Artificial intelligence is making big changes in how people trade stocks. This week brought news about AI systems picking investments and major AI companies reporting their results.

AI stock picking tools are becoming more popular with investors. These computer programs analyze market data and choose stocks they think will go up. For September, different AI systems picked various stocks including Eli Lilly, GE Vernova, and Nvidia. The AI tools noticed that money is moving away from expensive tech stocks toward safer investments like utility and healthcare companies.

The AI programs had mixed success in August. U.S. Bancorp and Barclays, picked by one AI system called Danelfin, did well with gains of 22% and 2.77%. But other picks like Nvidia only gained 0.26%, which was less than the overall market. GE Vernova and Vistra Corp actually lost money.

Big AI companies saw different results this week. Alphabet, which owns Google, had its stock jump 8% after a court decision. A judge ruled that Alphabet does not have to sell its Chrome web browser. This was good news because Chrome helps Alphabet's AI business. The company made $96 billion in revenue during the first half of 2025, growing 14% from last year.

Alphabet's AI business has been getting more attention lately. Even though some people thought Google was behind in the AI race, the company has been using AI since 2001. The stock has gone up almost 60% since April. Alphabet also has the lowest price compared to earnings among the biggest tech companies.

Nvidia shared news about its AI chip business and gaming division. The company that makes chips for AI training reported strong earnings. Jensen Huang, Nvidia's CEO, said AI is also helping improve video games. The company had a record quarter for gaming between its GeForce chips and Nintendo Switch. This shows how AI can help different parts of a business grow.

Oracle is another company getting attention from AI investors. Experts predict Oracle stock will do very well in September. The company provides cloud computing services that help train AI models. Oracle will announce its earnings on September 9th, and analysts expect good results. The company's order book is full, which means lots of customers want to buy its services.

However, not all news about AI was positive. Some warning signs appeared that worried investors. Sam Altman, the CEO of OpenAI, said that AI might be in a bubble. This means AI companies might be worth too much money compared to what they actually do.

A study from MIT also raised concerns about AI projects at companies. The research said that 95% of AI pilot programs at corporations are failing. Only 5% of these AI projects helped companies make more money quickly. This news made some investors nervous about AI stocks.

Market rotation is happening as investors move money around. Instead of buying expensive tech stocks, people are choosing safer investments. Healthcare stocks have done well lately, gaining 2.23% over the past month. Utility companies are also getting more attention from investors.

The AI trading systems noticed this change and started picking different types of stocks. This shows how AI can adapt to market conditions and help investors adjust their strategies. As more people use AI for trading decisions, these tools will likely become even more important in the stock market.
