Hello Darshan,
Thank you for your comment and your question!
My advice is to ask a local investment firm for a copy of one of their research reports so that you have an example of a real research report in hand to use as a template.
You can also take a look at Jeffrey Hooke's book, "Security Analysis on Wall Street." In it he describes many of the elements of a good research report.
Another book is James Valentine's "Best Practices for Equity Research Analysts."
These three all provide a good framework for how to write a good report.
Yours, in service,
Jason
