SMI Data – 141 Days in Winter 2011/2012

Description

SMI.12 contains the close prices of all 20 constituents of the Swiss Market Index (SMI) from 2011-09-09 to 2012-03-28.

Usage

data(SMI.12)

Format

SMI.12 is conceptually a multivariate time series, here simply stored as numeric matrix, where the rownames are dates (of week days).

The format is:

num [1:141, 1:20] 16.1 15.7 15.7 16.1 16.6 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:141] "2011-09-09" "2011-09-12" "2011-09-13" "2011-09-14" ... ..$ : chr [1:20] "ABBN" "ATLN" "ADEN" "CSGN" ...

... from 2011-09-09 to 2012-03-28

lSMI is the list of the original data (before NA “imputation”).

Source

The data was drawn from Yahoo! Finance.
