How Valuable Are Target Price Forecasts to Factor Investing?
研究了分析师目标价预测在因子投资中的价值，发现基于共识目标价隐含预期收益率的策略能产生显著超额收益，并改善动量因子的风险回报特征。
The informativeness of financial analysts’ stock recommendations to investors has become the subject of much scrutiny and debate. This article investigates the investment value of target price (TP) forecasts under the specific angle of factor investing. It provides directions to quantitative portfolio managers for the integration of signals conveyed by those forecasts in systematic and rule-based investment decisions. Using TP data from 1999 to 2019 in Europe and North America, the author first documents a decline in analyst opinion on the performance of most equity factors and finds that their forecasts are style biased. He shows that a long-only strategy that picks best-ranked stocks according to consensus TP implied expected returns (CTPER) generates substantial alpha within large-cap, low-idiosyncratic-risk, and noncyclical stocks. Embedding the CTPER signal into the momentum factor helps materially improve its risk and return profile. Those findings support the idea of adequately using TP forecasts in the design of top-down multifactor portfolio construction frameworks.
