Walmart's 43.28x earnings multiple makes the stock impossible to buy for a long time. Its historical median is 31.13x, and even at 30x it would not be attractive. x.com 

Walmart may be setting up for a big bounce, with its pullback matching the pattern of its last two bottoms. The stock is down about 25% from its all-time high, as it was before both prior bottoms, which also showed RSI divergence. Its forward P/E has fallen from near 40 earlier this year to a more respectable 31, and it is holding just above the psychological $100 level near a prior breakout area. x.com 

Alphabet's earnings growth makes its valuation look attractive. It trades at 21x forward earnings and a 0.47 PEG while EPS grows 34% year over year; shares are down almost 9% year to date. Search still grows 12% and Cloud grows 103%, undercutting the concern that Search will sink the business. x.com  x.com 

Walmart and Costco are very overvalued while Nvidia is undervalued: per Charlie Bilello, Costco trades at 45x forward earnings, Walmart at 36x and Nvidia at 17x. A high multiple can be justified for a growth company like Nvidia, but not for Costco and definitely not for Walmart. x.com  x.com

Nvidia's rising revenue alongside a much lower P/E is getting hard to ignore. Its chart shows quarterly revenue above $80 billion in Q2 2026 while the P/E is around 30x, down from much higher multiples in prior years. x.com 

Walmart is expensive at 40 times forward earnings on a 3% net margin. That is nearly double Nvidia's 21 times, even though Nvidia earns a 63% margin. x.com
