Attention Math Nerds

Here’s a spreadsheet of some multiple regressions I ran.
I looked at the daily changes of the 10 S&P industry groups against each other. The regressions are the columns not the rows. (I’m afraid I’m out of my depth mathematically, so if anything looks off, please let me know.)
Healthcare and Staples seem to be strongly related. I like to think of them as subsets of one large group called Defensives. Also, Energy and Materials are strongly related. I was surprised to see such a strong connection between Financials and Consumer Discretionary stocks.
