Today in the podcast, three big things you need to know: First, we looked at S&P 500 performance when market cap concentration in the biggest names has been high and in the 12-month period after fewer than 10% of stocks have been making new highs. Neither suggests concentration and narrow leadership are automatic sell signals. Second, Nasdaq valuations look stretched, but unlike the Tech bubble S&P 500 and Russell 2000 are well below recent peaks. Third, other things that jumped out from our indicators last week, which are constructive for stocks, include the strengthening earnings recovery, the continuation of favorable political tailwinds, and better trends in Small Caps.
