Micron's AI memory-chip sales and accelerating growth support its upside case. Its 3.3/5 WATCH rating reflects a business with 60% of sales from cloud and data-center chips, 64 cents of profit per sales dollar and 256% sales growth last year. At the Oct. 15 close of $878.84, it traded about 42% below estimated fair value of $1,512.34. The case needs strong sales growth and expanding margins and cash flow; slower growth or a price outrunning the business are warning signs. x.comÂ
