Source, the 10^th-largest European ETF provider, became the second-fastest-growing exchange-traded product provider in Europe this year, as investors used its two volatility-linked products as a safe haven in the equity market sell-off, according to an article published in the Financial Times.

Source’s two volatility-based ETFs brought in $660 million during the first quarter, bringing total inflows for the ETF provider close to $1.2 billion for the quarter, according to FT.

Also contributing to Source’s success is a new system known as Voltage—a product developed with the help of Nomura—which attracted $490.8 million last quarter, the FT report said.
