If you're wondering just how unusual this year has been, here's yet another way to look at it. TWENTY THREE S&P 500 stocks have increased 100%+ this year. That's by far the highest number for at least the past FORTY years (maybe all-time). The stocks that have doubled have contributed roughly 5-6% of the overall 8% gain YTD for the S&P 500. It is highly unusual for an S&P 500 stock to double. In most years, there are at most a few stocks that double. Of course the last time we saw a surge in the number of S&P 500 stocks that doubled was in 1999..... History suggests this type of unrelenting bid will not be sustained. As you look at the list below, you'll notice the only non-AI/semis/data center stock in the S&P 500 that has doubled is $MRNA, which was down (-90%+) from its COVID19 highs. If you're looking for doubles or 10-baggers going forward, perhaps it's time to look outside of the data center trade... $SNDK $WDC $STX $MU $INTC $DELL $MRVL $FLEX $AMD $AMAT $LITE $GLW $LRCX $TER $ON $COHR $MRNA $FIX $HPE $GNRC $KLAC $Q
