Earlier quoted context omitted.
The forward PE is 31 for AMD, and Nvidia is at 33. Apple's forward PE is 26. The market prices are based on future expectations. Nvidia is expected to increase earnings by something like 3x, and AMD by 10X
How does one find information on forward P/E? Are there historical forward P/E charts to get some context on whether the current prices are expensive / in-line with how tech is valued over the past ten.. twenty years? Thanks!
Since you aren't going to have an account with every broker to get their research, instead you'd sign up for one of Capital IQ, FactSet or Bloomberg which aggrgate the info for you and are listed here in increasing order of price and quality
Banks would have the chart you're looking for but they're fairly easy to recreate if you have the data. (Source: I worked in M&A for nearly a decade in such banks)
