Another tech giant in focus at the start of the week was Alphabet (GOOG), after the European Union’s top antitrust enforcer reportedly said that a decision is coming on whether Google is breaking the bloc’s new digital competition law.
The Wall Street Journal reported on Monday that EU competition commissioner Teresa Ribera said that a decision was in the making, ahead of her meetings with the CEOs of major tech companies in the US this week.

“It will come,” Ribera told Dow Jones Newswires. “These are complicated cases, and I think that it is important for us to honor our sincere commitment to take decisions based on evidence, and to be fair in the respect of the rights of procedure.”
Shares in Google-parent Alphabet (GOOG) dipped 1.3% in pre-market trading on Monday and are currently trading nearly 5% in the red year-to-date.
Shares in chip design software company Synopsys (SNPS) rose nearly 3% in pre-market trading on Monday, following reports that activist investor Elliott Investment Management had built a multibillion-dollar stake in the business.
According to a Bloomberg report, Elliott managing partner Jessie Cohn said that Synopsys is “essential” to the global chip industry.
Synopsys (SNPS) and Elliott Investment Management had not responded to Yahoo Finance UK’s request for comment at the time of writing.
In London, Endeavour Mining (EDV.L) was the biggest faller on the FTSE 100 (^FTSE) on Monday morning, with shares in the gold miner falling 5% in early European trading.
The fall in shares came as gold prices slid on Monday, with futures (GC=F) tumbling nearly 7% to $4,256.80 per ounce at the time of writing.
Wealth Club chief investment strategist Susannah Streeter said that gold (GC=F) prices have experienced a “brutal drop” as the conflict between the US, Israel and Iran has escalated.

She said: “Gold is usually seen as a safe haven in times of severe conflict, but a collision of factors is pushing down demand. Essentially, the opportunity cost of holding gold is mounting.”
“As government bonds, in particular treasuries, see yields rise, it makes gold less attractive given that gold pays no interest,” she explained. “Investors who have made losses elsewhere in volatile markets are selling to cover positions, while the strengthening of the dollar also makes gold more expensive for buyers in other currencies.”
