The stock market has its moods, but sometimes, it is mostly its fears. And this Friday, fear prevailed over everything else. An Israeli strike against Iran was enough to cause an immediate shock on global markets, reminding everyone that indices are never completely disconnected from the sound of bombs. In New York, the Dow Jones dropped more than 600 points right at the opening. A brutal collapse that owes nothing to chance, but everything to geopolitics. In this unstable equation, volatility has become the norm again, and the stock market a sounding board for the real world.
