Reminded of the Tied Test in Chennai

I started watching the ongoing Test match just after tea, with the score at 210/2 or something. And the resemblances with *that* Test match in Chennai in 1986 were striking.

1. Australia declared twice in both games. In both games they declared after losing 7 wickets in the first innings and 5 wickets in the second.

2. Overnight declaration on day 4, leaving India to score at approximately 4 an over on the last day

3. Good finger spinners – Lyon here, Bright and Matthews there.

4. Three hundreds for Australia in the first innings – Boon, Border and Jones there; Clarke, Smith and Warner here

Ok there was no Virat Kohli like innings but it seems like he’s combining the roles of Sunil Gavaskar (who scored 90) and Ravi Shastri (who led the final charge with 48*) here. Let’s see how it goes.

The pressure of chasing a target in One Day Internationals

I was looking at the average runs scored per over in One Day Internationals from 2009 onwards (data from cricsheet ). The data is presented in the graph below. What is striking is the difference in runs scored per over between the team batting first and second.

The  blue line shows the runs per over for the team batting first, and the red line for the team batting second. These figures are averaged over all ODIs from 2009 till the end of the recent Asia Cup. What you will notice is that the way you score runs in the first and second innings is different.

For the first part of the innings, till almost over 35, the team batting second scores much faster than the team batting first. Then somewhere around over 40, the two lines cross, And then the blue line pulls away from the red one – and really fast.

In the last over of the innings, for example, the team batting first is expected to score ten runs, while the team batting second is expected to score only eight and a half. In the forty fifth over, the team batting first scores seven runs on an average, while the chasing team only scores six!

The difference in scoring patterns is striking, and the only possible explanation is the pressure of chasing! When you have a target in mind, and you are chasing, you are unable to bat as freely as you do when you are setting a target. Consequently, you are not able to score as many runs!

The next question is if there is a variation across teams. Given below is the same graph as above, but plotted by batting team.

The graphs are smaller, so the gaps aren’t too visible, but if you look for a gap between the blue and red lines by team, you will find that the biggest gaps are for India, New Zealand and Australia! Sri Lanka and Pakistan seem to bat similarly, however, irrespective of whether they are setting a target or chasing!

 

 

Process

A couple of days back, I was debugging some code. And yes, for those of you who didn’t know, coding is a part of my job. I used to have this theory that whatever job you take, there is some part of it that is going to be boring. Or to put it in the immortal words of a brilliant co-intern at JP Morgan “chootiya kaam”. And in my job, the chootiya part of the kaam is coding. That doesn’t mean that I’m not enjoying it, though. In fact, for the first time in nine years (note that this takes me to a time before I’d started my BTech in Computer Science) I’m enjoying coding.

Coming back, I was debugging my code yesterday. It was one of those impossible bugs. One of those cases where you had no clue why things were going wrong. So I started off by looking at the log files. All clean, and no bugs located. While I was going through them, I got this idea that the strategy sheet might offer some clue as to why things aren’t doing well. Half the problem got diagnosed when I was looking at the strategy sheet. Some problem with cash management.

And when I thought looking at the trades might help. The bug was presently discovered. And then it hit me – that I’d unwittingly followed what seems like a “process”. Everything that I did had been guided by insight and instinct. Yet, the steps that I followed – 1. look at the logs; 2. look at the strategy sheet ; 3. look at the trades – seemed so much a preset process. It seemed to be like one of those things that I’d just ended up reading in some manual and following.

I realize that most “standard processes” that are followed by  various people in various places are stuff that were initially not meant to be processes. They were just an imprint of somone’s train of insights. It was as if someone had a series of insights that led to a solution to whta might have been a difficult problem. And then, he realized that this kind of a process could be followed to deal with all such similar problems. And so he wrote down the process in a book and taught a set of people to implement them. The field thus got “fighterized“.

The argument I’m trying to make here is that a large number of so-called “standard processes” are just an imprint of someone’s insight. They just happened to get into place because the inventor noticed this pattern in a bunch of things that he was doing. They need not be the best way of doing what is supposed to be done. Maybe there isn’t even a single best way of doing it that might work every time.

People who are likely to have worked on processes later in their life cycle are likely to have been people who are process-oriented themselves, and given how these kind of people work, it would have been likely that they would have resisted changes that could make the process worse in the short term. They are more likely to have been incremental in their approach. With a succession of such people working on improving the process, the process of refining the process would’ve ended up taking a hill-climbing algorithm and is likely to have ended up in a local maximum.

Once again, the large changes to the process would’ve happened when someone who was willing to take a large step backward worked on them, and it is again likely that such a person would be driven more by insight rather than by process.

My hypothesis is that most processes are likely to have been largely defined by people who are themselves not very process-oriented, and who thus will expect a certain level of insight and discretion on the part of the person implementing the process. And one needs to keep this in mind while following processes. That it would be good if one were to take a critical view of every process being used, and not be afraid to take a backward step or two in process development in order to achieve large-scale improvements.

Bloomberg Watching

Two weeks back we were all given dual screens at office. A couple of days after that, those of us that had joined recently got Bloomberg logins. It’s a very restricted version of Bloomberg, with most of the strong features having been disabled. One feature that is enabled, though, is to get the graph of the daily price movement of a security, or an index.

It is necessary to have hobbies at work. It is humanly impossible to concentrate solely on the work for all the eight or ten hours that you spend at office. You need distractions. However, in order to prevent yourself from being too distracted, it helps having one or two very strong distractions. Distractions which can crowd out all other distractions. They can be called “office hobbies”.

In the past, my office hobbies haven’t really been constructive. In my first job, I was part of a PJ Club, and we would exchange horrible jokes. By the time I got to my next job, I had been addicted to Orkut, and kept refreshing it to check if I’d gotten any new scraps. Of course, when there is a cricket match on, the Cricinfo screen makes for a good office hobby. In the last ten days, the World Chess Championship has served my evenings well. However, it is important to have a sustainable hobby which could also be constructive. One which might have a small chance of making impact on your work. And most importantly, it would be ideal if the boss doesn’t really disapprove of your office hobby.

For the last week and half at work, my right screen (remember that I have two screens) has been reserved for Bloomberg Watching. A Bloomberg window is open there in full size, and I would’ve usually put the daily movement graph of the Nifty there. And it updates real-time. It’s like a video game. I just sit and watch. And get fascinated by the kind of twists and turns that the markets take.

Twenty years back, I would spend my evenings in the courtyard of my grandfather’s house in Jayanagar watching ants move about. I would be fascinated by their random, yet orderly movements. I would spend hours together watching them.

Around the same time, I used to play another game. I used to splash water on the (red-oxide coated) walls of my loo, and watch the different streams of water flow down as i crapped. I would get fascinated by the patterns that the water droplets would form, the paths that they would take, the way they would suddenly change speed when they intersected, and so forth. I would end up squatting there long after I’d been done with my crap.

So what I’m doing now is not exactly new. I just watch a point move. Orderly from left to right. Wildly fluctuating in the up-down direction. I look at the patterns and try to guess which animal they look like, or which country they look like. I get fascinated by the sudden twists and turns that the curve takes, and wonder about the collective wisdom of all market participants who are faciliating such movement. I occasionally scream out to my colleagues saying stuff like “nifty below 2600!” and they respond with a “behenchod…” or some equivalent of it.

As the day wears on, I realized that some animals I had recognized earlier in the day are hardly visible now. They are but specks in the larger graph that is the day. And then I realize that unless there was something truly special, the movement of the day will also soon be lost. It will be available for download from the same Bloomberg terminal but that will be about it. And so forth.

Occasionally I catch some unsuspecting soul on my GTalk list and spout such philosophy. I tell them about how after a while everything becomes insignificant. About how we will always be just small players in the larger system. The smarter among them will add their own philosophy to mine, and sometimes we come up with a new theory. The not so smart among them – they will ask me about my views on the market. And what would be good picks (this has been a regular question I’ve been asked ever since I got back into the finance industry but more about that later). And then they say something like how terrorists are the reason the stock markets are plunging, and how the government should protect investors’ money and stuff.

Some day I hope all of this will be useful. Some day I hope my eye for recognizing animals and countries where none exist will enable me to come up with some earthshaking strategy, which can make millions for my fund. However, now that doesn’t matter. All that matters is the unbridled joy of watching the ticker move up and down. Rise and fall. Take baby steps, and the occasional giant leap. It’s surreal.
