Marvell-Lumentum acquisition, Apple balance sheet and inflation data in focus
AI-generated summary
There are questions about the sustainability and revenue contribution of major investments in artificial intelligence. While inflation pressure continues in the USA, the Fed's monetary policy stance is remarkable. Efforts to reduce tensions in the Middle East and Russia-Ukraine negotiations are on the international agenda.
The election process in the USA, developments in the Middle East axis and continuing doubts about artificial intelligence spending continue to have an impact on asset prices. While investors question the sustainability of large investments made in the field of artificial intelligence, question marks remain regarding when these expenditures will contribute to the income and profitability of companies.
Accordingly, artificial intelligence and technology stocks came under selling pressure yesterday as company-based developments increased existing concerns.

Oracle's shares also lost 8.76 percent after the company announced that it plans to issue $10 billion in stocks and $10 billion in bonds to finance its artificial intelligence investments.

In this regard, the data on the labor market to be heard throughout the week, especially the non-farm employment data to be announced on Friday in the USA, and the verbal guidance of Fed Vice President Michelle Bowman are in the focus of investors.
Post-election Iran message from Trump
