$S&P 500 Index(.SPX.US)$ On a price-to-earnings basis, the S&P 7 is now as overvalued as tech in 2000 and the Nifty Fifty in 1972.
These are the same stocks that have accounted for 95% of the S&P 500's gain this year.
The P/E ratio on some components of the S&P 7 is now more than DOUBLE the levels seen in previous bubbles.
For example, Nvidia, $NVIDIA(NVDA.US)$ , now has a P/E ratio of 115x.
However, without these 7 companies, the S&P 500 is up just 4% this year.

$Meta Platforms(META.US)$ $Amazon(AMZN.US)$ $Apple(AAPL.US)$ $Alphabet-C(GOOG.US)$ $Microsoft(MSFT.US)$ $Tesla(TSLA.US)$
Can these stocks continue to carry the entire market?
