After the trillion-dollar sell-off, bullish and bearish disagreements intensify: Goldman Sachs CEO remains bearish, former Barclays CEO says "healthy correction, not a bear market."

```

After a $1.6 trillion selloff in global stock markets, Wall Street’s top investment institutions are showing clear differences in their outlook. The Goldman Sachs CEO warns that the market may see further declines, while the former CEO of Barclays believes this is merely a healthy correction rather than a prelude to a bear market.

On Wednesday local time, Goldman Sachs President and COO John Waldron said in Singapore: "I think the market may pull back further from its current levels," and pointed out that technical indicators favor defensive actions and more room for declines.

In contrast, former Barclays CEO Bob Diamond is relatively optimistic about the market outlook. He said: "We're seeing risk assets being repriced. In my view, this is a healthy correction, not a sign of a turning bear market."

The S&P 500 has dropped more than 3% so far this month, on track for its worst monthly performance since March. Investors are closely watching Nvidia’s earnings, considered a key indicator of the sustainability of the AI boom and market stability.

Goldman Warns Technicals Are Bearish

Goldman Sachs President Waldron said in an interview that the current market technicals favor defensive stances and downside risk. He believes this year’s market has already seen considerable gains, and the current pullback "is healthy."

Waldron is paying special attention to the ROI of AI investments: "The market is now extremely focused on this AI dynamic: Will we get returns from the anticipated capital investment and is that already priced in? This is a major debate.” He expects any further market declines to be modest, “I do not think it will be materially more than what we’re seeing."

On credit market risks, Waldron specifically pointed out the vulnerability in the leveraged loan market and said underwriting standards have started to loosen, though this does not mean a credit crisis is imminent.

Former Barclays CEO: Healthy Correction, Not a Bear Market

Former Barclays CEO Bob Diamond took a relatively optimistic view of the current market turbulence on the same day: "We’re seeing risk assets being repriced, and in my view, this is a healthy correction, not a sign of turning towards a bear market."

Diamond thinks that investors are still groping to assess elements of technological change, which explains the recent global market volatility.

He remains confident about the long-term impact of AI: "I am reassured about the impact of AI over the next two to three, five years. I think it will play a truly positive role in curbing inflation and will also be very important for global economic productivity. Some people find current valuations confusing."

Algebris Warns Major Correction for AI Stocks

Davide Serra, founder and CEO of Algebris Investments, gave a more pessimistic warning at the forum. He advised investors to reduce their allocations to the world’s top tech companies: "It’s very likely we will face a major correction."

Serra’s pessimism is based on doubts about the revenue outlook from the AI revolution. He believes that “given the level of global public debt and the extent to which tax revenue needs to increase to match, it’s impossible to achieve income by 2030 sufficient to justify the rationale for the AI revolution.”

The veteran fund manager also pointed out that the U.S. market share is approaching mathematical limits: “Never in history have a third of economies accounted for 70% of global valuations. So we are peak territory."

Nvidia Earnings Will “Set the Tone” for Markets

All institutions are now focusing on the upcoming Nvidia earnings report.

Analysts believe Nvidia’s report will be a crucial moment for the market. Market strategist Ryan Grabinski said Nvidia’s results will likely cause a chain reaction in both U.S. and international markets. Despite somewhat cooling overall AI expectations in recent weeks, the report might turn sentiment back to optimism.

Currently, Wall Street’s fear index VIX has risen above 24, exceeding the critical 20 level that triggers trader concern and reaching its highest point in a month. Global markets are now balanced on the crucial question of whether AI spending can provide meaningful returns.
