Back in July 2008, just before all hell broke loose and the S&P was trading in the upper 1,200s, everyone's favorite permabull, JPM strategist famously reiterated his S&P 500 price target for the end of 2008: 1450. Two months later Lehman filed for bankruptcy, and 4 months later the S&P closed 2008 some 40% lower than said price target. Another two months later and anyone who had listened to Tom Lee lost 50% of their investment. Today, as the Fed's balance sheet crosses $3 trillion, and the global central banks have pumped a total of some $15 trillion into the markets, Tom Lee ws back on CNBC with what is his most permabullish prediction ever: he now expects the S&P to generate some 150 in earnings to which he applies a 17x multiple. His conclusion "If you put a 17 multiple on $150, the S&P really sort of peaks around 2,400 or 2,500." In Dow terms, this means a Dow Jones Industrial Average of, drumroll, 20000. He does, caveat it, however: "that's obviously 4 years away." And if Tom Lee was off by 40% in 4 months, we can't help but wonder what the hit rate on his 4 year prediction will be, and if, by using the same ruler extrapolation mechanism he applies to corporate earnings nand multiples one extrapolates the Fed's balance sheet at some $7 trillion in 4 years, what a loaf of bread will cost just as the DJIA crosses 20,000.
