EWZ Analysis

iShares MSCI Brazil Capped (EWZ)

Update 4/19/2017: EWZ continued a sideways correction that began in early March as time decay worked to bring the position to profitability. I exited at 18.2% of maximum profit.

Shares showed a net decline of 3.1% over 21 days, or a -54% annual rate. The options position produced a 22.3% yield on debit for a +387% annual rate.


EWZ, an exchange-traded fund, has sufficiently high implied volatility to support a trade for the nearer term, although it is quite low compared to the annual range.

I shall use the MAY series of options, which trades for the last time 51 days hence, on May 19.

Implied volatility stands at 32%, which is double the VIX, a measure of the volatility of the S&P 500 index.

EWZ’s IV stands in the 25th percentile of its annual range and the 75th percentile of its most recent broad movement.

The price used for analysis was $37.81.
