The U.S. dollar continues to weaken. Chart 1 shows the PowerShares US Dollar Bullish Fund (UUP) falling to the lowest level since the third quarter of 2011. One of the side-effects of a falling dollar is that it gives a boost to gold. And it's doing just that. Chart 2 shows the SPDR Gold Trust (GLD) gapping 3% higher today. In so doing, it is rising above a falling trendline drawn drawn over its August/September peaks. The 14-day RSI line (top of chart) is about to rise above 50 for the first time in two months. And the daily MACD lines (bottom of chart) appear poised to turn positive for the first time since August. Gold stocks are also rallying today along with other stocks tied to commodity prices.
