Wondering what is driving market gains in 2017 amid increased volatility domestically and internationally? Analysts at Goldman Sachs Group Inc. (GS) - Get Report pointed to exchange traded funds in a note on Monday. 

ETFs are on track to purchase $380 billion in stock this year and owned nearly 6% of the U.S. stock market as of the end of the first quarter, according to an analysis by Goldman Sachs. As so-called passive investing instruments like ETFs have grown in popularity, active investment instruments like mutual funds have decreased in popularity. 

Mutual funds currently own just 24% of the stock market, according to Goldman, its lowest level since 2004. 

The firm also identified corporate buybacks and foreign investments as growth drivers for the stock market.
