Thursday's ETF Winners & Losers

Bundled securities tracking overseas markets suffered some of the steepest declines of Thursday's session, after French bank BNP Paribas said it has suspended three of its funds that have exposure to U.S. credit markets due to the inability to accurately value the hedge funds.

Worries about the possible spread of subprime problems were punishing European bourses. Paris' CAC 40 was losing 2.1%, Germany's Xetra Dax was down 1.8%, and London's FTSE 100 was falling 1.7%.

The iShares MSCI Belgium Index (EWK Quote) was lower by 96 cents, or 3.7%, to $25.63. The iShares MSCI Netherlands Index (EWN Quote) was falling 99 cents, or 3.2%, to $29.64. The Vanguard Emerging Markets Stock (VWO Quote) ETF was losing $3.33, or 3.5%, to $92.07.

ETFs related to lenders and banks were also suffering in the wake of BNP Paribas' news. JPMorgan Chase (JPM Quote), Lehman Brothers (LEH Quote), Citigroup (C Quote) and Bear Stearns (BSC Quote) all slid by 3% or more.

The KBW Bank (KBE Quote) ETF was shedding $1.80, or 3.3%, to $52.64. The Regional Bank HOLDRs (RKH Quote) lost $4.39, or 2.9%, to $146.49. The iShares Dow Jones U.S. Financial Services (IYG Quote) was down $3.78, or 3%, to $121.48. The Financial Select Sector SPDR (XLF Quote) slid 94 cents, or 2.7%, to $33.81.

Silver-related ETFs also lost ground, as silver futures tumbled 37 cents to $12.80 an ounce. The iShares Silver Trust (SLV Quote) was sliding by $4.13, or 3.2%, to $126.41. The PowerShares DB Silver (DBS Quote) was falling by 84 cents, or 3.2%, to $25.

Meanwhile, the United States Natural Gas (UNG Quote) ETF was jumping 4.5% as natural gas prices jumped 33 cents to $6.55 per million British thermal units. The gain comes after the Energy Department said that natural gas inventories rose by 42 billion cubic feet last week. The ETF was adding $1.79 to $41.48.

Bundled securities tracking real estate were also higher. The iShares FTSE NAREIT Residential (REZ Quote) was higher by $1.90, or 4.2%, to $46.73. The Ultra Real Estate ProShares (URE Quote) was gaining 62 cents, or 1.4%, to $46.03. The iShares Dow Jones U.S. Real Estate (IYR Quote) was up 54 cents, or 0.7%, to $75.14.
