The Nasdaq index has fallen to its lowest point since September, with major tech stocks losing a staggering $2.7 trillion in market value over three weeks. This decline, driven by fears of a trade war following President Trump's tariff announcements, has hit the largest US tech firms hard, with Nvidia, Apple, and Microsoft experiencing the most significant losses. The Nasdaq is down 4.9% for the week, on track for its worst performance in six months, with Goldman Sachs labeling the sector the “Maleficent 7.”
