So far, fear has driven investors to sell consumer-exposed stocks. A basket of such companies — including Oreo cookies maker Mondelez International Inc. and Modelo beer producer Constellation Brand Inc. — is down nearly 9% since early August with losses roughly double those of the S&P 500 Index, while makers of things like insulin pumps have wiped out close to a third of their value over the same stretch amid concerns that fewer people will need their products.
How prolific is a diet pill if it has brought down sales by 9%? Or are these relatively few people really having that much of an impact?
