The person behind Ticker Nerd.

For most of my career, I’d have told you to buy an index fund. A Goldman trading floor shows you how much a private investor never sees — the flows, the positioning, who is on the other side of the trade. From there, beating the market looked close to impossible.

I still mostly believe it. For most people, a low-cost index fund is the right answer.

But one question kept pulling at me: why does a stock price actually rise? For years I had it backwards — I assumed you simply bought great companies.

The answer is expectations. Every price carries a forecast, and a stock rises only when the company beats it. A great company at a price that already assumes greatness goes nowhere — the return is the surprise.

Factor research is fifty years of published evidence on where those forecasts go wrong. Value, momentum, quality, revisions — measurable traits that have separated strong stocks from weak ones decade after decade, because the human errors behind them repeat.

That changed what I thought the game was. The information race is unwinnable from the outside; the factor game runs on numbers anyone can see. The edge it asks for is discipline — the one advantage a private investor can actually hold.

The evidence comes with costs attached — volatility, long stretches where the method lags, and holdings nobody has heard of. Those costs are probably why it keeps working; comfortable returns would have been competed away decades ago.

Ticker Nerd is that evidence run as a full-time job. One model rescoring roughly 4,600 US-listed stocks every day, one portfolio built by rules, every rule published — the framework I went looking for in fourteen years of markets, and my own money in the same book.

The temperament is deliberately boring: a fixed set of evidence, a fixed schedule, and rules deciding every trade. Excitement is the thing the method is built to remove.

The factors are visible, the trade ledger is visible, and every return we publish says whether it was traded or backtested — so you never have to take my word for it.

Ticker Nerd was founded in 2020 by Samuel Renotte and Luciano Viterale; I took it over in 2024 and rebuilt how the research is done. My name is on it, my money is in it, and I answer the email.
