Nvidia fell in early trades Monday but remained below a key level of support after chip titan Broadcom reported results last week. Its 50-day moving average is an important level of support, and Nvidia fell below it for the first time since Sept. 12 on Tuesday last week — ending a nearly three-month-long feat. If you look back at its chart, Nvidia has not made much progress after it broke out at the buy point of 140.76 in October.
