“After a dismal year-end, Russian equities have turned a corner in 2012. A 20% increase in Moscow’s RTS Index has drawn international investors back into the market: Russia-focused mutual funds recorded $237 million in inflows in the seven days to February 1 — the highest weekly volume of inflows since April 2011. Including Russia-oriented money in broader funds, the total is $414 m, also the highest since last April,” the Financial Times reported Monday. [ETF Chart of the Day: Russia]
