The breadth of the advance continues to be impressive. Out of the 10 major S&P 500 sectors, the median one has more than 95% of its member stocks in an uptrend. That's the most in almost a decade.
Only about 1% of days over the past 30 years have seen participation this wide across sectors. Not only does the median sector have almost every one of its stocks in an uptrend, even the worst sector recently had more than 80% of its stocks above their 200-day moving averages.
It's rare to see even the worst laggard among sectors see such widespread uptrends among its stocks, occurring on about 2% of all days. Over the past 30 years, there have only been 23 days when the median sector had at least 95% of its members in uptrends, and even the worst sector had at least 75% participation.

Based on research we published last month, when the largest market cap stocks since the 1970s were added to the S&P 500, they had a strong tendency to see gains after the announcement date of their addition. But once they were actually added to the index, they showed a positive return over the next 3 months only 41% of the time, a caution sign for Tesla shareholders.

2. Tesla is also going to have one of the biggest market caps of any stock in the index. Or any stock, period. [Statista]
3. The stock is such a behemoth that it has burned short-sellers, and few have the derring-do to keep betting against it. [Goldman Sachs]
