Hello,
Please look at the monthly chart of Infosys (for ex.) and bring your attention to the volume.
One will notice that there is a distinct bifurcation in nature of volumes around 2004. After 2004 the volume suddenly thinned out.
Mathematically,
Let,
A = total volume of shares traded from 1998 to 2004 (adjusted for spilts not bonuses, since they do not show in the chart data)
B = total volume of shares traded from 2004 to current, 2012
Our focus is A/B;
For infosys,
A = 5003679962
B = 998802680
The ratio A/B = 5
If A is almost 5 times greater than B, then one would think that participation was relatively weak after 2004. After 2004, even the major monthly supports do not have serious participation. Therefore, any semi-serious cue (global or local) could easily break these supports. This is because,
Ones who bought before 2004, at sub-700 prices, would be happy to book profit at current prices. No wonder Infy saw the sharpest fall in its recent history.
Please provide your views, especially contrary ones.
