Price Discovery in the Stock, OTC Corporate Bond, and NYSE Corporate Bond Markets
This paper examines intraday price discovery in three closely-related U.S. markets: stocks, Over-The-Counter (OTC) corporate bonds, and New York Stock Exchange (NYSE) electronically-traded corporate bonds. We calculate the Hasbrouck (1995) information shares of these three markets over five years. We find that OTC corporate bond trades have a 5.7% information share, despite zero pre-trade transparency in the OTC market. Further, NYSE corporate bonds have a 45.8% information share, despite having a tiny market share, because of publicly-displayed, frequently-updated bid-ask quotes that can be traded at any time. OTC corporate bond information shares are inversely related to credit quality and are relatively constant over time. This is consistent with multi-security informed trading theory and the Merton (1974) corporate bond model. NYSE corporate bond information shares are positively related to their update frequency. Thus, the subset of NYSE bonds that are updated more frequently are more informative.
