Quote from codedeep007:
you speak for yourself only. im not a quant, but if a quant i interviewed said he uses TA, he would not be hired. they are not hired to look at pretty charts and find averages. quants should understand the inherent flaws in TA.

Anything can be quantified should be called TA (PS,PE...) Those all can be analyzed by computer.
Some financial modeling are just bullsh*t: for example try to earn 2% better than the saving account based false assumption like this CDO ...
According W.B., modern Financial Engineering teaches people to do average 7%>5% is an example.
Sadly people are only interested in hiring someone can write complex statistical differential equations, we are so happy to see their ass got kicked.
