Financial Engineering

  

Categories: Banking, Investing

Every year, around tax time, you probably start thinking, "can this stuff get any more complicated?" Well, financial engineering is here to say, "sure it can."

The field is a multidisciplinary approach to solving financial problems. It borrows from subjects like computer science, economics, and mathematics. Financial engineering puts together a dream team of nerd pursuits to tackle issues related to finance using high-end math.

Part of the practical output of financial engineering is to develop new financial products. This bit of development has been a mixed bag, with the infamous mortgage-backed securities (the main disaster vector of the 2008 financial crisis) as one well-publicized result of financial engineering.

Finance: What are Valuation Analysis, Fo...4 Views

00:00

Finance Allah shmoop What are valuation analysis formats and ratios

00:11

It's a thing dot com It sells Who's ima wa

00:15

s Okay but investors want to know what percentage of

00:17

the company there ten million bucks will buy So somebody

00:21

has to know what it's worth and why There has

00:24

to be some exercise here which delivers an actual number

00:27

that says at this moment it's a thing dot com

00:30

is worth X Well in real life the most sophisticated

00:34

valuation format lives in applying a discounted cash flow analysis

00:38

model Yeah go watch are most excellent video directed by

00:41

Martin Scorsese on that topic If you haven't seen it

00:44

it won the Golden Mullah Award back in two thousand

00:47

eighteen Well if you haven't seen it the notion is

00:49

that company's heir valued as a stream of their cash

00:52

profits like into the future Cash profits Five million next

00:55

year Ten million The next eighteen million accents sold for

00:58

one hundred million the next Then all those cash flows

01:01

or discounted back or divided by one plus the risk

01:04

free rate I'ii uh you know the rent You could

01:07

get on your cash just by investing in U S

01:10

Government bonds plus risk Got it So that is risk

01:14

that the ten million of cash profits doesn't in fact

01:17

happen in real life like you're taking more risk than

01:19

you are investing in government bonds when you invest in

01:22

equities like this right So if the risk free rate

01:24

is in a three percent like a five year T

01:27

Bill or something like that then you might pile risk

01:29

on top of that of saying six percent or ten

01:32

percent or twenty percent a year And the certainty of

01:34

that ten million box in profits in two years changes

01:38

a lot and then that hundred million at the very

01:40

end Well it might have huge discounting like be divided

01:43

by one plus the risk free rate plus a huge

01:47

risk premium act on in the denominator making one hundred

01:50

million a very small number like it's very risky So

01:53

maybe that discount rate ends up being I don't know

01:55

say thirty percent added to the risk free rate and

01:57

it's four years out So it's taken to the fourth

02:00

power Yeah a lot of discounting that it looks like

02:02

this You got one point Oh three plus point three

02:05

Oh it's one point three three then to the fourth

02:08

power that you're going to divide into one hundred million

02:10

and give that a huge haircut But okay okay this

02:13

is a sophisticated Wall Street e way of valuing companies

02:16

There are simpler methods Multiples of sales is another one

02:19

that while people use And yes of course we have

02:21

an entire video on that one as well A company

02:24

has highly volatile profits like this is kind of company

02:27

that would use a multiple of sales valuation positive twenty

02:30

percent margins in great times negative fifteen percent margins in

02:34

bad times and an average over a decade of statement

02:37

of ten percent margins So on five hundred million of

02:39

sales it might on average have fifty million in net

02:42

profits and the average grows over time But the company

02:45

quote should unquote trade at a market multiple minus two

02:48

turns or something like that Or set another way if

02:51

the S and P five hundred straining at sixteen times

02:53

earnings well then maybe this crappy company that's highly cyclical

02:56

should trade it fourteen times Well fourteen times fifty is

02:59

seven hundred and note that that's about one point four

03:03

times sales Wealthy calculation then revolve around sales instead of

03:07

profits usually since year after year profits are yeah all

03:11

over the place where sales are relatively steady like they'll

03:14

go up three percent in Goodyear and down to percent

03:17

of badly or something like that So that's a multiple

03:19

of sales valuation format It's often used for early stage

03:23

companies who really don't have profits and would reinvest all

03:26

their free profits or cash into growth anyway So you

03:28

can imagine the same system applying to things like multiples

03:31

of gross margin for multiples of operating margin like pre

03:34

tax profits With the basic idea being that the closer

03:37

you get to the top line sales number usually the

03:40

less volatile those numbers on a year in year out

03:43

basis are and then the easier the valuation remains to

03:46

dial in structurally well cash flow multiples are good delimit

03:50

er zzzz Well think about how quote phantom depreciation unquote

03:53

works in clouding the true earnings Pictures of things like

03:56

a factory that cost a billion bucks to build and

03:59

is being depreciated to zero over ten years might carry

04:02

an earnings hit to the income statement of well a

04:04

hundred million bucks a year in straight line appreciation It

04:07

takes the eighty million in profits the company is making

04:10

toe being an accounting loss of twenty million dollars So

04:14

how does that work Well you thought you were making

04:16

eighty million in net profits but it turns out you've

04:20

got to depreciate one hundred million for that factory You

04:22

lavished Tobi right Well the cash the company produces is

04:26

its cash flow like from progressive Yet you know her

04:29

and backing out that appreciation gives a much clearer picture

04:32

of the company's expected profit ability in the future i

04:35

e Its value meaning you pay a whole lot more

04:37

attention to that eighty million dollars in profits Then you

04:40

do the twenty million in losses But this valuation method

04:43

becomes extremely useful in cases where that factory being appreciated

04:46

to zero in ten years will in fact last more

04:49

like forty years and even then not be worth zero

04:52

So we have discounted cash flow We have multiple of

04:55

sales We have multiple of cash flow And then of

04:57

course the stalwart multiple of earnings or price to earnings

05:01

ratio as a basic valuation format or racial or structure

05:05

that drives the lives of oh so many investments P

05:08

ratios are probably the most common evaluation metric Whatever dot

05:11

com will earn after everything appreciation included a dollar next

05:16

year a dollar twenty the following year and a dollar

05:18

forty the next It trades this moment for twenty bucks

05:22

a share or twenty times this year's earnings That's twenty

05:24

over one point two times next year's earnings twenty over

05:27

one point four times at the following years And yet

05:30

you get the picture It looks like that Well the

05:32

price to earnings multiple usually goes down over time because

05:35

well most companies actually grow their earnings over time The

05:39

Gatun here is that companies often carry cash and or

05:41

debt So if a company has ten dollars a share

05:44

in debt and four dollars a share in cash well

05:46

then its price to earnings ratio is while still twenty

05:49

But it likely has Mohr volatilities in its movements as

05:52

the debt is well kind of like gasoline on a

05:55

fire when things go well or poorly So yeah those

05:57

were the most common methods of assessing the value of

06:00

a company or a stock and you've got to take

06:03

all of them with many grains assault Although uh well

06:05

It's much easier if you just have one of these 00:06:07.671 --> [endTime] things to assess
