Valuation¶
Debt¶
It is the rate of return the firmโs lenders demand when they loan money to the firm.
Forms of Borrowing¶
Type | |
---|---|
Private | Bank Loan |
Public | Bond/Debenture |
Bond¶
Certificate of
Term | Fixed? | Meaning | Formula | Unit |
---|---|---|---|---|
Face/PAR/Book Value | โ | Listing price of the security | \(\text{PAR } = \frac{\text{Total Amount}}{\text{No of bonds}}\) | Currency |
Coupon Rate | โ | Interest rate | % of face value | |
Time to Maturity/ Time to Expiry | โ | Bounding time period by which face value will be repayed (at every payment instant, we only pay the coupon amount) | ||
Credit Rating | Partially | |||
YTM (Yield-to-Maturity) | IRR of the bond Actual return for the buyer of the bond |
Bond Traded at | Purchase | Returns |
---|---|---|
PAR | Market Value = Face Value | YTM = Coupon rate |
Premium | Market Value > Face Value | YTM < Coupon rate |
Discount | Market Value < Face Value | YTM > Coupon rate |
Bond Price¶
\[ \text{Bond Price} = \sum_{t=1}^T \frac{\text{Coupon } t}{(1+\text{YTM})^t} + \frac{\text{PAR}}{(1+\text{YTM})^T} \]
\[ \text{Bond Price } \propto \frac{1}{\text{Interest Rate}} \]
This is because, if interest rate increases, lenders will go to loan market, and everyone will sell their bonds.
Misc¶
Run-on-the-bank¶
Banks should have minimum liquidity, to ensure that
- If a private bank falls show on SLR, they can request from government, using Rapport
- If a govt bank falls show on SLR, they can request from government, using Reverse Rapport
Rapport¶
Repurchase agreement
Reverse Rapport¶
Why are Govt Bonds Risk-Free?¶
Chance of default is lowest.
Preference Shares¶
- Hybrid of debt and common shares
- Fixed dividends
- Deferrable dividends
- They donโt have voting rights
- There is no expiration date
- It is the only real example of perpetuity
- Usually higher return than bonds
\[ k_p = \frac{d_p}{p_p} \quad \left(\frac{c}{r} \text{ from Perpetuity} \right) \]
Common Shares¶
Returns
- Dividends
- Capital Gains
Difficult to estimate pricing, as there are so many variables in play
- Unsure cashflows
- Life of investment is infinite
- No way to calculate required rate of return
It is frowned upon for a corporation to reduce dividends. Hence, if it increases dividends, it does so very carefully.
Book value Method¶
Most appropriate for established companies
Dividend Growth Model¶
\[ \begin{aligned} g &= \text{ROE} \times \text{Retention Rate} \\ D_t &= D_{t-k} \times (1+g)^k \\ \implies P_t &= \frac{D_{t+1}}{k_\text{CS} - g} \quad \cancel{+ \frac{P_\infty}{(1+r)^\infty}} \end{aligned} \]
where
- \(g =\) dividend growth rate
- non-zero constant percentage change of dividend from one year to next. If non-constant, we take average \(g\) over a few years
- \(g = \text{ROE} \times b\)
- \(\text{ROE \%}=\) Return on Equity
- \(b \% =\) Retention rate, Plowback rate
- \(b \% = 1-\text{Payout Rate}\)
- \(k=\) market discount rate
Dividend Growth | \(g\) | |
---|---|---|
No | \(0\) | Perpetuity |
Constant | \(\ge 0\) |
Limitations¶
- Assumes constant growth
- Only works when \(g \ne 0\)
CAPM¶
Capital Asset Pricing Model
Describes relation between systematic risk and expected rate of return of risky investments.
Expected return on a risk investment depends on
- Risk-free rate (return rate of bond)
- Risk premium, depending on \(\beta\), where \(\beta\) is the sensitivity of the stock wrt the market
\[ \begin{aligned} k &= r_\text{min} \\ &= r_f + \beta \Big( E(r_m) - r_f \Big) \end{aligned} \]
where
- \(r_\text{min} =\) Required return of investment
- \(r_f =\) Risk-Free rate
- \(r_m =\) Stock market return
- Take only recent data (say, 1 year or so)
