The document describes the CBOE Volatility Index (VIX), which measures the market's expectation of 30-day volatility implied by S&P 500 index option prices. It discusses how VIX was updated in 2003 to be based on the S&P 500 using a new methodology, and how this transformed VIX into a tradable asset with the introduction of VIX futures and options. The document also provides details on how VIX is calculated using a formula that averages weighted option prices over a range of strike prices.

In 1993, the Chicago Board Options Exchange速
(CBOE速
) introduced the CBOE Volatility
Index速
, VIX速
, which was originally designed to measure the markets expectation of 30-
day volatility implied by at-the-money S&P 100速
Index (OEX速
) option prices. VIX soon
became the premier benchmark for U.S. stock market volatility. It is regularly featured in
the Wall Street Journal, Barrons and other leading financial publications, as well as
business news shows on CNBC, Bloomberg TV and CNN/Money, where VIX is often
referred to as the fear index.
Ten years later in 2003, CBOE together with Goldman Sachs, updated the VIX to reflect a
new way to measure expected volatility, one that continues to be widely used by financial
theorists, risk managers and volatility traders alike. The new VIX is based on the S&P
500速
Index (SPXSM
), the core index for U.S. equities, and estimates expected volatility by
averaging the weighted prices of SPX puts and calls over a wide range of strike prices. By
supplying a script for replicating volatility exposure with a portfolio of SPX options, this
new methodology transformed VIX from an abstract concept into a practical standard for
trading and hedging volatility.

On March 24, 2004, CBOE introduced the first exchange-traded VIX futures contract on
its new, all-electronic CBOE Futures ExchangeSM
(CFE速
). Two years later in February
2006, CBOE launched VIX options, the most successful new product in Exchange history.
In less than five years, the combined trading activity in VIX options and futures has grown
to more than 100,000 contracts per day.
The negative correlation of volatility to stock market returns is well documented and
suggests a diversification benefit to including volatility in an investment portfolio. VIX
futures and options are designed to deliver pure volatility exposure in a single, efficient
package. CBOE/CFE provides a continuous, liquid and transparent market for VIX
products that are available to all investors from the smallest retail trader to the largest
institutional money managers and hedge funds.

In addition to VIX, CBOE calculates several other volatility indexes including the CBOE
Nasdaq-100速
Volatility Index (VXNSM
), CBOE DJIA速
Volatility Index (VXDSM
), CBOE
Russell 2000速
Volatility Index (RVXSM
) and CBOE S&P 500速

(VXVSM
). Currently, VXD and RVX futures are listed on CFE; RVX options trade on
CBOE.
In 2008, CBOE pioneered the use of the VIX methodology to estimate expected volatility
of certain commodities and foreign currencies. The CBOE Crude Oil Volatility Index

HISTORICAL PRICES FOR VIX AND OTHER VOLATILITY INDEXES
Perhaps one of the most valuable features of VIX is the existence of more than 20 years of
historical prices. This extensive data set provides investors with a useful perspective of
how option prices have behaved in response to a variety of market conditions. Price
history for the original CBOE Volatility Index (Ticker VXO) based on OEX options is
available from 1986 to the present. CBOE has created a similar historical record for the
new VIX dating back to 1990 so that investors can compare the new VIX with VXO,
which reflects information about the volatility skew or smile. Historical prices for
VIX, VXO and CBOEs other volatility indexes may be found on the CBOE website at
http://www.cboe.com/micro/IndexSites.aspx under CBOE Volatility Indexes.
CBOE would like to thank Sandy Rattray and Devesh Shah for their
significant contributions to the development of the New VIX calculation.

GGGGETTINGETTINGETTINGETTING SSSSTARTEDTARTEDTARTEDTARTED
VIX measures 30-day expected volatility of the S&P 500 Index. The components of VIX
are near- and next-term put and call options, usually in the first and second SPX contract
months. Near-term options must have at least one week to expiration; a requirement
intended to minimize pricing anomalies that might occur close to expiration. When the
near-term options have less than a week to expiration, VIX rolls to the second and third
SPX contract months. For example, on the second Friday in June, VIX would be
calculated using SPX options expiring in June and July. On the following Monday, July
would replace June as the near-term and August would replace July as the next-term.
In this hypothetical example, the near-term and next-term options have 9 days and 37 days
to expiration, respectively, and reflect prices observed at the open of trading 8:30 a.m.
Chicago time. For the purpose of calculating time to expiration, SPX options are deemed
to expire at the open of trading on SPX settlement day - the third Friday of the month1
.
The VIX calculation measures time to expiration, T, in calendar days and divides each day
into minutes in order to replicate the precision that is commonly used by professional
option and volatility traders. The time to expiration is given by the following expression:
T = {MCurrent day + MSettlement day + MOther days}/ Minutes in a year
WWWWHEREHEREHEREHERE
MCurrent day = minutes remaining until midnight of the current day
MSettlement day = minutes from midnight until 8:30 a.m. on SPX settlement day
MOther days = total minutes in the days between current day and settlement day
Using 8:30 a.m. as the time of the calculation, T for the near-term and next-term options,
T1 and T2, respectively, is:
T1 = {930 + 510 + 11,520) / 525,600 = 0.0246575
T2 = {930 + 510 + 51,840) / 525,600 = 0.1013699
The risk-free interest rate, R, is the bond-equivalent yield of the U.S. T-bill maturing
closest to the expiration dates of relevant SPX options. As such, the VIX calculation may
use different risk-free interest rates for near- and next-term options. In this example,
however, assume that R = 0.38% for both sets of options.
Since many of the interim calculations are repetitive, only representative samples appear
below. The complete set of SPX option data and calculations may be found in Appendix 1.
1
Technically, the expiration date for SPX options is the Saturday following the third Friday of the
expiration month. In this example, however, expiration is deemed to take place at the determination of the
exercise settlement value of the SPX, which is based on the opening prices of SPX component securities.

SSSSTEPTEPTEPTEP 1111 Select the options to be used in the VIX calculation
The selected options are out-of-the-money SPX calls and out-of-the-money SPX puts
centered around an at-the-money strike price, K0. Only SPX options quoted with non-zero
bid prices are used in the VIX calculation.
One important note: as volatility rises and falls, the strike price range of options with non-
zero bids tends to expand and contract. As a result, the number of options used in the VIX
calculation may vary from month-to-month, day-to-day and possibly, even minute-to-
minute.
For each contract month:
Determine the forward SPX level, F, by identifying the strike price at which the
absolute difference between the call and put prices is smallest. The call and put
prices in the following table reflect the average of each options bid / ask quotation.
As shown below, the difference between the call and put prices is smallest at the
920 strike for both the near- and next-term options.

. . . . . . . .
Using the 920 call and put in each contract month and the formula,
F = Strike Price + eRT
(Call Price Put Price),
the forward index prices, F1 and F2, for the near- and next-term options, respectively,
are:
F1 = 920 + e(0.0038 0.0246575)
(37.15 36.65) = 920.50005
F2 = 920 + e(0.0038 0.1013699)
(61.55 60.55) = 921.00039
Next, determine K0 - the strike price immediately below the forward index level, F
- for the near- and next-term options. In this example, K0,1 = 920 and K0,2 = 920.

Select out-of-the-money put options with strike prices < K0. Start with the put
strike immediately lower than K0 and move to successively lower strike prices.
Exclude any put option that has a bid price equal to zero (i.e., no bid). As shown
below, once two puts with consecutive strike prices are found to have zero bid
prices, no puts with lower strikes are considered for inclusion.

VIX is an amalgam of the information reflected in the prices of all of the selected options.
The contribution of a single option to the VIX value is proportional to K and the price of
that option, and inversely proportional to the square of the options strike price.
Generally, Ki is half the difference between the strike prices on either side of Ki. For
example, the K for the next-term 300 Put is 75: K300 Put = (350 200)/2. At the upper
and lower edges of any given strip of options, Ki is simply the difference between Ki and
the adjacent strike price. In this example, the 400 Put is the lowest strike in the strip of
near-term options and 425 is the adjacent strike. Therefore, K400 Put = 25 (i.e., 425 400).

When the near-term options have less than 30 days to expiration and the next-term options
have more than 30 days to expiration, the resulting VIX value reflects an interpolation of
2
1 and 2
2 ;i.e., each individual weight is less than or equal to 1 and the sum of the
weights equals 1.
At the time of the VIX roll, both the near-term and next-term options have more than 30
days to expiration. The same formula is used to calculate the 30-day weighted average, but
the result is an extrapolation of 2
1 and 2
2 ;i.e., the sum of the weights is still 1, but the
near-term weight is greater than 1 and the next-term weight is negative (e.g., 1.25 and
0.25).
Returning to the example
NT1 = number of minutes to settlement of the near-term options (12,960)
NT2 = number of minutes to settlement of the next-term options (53,280)
N30 = number of minutes in 30 days (30 1,440 = 43,200)
N365 = number of minutes in a 365-day year (365 1,440 = 525,600)

CBOE calculates volatility indexes on three other broad-based indexes representing
different segments of the U.S. stock market:
CBOE DJIA Volatility Index (VXD) based on options on the Dow Jones Industrial
Average (DJX);
CBOE Nasdaq-100 Volatility Index (VXN) based on Nasdaq-100 Index (NDX)
options; and
CBOE Russell 2000 Volatility Index (RVX) based on Russell 2000 Index (RUT)
options.
For each of these indexes, the selection of component options and calculation are identical
to the method detailed in the previous example.
The CBOE S&P 500 3-Month Volatility Index (VXV) measures the market's expectation
of 3-month volatility implied by SPX options that bracket a 93-day maturity. Comparing

CBOE began calculating two commodity volatility indexes and one currency volatility
index in 2008:
CBOE Crude Oil Volatility Index (OVX) based on United States Oil Fund, LP
(USO) options;
CBOE Gold Volatility Index (GVZ) based on the, SPDR Gold Shares (GLD)
options; and
CBOE EuroCurrency Volatility Index (EVZ) based on CurrencyShares Euro Trust
(FXE) options
Each of these non-equity volatility indexes are calculated using exchange traded fund, or
ETF, options that trade like options on individual stocks - they may be exercised prior to
their expiration date; exercise results in the delivery of ETF shares rather than cash; and
they settle at the close of trading rather than at the open.
For each of the non-equity volatility indexes, the method of selecting component options
and the formula are identical to that used for VIX and other broad-based volatility indexes.
However, there is a slight difference in the methodology that accounts for the fact that
USO, GLD and FXE options expire at the close rather than at the open. As before, the
time to expiration is given by the following expression:
T = {MCurrent day + MSettlement day + MOther days}/ Minutes in a year

MCurrent day = minutes remaining until midnight of the current day
MOther days = total minutes in the days between current day and settlement day
But now, adjusting for p.m. settlement
MSettlement day = minutes from midnight until 3:00 p.m. on expiration day
= 900 minutes
As with the previous example, assuming near- and next-term options with 9 and 37 days to
expiration and 8:30 a.m. as the time of the calculation, T for the near-term and next-term
options, T1 and T2, respectively, is:
T1 = {930 + 900 + 11,520) / 525,600 = 0.0253995
T2 = {930 + 900 + 51,840) / 525,600 = 0.1021118
Special Note: All CBOE Volatility Indexes VIX, VXD, VXN, RVX, VXV, OVX, GVZ
and EVZ are calculated using option price quotes from CBOE exclusively.
