$NVIDIA(NVDA.US)'s forward P/E ratio is only around 20 now, less than 30, the lowest among the seven giants, even lower than $Alphabet(GOOGL.US). At this price, the risk-reward ratio is favorable. A big drop would be a buying opportunity—buy with confidence. I can't speak for the other six giants, but I can say this about NVIDIA. Unless the AI bubble bursts next year, but we're far from that point. When many in the market are still worried about an AI bubble, it's still early. You won't hear such doubts right before a real bubble burst.
