Indian Movie Industry(combination of Bollywood, Tollywood, Mollywood and few other woods) is among the most vibrant content creator industries serving to a very smart and astute customer. The Indian movie fans take the movie business very seriously. Its a very competitive field both for the artists and actors as well as the production houses, the directors and cinema halls. With a very short shelf life, movies are a very interesting and extremely fast paced product. Of course this makes movies a market of choice for lot of studies and when mega events happen, we watch them closely.
One such event is happening on April 28th with release of the concluding part of the 2015 mega period blockbuster movie Bahubali.
Ever since its release in 2015, the word Baahubali (meaning the liberated soul with strong arms) is used in everyday conversation to emphasize greatness. It is a classic David vs. Goliath story. There are even a number of jokes and whatsapp forwards going around over why Katappa, one of the loyal slaves of the protagonist Bahubali kill his master as was left shown – but reason untold – in the first version. The conclusion part will answer this question. When such events happen, the whole society is on a lookout.
Now stock markets are no exception to such events. After all, behind all the algorithms and terminals, it is the human being operating them. People feel good when there are such mega events happening, just as sorrow and fear grips the markets when any bad news arrives. There is euphoria with what we call as the ‘Adrenaline Rush’.
So what is Adrenaline Rush?
As per my own study from various sources, during adrenaline rush along with secretion of more hormones, there is a spike in the blood pressure. This is to support the brain’s need to move the blood from frontal lobe (the one that takes long term analytical decisions) to the motor cortex, the part of brain that pushes us to take action immediately. It is this redistribution of blood that leads us to take action. This biochemical sequence leading to ‘rash decisions’ is of interest to us.
My keen interest in both the fields of movie industry and trading, led me to do some quick analysis of SENSEX and specifically the NIFTY Media index to see the impact of such mega releases to the markets. The data sets I used are following:
- List of all hit movies from 2011 to 2016
- Sensex performance on the day of release of a particular movie
- NIFTY Media Index performance from August 2011 (could not find data for dates before that).
- Collected data for All Major blockbusters from 2011. Below is the list of all the major blockbusters in the consideration set. Here is the list of all the movies used for the consideration set. Bahubali Analysis Data Set
- To see any apparent patterns, I plotted the historical data for visual inspection
- Next, the’Expected Value’ of the ‘On the day of Release’ changes in SENSEX were determined. For Expected Value, the following was done:
- Continuous random variable over range of SENSEX movement on the day of release
- Computing Probability Distribution of the SENSEX change on the day
- Computing the Expected Value with a caveat that this is a solitary event. Expected values work better with long term ranges and multiple future data points. This was done here only for 1 instance.
- For NIFTY Media Index, following was done:
- Collected data of percentage changes for NIFTY Media Index on day of release
- Plotted the NIFTY media Data and built correlation with Blockbuster movies from the last 5 years
The fundamental assumption of this study is that Bahubali 2 would be blockbuster. The movie has already raked up more than its production cost, even before the release.
Bahubali and the NIFTY Media Index
The NIFTY Media Index is barometer of performance comprising of select Media stocks. Below is a snapshot of the NIFTY Media Index.
|Den Networks||Media & Entertainment||98.75||-0.20||-0.20||1,916.01|
|Eros Intl||Media & Entertainment||252.45||-3.05||-1.19||2,366.23|
|INOX Leisure||Media & Entertainment||297.55||4.80||1.64||2,870.10|
|JagranPrakashan||Media & Entertainment||191.95||-6.70||-3.37||6,275.07|
|Network 18||Finance – General||45.50||3.95||9.51||4,763.62|
|PVR||Media & Entertainment||1,555.85||-3.10||-0.20||7,271.82|
|Siti Networks||Media & Entertainment||37.90||0.05||0.13||3,305.08|
|Sun TV Network||Media & Entertainment||936.75||39.55||4.41||36,915.88|

|Zee Entertain||Media & Entertainment||528.60||-4.85||-0.91||50,769.32|
As is clear most of the stocks in this are media related. There is going to be a direct impact of Bahubali 2 box-office performance on movie distribution stocks like PVR. Also, the media rights provided to various channels have a bearing from the outcome of the movie’s performance.
The average drop in NIFTY Media Index is 0.04% on the day of release of the blockbusters in the past. This can be explained with the fact that most of the times, the growth and gains in this index are already made in the run up to the movie in the preceding weeks. So, while the movie is being released, there is a marginal change in the index.
- Unfortunately, the average bias on this marginal change is also negative with maximum loss of 3.29%, as was seen with the release of Rowdy Rathore.
- The maximum gain possible in this index as was seen on the day of release of Bodyguard and Dirty Picture is in the range of 2.20%.
- It is clear from the chart above that the NIFTY Media Index is making more losses than gains on the movie release day, though the frequency of losses is lower than the gains.
- One just hopes that the gains are there in the same magnitude as Bodyguard and The Dirty Picture i.e. > 2.00%.
Expected Value Calculation of Sensex
We identify Bahubali as a blockbuster movie i.e. it is going to rake up collections of more than Rs. 100 Crore (Rs. 1 Billion). This makes it part of an elite group of movies such as PK, Dangal, 3 Idiots, Dhoom etc.
Sensex on the other hand does not paint a very rosy picture on the day of release for these mega movies. About 60% of these movies have led to losses on Sensex on the day of release, with movies like ‘Yeh Jawaani Hai Deewani‘ seeing a SENSEX loss of 2.16% on their release day.
About 60% of these movies have led to losses on Sensex on the day of release
If the above patterns continue, SENSEX is expected to dip on the day of the release of Bahubali. What we have further tried to assess here is the probable drop that we can expect on the day of release.
To do this, the data has been arranged in a Continuous Random Variable for all the mega releases for the period of 2011-2016.
|MOVIE||CHANGE IN SENSEX|
|Prem Ratan Dhan Payo||-114|
|Happy New Year||-207|
|Ek Tha Tiger||-95|
|Yeh Jawaani Hai Deewani||-426|
|Tanu Weds Manu Returns||108|
|M S Doni – The Untold Story||58|
|Jab Tak Hai Jaan||-110|
|Ae Dil Hai Mushkil||-42|
|Bhaag Milkha Bhaag||208|
|Son of Sardaar||-110|
|Singh is Bliing||406|
|Zindagi Na Milegi Dobara||-132|
|Gabbar is back||-231|
|The Dirty Picture||353|
|Humpty Sharma Ki Dulhania||-465|
|Mere Brother Ki Dulhan||-323|

Given the Random nature of the SENSEX change values on the day of release of these mega movies, these were grouped together in 100 point intervals for Continuous Random Variables with the range starting from -500 and going all the way to +500.
Consequently, probability distribution as given below was prepared
Some highlights from the above distribution chart:
- The SENSEX changes have maximum density in the -99 to 0 range.
- The SENSEX never gained more than 500 points but it lost more than 500 points at least once.
- The probability of big sways are low while the chances of reasonable sway are very high in the distribution.
Next, the Expected Value of SENSEX change was calculated as below:
Expected Value = x1*Probability of x1 + x2*Probability of x2 + x3*Probability of x3….
So Our Expected Value Formulation Looks like this:
|Sensex Change||Probability||Range High||Range Low||Mean Value||xi*p(xi)|
Given this, the Expected Value of SENSEX on release day of Bahubali is -17.39.
While this may not be true as this is just a Probabilistic Model for Expected Value of Sensex Movement on day of release, it is surely something to watch out for.
More importantly, as the trend suggests, the mega blockbuster movies actually DO NOT pump adrenaline rush into the system, with more people taking risk. On the contrary, it leads to normal Epinephrine. In contrast to the rush, normal Epinephrine does exactly the opposite, it smooths body and brain during the activity and saves us from taking any rash decisions.
Happy watching and happy trading 🙂
UPDATE 1: The markets spooked by over 100 points in opening trade.
1 thought on “Would Bahubali spill Blood on D-Street? This Probabilistic Model says so…”
[…] The year 2017 also saw the release of Bahubali 2, The magnum opus from the Indian movie industry for a long time. It made me wonder if the stock markets had any interest in such mega releases. My naivete had me probe whether such movies have any behavioral impact on the stock markets, essentially algorithmic trades designed by humans. This study was another interesting exercise but unfortunately, did not give any indication of human desire for entertainment and the greed to earn more money. Here is the full study. […]
