3rd place$NVIDIA (NVDA.US)$It closed down 0.46% and sold US$9.317 billion.Michael Kagan, chief technology officer of Nvidia, pointed out that cryptocurrency miners have purchased a large amount of Nvidia hardware, yet cryptocurrencies will not bring anything useful to society. This is the reason why the crypto market has been rapidly collapsing recently.

In contrast, he favors artificial intelligence because artificial intelligence is beneficial to society. Artificial intelligence allows individuals to create customized programs to meet different needs. However, the high-frequency trading of cryptocurrencies actually has no meaning for humans.

As a result, he suggests that people use processor chips used for cryptocurrency mining to develop chatbots, such as ChatGPT, which can add more value to society.

17th$Occidental Petroleum (OXY.US)$The company closed 4.29% higher and traded $1.32 billion.Regulatory documents show that Berkshire Hathaway, a subsidiary of Buffett, bought 3.7 million shares of Occidental Petroleum and spent 216 million US dollars. The shareholding ratio increased to 23.6%. This is the third time this month that “stock god” has increased its position.

Buffett's company began buying large quantities of Occidental Petroleum's shares more than a year ago after the Russian-Ukrainian conflict caused oil prices to soar. This month, it has already spent more than 1 billion US dollars to buy the company's shares.

TD Cowen analyst David Deckelbaum raised Occidental Petroleum's rating from “in line with the market” to “outperforming the market,” and raised the target price from $63 to $70. The analyst said it provided a “superior” risk/benefit return given the impact of crude oil pricing capacity, changes in capital structure, Berkshire Hathaway's holdings increase, and good free cash returns. The analyst told investors in a research note that the company “provided a differentiated and rich catalyst in a relatively homogenized world” across the exploration and production sector.
