A CMBX contract is essentially a credit default swap on a pool of Commercial Mortgage-Backed Securities (CMBS). Both CMBX and Real Estate Investment Trusts (REITs) can be thought of as derivative contracts on commercial property values. This creates a tight fundamental link: our structural pricing model for CMBX, which is calibrated to REIT stock and option data, explains more than 86% of the daily price variation of CMBX contracts. We use the CMBX pricing model to document two large short-term deviations from market efficiency; consistent with price pressure by banks hedging their CMBS and commercial loan exposure using CMBX contracts. First, the model mispricing significantly predicts subsequent CMBX, but not REIT, price changes. The effect is economically meaningful: a strategy exploiting the predictability has an annualized Sharpe ratio of 2:35, net of transaction costs. Second, we show that following days with CMBS specific news, the CMBX market overreacts relative to the model for two days, which fully reverts over the next two days.
