know go off the rails. Anyway just know these five bad boys. Here we go.
- 00:30
Principal one, the time value of money. Mantra, a dollar today is worth more than
- 00:36
a dollar tomorrow. Why? Well because you can in theory, always invest that dollar
- 00:41
and get a positive financial return from that investment. If you picked quote, the
- 00:45
safest bet in the world, unquote. Well by investing in American Treasury bills,
- 00:50
which are guaranteed more, or less by the American government's ability to tax its
- 00:54
hardworking people. Well then you'd get a small return on your [man talking in dark room]
- 00:59
investment. For a more practical example think about you investing a thousand
- 01:03
bucks to buy a t-bill yielding three percent.
- 01:05
Well bonds like this usually pay twice a year, so six months later you'd get what?
- 01:09
Well if your total interest per year was three percent, on a grand invested then
- 01:13
you'd get thirty bucks, a year, for doing a whole lot of nothing. Other than let[money in bank vault with American flag]
- 01:17
your grand sit with the Gov. So twice a year you'd get a check for fifteen bucks.
- 01:21
But it's about two lattes, but it's a positive investment return that's pretty
- 01:25
much guaranteed. Silly example, but there were about a hundred eighty two point
- 01:29
five days, that made up the six months, that yielded to you, your $15. So how much
- 01:35
did you earn per day, based on that figure? Well about fifteen dollars,
- 01:38
divided by one hundred eighty point five, or about eight cents a day. Well the gist
- 01:42
here is that, the thousand dollars today, was worth more than the thousand dollars [January calendar]
- 01:47
tomorrow. That is invested in the form of a very safe 3% T bill. The dollar today was
- 01:53
worth about eight cents more than the dollar tomorrow.
- 01:56
Well time values a pretty dull concept when it's three percent a year, on a
- 02:00
relatively small amount of money. But let's calculate something more fun. Okay,
- 02:04
our idea of fun, sorry. We netted a hundred million dollars after tax, after
- 02:08
an IPO of a company we founded. We want some toys and bling. First off we want
- 02:13
to shrink the world, so let's buy a jet. A
- 02:15
shiny new cj3, cost about twelve million dollars and another fortune to operate,
- 02:21
to ensure, to store, to gas up, to pilot and so on, but don't let's ignore all that. So
- 02:27
we plan to keep it 20 years. After 20 years, the plane will be worth, [jet flying]
- 02:30
not much. Figure four million dollars, at auction, so we'll lose eight million
- 02:34
dollars over twenty years, or four hundred grand a year, so yeah that jet
- 02:38
was expensive. But it gets way, way, worse. With a 20 year time frame, we could have
- 02:43
felt pretty good about putting our money in the stock market in equities, in the
- 02:47
form of an index fund. Over the hundred and fifty or so years that the modern
- 02:51
stock market has been tracked over most 20-year periods the markets gone up,
- 02:56
about eight, or nine percent. And with dividends reinvested, maybe a little [stock graph incline]
- 03:00
bit more. And yes there were bad periods where performance was flattish, but there
- 03:03
were also really good periods, where performance was way better than that
- 03:07
eight or nine percent figure. So let's just pick the middle of the curve for
- 03:10
now. If all we did with our twelve million dollars, was put it in the market
- 03:13
and get it back 20 years later in a bad stock market era. Well we'd have done
- 03:18
way better financially, than if we had bought that new jet outright. Right? We
- 03:22
lost eight million dollars for the pleasure, plus maintenance, gas and risk
- 03:26
and the comparable cost to fly commercial would have been massively [man in commercial airline]
- 03:29
less, that we won't even bother with that now. Let's bet that the market does what
- 03:34
it usually does on average over this 20 year period. It goes up 8.2% a year, well
- 03:39
had we invested in our index fund, which charged us point two percent a year for
- 03:43
maintaining that index. We would have had a ton more dough.
- 03:47
How much more? Well the magic formula, take the dollar amount you invested and
- 03:50
multiply it by one, plus the rate of return and take that quantity to the power of years.
- 03:55
Looks like this, in this case the formula would be, twelve million dollars, times [man presenting in dark room]
- 03:59
one, plus point zero eight, to the 20th power and note that the market went up
- 04:05
8.2% a year, but we only kept eight point zero percent of it because we had point
- 04:10
two percent a year in fees. This is a big deal when you look at mutual funds which
- 04:14
carry are R rated fees and then hedge funds which carry triple X's, but we'll
- 04:19
get into that later. Anyway, 1.08 to the twentieth powers about five, so gulp if
- 04:23
you would put your twelve million dollars into an index [man presenting in conference room]
- 04:26
fund twenty years later, it would be worth sixty million dollars. Instead of the
- 04:31
four million dollars, you got. And yes that's the right math we checked it twice.
- 04:35
Jets are nearly the worst investment you can make and life's short and the super wealthy,
- 04:39
well they want, what they want. As Marie Antoinette said, let them eat jet fuel.
- 04:44
Well one other note, worth noting here, is a cute little formula called the rule of
- 04:48
72. Read it, know it, know how to use it, it saves lives.
- 04:51
Well it doesn't really save lives, but it'll make yours a lot better,
- 04:54
our lawyers made us say this. All right moving on, principle two, risk and reward
- 04:58
are related. Popcorn question, why do you get eight percent returns from the stock [movie theater]
- 05:03
market in equities and you only get three percent from safe bonds. Well a
- 05:07
bunch of things affect rates, of investment returns. But the biggest issue
- 05:11
revolves, around whether you'll get your money back, or not. And/or a positive
- 05:15
multiple of your money back over time. Okay here's a chart of bond performance,
- 05:21
it's flat. Basically it's a dead man's pulse. Very few bonds don't pay back what [money on table]
- 05:26
they promised and yes a few go bust but compared with equities, bonds are a
- 05:30
massively safer investment. But you pay a big price for that safety over time. That
- 05:35
twelve million dollar jet money, invested in a bond over 20 years at 3%, well
- 05:40
ignoring taxes, which are also generally worse for bonds, than stocks. Well it gives
- 05:44
you just about twenty one point six million. Way better than owning that jet
- 05:48
and think about how many first-class commercial tickets that dough would have
- 05:51
bought. He had a lot of pretzels. Anyway with stocks, you turned your dough into
- 05:55
sixty million dollars in twenty years, so for that bond safety you just paid [finance chart]
- 05:59
almost forty million dollars, in net difference over those twenty years for
- 06:04
that safety. How's that feel? You feel safe for now, or just less wealthy? Well
- 06:09
things could have gone the other way, had you bought at the worst time. Say
- 06:13
late 1973, held them to the worst period in 1993, with dividends reinvested. Well
- 06:19
you would have compounded at only about six percent, about ten percent with
- 06:23
dividends reinvested, albeit well with a lot of headache.
- 06:26
Look at how stocks declined from 73, to 83, brutal. But also look how dividend [stock graph chart]
- 06:32
rates went up. That is when companies stocks declined,
- 06:36
they don't usually just cut their dividends, they keep paying them. And
- 06:39
investors who need and/or want the cash returned to them from their initial
- 06:42
investments are happy to get checks four times a year, because while equity
- 06:46
dividends are paid quarterly, unlike bonds, which are paid twice a year. But
- 06:50
look at the chart, could you have stomached being down almost 50 percent
- 06:54
from 73 to 79? Would you have panicked at just the [bond action site]
- 06:58
wrong time and sold all of your stocks and moved into bonds at just the wrong
- 07:02
time? Well taking on risk is a lot about personality and liquidity, ie
- 07:06
you don't need that investment to be cashed out tomorrow and well it's about
- 07:11
courage too. But over time as you take bigger risk you would expect to be
- 07:14
rewarded incrementally, for taking on that risk. And there are times to not
- 07:18
take a lot of risk, of course as well. Like if you're planning on buying a home [pink house]
- 07:22
in six months, well you likely don't want to be invested in the market. In a bad
- 07:26
six month period, things can go down a lot. The big fat hairy idea here, well
- 07:31
it's that time bails you out of risk when you're investing in stocks. If you
- 07:35
can hold an investment a very long time, historically it's made no sense to own
- 07:40
bonds instead of stocks. All right moving on principle three, the market as a
- 07:44
popularity contest, versus being a weighing machine. Warren Buffett, the [man walking out of pool]
- 07:48
Michael Phelps of public investing said, in the short term the market is a
- 07:52
popularity contest. In the long term it's a weighing machine. Well what on earth
- 07:57
does that mean? Well he's referring to short-term and long-term thinking in
- 08:01
investing and Buffett is a famously long-term greedy investor. That is
- 08:05
Buffett likes to buy things and stick them in a drawer for decades, not weeks.
- 08:09
Over time market prices are truth, they are accurate, they are honest. But in
- 08:15
short periods of time the market can go crazy. Later in this course we'll get
- 08:19
into the internet bubble of the late 1990s, where companies would go public on
- 08:22
very little revenue, with valuations of billions of dollars, many of them died, or [graveyard with tombstones]
- 08:27
simply had aweful investing returns, due to the schmuck, or speculative buyers who
- 08:31
bought them. A few did really well, a little company called Google's one of
- 08:35
them, Amazon's another, eBay, PayPal another. But most ended up doing poorly if
- 08:40
you held them 20 years. Conversely toward the end of the
- 08:42
2008 nine mortgage crisis, a ton of companies were trading the other way, Ie
- 08:47
crazy cheap. And these were stable always gonna be there companies, like
- 08:52
coca-cola and Pepsi. Which traded down to below, ten times earnings at one point. [soda market graph chart]
- 08:56
Like the market in the short term, was telling you that the odds of people
- 09:00
drinking drinks, not just soft drinks was kind of an iffy proposition.
- 09:04
Well things normalized, with Coke and Pepsi trading at right around there
- 09:07
adjusted historical price, to earnings ratios in the low 20s, eventually. Key
- 09:12
takeaway, be sensitive to the sentiment the market is feeding you, but when you
- 09:16
buy stocks for the long haul just buy good companies and good industries, right.
- 09:20
Even if you overpay in the short run, good companies bail you out in the long
- 09:25
run. All right, principle four, cash is king. Ever hear of Hollywood accounting, [Hollywood sign]
- 09:30
profits, well they don't exist when the talent in the movie participates, or gets
- 09:35
a percentage of them. Let's go through a simple example with something a bit more
- 09:38
tangible. The company, We're Nuts about lug Nuts, has four hundred million
- 09:42
dollars in revenues, in a given year, and 300 million dollars in expenses. Leaving
- 09:45
a hundred million dollars, to be taxed. Tack on a 30 percent tax rate and after
- 09:49
30 million dollars in taxes, the company is left with seventy million bucks in
- 09:53
earnings. Well the shady mystical figure, in all of [man silhouette]
- 09:56
these calculations is the notional definition of expenses. Let's say the
- 10:00
company spent three hundred million dollars on a factory, to stamp out its
- 10:03
lug nuts more efficiently. Well the accounting rules might require that all
- 10:07
that money be expensed, in three years or it might be in 30, or it might be viewed
- 10:12
as an investment and it just stays static forever, held that Book value. If a
- 10:17
company had to expense everything in three years, well then the company would
- 10:20
be required to expense a third of that hundred million dollars of that 300
- 10:25
million each year. If they had to expense the capital expenditure of the lugnut [robot working in factory]
- 10:29
roboto stamper in three years then a hundred million dollars of profits in
- 10:33
that year in the two subsequent years would be fully wiped out. The company
- 10:37
would essentially pay no taxes and well end of story.
- 10:41
Alternately the company might have had to amortize that cost over 30 years,
- 10:46
taking off 10 million dollars a year, in expenses. From an accounting perspective
- 10:49
then the company would show 90 million of profits and pay 27 million bucks in [white board with expenses and profits]
- 10:54
taxes. For now don't worry about the numbers too much the key idea, is that in
- 10:57
order to fairly evaluate the value of a company, you have to follow the cash, or
- 11:02
cash earnings and look through accounting tricks, which can change the
- 11:06
bottom line in earnings, dramatically. All right well the magic word in all of this
- 11:10
is GAAP. that's GAAP and you're supposed to say it like that. It stands for
- 11:14
generally accepted accounting principles, and it basically just tolds that when you
- 11:18
practice accounting, you always present your numbers in the most reasonably
- 11:22
conservative manner possible. In doing so, you take away the risk of you know
- 11:27
puffing out your feathers, saying that your company is in fact more profitable
- 11:32
than it really is. For example think about the case where
- 11:34
your lugnut Roboto stamper really does wear out in ten years and it has to be [robot breaking down]
- 11:38
replaced. Well in that case the 300 million dollars spent to build it should
- 11:43
in fact be taken away in some form, amortize, depreciated in a sinking fund,
- 11:47
whatever, so that it surprises nobody when in 10 years, you owe another 300
- 11:52
million dollars to go buy, or build a new one. All right moving on, principle five,
- 11:56
last one, here stick with us. Agency problems, all right well what is an agent? [man in office room]
- 12:01
For most people when they hear that term they think about a guy in a slick suit
- 12:04
in the Hollywood office selling clients time into a studio system with a lot of
- 12:08
let's do lunch you know that regular catchphrase and that really is what
- 12:11
financial agency is about. When a client hires an agent, a relationship structure
- 12:16
is formed. That is there are legal requirements around the behavior of that
- 12:21
agent, specifically the agent has to look out for the best interests of his client
- 12:26
and he has to put his own best interests on the backburner. This structure is a [bacon cooking on stove]
- 12:29
really big deal in the financial world, because so many poor unsuspecting,
- 12:33
uneducated, people have been screwed over in the process by big city slickers
- 12:38
taking their dough, with no comeuppance. Myriad laws, regarding disclosure and
- 12:43
appropriateness of advice and other elements all have blood on their hands.
- 12:48
That is each law, that you'll learn about exists because somebody, was screwed over,
- 12:52
or sued and a new law was edited to cover that corner case situation. Where a
- 12:57
fast-talking thief, took the money of our beloved mom and pa
- 13:01
kettle. [man in conference room presenting]
