一般注記type:Working Paper
We document the determinants of the expectation heterogeneity of stock price forecasters on the TOPIX. Monthly panel data surveyed by QUICK Corporation in the Nikkei Group is utilized in the process. We examine the determinants of expectation heterogeneity by categorizing our sample into buy-side and sell-side professionals，and demonstrate that expectation heterogeneity arises as a result of the co-existence of different types of
professionals within the same market. We show that the buy-side and the sell-side
professionals，who have different business goals，differentiate the information contents as well as their interpretations of the same information in their forecasts，contributing to the expectation heterogeneity. In addition, we investigate the interactive expectations formulation
of buy-side and sell-side professionals. We find that buy-side professionals incorporate the sell side’s ideas regarding the future stock prices into their own forecasts，although they exclusively refer to their own ideas when relating foreign exchange rates to the future stock prices. Meanwhile, sell-side professionals tend to utilize buy-side professionals' ideas about future prices in order to improve their research and ingratiate themselves to their clients,i.e.,
the buy-side professionals. We demonstrate that this interactive expectations formulation also contributes to the generation of the expectation heterogeneity.
