Nasdaq 100 Stocks to Watch: AMD on the Rise, PANW and WMT Under Pressure

The Nasdaq 100 is home to some of the biggest tech success stories, but certain stocks face challenges such as profitability concerns and rising costs.

Palo Alto Networks (PANW) has a gross margin of 72%, which is below its competitors', leaving less money for investment in areas like marketing and R&D. The company also operates in a highly competitive environment with long payback periods on sales and marketing expenses.

Another stock facing challenges is Walmart (WMT), which has faced growth challenges with annual revenue increases of only 5.3% over the last three years, falling short of other consumer retail companies. The company's low gross margin of 24.9% and poor expense management have led to an operating margin of 4.2%, below the industry average.

In contrast, Advanced Micro Devices (AMD) stands out with exceptional market share growth, increasing its revenue by 33.2% annually over the last two years. The company's earnings per share have comfortably outperformed the peer group average over the last five years, increasing by 22.6% annually.
