I did analysis on top 'bluechip' IT companies like on HCL tech, TCS, Infosys.
as per my valuation model (which don't work accurately on banks and IT). i get to conclusion that all these companies NOW are fairly valued. so anyone invest into these companies now, will get maximum 10-15% gain by the end of year. anything above that will be expensive for that stock which in future should correct. so I m Neutral on IT stocks now.
regarding secret cable, there are mutual fund and hedge funds which have billions of rupee invested in tcs, if they want to lower their stake in TCS stock can correct more than 2% within minutes.
