(Bloomberg) —A procession of shocking news out of Saudi Arabia, including the arrests of dozens of high-profile nationals, sparked a whipsaw session in the country’s stock market, which initially sold off as much as 2.2 percent before paring losses to end the day with a gain of 0.3 percent.

The volatility may carry over to other equities.

BlackRock’s iShares MSCI Saudi Arabia Capped ETF, ticker is KSA, is the sole U.S.-listed exchange-traded fund that aims to track an index of stocks from that country, such as the top-weighted chemicals company Saudi Basic Industries. While the ETF may see interest in Monday’s trading, it’s small, with assets of just $17.6 million. An average of about 10,600 shares have traded daily in the security this year, compared with 69.6 million in the SPDR S&P 500 ETF.

Most of the potential stock movers are directly related to investments by billionaire Prince Alwaleed bin Talal, who was among the arrested.

Citi (C): Alwaleed’s 95 percent-owned investment vehicle Kingdom Holding Co. has held shares since 1991, boosting its stake during the 2008-09 financial crisis.
