Short Sales and Price Discovery in the Hong Kong Real Estate Market
研究香港间接房地产市场的卖空交易是否向直接房地产市场传递信息，发现卖空领先直接房地产回报，支持信息溢出机制，但该效应在金融危机后减弱。
Indirect real estate (IRE) returns are often shown to lead direct real estate (DRE) returns. Apart from differences in liquidity, transaction costs, and management skills, the DRE market is also less complete than the IRE market—when negative shocks arrive, one can only short IRE ( e.g ., real estate stocks or REITs), but not DRE. This study investigates if short sales in the IRE market convey any information to the DRE market. Based on high‐frequency (weekly) property price data in Hong Kong from 2000 to 2012, we find that short sales in the IRE market led DRE returns, even after controlling for the lagged IRE returns in a VAR model. This supports an information spillover mechanism in which the DRE market learns private information that is not reflected in IRE returns. The spillover effect, however, weakened after the recent global financial crisis because the increased uncertainty over the credibility of individual firms made short sales more reflective of firm‐specific information than real estate market fundamentals.
