About
Led by MIT engineers and Wall Street analysts, Trefis helps you understand how a company's products, that you touch, read, or hear about everyday, impact its stock price. On Trefis you get answers to questions like: * What % of Apple's stock price is iPhones? (Q: Is it 5%, 25%, or 50%?) * What % of Dell's stock price is Dell Notebooks? (Fact: Most individual investors, or even a company's own executives, don't have a ball-park understanding of whether it is 15%, 45% or 75%)
