#' S&P 500 stock data
#'
#' Daily stock returns from the S&P500 for 1990-2011 can be used to assess
#' whether stock activity each day is independent of the stock's behavior on
#' previous days. We label each day as Up or Down (D) depending on whether the
#' market was up or down that day. For example, consider the following changes
#' in price, their new labels of up and down, and then the number of days that
#' must be observed before each Up day.
