Historical Volatility Rolling Indexes: 2004 — 2014

Updated: Mar 10th, 2017 | Vance Harwood | @6_Figure_Invest

If your interests are related to the simulation / backtest of volatility exchange traded products like VXX and XIV, then you should review the products I have listed here.   While the indexes discussed in this post can be used to compute the prices of the volatility ETPs it is not an entirely straightforward process.

I have generated both the Excess Return (ER) and Total Returns (TR)  trading day values for the following rolling indexes of VIX volatility futures starting on March 26, 2004 through December 12, 2014.

  • Month 1-2 rolling indexes,  constant weighted average 1 month (Similar to SPVXSTR and SPVXSP)
  • Month 2-3 rolling indexes, constant weighted average 2 months
  • Month 3 -4 rolling indexes, constant weighted average 3 months
  • Month 4-5  rolling indexes, constant weighted average 4 months
  • Month 4-5-6-7 rolling indexes, constant weighted average 5 months (Similar to SPVXMTR and SPVXMP)  This is considered the “Mid term” maturity.

These indexes, or ones like them are required if you want to backtest various ETP products, or evaluate your own volatility strategy.

The algorithms for generating these indexes are documented in the prospectuses of volatility ETNs or ETFs.    Barclays’ VXX/VXZ fund prospectus is a good example.   See Volatility tickers for the current universe of volatility ETPs and their associated reference indexes.    The futures settlement data required for these index calculations is available on the CBOE website—in the form of 95+ separate spreadsheets.  To make the calculation of these indexes tractable I created a master spreadsheet  that integrates the futures settlement data into a single sheet.  See this post for more information about that spreadsheet.

These rolling indexes don’t exactly match the official indexes (SPVXSTR, SPVXSPSPVIX2MT, SPVIX3MT, SPVIX4MT, SPVXMP, and SPVXMTR), but when I compare my results to the values available on Bloomberg my results track within +-0.03% for the values I have sampled from December 2008 to December 2011  for each of the indexes.  See this readme file for more information on accuracy comparisons.  The official indexes start on December 20th, 2005, but I pushed them back to the beginning of VIX volatility futures trading which was in March 2004 by extrapolating mssing front month data.

These TR indexes do reflect the impact of 91 day treasury bills on their overall performance.   They are currently yielding a whopping .0031% on an annualized basis, but in February 2007 they were yielding over 5%— things have changed a bit…   The indexes do not include ETN fees, they vary from fund to fund, and aren’t included in the indexes themselves.

In working through the details of the algorithms there were no major surprises, but there were some subtleties—like discovering the market was closed on January 2, 2007 to commemorate President Reagan.   One significant detail is that the day-to-day rolling of the futures is done on a dollar weighted basis.  For example on the rolling 1 to 2 month index, if there are a total of 21 trading days in the current first month futures, it is not 1/21 of the contracts that are rolled over to the second month each day—it’s 1/21th of the dollar value of the index that is rolled over.  The reason for this distinction is that the goal of the index is to give a constant duration or maturity (e.g., 2 months),  if the roll amount isn’t dollar weighted then contango / backwardation would shift that duration one way or the other.

I am making these 5 indexes available for purchase, individually, or as a complete package.  If you cannot see purchase information immdediately below then please click this link to the stand-alone post and look at the bottom of the page.
