limited.
