摘要: |
We analyze a market-wide panel dataset on retail options from India, which has an 80% share in option contracts traded worldwide. Retail participation dominates and is concentrated in index options. Traders exhibit short-term speculative behavior with day trading and short-duration directional bets especially as options converge to 0DTE. Three natural experiments indicate that financial constraints and lottery-like preferences drive investor behavior. An exogenous supply shift induces trading and shifts volume to short-term options. Lot-size increases and delivery margins targeting speculation are offset by speculative shifts to cheaper and riskier options. While stock market inclusion and participation increase welfare in canonical household finance models, they can also entrench speculative behavior that is difficult to undo. |
