Thanks saint for your in-depth reply
What you said is very right but to follow this, requires lot of understanding of markets, of technicals and good software and lots of data etc.
I bought ACC at around 700 as I felt it's available at good price even though I noticed it's falling and falling with each passing day... may do some averaging at around every 10% fall from my buying price till it reaches zero or reverses its trend. Tough time for cement sector at least till the inflation comes down. The bad thing is these stocks sometimes reverse their trend so quickly, sometimes in few hours or days, that only professional traders using advanced softwares notices it and aam-aadmi is left at a loss.
Just wondering if all the people will start waiting for downtrend to end and no one will come to buy, then perhaps it will continue its downtrend forever or will there be a time when a buffet-like will see that it has taken enough beating, learnt his lessons and now lets buy it... shall wait and wait and see and see.
Anyway, I will learn more about trend change detection etc as I am new to all this.. not much worried about ACC but do not know whether I should be bullish on cement sector right now with around 1 year perspective as many cements stocks are at their 52 w lows where they did not reach even after great falls of jan, feb and march.
Thanks.
