Since then, it has weakened further to make a lower low and has broken below triangle support, as shown below on the Weekly ratio chart of DBC:SPX. There is a slight positive divergence on the Momentum indicator, but it has not hooked up yet.
DBC has also made a lower low in a downtrend in between the Weekly 50 sma (red) and 200 sma (pink) below a major support level of 27.47, as shown on the Weekly chart below. Of note is last week's volume spike and this week's bounce, thus far.
The AUD/USD forex pair is also in a downtrend on the Weekly timeframe, as shown on the chart below. It has bounced this week from a major support level at 1.01 and is trading just below major resistance at 1.0274-1.03ish.
Three charts to watch to see if momentum begins to rally on the DBC:SPX ratio to, potentially, signal that the Commodities Sector is set to join in on any further equity rally...particularly if DBC can rally to and hold above 27.47, if AUD/USD can rally and hold above 1.03, and if DBC:SPX can rally and hold above triangle resistance at 0.019.
Otherwise, we may see considerably more weakness in the Commodity sector, and possibly, in the Aussie $.
