The NYSE and Nasdaq are halting trading in several Russia-based stocks that list on their exchanges. There are five Russian ETFs that trade in the U.S., VanEck Russia ETF (RSX) and iShares MSCI Russia ETF (ERUS) are two of the largest that continue to trade even though their stocks are not trading in Russia.
ETF Newz Says: RSX is down nearly 50% in 5 days. ERUS is down approximately 49%. In the past when the Greek stock market closed for 5 months, Greek ETFs continued to trade as well.
