According to the Futu Financial App, facing the positive interest rate hike of the Federal Reserve, Wall Street has been confused about the sustained resilience of the US economy, and some people insist that the US economy will soon face a recession. But Steve Eisman, senior investment portfolio manager at Neuberger Berman, is bullish on the financial market, saying that "the critics of the US economy are wrong" due to the competition of artificial intelligence and the promotion of infrastructure projects.

He said in an interview last Thursday,"We are just gaining momentum, and I think the only conclusion we can draw is that the US economy is more vibrant than ever before."

In "The Big Short", Eisman portrayed the bet against toxic mortgages that led to the financial crisis. He added that the next phase of the tech narrative will be the purchase of new artificial intelligence smartphones and laptops by consumers. He predicts that this means that Apple (AAPL.US), which has just released a series of new AI features, will usher in a large-scale user upgrade cycle for the iPhone.

Eisman added that his company has started to study other potential symbols that benefit from the trend of artificial intelligence, but he also insists that investors should hold onto Apple, "holding your Apple position strongly, as it is too central to the whole story."

Microsoft (MSFT.US) and Google's parent company Alphabet (GOOGL.US) are both developing artificial intelligence technology and are also "core holdings". However, Eisman also proposed an interesting hypothetical question: if artificial intelligence is as successful as expected, the cost of creating software will "implode", which means that the competitive advantages of some companies will no longer be unbreakable.

He added, "Therefore, you can say that the value of hardware will continue to be re-evaluated, but some parts of software will weaken." In other words, technology hardware companies that supply to the artificial intelligence field are likely to continue to thrive, but software stocks may not.

The sharp rebound of Nvidia (NVDA.US) is an example of the recent shift in hardware stocks. So far, the stock price of this leading artificial intelligence chip company has soared 166% this year, more than 200% compared to the same period last year, becoming a company with a market value of 3 trillion US dollars, and accounting for more than one-third of the rise in the S&P 500 index this year.

Nvidia's quarterly report shows no signs that the frenzy of hoarding artificial intelligence chips will slow down. However, it is worth noting that Torsten Sløk, chief economist at Apollo, also warned that such reliance on a single stock represents huge risks.

In a note on Wednesday, he wrote:"Such a high concentration means that if Nvidia continues to rise, everything will be fine, but if it starts to fall, the S&P 500 index will be hit hard."
