Overview:
Alphabet shares fell 11.6 percent on disappointing quarterly results, wiping 437 billion dollars from the technology giant's market capitalization. The decline reflects investor concern that massive artificial intelligence spending may not generate sufficient returns to justify its cost. Saudi Arabia's Capital Market Authority issued new regulations governing algorithmic trading, while Egypt's central bank raised benchmark interest rates by one percentage point to combat currency pressures and inflation.
Details:
Alphabet shares tracked toward their largest single-day loss on record following earnings that fell below analyst forecasts. The stock had declined as much as 13.7 percent earlier in the session before closing down 11.6 percent. The selloff erases the company's previous largest market-value loss of approximately 275 billion dollars, reflecting deep uncertainty among investors about the return on capital from artificial intelligence infrastructure investment.
The Saudi Capital Market Authority required all financial institutions to comply with new restrictions on algorithmic trading effective November 1, 2026, with a correction period through December 31, 2026. Registered traders are limited to a maximum of twenty algorithmic trading orders per day per security in the primary market during open sessions, classified by liquidity level. The regulator mandated institutions implement effective monitoring systems and provide required data to exchange authorities.
Egypt's Central Bank Monetary Policy Committee raised the overnight deposit and lending rates to twenty and twenty-one percent respectively, and increased the main operation rate to 20.5 percent. The decision responds to currency market pressure, with the dollar trading above 56.35 Egyptian pounds against the central bank's bid rate. The moves address inflation concerns and foreign investment volatility.
Outlook:
Technology investors will monitor whether Alphabet management can articulate a clearer strategy for artificial intelligence monetization to arrest the selloff. Arab central banks face competing pressures between controlling inflation and maintaining attractive returns for foreign capital inflows amid regional geopolitical tension and oil price volatility.
