Over more than two decades in markets, John-Mark Piampiano has traded his share of volatility. Managing derivative portfolios over the years from both the long side and the short side of the carry ledger and across the spectrum of listed and OTC products, John-Mark is a keen observer of change in market structure, trading technology and the provision of liquidity.  Our discussion considers the manner in which price discovery in equity option markets has evolved, now well represented on the screens through pricing engines that are entirely automated.  In this context, we explore the implications of much tighter screen bid/offers for the buy-side and sell-side alike.  Gone are the days where obvious pricing dislocations come about from concentrated option buying or selling activity in one name and one part of the vol surface.  The result, a greater degree of market efficiency and increased importance on trading technology to find and implement trades that capitalize on smaller relative pricing discrepancies.  We talk as well about running a tail risk program and the challenges that come from carrying protection during very quiet periods.  Noting the increased tendency for market vol regimes to transition very quickly, John-Mark shares his thoughts on how investors should think about hedging, emphasizing the need to have an action plan to monetize premium expansion during a market sell-off.  Please enjoy this episode of the Alpha Exchange, my conversation with John-Mark Piampiano.
