Abstract
The law of one price relies on enforcement by arbitragers who are expected to eliminate price differentials quickly. Arbitragers’ activities are constrained by liquidity of markets. However, large price differentials attract arbitrage activity enhancing the liquidity of markets. Using daily data on the NYSE index and related futures contracts, Roll, Schwartz, and Subrahmanyam (2007) document two-way Granger causality between the futures-cash basis and bid-ask spreads for stocks. We examine the issue using intra-day data on Indian single stock futures (SSF) contracts on Indian stocks and also consider the spread on the futures contracts. While the spreads in both the futures and cash markets affect futures-cash basis, we find that the futures-cash basis Granger-causes only the bid-ask spreads for SSFs but not the stocks.
