Last week, Standard & Poor’s stripped Brazil of its investment-grade credit rating and some market observers believe further credit downgrades for the country are possible, perhaps in the near-term.

With that confluence of negative factors, it could be tempting for some investors to bet the worst news has been fully priced into Brazilian stocks. However, EWZ’s rapid descent could be a sign that it still is not safe for investors to dip their toes into these waters.

“The Brazilian economy is in shambles. Exports are in a free fall down 24% year-over-year. Industrial production is declining at the fastest year-over-year rate since 2009 and has had a negative year-over-year growth rate for 16 months. The unemployment rate has spiked to a five-year high while retail sales are declining at a pace last seen in 2003. Finally, even with excess capacity in the economy increasing and consumption slowing, Brazil is combating inflation as the CPI increased at 9.5% year-over-year rate in August. With this type of economic back drop its fairly easy to understand the pressure that Brazilian stocks have been under. What is harder to understand is how valuations have stayed so high,” according to a Seeking Alpha post.

In February, Moody’s downgraded debt issued by Petrobras (NYSE: PBR) to Ba2, two levels below investment grade, stoking speculation regarding Brazil’s sovereign credit rating.
