Bovespa assimilates with the world’s leading indices

Earlier this year, a working party commissioned by the BMF&Bovespa to look into its increasingly antiquated volatility-driven methodology of the Ibovepsa made its unanimously-approved set of recommendations to Brazil’s stock exchange. According to one member of the working group (which comprised of bankers, portfolio managers and brokers) despite commissioning the group the exchange had been signalling reluctance to part with its 46 year-old methodology.  Renata Cabral, quantatitive analyst at Corretora Santander in São Paulo says the decision to switch methodologies came as a surprise: “Investors and analyst weren’t expecting this,” she says. “The Bovespa was concerned about changing its methodology because it has a good track record but this is good news.”

But recent cases, not least the example of OGX, had clearly shown the problems that weighting on volatility can bring: the oil company’s shares fell 91% in 2013 during a turbulent and volatile period for the stock, which increased the company’s weighting on the index. “Even as the company was close to filing for Chapter 11[style bankruptcy protection] OGX was the third largest stock on the Bovespa so clearly they realised the problem of the liquidity methodology and decided to make a change,” says one banker who declined to be named.
