Brush up- Expected concepts / formulae /common errors / general tips / one liners

Have tried to be accurate to the best of my knowledge. Your feedback/suggestions would be appreciated. All the best

A.** General Tips/Silly mistakes/Common errors**

  1. Although the exam is for 4 hrs spanning 100 questions , time will be a constraint as numerical questions are calculation intensive

  2. Be very familiar with the use of the calculator esp when to comes to calculating e,LN, combination , power , PV etc

  3. Set the decimal to 9

  4. Focus on Products and VaR as they weigh 60%

  5. Skip question immediately if u are stuck [We wouldn’t like our paper to finish at Q no. 84 when there could be possible sitters in the last bunch of 16]

  6. Many questions have multiple lines. Read the last line to directly get to the question and then read the para [understanding would be better]

  7. See the answer options before solving [in many of them if you can guess the direction viz sell/buy – long/short-gain/loss- bond price movement –up/down -2 options can be eliminated]

  8. Expect 20% of the questions to be really tough. The key is to identify them and leave them in the first .

  9. Expect that u may not remember all the formulae [everyone goes thru it is natural]

  10. Keep a tab of time . You should have solved around 25-30 questions/hr .

  11. Shade the correct option. [sometimes in a stressed situation we subconsciously shade the wrong one]

  12. Inputting of data in the correct form is critical [continuos compounding if the risk free rate is 5% , use .05 not 5 . In duration for 5 basis points use .0005 etc]

  13. Read the question carefully- they may have double negative or may ask which of these is FALSE/INCORRECT ?

  14. Pay special attention to calculation of variance/SD/volatility. Often it requires squaring or square rooting.

  15. Do not expect to master all concepts.

  16. Revisit/Reconfirm the conceptual subjective questions. They can be really tricky.

  17. Although people feel that 70% is required for passing , my belief is that 60-65% should be good enough [pass rate is 50% and expecting 50% of them to score more than 70% does’nt appear to be probable]

B.** Handy Material**

  1. 6 pager schweser’s quick sheet – at the end of practice exam book of schweser

  2. Formulae at the end of Schwser notes

  1. VaR – [note that VaR is different if they are talking of confidence level or significance level]

  2. Portfolio volatility [remember to square root]

  3. CAPM- the mother of all equations

  6. Change a portfoloio beta= [Target beta – existing beta] x Portfolio Value/Value of underlying

  7. Continuos compounding rate

  8. Theoritical price of bond- discount cash flows

  9. R fwd= R2T2 – R1T1/T2-T1

  10. FRA- remember to discount the net cash flow

  11. Estimated change = - Duration effect + Convexity effect [Note the opposite sign]

  12. Term theories- Expectations/Mkt segmentation/Liquidity preference

  13. Fwd price = Spot x e ^rT . In case of dividends replace rT by r – q)T

  14. Interest Rate Parity= F=S x e ^ ( rd- rf) T

  15. Backwardation/Contago - diff from normal backwardation/normal contago- In the later the comparison is between expected spot and fwd price

  16. Dirty price= Clean price + Accrued Income

  17. CTD Bond= which minimizes Quoted Bond Price - (Settlement Price x Conversion Factor )
