Which discounting rate should I use?

Posted at: 2014-12-05 
Term Deposit - Having 100% safety but income is low. Less risk with less rte of interest. Good for those

who do not want to take risk,especially for aged people. Liquidity is more Can be closed be

before maturity in case of need,with a minor penalty

Treasury Bonds Risk is less and income is slightly better than Bank deposit. Usually for long term

In case of necessity for money cannot be cashed immediately.

Common Stock High Risk and high income. Good for long term. Chances are there to incur loss

I have a study project where I need to analyse different investment opportunities such as term deposit, treasury bond and common stock. Each must be brought at one point in time using common discount rate. Which discount rate in real world should I use? Fed Discount rate or some other?
