Entering Tuesday, nine of the top 10 non-leveraged exchange traded funds on a year-to-date basis were China ETFs. The outlier, the Guggenheim Solar ETF (NYSEArca: TAN), also features significant China exposure.

However, Tuesday was a dismal day for China ETFs after the Shanghai Composite endured its largest one-day loss in nearly four months while Hong Kong’s Hang Seng Index slipped to its lowest levels in two weeks. Yesterday, nine of the 10 worst-performing ETFs were China funds and six of those offenders were A-shares ETFs, funds tracking the stocks trading on the mainland exchanges in Shanghai and Shenzhen.

China ETF investors, particularly those holdings A-shares funds such as the Deutsche X-trackers Harvest CSI 300 China A-Shares Fund (NYSEArca: ASHR), KraneShares Bosera MSCI China A ETF (NYSEArca: KBA), Market Vectors ChinaAMC A-Share ETF (NYSEArca: PEK) and ASHR’s small-cap equivalent, the Deutsche X-trackers Harvest CSI 500 China A-Shares Small Cap Fund (NYSEArca: ASHS), might do well to closely examine the current state of affairs with the Shanghai Composite’s chart.

“The Shanghai Stock Market has been the hottest of the hot over the past year, up over 110%, which dwarfs the returns of the S&P 500 and Germany’s DAX index,” said Chris Kimble of Kimble Charting Solutions. “The rally over the past year put the Shanghai index at its 61% retracement level based upon the 2007 highs and 2008 lows. As the index was hitting this Fibonacci extension level, it created a reversal pattern (wick) last week. As it was hitting this Fibonacci resistance level, momentum was reaching overbought levels only seen at the 2007 highs.”

Tuesday’s slides cannot be ignored, but at the same time, nor can the strength displayed by A-shares ETFs this year. Confirming that strength is this factoid: ASHR, the largest U.S.-listed China A-shares ETF is up 33.4% this year, but that is not good enough to place the fund among the 10 best-performing ETFs.

A-shares ETFs have surged in almost straight line fashion since the start of March, prompting elevated valuations that are well above Hong Kong-listed stocks.

“While the Hang Seng China Enterprises Index soared 17 percent in April, the most since October 2011, A shares in China are still trading at a 31 percent premium to stocks in Hong Kong,” according to Bloomberg.

The Shanghai Composite “remains inside of a steep rising channel and this week is breaking a steep support line. Humbly, I remain of the opinion its important to keep a close eye on leadership. If the Shanghai index cools off, it could impact numerous global markets,” according to Kimble.

For traders looking to play a Shanghai Composite retrenchment, there is not yet an inverse A-shares ETF, though Direxion has such a fund in the works.

Bearish China ETFs currently available include the Direxion Daily FTSE China Bear 3X Shares (NYSEArca: YANG) and the ProShares UltraShort FTSE China 50 (NYSEArca: FXP). Those ETFs are the triple- and double-leveraged inverse answers to the iShares China Large-Cap ETF (NYSEArca: FXI).
