The FT highlighted large, recent premium and discount moves in the Market Vectors Russia ETF (NYSEArca: RSX) and the SPDR S&P Russia ETF (NYSEArca: RBL), noting that RSX traded at a 5.8% discount to NAV earlier this month before surging to a 9.5% premium last week. Just this month, RBL has seen both its largest discounts and premiums to NAV, according to the FT.

Recently, the Deutsche X-trackers Harvest CSI 300 China A-Shares ETF (NYSEArca: ASHR) also traded at a large premium to NAV after Deutsche Asset & Wealth Management, the ETF unit of Deutsche Bank, was forced to limit creations in ASHR because strong demand forced the ETF to bump up against its Renminbi Qualified Foreign Institutional Investor (RQFII) quota, which allows the funds to purchase A-shares equities.

DAWM has since announced its RQFII was raised, allowing for increased creations of ASHR.

Still, evidence suggests that some ETFs that hold illiquid assets are able to absorb bouts of volatile trading. For example, in June 2013 the iShares iBoxx $ High Yield Corporate Bond ETF (NYSEArca: HYG) experienced its largest trading day to date, but the ETF still saw the average ratio of “average secondary-to-primary ratio for the fixed income ETF category,” according to BlackRock and closed at a mere 81-basis point discount to NAV.
