Affiliated investment bankers are overly optimistic at IPO Michaely and Womack (1999): “Conflict of Interest and the Credibility of Underwriter Analyst Recommendations,” Review of Financial Studies Analysts are an important factor when companies pick bankers Krigman, Shaw, and Womack (2001): “Why Do Firms Switch Underwriters?” Journal of Financial Economics Analysts are optimistic to obtain access to management Lim (2001): “Rationality and Analysts’ Forecast Bias,” Journal of Finance Optimistic analysts are more likely to move to better firms Hong and Kubik (2003): “Analyzing the Analysts: Career Concerns and Biased Earnings Forecasts.” Journal of Finance

    4. 4 “Analysts, Industries, and Price Momentum” (Boni and Womack, 2003) Can analysts rank future winners and losers in their industry? Analysts are industry specialists. Proper test of stock-picking ability is an industry-based analysis. Analysts signal rankings with upgrades and downgrades. Examine self-financing portfolios (long net upgraded stocks, short net downgraded stocks). Dataset: U.S. stocks. ~150,000 recommendations on 7,766 companies from 433 brokerages. Time period: Jan. 1996 – June 2001. Findings: Analysts can rank stocks: Returns 1.4% per mo., 18% per yr . Returns are better if stocks have fewer analysts covering them. “That’s the great irony of our business. Portfolio managers don’t want us to downgrade stocks.” --DOR at Lehman “That’s the great irony of our business. Portfolio managers don’t want us to downgrade stocks.” --DOR at Lehman
