I don't usually listen to the radio much -- I get most of my news from
the web and I live 1.5 miles from work so I don't have much time to
listen in the car most days anyway.

Do you know what exactly he was talking about? Did he mention the Fannie
Mae or Freddie Mac stocks? Or was he referring to the mutual funds that
invest in so called "GNMA's" and other mortgage-backed securities?

If they were talking about GNMA mutual funds, then you need to remember
that holding bond funds is quite different than holding actual bonds. If
you hold a bond (and you plan to hold it to maturity, never selling
it) with a 5.5% coupon, then you will earn 5.5% per year on your
investment. But if you hold a bond mutual fund, it is more complicated
because of fluctuating interest rates and the fact that the mutual fund
is continuously buying (and sometimes selling) bonds. So the NAV (net
asset value) of the bond fund depends on the value of the bonds it
holds, which in turn depends on the coupon rate of the bonds *AND* on
the present (and future) interest rates that are available on the open
market.

For example, if you just bought a $100 bond with a maturity of 30
years and a 5.5% per year coupon, it is naturally worth $100 at the
instant you bought it. But if soon after you buy the 5.5% bond, interest
rates go down to 4.5%, then your bond is now worth about $116. That
is because on the bond market, the newly issued bonds are only paying
4.5%, so your bond at 5.5% is more attractive to potential buyers. If
you sold your bond after one year when interest rates fell from 5.5% to
4.5%, then you made $16 on a $100 investment for a return of 16% on a
5.5% coupon bond (this is slightly simplified but it is approximately
correct). Conversely, if interest rates rise from 5.5% to 6.5% after you
buy your bond, then your 5.5% bond is only worth about $87 on the bond
market.

Since interest rates have been falling since sometime in 2000, bond
funds have had returns much higher than the yields of the bonds they
hold over the past 2 years (because the bond fund returns include both
the interest the bonds earns and the appreciation in the market value of
the bonds they hold).

However, everything I read suggests that 30yr mortgage bonds *CANNOT* go
any lower, eg., guru Bill Gross from PIMCO: "There will never be much
less than a 5% 30-year GNMA, Freddie Mac, or FNMA mortgage issued in
size no matter what Greenspan does - and that's a forecast you can take
to the bank, with a high probability outcome. No investor in their right
mind would be on the buy side of a 30-year mortgage with a 4% coupon and
a potential extension from a 5-year, to a 12, to an 18-year average life
life staring them in the face." http://makeashorterlink.com/?M146232F2
So, if rates can't go down, they will either stay the same or go
up. That means that in the future you should expect to earn no more than
the current yield on your GNMA fund, and possibly lower if interest
rates rise.

On the other hand, if the radio show you heard was talking about
the equities, like Fannie Mae (NYSE:FNM), then the price of those
equities are driven by expections of future earnings, which in turn are
influenced by leverage, volume, and costs. So, if people expect that FNM
will increase their earnings per share (EPS) in the future (not a bad
expectation, since the population is growing), then each share of stock
should appreciate at least as fast as the earnings per share increases.

Also, Fannie Mae is highly leveraged, over the last 5 years its
debt-to-equity ratio has increased from 27 to 42. If you have a D/E =
42, you could take a $100 investment, borrow $4200 at say 4.5%, loan the
$4200 at 5.5% interest rate, then you make a profit of $42 per year on
your investment of $100, for a return-on-equity (ROE) of 42%. Not bad,
huh?

But leverage this high is unusual, almost nobody but FNM and FRE are
leveraged this high. Few banks are leveraged that high -- Citibank, for
example, is leveraged at less than 4. The problem with high leverage is
that if your income suddenly decreases for some reason, then your total
debt can easily exceed your equity (total net worth) and so you can't
meet the interest payments owed on the debt, and you can't liquidate
your assets to pay off the debt. For example, if you put your total net
worth down as a down payment on a house, and that down payment is 5%
of the house purchase price, then your leverage is 20. If your house
price appreciates at 6.5% per year and your loan is at 5.5%, then you
are earning 20% on your investment of your house down payment (you are
increasing your net worth at 20% per year, but the leverage goes down as
your home equity increases). On the other hand, if they bulldoze your
next door neighbor's lot and install a sewage treatment plant and your
home suddenly goes down in value by 50%, you lost a whopping 1000% on
your investment and now have equity of -45% of the home purchase price.
In other words, if you sold your house, then you would be short by 45%
of the original purchase price of paying off your mortgage, which means
you owe 9 times your former net worth and have no assets to secure the
debt. If you want to sell your house or if you lose your job and can't
make the mortgage payments, you will have to default on the loan.

So, if FNM's income suddenly decreases (which could happen if there
are a lot of mortgage defaults combined with fewer new mortgages being
bought) and their costs increase (if the market thinks FNM is in risk
of going bankrupt then the interest rates at which FNM can borrow money
would go up drastically and so increase FNM's costs), then there could
be big trouble. The reason they can get away with this high leverage
where banks can't, as far as I can tell, is two-fold. One, they invest
some of their reserves in derivatives which they claim hedges away
some of their interest rate risks. I have my doubts about this, since
I'm not sure *anyone* has good quantitative knowledge of all the risks
involved (it is the so called "black swan problem", see the excellent
book _Fooled by Randomness: The Hidden Role of Chance in the Markets and
in Life_ by Nassim Nicholas Taleb for more details).

But the main reason they can get away with the high leverage is because,
although their stock is traded publically and owned by individuals, they
are a "government sponsored enterprise" (GSE) and there is an implicit
guarantee that the US Treasury would step in to pay off the debts if GNM
ever blew up financially. Implicit, not explicit, so it is sort of an
assumption that everyone is making, but since the US government bailed
out the savings and loans in the 80's, and since easy availability of
mortgages (which FNM facilitates) are so important to the economy and to
voters, it is probably a good bet. This means that FNM's costs are low
because their costs are almost entirely interest payments on the money
they borrow, and the interest rates they have to pay are lower since
lenders perceive their risk of default as being lower because of the
implicit government backing of the loan.

Yes, I had heard that also. The mortgage insurance company I am looking
at is at some risk of future earnings decreasing if Fannie Mae reduces
mortgage insurance requirements, which Fannie Mae was threatening to
do. Evidently it has been worked out now, though. I have to look into it
some more, since I'm not sure why/how it worked out (maybe Fannie Mae
decided to keep mortgage insurance requirements the same when they saw
how much defaults have increased recently, the default rate has gone up
every quarter for the last 2 years)
