About The Presentations
This session has project presentations by two of our esteemed EPAT alumni. First on “Pair Trading In the Brazilian Stock Market” by Dr Luiz Guedes, Brazil; and second on “Backtest of Short Straddles on SPX Index” by Siddharth Bhatia, UAE.
Project 1: Pairs Trading In the Brazilian Stock Market
The complete project: Statistical Arbitrage - Pair Trading in the Brazilian Stock Market
This project models a Statistical Arbitrage pair trading strategy to Brazil’s B3 (former Bovespa) stock market exchange. We run our strategy on two distinct time intervals. From 1-Jan-2009 to 31-Dec-2014 and from 1-Jan-2018 to 30-Apr-2021. As we only had current sector distribution available, the results for the former period clearly suffered from survivorship bias.
Stock sector classification was downloaded directly from Brazil’s B3 stock market exchange. From all sectors, we considered only the ones with five or more stocks, namely: oil, metal, steel, paper, transp_material, machines, rail_roads, highways, storage, services, agriculture, meat, food, construction, fabric, clothes_shoes, education, car_rental, retail, hospitals, drugstores, it, telecom, electricity, water, banking, financial_services, insurance and real_estate.
Results were very encouraging, though did not consider transaction fees or slippage costs. All calculations were done based on daily close prices.
Project 2: Backtest of Short Straddles on SPX Index
There are numerous studies that talk about mechanically selling option straddles and/or strangles on stock indices like the SPX, NIFTY, BANKNIFTY etc. It’s deemed to be profitable in the long run due to a persistent market risk premium called ‘variance risk premium’.
This exists because of an overpricing of implied volatility above the actual realized volatility of the index. Market participants overpay for options due to fear/uncertainty hence index options are usually overpriced. During normal market regimes, options with a longer expiry are priced at higher vols than near term expiries.
This is a simple strategy of mechanically selling 45-60 day straddles every week on the SPY ETF and delta hedging once a day. For the avoidance of doubt, a straddle is an option position where one sells the At The Money Call and Put option together for a net credit into the account.
It works when the underlying exhibits lower volatility than initially priced by the options sold. In simpler terms, it works when the underlying doesn’t move around too far and too much from the chosen ATM strike at the initiation.
The profit is roughly the difference between Implied Volatility at initiation and Realized Volatility at cessation, multiplied by the straddle’s vega exposure.
