Last Friday saw some wild moves in commodity markets that caught everyone's attention.

Silver and platinum both surged over 10% in a single trading session—the kind of spike you rarely see outside extreme market conditions. This kind of aggressive upside action has shown up before during major rallies, particularly back in the 2010s and during the 1970s boom. But here's the thing: these moves never stick around.

When you get spikes like this, they typically signal the tail end of a run, not the beginning. The momentum fades fast. Coming into next week, traders should be watching carefully to see if this reversal pattern plays out the way history suggests it usually does.
