Option Program - BM• All positions established/closed monthly• Don’t try to guess market (Puts/Calls)• Take no assignments!• Buying power safety factor
– Has to be margin account
• Annual after-tax, STCG• Monthly proprietor draw (non-employee)• Balance remains to compound
– Could be invested in stock; Market risk if done so.
– Leave in for simulation purposes
14
Program Assumptions
• Tradeclock, centered at EOEXP– EOEXP / FDTM / EOM / EOY / BOY
• Establish positions in 1st 5 trading days
• Sell 1-Month, 1-OTM, 2-OTM
• Throw out trade if premium less than $100
• Throw out trade if a split is scheduled within the trading window
• The program does not handle blowouts
1515
Trading Program
• Parametric Trading Program– Opening premium distribution– Closing premium distribution

Parametric Program
• Parametric 1 – Fixed number of positions each month
• 1 position/day = 5 positions/month• 2 position/day = 10 positions/month
– Draw and tax rates 10%
• Parametric 2 – Number of portions determined by buying power– Upped tax rate to 25% at this stage; draw 10%
• Parametric 3– Actual trading position parameters– large trading losses
1717
Parametric 1
• Fixed number of positions; tax=10%, draw 10%. Open: lognormal; Close: Bernoulli/lognormal
• Cash only, A0=100,000
• Cash + Legacy Portfolio
• Cash + Legacy Portfolio, tax changed to 25% (kept the draw) and increased number of positions per month to 10 instead of 5.

Parametric 1 - Fixed
• Cash + Legacy Portfolio, tax changed to 25%; increased positions to 10 per month
• About the same graphs as with the 10% tax case.
• Same problem with decreasing returns.
• Nonetheless, $350,000 - $760,000 more than idle assets.
2222
Parametric 2
• Dynamic number of positions• Determined by buying power
• Positions consume buying power (a 10-lot $100 strike consumes $40,000 in BP)
• Open: lognormal; Close: Bernoulli/lognormal• Tax 25%, draw 10%

Resampling Approach
• Resampling using Trading Data
• Sample with replacement– Opening positions– Closing positions– No probability of expiration
• Summary(GAR.sim, M=6000) Min. 1st Qu. Median Mean 3rd Qu. Max.

BSOPM Program
• A necessary fiction
• Historical parameter estimation
• Implied volatility approximation
• How to handle splits (only 4/94 didn’t split)
• Results to be shown– Covered calls only– Uncovered fixed number of options– Covered calls and dynamic uncovered options

Covered Calls Only
• Same trading methodology
• DO NOT LOSE STOCK!
• Sell 1- or 2- strike OTM
• Only sell 1-month until expiration
• Cover on last trading day if ITM.
• Pretend never get called away – may really happen, even if OTM.– Real-life mitigation techniques

Uncovered options
• Compare selling 1-strike and 2-strike OTM • Compare fixed amount of symbols per day
for 5 days to establish– 1 symbol per day (up to 10 positions/month)– 10 symbols per day (up to 100 pos/mo.)– might have less
• Dynamic establish (based on buying power)– run out of stocks– results in multiple positions– Still realistic

• Bimodality of annual returns caused by winning and losing years
• Accumulated cash position key to program performance

Conclusions
• Idle assets have untapped buying power
• It is possible to sell time premium
• Hard to code trader’s skill/performance
• Resampling results show promising return
• BSOPM with approximations gives mixed results.– ITM vectors still not compensated for by
market prices, however
• Do not withdraw all the money!
6060
Future Work
• More Data– Spreads– Assignments
• Dynamic universe
• Historical option prices– Or better IV approximation– Not that far off
• Laddering of large positions
• Simulation of future results– many challenges
