Investor Says He 'Doubled' His Savings After Using ChatGPT in Stock Research – Shares Top 5 Stock Picks

Retail investors are increasingly using AI models and chatbots to find winning trades and beat the market. The use of AI tools to build stock portfolios has increased 46% year over year among retail investors, according to a survey by broker eToro Group Ltd. (NASDAQ:ETOR) released in October.

In September, an investor on Reddit said he used ChatGPT for stock research and built a portfolio that delivered strong returns over a period of three months.

"I asked it to do a deep dive on 5 penny stocks that are most likely to return 10x value over the next 7-10 years," the Redditor said. "On average, across these five stocks, I doubled some of my savings in three months."
