(PUTR)
THE CBOE RUSSELL 2000 PutWrite Index (PUTR)
Introduction:
The CBOE RUSSELL 2000 PutWrite Index (PUTRSM Index) is designed to track the performance of a hypothetical
passive investment strategy that collects option premiums from writing an At-the-Money (ATM) RUT Put option on a
monthly basis and holds a rolling money market account invested in one-month T-bills to cover the liability from the
short RUT Put option position.
Index Design:
On January 19, 2001, the initial roll date of the PUTR Index, an ATM monthly RUT Put option is written. At the same
time, $K cash is invested in a money market account to cover the liability of the short RUT Put option position, where
K is the strike price of the RUT Put option.
The strike of the ATM RUT Put option is the first available strike below the last disseminated value of the Russell
2000® Index before 11:00 am ET. The premium collected from writing the RUT Put option is the volume weighted
average trade price between 11:30 am and 12:00 pm ET (VWAP). CBOE calculates the VWAP in two steps: first,
CBOE excludes trades in the new RUT Put option between 11:30 am and 12:00 pm ET that are identified as having
been executed as part of a “spread”; and second, CBOE calculates the weighted average of all remaining transaction
prices of the new RUT Put option between 11:30 am and 12:00 pm ET, with weights equal to the fraction of total nonspread volume transacted at each price during this period. If there is no trade in the RUT Put option during the VWAP
period, the last bid quote of the RUT Put option before 12:00 pm ET is used.
Typically, on the third Friday (Roll Day) of every month since the initial roll date, the RUT Put option settles and the
money market account is liquidated simultaneously. Subsequently, a new monthly ATM RUT Put is written. Following
the same rule as the initial roll date, the strike of the new RUT Put option would be the first available strike below the
last disseminated value of the Russell 2000 Index before 11:00 am ET. The premium collected from the RUT Put
option would be the VWAP between 11:30 am and 12:00 pm ET, or the last bid quote of the RUT Put option before
12:00 am ET if there is no trade during the VWAP period. A money market account with initial cash $K, where K is
the strike price of the new RUT Put option, is set up simultaneously to cover the potential liability of the short RUT
Put option position. The money market account will accumulate interest at one-month T-bill rate.
Index Calculation:
The PUTR Index value is calculated by CBOE in real-time, every 15 seconds.
On each trading day excluding roll dates, the daily return of the index is calculated as:
R t = (M t – Put t) / (M t-1 – Put t-1)
M t= Rf *M t-1
Where Mt and Mt-1 are the values of the money market account on day t and t-1, respectively, Rf is the one-month T-bill
rate de-annualized to the daily rate, Put t is the average of the last bid-ask quote of the RUT Put option before 4:00 pm
ET, and Put t-1 is the average of the last bid-ask quote of the RUT Put option before 4:00 pm ET on the previous day.
On Roll Days, the calculations are as follows:
First, calculate the return from the previous day market close to morning settlement (9:30 am ET):
R1 = (M_old t-1 – Put_old settle) / (M_old t-1 – Put_old t-1)
Where Put_old settle = Max (0, K old – SOQ t) is the settlement value of the expiring RUT Put option, Put_old t-1 is the
average of the last bid-ask quote of the expiring RUT Put option before 4:00 pm ET on the previous day, and M_old t-1
is the value of the money market account on the previous day. Note interest is not accumulated in the money market
account on the Roll Day.

Second, calculate the return from the moment the new RUT Put option is deemed sold to market close:
R2 = (M_new t – Put_new t) / (M_new t – Put_new vwap)
Where M_new t = K new is the cash allocated to cover the potential loss of the new RUT Put option on the Roll Day,
Put_new t is the average of the last bid-ask quote of the new RUT Put option before 4:00 pm ET, and Put_new vwap is
the VWAP price of the new ATM RUT Put option. Note interest is not accumulated in the money market account on
the Roll Day.
The product of the two parts is the total return of the Roll Day:
R t = R1 * R 2
Once the daily return is calculated for every trading day, the daily index value is calculated as:
INDEX t = INDEX t-1 * R t
