Guggenheim Solar ETF (TAN) - Get Report 5.3%

Although TAN sold off a bit during Friday trading, it was not enough to offset the gains seen from this solar energy ETF throughout the rest of the week. This fund continues to gain steam, aiding to my theory that it may make a strong play as we head into the close of the year.

Although the fund's prospects are bright, investors must keep a close watch on this industry. Solar and other alternative energy companies are heavily reliant on government subsidies to remain profitable. As companies cut back on spending in hopes of reigning in debt, these payouts remain threatened.

iPath Dow Jones UBS Sugar Total Return Subindex ETN (SGG) - Get Report 2.8%

Sugar prices continue to power higher helping SGG to not only recover its losses felt during its early 2010 breakdown, but also flirt with new all-time highs.

Agricultural commodities have seen an impressive rise and I continue to view the farming industry as an area of strength. However, playing this slice of the market can be tricky. SGG may run into headwinds as it approaches these atmospheric levels which may send the fund for a loop. A better way to play food price increases is through a more diversified fund such as

iShares Silver Trust (SLV) - Get Report 4.4%

Precious metals continue to power higher this despite seeing some sell-off during the tail end of the week. Among physically-backed products, silver lead the pack. In the realm of precious metal miners ETFs, the

Market Vectors Junior Gold Miners ETF

saw some of the strongest gains.

Despite seeing strong earnings from companies such as

the markets remain jittery. Precious metal ETFs will aid investors in weathering economic turmoil.

Losers

iPath S&P 500 VIX Short Term Futures ETN (VXX) - Get Report -6.5%

Despite the economic volatility that persists in the market, the volatility index-tracking ETNs got battered this week. The short-term futures-tracking VXX got hit particularly hard, causing it to tumble to brand new all time lows.

Although VXX may appear attractive trading at such low levels, I would advise investors against trying their luck with this or any other VIX-based fund. It is unclear how far they will fall.

SPDR KBW Bank ETF (KBE) - Get Report -4.5%

As the markets continue to sort out the overall effect of the sweeping foreclosure issues, the financials took a beating. KBE is designed to track a diverse basket of banks representing both Wall Street kings and regional institutions.

Looking to next week, KBE will be exciting to watch as a slew of financial institutions such as

Citigroup

(C) - Get Report

,

Bank of America

(BAC) - Get Report

and

Wells Fargo

(WFC) - Get Report

present their quarterly earnings reports.

iShares 20+ Year Treasury Bond Fund (TLT) - Get Report -3.8%

Investors shunned long term U.S. treasuries this week in favor of riskier asset classes. This in turn caused TLT to fall throughout the week. By Friday, the fund was trading below its 50-day moving average at levels last seen in August.

Although fixed income remains an attractive region of the market due to market jitters, interest in treasuries appears to be waning. Investors may want to check out a dividend-oriented fund such as
