optionm

This repository conducts buy- and sell- side analysis of call and put options on top 100 US firms by market cap. For a thorough introduction see the Wiki tab.

Warning:

This is an exploratory study with no profitable strategy in sight.
Provision of codes is not an investment advice.
All codes and analyses are subject to error.

Replication:

– In a terminal window install the requirements as:

pip install -r requirements.txt

– In Python environment import the OptionM module as:

from optionm_module import OptionM as om

You will be asked to enter your credentials for accessing WRDS at this stage.

– Specify the module using study_period and horizon as:

a=om(tudy_period=range(2001,now.year-1),horizon=91,progress=100)

Choices for horizon are [10, 30, 60, 91, 122, 152, 182, 273, 365, 547,730]

– Obtain the necessary OptionMetrics record matched with CRSP through:

a.step1_crsp()

– Process the data to generate different proxies of volatitlity matched with each record as:

a.step2_proc()

– Analyse the data for a buy-side analysis for top market_cap_count firms by market capitalisation as:

[result_tbl = ] a.analyse_buy(market_cap_count=100)

– Analyse the data for a sell-side analysis for top market_cap_count firms by market capitalisation as:

[result_tbl = ] a.analyse_sell(market_cap_count=100)

result_tbl is a record of all findings in buy/sell side analysis as a DataFrame.

It is suggested that you replicate this process for different maturity periods (e.g. 30, 60, 91, 182, 365) to see the figures as in Wiki tab.

Dataset:

– The main chunk of data on option contract including details on premiums, implied volatility, and prices are from OptionMetrics.

– Market capitalisation information is obtained from CRSP. Only common stocks (Share Codes 10 and 11) listed in Exchange Codes 1 to 3 (NYSE and NASDAQ) are considered.

– Matching OptionMetric data with CRSP is done through 8-character CUSIP code from CUSIP Global Services.

All datasets are accessed through WRDS

Access requirement:

To access and replicate the results you need an active subscription with WRDS. Specifically, you need active subscriptions to OptionMetrics, CUSIP, and CRSP libraries on WRDS.
