For all option traders, whether naked call/put buyers or spread traders, the one thing that bothers them is the direction of the market, While this bother is true for all traders is it much more for option traders as the factor of time decay is built into the instrument. When a series expires on the last Thursday of the month, we all wonder what will be the fate of the next series. Should I buy Calls/Puts. Bull spread/Bear spread? What is my best chance of making a more certain
(higher probability) money?
It all depends on calling the direction right. AW10 has mentioned often that it is a 50:50 chance of calling the direction right. I just wanted to see if I could improve that. And here is what I discovered.
Here is the chart of NF as a series for the last 55 odd series. A series is different from a month. A month begins on 1st and ends on 30/31. A series begins on the day after expiry and ends on the last Thursday of the following month generally. As Future or Option Traders we are bothered about the series and not about the month but this distinction is generally lost.
Take a loot at the chart below
What does it tell you? It tells me the best estimate we can make of the next series is the performance of the current series.
Today is the best indicator of what may happen tomorrow. If the current series was bullish it is more likely that the next series will be bullish. So if the current series ended higher than its open, I am better off buying calls or Call Spreads than buying Puts or its cousins.
If we are looking for low risk trades then it is even more prudent to bet on a shorter move in the direction of the expired series. The shortest move based on Strike Prices available is 100.
So how good are my chances of reaching say 5000, if the current series closed at 4900 and had a bullish close? Based on data from January 2006 till July 2011, can you believe this, you would have got it 85% of the time!! Out of 55 series, 47 would have hit the 5000 mark!!.
Whereas if I had gone contra, that is buying Puts when the current series had ended bullishly, I would have hit the -100 Mark, only 70% of the time. This is only a broad indication. It does not say how much of negative adversion you would have to suffer to get that 100 but it still is a good bet to take.
The past performance is not a guarantee for Future performance but it shows us we do not have to buy options blindly.
