Sachin Tendulkar - a Measure of Greatness

After 24 years of playing Test Match Cricket Sachin Tendulkar has finally retired. He leaves with many of the game’s career records. There is no doubt that he is one of the greatest batsmen to ever play the game of Test Cricket but how does his longevity stack up against another sports icon’s records?

The best comparison I can find in any other sport I follow is the NFL's Jerry Rice who retired in 2005 after 20 seasons playing in the NFL at the top level. NFL fans will point to the fact that there’s no reason to compare football and cricket because cricket is not as tough and physical as football. But every sport has its own set of challenges. And to compete in any sport you have to go against the best in that specific sport.
The only way to measure greatness is to contrast it with greatness from a different field. If you are an icon you have to be measured against other icons.

Jerry Rice dazzled the imagination of the public with his amazing catching ability for the famed 49’ers. And just when his career seemed destined to end after he tore his anterior cruciate and medial collateral ligaments in a game in 1997 he came back better than ever before.

The second part of Jerry Rice’s career might be the most impressive. After his retirement he holds many receiving records but for the sake of this comparison let’s focus on the career records.

Career Statistic	Jerry Rice	No. 2	Difference in %
Receptions	1,549	1,289 (Tony Gonzalez)*	20%
Touchdowns	198	156 (Randy Moss)	27%
Yards gained	22,895	15,934 (Terrell Owens)**	44%

* As of 11/16/2013 Tony Gonzalez of the Kansas City Chiefs is still active ** Terrell Owens hasn’t played in the NFL for three years but still hasn’t officially retired 

Similar numbers for Sachin Tendulkar look like this.

Career Statistic	Sachin Tendulkar	No. 2	Difference in %
Test Matches	200	162 (Jacques Kallis)**	23%
Runs	15,921	13,378 (Ricky Ponting)	19%

At first glance it doesn’t look like Sachin Tendulkar stacks up that well to Jerry Rice. Where Jerry Rice is anywhere between 20 to 44 percent ahead of the next-best in his performance categories Tendulkar “only” bests his opposition with 19 to 23 percent. And since Jacques Kallis doesn’t look like he intends to retire anytime soon there is a possibility that Tendulkar’s margin might have shrunk considerably by the time Jacques Kallis retires. 

If we try and compare Tendulkar and Rice head-to-head we get more nuances in the picture.

	Sachin Tendulkar	Jerry Rice
World Championships	1	3
Salary in last year	$4 Mill	$ 873,529
Length of Career	24 Years	20 Years

I know, this is like comparing apples and oranges. Nothing can take away anything from what these two amazing athletes achieved in their careers. But like any other bar discussion its always nice to sort out the story behind the numbers.

What position should you play in the NFL?

Tell me your height and weight, and then I’ll tell you what position you’d be playing in the NFL. That seems to be the lesson we can learn from the visualization shown below. Of course it doesn’t tell us if you’re going to play offense or defense, so you’ll have to decide that by yourself. Or let your coaches do that for you.

The visualization shows the correlation by position between height and weight of current active NFL players. It was compiled by Dr. Craig M. Booth who until recently worked as a computational astrophysicist at the University of Chicago.

What is so great about this visualization is that it’s intuitive, understandable and it confirms many of the stereotypes many of us have about the different position player types. Wide receivers and cornerbacks are the lightest players on the field and linemen occupy the other end of the spectrum (tall and heavy).

The visualization made its rounds on internet message boards and forums a couple of weeks ago. Most of the comments apart from the obvious (fascination) centered around the fact that it was strange to see how clustered the weight/height relation was for each position. But if you follow the NFL long enough you’ll know that this should be expected. Every offseason there’s a story about a different player who’s considering switching position and in order to do that he needs to gain/lose weight.

This happens because NFL as a league is in many ways very conservative. In other words the many position coaches that crowd rosters of NFL and college teams have a mental map in their mind resembling the visualization Dr. Booth presents. So when a Linebacker is contemplating moving to Defensive End his position coaches will usually tell him to spend the offseason putting on 30 extra pounds (of muscle).

It could be interesting to see how the map of different position players’ height and weight has changed over time. That way you could see the effect of different events over time like how legendary Linebacker, Lawrence Taylor, changed the Left Tackle position (see Michael Lewis’ book “The Blind Side” for specifics).

While the visualization in itself didn’t surprise me as much as it fascinated me, there were a few surprising takeaways. Here is my list of the 3 biggest surprises from the visualization.
1. Defensive linemen have bigger variety of weight than offensive linemen
2. Cornerbacks are on average shorter than the wide receivers they cover
3. There is a Wide Receiver who’s only 5' 5" (1.65 m)

What Happened to Green Energy?

The Inconvenient Truth seems to be that investments in Clean Energy have fallen lately. And that trend is going to continue for quite a while. Investments in green energy fell by 14% in the third quarter of 2013 compared to the previous quarter. Only a Christmas shopping spree in clean energy can prevent 2013 from being the second year in a row with falling investments in renewables and energy-smart technologies.

The major challenge is that most Clean Energy Technologies are still in an early face of their product life cycle. Heavy investments are needed for Research & Development and the rewards for investors when the product goes to market are far from guaranteed. This is why government subsidies are necessary to mature this market.
In the US President Barack Obama has done what he could to help the green cause. This has brought good results in the form of employment and more environmentally safe technologies being installed (electricity generation from wind and solar power increased nearly 71 and 40.3 percent between 2008 and 2010) . But unfortunately the costs have been too high.
According to figures from The Institute for Energy Research $34.4 Billion have been invested and 2,298 permanent jobs have been created. An average of $14.49 million of tax payers’ money per job. With the recent budget crises in mind it’s probably safe to bet that the US will not be ramping up its Clean Energy investments any time soon.

And the same picture shows up all over Europe with Germany the most notable country to limit and/or withdraw subsidies. The government subsidies for installing solar panels used to be so generous in Germany that nobody could afford to not have solar energy. But since job creation has halted even governments have to be efficient with how they’re allocating funds.

To end on a positive note, though, if the light at the end of the tunnel is fueled by green energy it should still be burning when government subsidies are ready to return.

What Stephen Levitt didn’t understand about ”Good to Great”

A little while back Stephen D. Levitt, co-author of “Freakonomics”, wrote a blog post criticizing Jim Collins’ seminal book “Good to Great” . Unfortunately, everything he criticizes only underlines how little he understands about business and stock markets.

And I mean that in the nicest way possible.

No joke, Levitt will even be the first to admit that he doesn’t know anything about stocks, markets or general economic patterns. “If you ask me about whether the stock market's going to go up or down, if you ask me whether the economy's going to grow or shrink, if you ask me whether deflation's good or bad, if you ask me about taxes-I mean, it would be total fakery if I said I knew anything about any of those things" he says in the foreword to Freakonomics.
What then prompted him to go out of his way to criticize Collins’ book is beyond me. But it doesn’t stop me from defending a book I find to be very insightful.

Levitt has misunderstood the basic premise of the book since he thinks the book is about companies that made “the transition from good to great, but they also had the sorts of characteristics which made them “built to last” (which is the title of Collins’s earlier book).”
Although he is right about the part that Collins’ earlier book was called “Built to Last” the book’s stated theme is not as he writes. “Good to Great” is simply about companies who were good (part of the S&P 500) and became Great (beating the average market return three times over a 15-year period). It is about the strategies that these companies utilized and what sets them apart from other companies. The book describes periods of different companies and what they did during a particular 15-year period of their history. Nowhere in the book does it guarantee that these companies are going to keep giving continued above-average returns.

Levitt has noted that Good to Great companies don’t guarantee perpetual above-average returns, but his message “Overall, a portfolio of the “good to great” companies looks like it would have underperformed the S&P 500” only proves that he doesn’t know anything about investing. Timing is the essential art of investing. If Levitt read the book thinking he was going to find the magic formula for getting continuous risk-adjusted returns above the mean he’d be wrong. There’s no secret formula for finding companies that will always get you returns above the S&P 500. If there was a secret formula by the time the book came out the market would have adjusted prices to predict such future returns.
The fact that Levitt hasn’t even taken the time to research if the companies stuck to the strategies that helped them make the leap from Good to Great further accentuates that his blog should not be taken that seriously.

But the timing of the blog post is curious at least. As published on July 28th 2007 Levitt ends up looking like one of the last passengers on the Titanic saying that the course of this ship is not safe. Only a few months later the whole market crashed (including the Good to Great companies) and no one could predict who would outperform the S&P 500.
The fact that the accompanying graphs to Levitt’s blog post show the intra-day movements of 3 Good to Great-companies once again proves that the Freakonomics-team isn’t in the investment business. Only Day Traders pay any attention to intra-day price changes. And Day Traders don’t read Jim Collins.

To quote the honorable Jay-Z:
“Audemars that's losing time, hidden behind all these big rocks
(Ball so hard) I'm shocked too, I'm supposed to be locked up too”

Unfortunately, that’s not really a cool way to finish off this post. Especially because I haven’t expressed my deep respect for Levitt and most of his writing. “Freakonomics” and “Super Freakonomics” were hugely inspirational reads for me. But in those books he and Dubner wrote about subjects where they’d done the necessary research to make bold statements. The same can’t be said about his ramblings about “Good to Great” where he in a hastily-put-together blog contradicts a researcher whose team has spent the equivalent of more than ten person-years researching for the book.

To quote Jay-Z from the song “U Don’t Know”
“The coke prices up and down like it's Wall Street, holmes.
But this is worse than the Dow Jones, your brains are now blown”

I got 99 Problems but a Blog aint one

It’s been almost a year and nothing new has been added to the blog. Behind the Numbers has sunk in to the kind of slump that most blogs end up in. The “343 Days since Last Update Slump”.

It’s been so long that my last Blog Update was about The Champions League Twenty20 Cricket tournament. But not the one being played right now in India. The one from last year. In the blogosphere that type of silence is deadly.

For almost ten years I avoided blogging because I didn’t want to end up like the 99% of bloggers writing for no particular audience but themselves and while doing that for a couple of weeks then just stop and never update. So when I finally started my own blog I wanted it to have a specific focus. I decided to write the stories Behind the Numbers. My inspirations were blogs like The Big Picture, and The Economist’s Game Theory blog. That’s how I wanted my blog to be. Because I didn’t have a job at the time I had lots of time to write. In short I tried creating a job for myself by blogging.

There are lots of stories about bloggers who turned there blogs and passion in to daytime jobs. My favorite, all-time hero Bill Simmons did just this. After graduating college he worked for a newspaper for a couple of years covering high school football. Since that didn’t get him where he wanted, he quit his job, worked as a bartender and started blogging. His prose and style earned him many readers and he was “discovered” by the now defunct ESPN Page2. Today he holds a senior position within that company and is the godfather of sportsjournalism 2.0 in the US through the Grantland website.

I tried to do the same without the same conviction. I mean, I love writing, but after being one of many freelance journalists who suffered at the hands of the financial crisis I recreated myself in finance (if you can’t beat them, join them). Today I work for Wells Fargo, I’m a CFA Level II Candidate and I’m on my way to a great career in finance. But along the way of getting more efficient something was lost.

And it wasn’t until I read Lauren Foster’s CFA Blog this week that I was able to describe what I was losing. The blog Weekend Reads for Advisers: Investing, Poker, and Retirement talks about following your curiosity towards subjects that not necessarily are related to your job. In fact, she explains my challenge, better than anything I could’ve written:

Curiosity underpins success because it begets relentless questioning. Adam Bryant of the New York Times captured it well in the column “Distilling the Wisdom of C.E.O.’s.”
“Why ‘passionate curiosity’?” he asks. ”There are plenty of people who are passionate, but many of their passions are focused on just one area. There are a lot of curious people in the world, but they can also be wallflowers. But ‘passionate curiosity’ — a phrase used by Nell Minow, the co-founder of the Corporate Library — better captures the infectious sense of fascination that some people have with everything around them.”
And as Jason notes in his recent post, “Advice on How to Become a Research Analyst”  curiosity is an important trait. After all, by reading across a wide array of topics and publications, we create, what he calls, “a mosaic of knowledge.”

So, without further ado, this is the resurrection of my blog.  Behind the Numbers Ver 2.0 has less numbers, more stories, more hip-hop quotes, more stories about passion and play and of course, there'll still be lots of cricket, but most of all, a lot more hip-hop quotes. In fact, here’s one from LL Cool J.
