Sell Put Spread Strategy on SPY To Generate Monthly Income

 



I was introduced into the world of Options Trading when I joined a Value Investing Course by a stock investing guru named Sean Seah. One was the strategies I learned from this course is called VIOS (Value Investing Option Strategy). This strategy aims to consistently make money by selling naked put options to collect premiums on fundamentally good stocks with minimal risk (worst case scenario you are forced to buy that stock if your option is exercised). Anyway I won't be talking too much about the Fundamentals of Options as you can find many free videos of these on YouTube and paid courses on Udemy.


I have been selling mostly naked put options to collect premium for 4 years using the ThinkOrSwim platform and I was collecting good premiums making some small profit. One strategy I used was to keep rolling my option if it went In-The-Money (ITM) on expiration day . However I discovered that  there is a huge risk involved with this Naked Selling Option Strategy even when trading fundamentally strong stock.  I was faced with some Hard Truths, that the stock market can be very volatile, unpredictable and it is possible to lose a lot of money.


During the US Stock market crash back in February/March of 2020, I sold a naked put option on Coke (ticker: KO) at $60 to collect a premium of USD30.00. Within a month, the price of KO went from $60 to $35, and my naked option was exercised since it was deep in-the-money (ITM), where I was forced to buy KO at $60 even though the price went all the way down to $35. So from earning a premium of USD30, I was looking at a loss of USD2500!  I was not even able to roll my option any longer as well since it was too deep ITM. From that time onwards I have mostly changed from selling naked options to selling vertical put spread. 


Recently I came across this Youtube video by projectoption which talks about selling vertical put spread on SPY to collect premiums. Here is the video:




This is a Sell Put Spread Strategy on SPY (SPDR S&P 500 ETF Trust) to collect premiums on a monthly basis. Here is a summary of the trading plan for this strategy :

Trade Entry Rule : 
VIX Below 30. If VIX is above 30, do not trade that month.

Trade Entry Date:
Open on the first trading day of the month (for me it can be within the first 3 trading days of the month - depends on VIX) 


Target Expiration :
Following month's standard monthly expiration (usually third Friday of the following month)

Target Expiration Examples:
Entry on the 1st Trading Day of January : February Monthly Expiration is Used (eg see below for the screenshot of the Option Chain as an example)

Target Expiration Option Chain :
Under PUT, SELL an option at Delta 30
Under PUT, BUY at Delta 16 (Strike Price is lower)

Take Profit and Stop Loss orders (you can use OCO advanced orders). 
Profit Target : 75% (eg if you collect a premium of 1.51, then place a Limit Order at around 0.38)
Stop Loss : -150% (eg if you collect a premium of 1.51, then place a Stop Order's at around 3.78)

Trade Exit Rules : 
Close your trade on the last trading day of the month (approximately 30 days of holding periods.) For instance, if my entry Date is Jan 2nd, 2020, then the last trading day of that month is Jan 31 2020. No matter what happens, I will close my January trade on Jan 31 2020 manually (if it is still open).



Make sure to watch the above video by projectoption as he shows the reasoning behind the rules, trade size and a detailed back testing result.

I did some back testing of my own (for the year 2020 only) using ThinkOrSwim OnDemand feature. I tried using both 150% and 100% Stop Loss. There were a few months that had huge drawdowns (particularly during the March 2020 Covid crash) but after 12 months, for both scenarios still ended up in profit.

Here is my the back test result with a Stop Loss set at 100% :



I have decided to follow this strategy and I currently have an option position which I opened on Jan 4th 2021. I plan update annually my progress with my result to check if this Strategy works over the long run.



Update : I have a guide on how to set OCO (Order-Cancels-Order) in ThinkOrSwim. Click here to check it out.

A Study in Technical Analysis : Candlestick Part 1 - One White Soldier

Decided to start a Technical Analysis series to analyze a few candlestick patterns and other tools to help me improve my stock and options trading.  ONE WHITE SOLDIER One White Soldier candlestick pattern is a Bullish Reversal Pattern used to predict the reversal of the current downtrend. The pattern consists of two consecutive long-bodied candlesticks - The first being a Bearish Candlestick followed by a Bullish Candlestick. This candlestick pattern rarely appears and if it does appear it's likely a strong indication of a reversal in trend (supported by other indicators as well). The One White Soldier should have the following  characteristics.  Bearish Candle followed by a Bullish Candle.  If it is during a long downtrend, The Bearish Candle must be a new low in the downtrend(Counter Trend Trade).   1.   The Bullish Candle must open Above the Close of the Bearish Candle Open2 Higher than Close1   ...

What are the Different Levels of FiRe ?

FiRe (Financial Independence / Retire Early)  is a movement where a person has to adopt to a certain lifestyle with the goal of gaining Financial Independence and Retiring Early. I only got to know of this movement a few years ago after watching a video on Graham Stephen's Youtube channel.  Just like Graham Stephen, I started adapting a frugal and savings lifestyle when I was young but there wasn't a name for this until  Fi/Re  was made famous. I got serious about Saving To Retire Early about 10 years ago after attending T Harv Eker's Millionaire Mindset seminar . I learned about the JAR system from the seminar and I have been practicing it without fail for the past 10 years. I am proud to say this has helped me tremendously to achieve my financial freedom goal. T Harv Eker has a book called " Secrets of the Millionaire Mind: Mastering the Inner Game of Wealth " which I highly recommend.  I wrote an article about the Money JAR System which you can read by c lic...

Trading Journey [ Part 2 ] - Consistent Set of Actions

The month of March2021 had been a rather rough month for me. I lost 100% in my Sell Put strategy for SPY due to the crazy volatility caused by the 10 year yield scare. I have since adjusted my Stop Loss to be triggered at 250% instead to avoid being stopped out from price volatility. I closed my PEPSI sell put option by manual cut loss 21 days before  expiration which ended up bring profitable if I didn't cut early...another reason to stick with the original game plan instead of tweaking my exit plan halfway after entering the trade. I just realized 100% losses from my bull put strategy on APPLE and JNJ.   The losses was a bit hard to take and do I decided to take more risks by not sticking with my game plan for my overall trading strategy and added more options trades which did not follow my rules and went beyond my trading size. Once such trade is I did a SELL Iron Condor on Facebook when it was trading at $260. I looked at the chart and saw it was in middle a strong Re...
