A lot of tech stocks are expensive, as I said a while back. Nvidia are currently at a P/E of about 48, which is about three times that of an averagely priced stock. So basically, you could choose to buy $3,000 of Nvidia stock, or $1,000 of typically priced companies and expect the same earnings. Still sound a good deal?
Of course, companies prospects do differ. A quickly growing company may be worth more than a P/E of 16. But generally, a figure of 48 is just too high.
Interestingly, Apple have a P/E of 16.8 at the minute, despite not being too far off an all time high. The market is still a it crackers. Alphabet are at 59. Amazon are 229! Even Microsoft are nearly 61. Lot of hype at the moment, despite recent corrections (which are small in the scheme of things).
