Since the start of 2021, Qualcomm has been riding up and down the rankings in the SIA S&P 500 Index Report like a roller coaster, having completed multiple trips between the red and green zones. After climbing through the spring and into the early summer, QCOM has started to sink again lately falling out of the green zone back into the Yellow Neutral Zone. Yesterday, Qualcomm finished in 180th place, down 16 spots on the day and down 126 positions in the last month.
