Artificial intelligence (AI) is rapidly reshaping finance, and stock selection is no different. AI models are increasingly used to identify undervalued and overvalued stocks, predicting future company performance.

This post examines AI for stock picking in more detail, considering current economic theory and potential consequences.

Current Economic Thinking

Current economic theory suggests stock prices reflect all available information about a company and its future. This means simply picking seemingly undervalued stocks isn’t a guaranteed path to outperforming the market passively.

However, AI proponents argue these models can identify patterns and trends invisible to humans. By analyzing vast datasets, AI models can pinpoint undervalued companies for reasons the market hasn’t considered.

Portfolio Return Optimization

A portfolio return optimization model could leverage AI to choose stocks that maximize expected return while considering risk. The model could incorporate various factors like stock price, company earnings, growth prospects, and beta risk.

The model could be adjusted monthly to reflect changing market conditions. This could help investors achieve the best possible return for their acceptable risk tolerance.

Stock Overvaluation Risk

One concern with AI for stock picking is potential stock overvaluation. If everyone uses the same AI model to pick stocks, they might buy the same ones, driving prices up artificially.

This could negatively impact the overall market, as overvalued stocks could be more susceptible to future corrections.

Competition Concerns

Another concern is that AI models could make it harder for individual investors to compete with institutional investors. Institutional investors have access to immense data and resources, giving them an advantage in developing and using AI models.

Individual investors might need to rely on financial advisors or AI-powered investment services to stay competitive.

The Final Word

AI models for stock picking are a powerful tool that can help investors improve portfolio returns. However, it’s crucial to be aware of these models’ limitations and potential risks.

Investors should use AI models to supplement their own analysis, not as a guaranteed path to success.
