What is Margin?
Margin is essentially the difference between a product’s selling price and the cost of production.
A margin is a collateral that the holder of a position in securities, options, or futures contracts has to deposit to cover the credit risk of his counterparty (most often his broker). This risk can arise if the holder has done any of the following:
* borrowed cash from the counterparty to buy securities or options,
* sold securities or options short, or
* entered into a futures contract.

There is no secret formula that can help you navigate through the CFA program and pass the test, but an organized, disciplined approach will help you pass each level of the program and ultimately achieve your goal.
Don’t waste time, get going: The CFA Institute prescribes that at least 250 hours of independent study is necessary to pass each exam. Here is what they say : ” … a minimum of 15-20 hours per week for 18 weeks to studying the assigned readings. Allow a minimum of one week for each study session spread over several days, with completion scheduled for at least 30-45 days prior to the exam. This schedule will allow you to spend the final four to six weeks before the exam reviewing the assigned material and taking multiple online sample exams. Successful candidates report spending an average of about 300 hours reading and studying the curriculum, plus 4-6 weeks reviewing and taking online sample and mock exams.”

Here goes the why-do-I-do-it list:

Endorsed by leading Universities and Businesses.
Predictive Power – Because the PRM is broken into four exams, each of which must be passed to attain the designation, you cannot use strength in one area, say Math or Finance, to cover weaknesses in other area, say Risk Management
But once you get through, it certainly adds to your credentials.
