Q

Explain the end to end situation, 1 I got 100m in equity, 20m in Cash. I want to reduce my tracking error - what do i do

A

Bang. First. You’re going to want to buy x future contracts on the index. Lets say each is worth 1,000$ with a 10x multiplier
20m/(1000*10) = 2000 contracts.

Then she invests the 20m in a TD at whatever, 3%?

Then after a year, the index is up, the future price has increased from 1000 to 1050. 50 points * 2000 contracts * 10 multiplier = 1m

I get the return from my TD of 600,000.

So i have made an extra 1,600,000$ plus my cash back and the return on my equity.

Bull Spread - explain

A

It is when you BUY a call option at a low strike, then SELL a call at a higher strike price.

36
Q

Cash flow risk and market value risk. How is a floating note effected by these risks (IF AT ALL)

A

It is subject to cash flow risk because you dont know what your cash flows will be in n months.

Since the duration is so low for a floating rate swap, there is no real market value risk

37
Q

Formula for notional principle (how much you have to invest) to reduce/increase duration exposure using a swap

A

it is:

Value Swap* (((Target D - Actual D)/ Swap D)

D = Duration

38

Q

Explain the process of an FRA

A

So, you go to the bank, and lock in an interest rate for some point in the future for an amount you intend to borrow. This is because you think interest rates will go up and you dont wanna pay more than you have to

The day comes, and interest rates have increased. The bank pays you the discounted value of the loan amount multiplied by the difference in interest rates, then you carry out the loan on normal terms.

54
Q

How to work out if a swap is better than just borrowing - what is the process of interest rates and swap interest rates?

I am asking, if you were to work out if its better to just borrow vs using a swap, how would you work it out using swap rates and interest rates

A

So, is the interest rate from a bank better than the NET amount of what you would pay if you went through the swap process.

E.g loan at 5.5% (which is -5.5%)
OR
loan in Colombia at 6% (-6%), plus the amount you recieve on the swap (5%) minus the amount you have on the swap (4%)
-6+5-4 = -5%.

The swap is better

Ignore which currency is which

This assumes interest rate parity and well integrated markets

55
Q

Explain what a currency basis swap is

A

It is when there is a DISCOUNT on the swap rate of one of the currencies in a currency swap because the counterparty currency is in high demand (like the USD)

You subtract the negative basis points from the swap rate to determine the effective interest rate/cost of debt.

You convert everything into one currency and compare if the swap is cheaper than just borrowing direct from the currency you want

Q

If i buy a call option, what does that do to my delta?

A

Increases

60
Q

This one is important Guy.

How do you hedge tail risk using volatility VIX options? Why does this make sense?

A

What happens as vol increases? Prices decrease. So if you go LONG volatility, you are in fact reducing your tail risk. You can offset this position by also selling put options.

If vol gets gnarly, that is a tail event. Buying the call options on this volatility for a discount is an awesome idea.

61
Q

If i sell a call option, what position do i have on theta

A

positive

62
Q

Explain the process of a calendar spread (calls)

A

Sell short dated calls and BUY long dated calls

This is when you assume no vol in the short term, but perhaps some hectic upside after earnings or something in the future

63
Q

Explain a volatility skew

A

It is when there is HUGE volatility on Out the money calls/puts, and lower vol for those options that are at or in the money.

This means that there are many hedgers/people buying insurance around

64
Q

If there is an uptick in volatility in OTM puts - what sentiment is this sending?

A

This is inferring an upcoming bearish market - people think that prices will go down, so they are buying insurance

65
Q

What if there is an uptick in OTM calls - what sentiment is this sending

A

Bullish market to come

66
Q

Assume that there is an uptick in OTM put volatility, but you think it is overcooked - how might you take advantage of that?

A

Buy calls and sell puts. The puts are going to be selling at a premium because everyone is buying them, so sell some if you believe this reality will not be realised.
