The Stock Market Is Currently Out of Breadth But It's No Reason to Worry.. new from me on the latest worry being hurled at investors from the columnist class and what they aren't telling you: 1) over past 100 years only 4% of stocks generated all net US market-wealth creation w/ half of cos lagging treasuries = lack of breadth has always been a thing 2) The big cos doing all the heavy lifting are not normal big cos, they are like small countries- each of them having acquired hundreds of companies. Microsoft and Google have each acquired 270(!) companies. I don't think they enforce anti-trust laws anymore. So you have prob should think about the Mag 7 as the Mag 700. In that sense, there are hundreds of companies leading the 'breadthless' S&P 500 right now. Read the full note on BI ETF.
