Subject: 200 Days of SPY vs BRK
Just for fun...and to illustrate the meaninglessness of short-term charting.

The Stockcharts link I use defaults to 200 trading days (a year is 252).

The 200-day SPY vs BRK/B is a bit shocking right now:

40% difference in return!

Change the chart to 6,800 days to feel better:
