Shankar Sharma: You are wrong!

September 1, 2008

“Sensible soundbytes” is an oxymoron. This is what a great author has said. So if most of you know what is a black swan, you know who I am talking about.

I normally do not watch much TV – except for Ramayan or Animal Planet with my daughter. However, I am many times under great pressure to watch the business channels – from friends in the media.

Yesterday, I believe, Mr. Shankar Sharma came on NDTV Profit and said “The index will not reach 100,000 – not in my life-time – and may not be in your life time too, and you are much younger than me.” Frankly, Mr. Sharma you look young, and maybe you are about 45 years of age. However, for our purposes may I please assume you are 50? May I also assume that you will live to the age of 72 years? i.e. we are talking about 22 years. May I also assume that India will grow and there will be inflation in India? i.e. we are talking of 6% growth + 6% inflation. That is we will get a growth of at least 12% p.a? I know about standard deviation, and I also know that we will not grow at this constant rate….however 12% over the next 22 years will happen.

On this assumption Mr. Shankar Sharma the index will grow as follows:

50 16,307
51 18,753
52 21,566
53 24,801
54 28,521
55 32,800
56 37,720
57 43,377
58 49,884
59 57,367
60 65,972
61 75,867
62 87,248
63 100,335
64 115,385
65 132,693
66 152,597
67 175,486
68 201,809
69 232,080
70 266,892
71 306,926
72 352,965

Best performing fund – compare risk and return!

January 18, 2008

It is easy for the common investor to get carried away by the agent telling him about the “best performing fund”. The question to ask is “How will the fund manager maintain the same rate or a similar track”. The answer is we cannot. Check out the article on risk and performance. See the amount of risk the fund manager is taking on the portfolio. Afterall whether you are an institutional investor or a lay investor, the most important question to ask is “What is my return..and how many sleepless nights did I spend to get this return”. In technical parlance this is called “risk adjusted return”. RaR is more important than just R.
