Gold prices are starting today on a stronger foot, buoyed by the rebound yesterday - especially in US trading. At some point, gold touched a near four-week low at $4,282 this week but is now seen trading back up to $4,420 levels today. So, what's behind the rebound in gold and what does the chart has in store for us next?The fundamental push: Gold has been suffering in the past week due to soaring bond yields globally. That has weakened appetite for holding gold, which pays zero interest. At the same time, a stronger dollar channel also works against the precious metal.The technical play: Gold's retreat since Jackson Hole sees price fall back below both the 100 and 200-day moving averages, before arresting the drop near the 50.0 Fib retracement level of the swing higherfrom July to August (chart below). That is now keeping buyers back in the game but there is still more work to be done to recapture the upside momentum.Key risk levels to watch out for: The 100-hour moving average, seen at around $4,428 currently. Keep below that and sellers remain in near-term control.Key risk event to watch out for: The US jobs report/non-farm payrolls tomorrow.During the past week, gold has declined due to surging bond yields across the globe. That also reignited some appetite in the dollar, before yields came off the boil yesterday. The retracement in yields is helping to grant gold a bit of a breather for the moment, erasing much of the losses from this week.The rebound also comes as we see a technical bounce off the 14 August low of $4,311 and the 50.0 Fib retracement level of the swing higher from July to August at $4,328. Those now define key downside risk levels for gold from a technical perspective.Does this mean that gold is poised for a return back to the upside? Not so fast.The near-term chart above shows that there is a challenge near the 100-hour moving average (red line) now at around $4,428. Buyers need to push above that in order to break the more bearish near-term momentum since last week.But even in doing so, there is further resistance seen from the 200-hour moving average (blue line) at around $4,528 - which also rests near the 200-day moving average at $4,532. So, those are key upside levels that may limit any run up in the precious metal before the weekend.In terms of key risk events, all eyes now turn to the US jobs report tomorrow to see how that may impact the bond market. And in turn, that will also have a spillover impact towards gold. This article was written by Justin Low at investinglive.com.
