NVIDIA BULL TREND FACES A MAJOR TEST Nvidia may be the most important stock to monitor when evaluating whether weakness in AI infrastructure is spreading into the industry's largest beneficiaries. Since April, Nvidia has traded within a rising parallel channel. On October 6, the stock briefly advanced to a new all-time high of approximately $243.37, extending above the channel's upper boundary in the chart interpretation. But the breakout failed to hold. NVDA subsequently reversed, fell back inside the channel, and continued declining throughout October. Now Nvidia is testing one of its most important long-term indicators: the 200-day simple moving average, near $204.38. A sustained breakdown below that moving average would weaken the longer-term technical structure and increase the possibility of a decline toward the lower boundary of the channel, around $190. That is the next major support level to watch. If $190 fails to hold, the correction could extend toward $170 or even $155.
