For a while now, our friends at DealBreaker.com (and the banking expert Ray Soifer) have been telling us that the rate at which Harvard Business School graduates are taking jobs on Wall Street may be a contrary indicator of how the market will do. "When 10% or less of a graduating class take Wall Street jobs, it's a long-term buy signal," they explain. "When 30% or more take Wall Street jobs, it's a big flashing sell signal." How many Harvard MBAs took jobs on the Street this year? 44 percent. That's combined with an altogether decrease in the amount of work experience among the grads. Yipes! Not that we needed this indicator to tell us we're all fucked in the coming year. But at least it's nice that now we have such a deliciously scape-able goat.
