## Definition

An AI stock picker is software that uses machine learning or other statistical models to rank, score or suggest individual stocks to buy, sell or watch.

## AI stock picker, explained

Most AI stock pickers take in price history, fundamentals, analyst estimates and sometimes news or sentiment data, then output a ranked list of stocks, a score per stock or a set of trade ideas. The model behind the output is usually proprietary, so you see the result but not the full reasoning.

They differ a lot in time horizon. Some aim at holding periods of weeks or months, others suggest intraday trades. That matters more than the label "AI": a tool built for day trading is a poor fit for a long-term investor, and the other way round.

A pick is a probability estimate, not a guarantee. Before paying, check whether the vendor publishes a full, dated record of past picks against a benchmark such as the S&P 500, and whether that record includes the losers as well as the winners.

## Example

An AI stock picker might show a ranked list of 20 US stocks each morning, with the model's top-rated names first and a short note on which factors drove each rating.
