In this article I will walk you through the commonly used but wrong way to think about volatility decay.We'll then walk through an example of volatility decay with realistic numbers.Afterwards, we'll build a simple mathematical model to calculate volatility decay from first principles.We'll compare the model with back-test simulations done on portfoliovisualizer.com.

The coronavirus impact looks to be ebbing, and the Brazilian government has been generous with demand-side stimulus measures.Manufacturing PMI, retail sales, loan growth, and services sector have also seen sequential improvements.Longer-term, commodity-rich EMs such as Brazil should benefit from the surge in liquidity.

The “middle income trap” may well characterize the experience of Brazil and most of Latin America since the 1980s.Conversely, South Korea maintained its pace of evolution, reaching a high-income status.Such divergence of economic growth can be related to their distinctive performances of domestic accumulation of technological and organizational capabilities.Their different approaches to global value chains and tradeglobalization reinforced such discrepancy in domestic accumulation processes.
