Trading in the Options Market around Financial Analysts’ Consensus Revisions
研究了金融分析师共识修正前约3天，期权投资者如何提前交易，并基于合成与标的证券的相对估值构建了扣除交易成本后仍盈利的零成本交易策略。
Abstract This article investigates the options market around a revision in the financial analysts’ consensus recommendation. The results demonstrate that options investors trade in the correct direction of the upcoming revision approximately 3 days prior to the announcement. We find this behavior in option-implied prices, implied volatilities, and options trading volume. Tests confirm that the options market leads the stock market before the financial analysts’ revision. Moreover, using all firms with outstanding options, an out-of-sample analysis produces a profitable zero-cost trading strategy net of transaction costs based on the relative valuations between the synthetic and the underlying equity security.
