GREK is a well established ETF that tracks a market-cap weighted index of Greek equities. When the Athens stock market closed in late June 2015, GREK continued to trade in New York. During that period the ETFs issuer used fair-value estimates of the dormant stocks a reasonable stepwhich explains the large gap down in NAV vs. the frozen index when the market closed. The index caught up with the NAV when markets reopened in early August. The fund mostly traded at a premium during that time as APs were unable or unwilling to step in to drive the price down closure to NAV. Still, GREK functioned well during the crisis. GREK made a material change to its underlying index on March 1 2016, switching to the capped MSCI All Greece Select 25/50 Index from an FTSE index. In all, GREK continues to provide extremely concentrated but reflective exposure to Greek equities in a viable wrapper.
