Fidelity MSCI Health Care Index ETF

Fidelity’s 10 sector exchange traded funds, introduced by the Massachusetts-based mutual fund giant last October, have amassed a combined $1 billion in assets under management.

“Assets in these exchange-traded funds have tripled from the start of 2014 and nine of the 10 Fidelity sector ETFs have more than doubled in size this year, reports Eric Balchunas for Bloomberg.

The outlier is the Fidelity MSCI Consumer Staples Index ETF (NYSEArca: FSTA), which had $31.4 million in assets under management as of May 31.

The other Fidelity ETFs with over $100 million in assets as of May 31 are the Fidelity MSCI Information Technology Index ETF (NYSEArca: FTEC), the Fidelity MSCI Health Care Index ETF (NYSEArca: FHLC) and the Fidelity MSCI Financials Index ETF (NYSEArca: FNCL) – also have more than $100 million in assets. The Fidelity MSCI Industrials Index ETF (NYSEArca: FIDU) could be the next Fidelity ETF to join the $100 million club as it had $96.6 million at the end of last month.

While Fidelity was late to the ETF game and faces intense competition for sector ETF dominance, from State Street (NYSE: STT) and Vanguard in particular, the Fidelity sector funds have some advantages. One of the most noticeable of those advantages is the 0.12% across the board annual expense ratio that makes Fidelity’s the least expensive sector ETFs on the market.
