US large cap market returns.

Notice

The week plot this time is for quite a long “week”.

Last week there were problems downloading the data.  There were still some this week, but the R code has been updated to be more useful in this event (it is no longer necessary to get all the data downloaded in one go).

Fine print

• The data are from Yahoo
• Almost all of the S&P 500 stocks are used
• The initial post was “Replacing market indices”
• The R code is in marketportrait_funs.R
