Gold prices are at record highs. Treasury bond yields are the lowest in decades. The U.S. dollar is swooning. The recent direction of exchange-traded funds tracking these asset classes can tell us a lot about the economy.

Although the markets don't appear to be locked in any downward spiral these days, it's hardly boom times. Investors are still worried about the present and not much more optimistic about the future, comments Tom Petruno for The Los Angeles Times. These concerns have had a negative impact on many corners of the market, but not all.

Gold, Treasury, and dollar ETFs have been on a tear this year, luring investor assets by the billions with every move in sentiment.

The euro appreciated against the dollar to a five-week high on Monday, and the dollar also depreciated to a 15-year low against the Japanese yen. Analysts credit the falling greenback to further reductions in the interest rates.

  • CurrencyShares Euro Trust (NYSE: FXE): up 5.9% in the last three months
  • CurrencyShares Japanese Yen Trust (NYSE: FXY): up 6% in the last three months

Furthermore, Goldman Sachs Chief Economist Jan Hatzius believes that the Federal Reserve will expand its purchases of Treasury bonds to as much as $1 trillion. The 10-year T-note dropped to 2.73% on Friday.

  • iShares Barclays 7-10 Year Treasury Bond Fund (NYSE: IEF): up 3.9% in the last three months; yields 3.05%
  • PIMCO 7-15 Year U.S. Treasury Index Fund (NYSE: TENZ): up 0% in the last three months; yields 3.04%

Investors who weren't too thrilled by the record low yields on Treasuries opted for commodity investments like gold, pushing it to new records this week. While this has sparked concerns of an imminent sell-off, for now, gold is enjoying its lofty perch.

  • SPDR Gold Shares (NYSE: GLD): up 3.5% in the last three months
  • iShares Comex Gold Trust (NYSE: IAU): up 3.5% in the last three months
  • ETFS Physical Gold Shares (NYSE: SGOL): up 3.4% in the last three months
