Knowledge that Transforms

We construct two types of trading shocks and examine their effects on stock prices. Common shocks capture the shared trading activity across funds, whereas granular idiosyncratic shocks place emphasis on large players. Common shocks related to stock sales exhibit a significantly stronger price impact than those related to purchases, in contrast to symmetric effects of purchases and sales for granular idiosyncratic shocks. The initial price impact persists in the short run and partially reverses after six months, suggesting underreaction to institutional trading. Our results underscore the impact of the common component across various funds on asset prices and market efficiency.

This paper documents coarse pricing by the U.S. Federal Reserve’s counterparty intermediaries in quantitative easing operations. Although the Fed explicitly sets a tick size of 1/256th in its reverse auctions to purchase Treasury securities, offer prices of primary dealers exhibit strong clustering on coarser grids. Top dealers price more finely, and coarse pricing is particularly prevalent when the security characteristics indicate greater difficulty in precise pricing. I argue that this coarse pricing results from information costs associated with increasing pricing precision. The results also point to a novel role of tick size in affecting dealer competition in central bank operations. • The Federal Reserve purchases U.S. Treasury securities through reverse auctions for quantitative easing(QE). • This paper documents coarse pricing by the New York Fed’s primary dealers (PDs) in these auctions. • PDs with larger market shares engage less in coarse pricing. • Cross-sectional analysis reveals that information costs of increasing price precision drive this dealer behavior. • Policy implications are discussed.
