I'm getting admission in ms finance
I want to get help abot selecting the research topic in ms finance

One approach would be to run down the Table of Contents and skim the chapters of any good corporate finance text. Brealey & Myers is one of the "go to" classics (and a personal favorite of mine); Ross & Westerfield is another good one. In either case--or from any other similar text--you'll have the majority of the important topics and subsets of finance laid out for your perusal.

For a more advanced "re-visiting" of the important topics, try Copeland & Weston's Financial Theory and Corporate Policy.

To supplement that approach, consider spending some time with several days of The Wall Street Journal and / or The Financial Times. That'll highlight for you the more contemporary finance topics which are generating the higher levels of popular buzz these days.

Just a couple of thoughts... you'll hear and think up plenty more. Best of luck in your studies; you've picked an exciting field!
