I think I stumbled onto a live, retail-sized merger-arbitrage case and would love a sanity check from folks who’ve actually done this in India. Watching the JSW Ispat Special Products share price vs JSW Steel, it seems to loosely track an implied swap parity around the merger/corporate actions, but the spread moves more than I expected. This looks “simple” on paper, but the mechanics for a small investor feel messy.
Questions I can’t find clean answers to:
- Calculating real-world parity: Beyond the headline swap ratio, how do you adjust for stamp duty, STT, brokerage, and expected tax treatment so the parity you trade is apples-to-apples? Any template you use to avoid false signals?
- Hedging without liquid F&O: If the smaller leg is T2T or lacks futures, how are you hedging the parent/target? Anyone using SLB (stock lending/borrowing) on the India exchanges to short the parent leg? How bad are borrow costs/recall risks in practice?
- Settlement timeline and IRR: From record date to credit of new shares and ability to sell, what timeline do you budget for? In your backtests, how much does this lag crush IRR vs the headline spread?
- Circuit limits and liquidity traps: Practical tips to avoid getting stuck near record dates when volumes dry up or daily circuits hit? Any rules of thumb on minimum spread you demand to compensate for execution friction?
- Tax treatment of the swap: If it’s a court-approved merger, is the share exchange tax neutral at swap time? Does the holding period “tack” onto the new parent shares for LTCG purposes, and how do you compute the cost basis you’ll use on exit? Any past examples where the AO treated it differently?
- Odd lots and fractional entitlements: How are fractions settled (cash vs consolidated lots later)? Any hidden costs or delays that matter to small accounts?
- Basis risk from the steel cycle: Since steel spreads can swing with ore/coking coal, how do you manage the underlying beta if the spread blows out while you wait for the corporate timeline?
- Data and tooling: Anyone willing to share a simple parity tracker (Google Sheets or Python) that ingests live quotes of both legs and flags when the spread clears fees/taxes? Free data sources that are “good enough”?
If you’ve traded the JSW Ispat vs JSW Steel situation specifically, what were the gotchas you wish you’d known? If the safe answer is “skip arb and just own the parent,” I’m also curious why-governance, delays, or the steel cycle swamping the spread?
This seems like an awesome learning case for retail-friendly merger arb in India, but I don’t want to mistake a mirage for free money.
