In November 2022, the bank predicted losses of $1.6 billion for the fourth quarter. It was made after the announcement of a number of measures to eliminate unsatisfactory work of its investment unit, as well as the elimination of a number of risks, which led to such consequences. It also emerged at the time that the bank continued to experience significant net asset outflows.

"The outflows, as we said, have reduced very significantly, and we are seeing now money coming back in different parts of the firm," Koerner said on the sidelines of the World Economic Forum in Davos, Switzerland.

Notably, as part of the "overhaul," Credit Suisse shareholders approved a $4.2 billion capital raising last November, including a new private placement that made the National Bank of Saudi Arabia the largest shareholder with a 9.9% stake.

"We laid out a very clear plan, and we talked to all different stakeholder groups in the last three months, as you would expect. I think the plan, the strategy resonates very much. We are in full execution swing, so I think we are making really good progress," Koerner said. He also added that Credit Suisse had also reached out to tens of thousands of clients in Switzerland and around the world for feedback.

Premarket

United Airlines' stock rose by 3.5% after the company reported quarterly earnings that beat Wall Street estimates. The airline signaled strong demand for services even amid higher prices. United posted adjusted earnings per share of $2.46 on revenue of $12.4 billion. Analysts had expected earnings per share of $2.10 and revenue of $12.2 billion.

Moderna's stock increased by 7.5% after the drug company said on Tuesday that its RSV vaccine for older adults is 84% more effective than before. Clinical trials also showed no safety problems with the vaccine.

IBM shares fell by about 2% during premarket trading after Morgan Stanley downgraded the stock to "hold" from "buy," citing concerns about slowing earnings growth.

JB Hunt Transport Services, a transportation company, lost more than 1% after fourth-quarter results fell short of analysts' expectations. Analysts had expected earnings of $2.44 per share on revenue of $3.81 billion, when in fact earnings were $1.92 billion and revenue of $3.65 billion.

As for the S&P 500 index, it has not changed much. The index may continue to grow but it is necessary to protect the level of $3,980, which will be the priority for today. Only after that, it is possible to expect a more confident upward spurt which may send the trading instrument to $4,020. However, ot would be difficult to pierce $4,038. If the price declines and there are no support levels at 3,980 and $3,960, bulls will have to protect $3,920. If this level is broken through, the trading instrument may be pushed to $3,866 and $3,839.
