These were last week’s top performing leveraged and inverse ETFs. Note that because of leverage, these kinds of funds can move quickly. Always do your homework. While ProShares’ UltraShort Silver Fund ( ZSL A ) was this past week’s big winner at over 32%, it was oil and energy funds that dominated. Fully half of the chart this week were devoted to energy funds, from the MicroSectors U.S. Big Oil Index -3X Inverse Leveraged ETN ( NRGD ) gaining almost 30% returns to the more modest 18% by the ProShares Ultra Short Oil & Gas fund ( DUG B+ ). Unfortunately only one of those energy funds saw any inflows for the week, and at just $3.46 million, investors weren’t particularly keen on the Direxion Daily Energy Bear 2X Shares Fund ( ERY B ) either. In fact, ERY and ZSL were the only fund out of our top performers to attract any new assets this week. The biggest loser was the Direxion Daily Junior Gold Miners Index Bear 2X Shares Fund ( JDST ), which saw outflows of over $42 million, despite returns of 21%.
