On Construction of Stochastic Pricing Operator from Asset Market Data

Tanigawa, Yasuhiko
Abstract
Constructing IMRSs from asset market data has an advantage, that is we need not rely on troublesome consumption data. When we observe a subset of the market, however, there are two problems. First, the constructed IMRSs may not price the other assets. Second, we may also end up insufficient number of factors. These two difficulties lead to mis-pricing of APT. We find an IMRS constructed from only stock market data does not price the Government long-maturity bonds. Using both the stock returns and the one-month Treasury bill returns, this mispricing disappears. We also find that five factors extracted from both the stock returns and the Treasury bill return satisfies the condition for APT implied by the Euler equation.
