Sensex Rolling Retuns - Some observations

I was doing some data analysis on Sensex data from BSE. I have taken the Sensex value for March end (or very close to it) for every year since Sensex was constituted in 1979. It put my mind to rest on the need to keep focussed on the long term and ignore short term market gyrations.

Some interesting observations:-
  1. The worst crash in Sensex came not in 2008 but in 1993 courtesy Harshad Mehta. Down 45% in 1993 vs 35% in 2009.
  2. The highest return for a year has been 252% in 1992!!! Again, courtesy Harshad bhai. The man giveth and he taketh away!!!
  3. So, between 1992 & 1993, investors actually did not lose a lot money if they had stayed invested. Sensex was down 10% over the 2 year period, not a catastrophe.
  4. Negative returns for over rolling 5 years starts to become lower and lower and by 12 years, it becomes zero. i.e, there has been no case historically, where an investor has lost money by being invested for 12 years or more.
  5. For a period of 3 years or more, the median return is relatively good - 14% or more.

    If you r invested for 10 years no chance of loss and avg returns of 17% much higher than fd.

    1. That is true Gaurav. The only caveat is that this is historical and no one really knows how the next 10-12 years will pan out. This can be a good study to understand the market background. I did look at the last 80 years data on DJIA and saw very similar patterns, although there were 4 steep falls (over 50%) in the last 100 years in DJIA.
