WILLIAMSTOWN, Mass. (TheStreet) -- A number of leveraged and inverse ETFs attracted capital at a fast clip last month, including ProShares UltraPro Short S&P 500 (SPXU) - Get Report and iShares DB Gold Short ETN (DGZ) - Get Report. SPXU saw $72 million net flow into the fund and finished July with $69 million in assets. DGZ saw net inflow of $31 million and finished the month with $44 million in assets.

Aside from the leveraged and inverse ETFs, here are the ETFs with the largest inflows as a percentage of assets.

iPath S&P 500 VIX Short Term Futures ETN

(VXX) - Get Report

saw $273 million flood into the fund as it grew to $408 million in total assets.

Market Vectors Brazil Small Cap

(BRF) - Get Report

had net inflows of $59 million, while $34 million poured into

iShares Peru

(EPU) - Get Report

.

Market Vectors Indonesia

(IDX) - Get Report

gathered $27 million in assets, while

iPath DJ UBS Nickel ETN

(JJN) - Get Report

and

iPath DJ UBS Sugar ETN

(SGG) - Get Report

each attracted $7 million in assets.

Other notable growers were

Vanguard Mega Cap 300 Growth

(MGK) - Get Report

, which saw assets grow to $494 million after gaining $203 million in net inflows.

ProShares UltraShort FTSE/Xinhua China 25

(FXP) - Get Report

added $117 million and closed July with $270 million in assets.

ETFs seeing major outflows as a percentage of assets were led by

Direxion Daily Financials Bull 3X

(FAS) - Get Report

. It went from $1,771 million in assets at the end of June to $1,041 million at the end of July after suffering a $984 million outflow. On a percentage basis, but far less in terms of nominal dollars,

iPath DJ UBS Cocoa ETN

(NIB) - Get Report

saw its assets fall 50% after $2 million left the fund.

ProShares UltraShort Silver

(ZSL) - Get Report

,

PowerShares Dynamic Food & Beverage

(PBJ) - Get Report

and

PowerShares Dynamic Banking

(PJB)

rounded out the bottom five.

Repeating the findings from yesterday's article on the funds with

the largest inflows and outflows

, it's obvious that bearish investors are finding a use for the inverse ETFs as well as short-term VIX futures-tracking VXX. That fund rolls the first and second month VIX futures contracts. VXX declined as the market rallied, sending shares down 45% from $113 at the end of March.

iPath

also offers a midterm VIX ETN:

iPath S&P 500 VIX Mid Term Futures ETN

(VXZ) - Get Report

, which is less volatile. It lost 25% over the same period, but it will also gain less if the VIX spikes during a market panic. VXZ rolls the fourth, fifth, sixth and seventh month futures contracts.

Also, the data shows that

Vanguard

is hitting its ETF stride. Its funds are competitive with

iShares

and

SPDRs

and the intense competition will eventually lead to lower expense ratios across the industry.
