Reverse-ETF of whatever retail is buying
Aggregate the most-shilled tickers across retail channels and build the polite, boring opposite. Not advice. Obviously.
The premise: the crowd is not always wrong, but the loudest part of the crowd has a suspiciously good record of marking the top.
Aggregate the most-mentioned assets across retail channels the brain already monitors, weight by how frantic the language is, and construct the calm inverse.
The catch: timing. Being early is the same as being wrong, but with more time to feel bad about it.
Steal it — and when it works, remember it was free.
