Comex gold had a positive weekly chart a month ago, but the technicals turned on a dime after Donald Trump was elected president. After nearly testing my risky level for November with a high of $1,338.3 the Troy ounce on Nov. 9, gold futures plunged to as low as $1,158.6 on Dec. 5, down 13.4%. By Nov. 18, the weekly chart became negative, then oversold.

Despite being in correction territory, Comex gold is still 12.2% above its Dec. 3, 2015, low of $1,045.4, and has a gain of 10.6% year to date.

Investments in gold equities have been even more volatile.

The VanEck Vectors Gold Miners ETF (GDX - Get Report) , Barrick Gold (ABX) , Yamana Gold (AUY - Get Report) , Goldcorp (GG) and Newmont Mining (NEM - Get Report) are deep in bear market territory after their 2016 highs, but they are also in bull market territory vs. lows set in 2015 or 2016. These investments still have solid year-to-date gains, outperforming the precious metal itself.

Here's a scorecard for Comex gold, the gold ETF and the four gold mining stocks.

 

The weekly chart shows a red line through the price bars, marking the key weekly moving average (a five-week modified moving average). The green line is the 200-week simple moving average, the "reversion to the mean."

The study in red along the bottom of the chart is weekly momentum (a 12x3x3 weekly slow stochastic), which scales between 00.00 and 100.00, where readings above 80.00 indicate overbought and readings below 20.00 indicate oversold.

A negative weekly chart shows the stock below its key weekly moving average, with weekly momentum declining below 80.00 in a trend toward 20.00. A positive weekly chart shows the stock above its key weekly moving average, with weekly momentum rising above 20.00 in a trend towards 80.00.
