There are many sites where you can find detailed info about various companies data.
Like you can use
www.moneycontrol.com and search the quote for a particular company (though there are so many popups advt on the site). You can find every info about any company like financial results, company address, news etc there.
Alternatively, you can use our menu on the top left for the latest quotes, news, nav etc. (Powered By Sharekhan.com).
N if u r net savvy, use google search and find info about your favourite company, you will get so much info but do look for information date... it should be latest.
Like recently I searched google for "bgr energy ipo grey market price" and found plenty of websites giving me the good information about it. But we have look for the info which is latest and the best and avoid info which are from non-reliable sources which might just be rumours.
Bye...
