Another way to understand stock market risk is to examine how investors expect risk to evolve in the near future. The DJIA volatility index (FRED code: VXDCLS) is one such measure. Plot the level of this volatility index since October 1997 and as a second line, the percent change from a year ago of the S&P 500 index (FRED code: SP500). Compare their patterns. (Hint: Using the figure from Data Exploration question 1, select "Add Data Series" and input "VXDCLS" in the search box. Select "Copy to All Lines" to start the date range when

the volatility index becomes available (1997). Set the Units dropdown box to "Percent" (to show the volatility index level) and select "Redraw Graph.")
