This current concentration of high tech stocks, particularly the Magnificent Seven, is reminiscent of the early Seventies, Nifty Fifty. Unlike the 2000 Dot Com bubble where many of the overvaluations were companies with no earnings and many with lttle revenue, the Nifty Fifty were solid blue chip companies including IBM, Xerox, Eastman Kodak, Polaroid etc. that had earnings but the PE’s got to 50 or 100. Great, established successful companies that were never going to go down. Until they did. This is very similar, fifty years later. Most of the MAG 7 look like they have topped out. One or two, like MSFT, could still go a bit higher. Once the calendar rolls into 2024, much like what happened as soon as we moved from 2021 into 2022, those high tech overvalued NASDAQ 100 stocks (especially the Mag 7) are going to come down dramatically and probably for most, if not all of 2024. (This is not investment advice, just my opinion.) https://www.zerohedge.com/markets/tech-rally-sees-it-grab-ever-greater-share-sp-500
