semi stocks are at all time lows and PE levels. Don't let this doom and gloom piece prevent you from buying more
Intel trades at 5.5x PE for the last 12 months but 12.1x PE for the next 12 months (estimated, obviously). Intel specifically is also not at an "all time low" - they IPO'd in 1971 and have grown significantly since then.
I agree there are some bargains to be had in semi stocks, but keep in mind things may very well get worse before they get better.
And if you didn't buy till they were near their peak, did you really care about PE ratios?
