Cash is valuable
Having more is better than having less
Having more today is better than having more in future
- Why? Inflation
The stronger promise, the more valuable the cash today
1
The capacity of the asset to generate cash flows
The timing of those anticipated cash flows
The expected growth of those cash flows
The uncertainty of those cash flows
Valuation Drivers:
INVESTMENTS | BODIE, KANE, MARCUS
Valuation of asset: CF / 1+ discount rate
CF bigger, valuation bigger
2
Single cash flow
Annuity : a stream of constant cash flows over a specific period of time
Growing annuity : a stream of cash flow over a specific period of time growing at a constant rate
Perpetuity: a stream of cash flow that are the same number forever
Growing perpetuity : a stream of cash flow forever growing at a constant rate
PV
INVESTMENTS | BODIE, KANE, MARCUS
A growing annuity is the same as annuity in that payments for both end at a certain period. However, payments of growing annuity increase at a constant rate while payments of annuity are fixed. Growing annuity is also similar to growing perpetuity; payments of both increase at a constant rate.
3
Value of Asset = CF1/(1+r)^1…………CFn/(1+n)^N
r=discount rate (capture the inflation and the riskiness of this cash flow)
The cash flow is bigger, the value of asset is bigger
The discount rate is bigger, the value of asset is smaller
PV
INVESTMENTS | BODIE, KANE, MARCUS
Larger cash Flows = higher value.
The faster the receipt of cash flows = higher value.
The higher the growth of the cash flows = higher value.
The more certain the cash flows = the higher the value.

The prices of securities fully reflect available information to investor
If this were true, there would exist neither underpriced nor overpriced securities

Antecedents of the Crisis
Fed response to high-tech bubble of 2000-2002 was an aggressive reduction in interest rates
T-bill rates dropped drastically between 2001 and 2004
As a result, this recession was mild and brief, engendering a new term, the “Great Moderation”
Historic boom in housing market resulted from seemingly stable economy and dramatically reduced interest rates
Greater tolerance for risk, such as securitized mortgages

Changes in Housing Finance (1 of 2)
Old Way
Mortgage loans came from a local lender, such as a neighborhood savings bank or credit union
Typical thrift institution would have as its major asset a portfolio of these long-term home loans
Thrift’s main liability would be accounts of its depositors
New Way
Securitization is the pooling of loans for various purposes into standardized securities backed by those loans, which can then be traded like any other security
Fannie Mae and Freddie Mac became the behemoths of the mortgage market

New product resulting from securitization model
Securitization by private firms of nonconforming “subprime” loans with higher default risk
Trend towards low- and no-documentation loans
Little verification of borrower’s ability to repay

A CDS is an insurance contract against the default of one of more borrowers
Purchaser of the swap pays an annual premium for protection from credit risk
Investors bought CDSs to insure safety against subprime loans
Some swap issuers did not have enough capital to back their CDSs
E.g., AIG alone sold more than $400b of CDS contracts on subprime mortgages
