How Human Genome Moved the ETFs

Posted 7/20/2009 5:20 p.m. EDT

Human Genome Sciences ( HGSI) delivered surprise news when it announced that its lupus drug achieved statistically significant success in a clinical trial; its stock more than tripled, up 270%.

The SPDR S&P Biotech ( XBI) doesn't hold any shares of HGSI, and it had a return of just over 1%. At 0.16% of assets, HGSI didn't make much of a dent in iShares Nasdaq Biotech ( IBB), which also had a 1% rally.

PowerShares Dynamic Biotechnology & Genome ( PBE), however, had 3.43% of assets in HGSI at the start of the day, enough to fuel a 10% rally in shares of PBE. Finally, First Trust NYSE Arca Biotechnology Index ( FBT) spreads its assets evenly across 20 biotech stocks, among them HGSI. The more than tripling of HGSI delivered most of FBT's 15% return on the day.

Besides biotech funds with large exposure to HGSI, Market Vectors Russia ( RSX) and Market Vectors Indonesia ( IDX) were winners, up more than 6% and 4%, respectively.

Currencies ended up being strong plays as well, as I mentioned this morning. PowerShares DB U.S. Dollar Bearish ( UDN) gained 0.7% on the day, about where it started. CurrencyShares Australian Dollar ( FXA) climbed to a 1.9% return, while thinly traded WisdomTree Dreyfus New Zealand Dollar ( BNZ) added 2.5%.

WisdomTree Dreyfus Brazilian Real ( BZF) advanced 1.6%, and WisdomTree Dreyfus Emerging Currency ( CEW), which holds 12 emerging-market currencies, including the Brazilian real, Indian rupee, Chinese yuan, South Korean won, Polish zloty and Taiwanese dollar, gained 1%.
