Tech Musings - Review

Shanghai composite has sold off below 2000 and the stop loss of my last call had been triggered. Shanghai composite has been selling off gradually since March 2011. If you observe the chart you can see that it had hardly given any retracement since the fall started in March 2011. In last 7 years I have seen many stocks (where underlying fundamentals are extremely weak) selling off but I have never seen an index selling off like this. It seems that Shanghai composite won’t find any support before it reaches 2008 -2009 lows of 1700 level.

Next chart I am presenting is of Nifty. Nifty has moved up sharply after a brief correction which I indicated in my post on 17th October 2012.  As readers can see from the given chart Nifty did 23.6% retracement which is 5560 levels while I was expecting a deeper 38.6% correction at 5416. As I mentioned in that post any sell off would be a good buying opportunity, Nifty bounced back from there and had made a new high.

In the third chart we can see that nifty has complete 76.4% retracement of the entire fall from 6350 to  4500 levels.  I wrote the following in my post on 29th September 2012I have updated my view on nifty in the beginning of this month when Nifty was trading at 5342levels.  Nifty closed this month at around 5703 i.e. up move of around 7%. Going forward from there are quite a few possibilities. Going only by chart analysis it seems that Nifty should move towards 6350 levels. Although there will be lot of congestion around 5800 -5900 levels.”


Nifty is has touched the fag end of the congestion level but breaking above 5900 may be difficult for the index. I think the probability of Index going up to 6350 is more than 60% but Nifty may see some pull back at these levels. Since market has moved up sharply it would be advisable for traders to book some profits and wait for appropriate entry points.

Inefficient market hypothesis

Being a follower of technical analysis I am an adherent believer that markets are efficient only over a period of time, but they are always inefficient at any given point in time. I have always felt that assumptions used by theorist to prove their efficient market hypothesis only occur in Alice’s wonderland. One of the prime assumptions of efficient market hypothesis is that information is uniformly available to every investor and is instantly priced in. I found a recent write up by Ashwath Damodaran which I am sharing with my reader.

You will notice that in fourth chart that target company stock price starts to increase 2 weeks before announcement is made public. If the markets were efficient the stock price of target company should move up instantly on announcement of acquisition but that is not the case. So why would the stock price of target company increase before announcement is made public?

This happens because information of the impending announcement is already leaking into the market and someone is acting on that information and is gradually accumulating shares of the target company.  Source of such leakage could be friends and relatives of auditors, employees, lawyers, consultants etc.

One of the basic assumptions of technical analysis is price discounts everything, which means that all published and unpublished information is reflected in the price through actions of market participants. That is why technical analysis is able to predict price movements even when there is no apparent news in the market.
