Apple loses $450 billion in value since record on iPhone woes

When talking about the biggest company in the world, it’s not unusual for there to be eye-popping numbers. But Apple Inc.’s latest superlative is not one investors would like to see.

Since becoming the first American company to surpass $2 trillion in market value in August and peaking last month, the iPhone maker has lost $450 billion, wiped out by a 19% slump. The latest bout of selling — a 5.6% drop on Friday — took out more than $120 billion alone. Apple’s now worth $1.85 trillion and still the most valuable U.S. company, but the amount shaved from its ledger since its September peak is more than the entire market cap of Visa Inc., the seventh largest member of the S&P 500, and greater than the value of Thailand’s stock exchange.
