Abstract
AbstractThis paper examines the relative price discovery roles of near‐ and away‐from‐the‐money option markets. The evidence shows that, when considering multiple options with different strike prices jointly, option markets have an average information share of 17.6%. However, no individual option market dominates in the price discovery process, higher and lower trading activity options (i.e., near‐ and away‐from‐the‐money options, respectively) each contribute approximately equally to this process. The main implications of these results are that (1) collectively, option markets process a substantial amount of new stock price‐related information, and (2) looking across strike prices, option markets appear to be informationally nonredundant.
