Macron's Davos sunglasses dominate social media, Italian manufacturer's official website crashes, stock price skyrockets.

When French President Macron walked onto the Davos stage wearing a pair of reflective blue aviator sunglasses, iVision Tech SpA CEO Stefano Fulchir couldn't help but take a second look. This little-known eyewear manufacturer based in a small town in northeastern Italy had a market value of only about 12 million euros before the French president's appearance. But the entrance of this French leader made its eyewear products the global focus, causing its stock price to soar, with an increase of over 60% in three trading days, pushing its market value to 19 million euros. "After Macron's speech at Davos, our website crashed due to the overwhelming number of orders," Fulchir said in an interview.
