Finance allah shmoop What is a market maker What is

00:07

a market maker Hint He comes right after the butcher

00:11

and the baker Okay so you have lots of buyers

00:14

and lots of sellers and they come together a g

00:17

rated lee in a market which is so big it

00:19

has to be divided into segments or sections or sub

00:22

groupings of aa few stocks or bonds in which the

00:25

specialist trades and that specialist volunteers there time because they

00:30

loved it well actually know that not all true they

00:32

get paid a lot Ah lot When things go well

00:35

how are they paid Well through spread and not the

00:38

warm butter kind Instead spread refers to the money value

00:42

between a bid and an ask price under a market

00:44

maker structure of trading securities No more wire hangers a

00:52

plastic hanger company is publicly traded on an exchange like

00:56

nasdaq where buyers bid for a price to purchase and

01:00

sellers asked for a price to trade no more Wire

01:04

hangers is bid this moment at thirty seven twenty three

01:07

a share by buyers willing to pay by right now

01:10

at that price and is being asked at this moment

01:14

at a price of thirty seven thirty one Note the

01:16

eight cents a share difference in the share prices that

01:19

def is the spread between the two prices and it's

01:23

worth noting that in extremely volatile stocks the spread widens

01:28

and in boring highly liquid stocks which don't move much

01:32

the spread titans or is narrower that is on a

01:36

volatile equivalent of no more wire hangers The spread might

01:39

grow to twenty or thirty cents a share whereas a

01:42

boring name that pays a big dividend and the stock

01:45

never moves much We're thinking t here well that spread

01:48

might be just three or four cents So why grow

01:51

Well Because a market maker in a volatile stock doesn't

01:54

want to be caught losing money on her inventory The

01:58

market maker never once to be punished for providing liquidity

02:02

and market makers provide liquidity for stocks bonds and well

02:05

basically anything else they think they can generate revenue from

02:08

spreads in If no more wire hangers suddenly gap down

02:12

to thirty seven Ten a share Well it would be

02:14

likely less than the average of what the market maker

02:18

pa paid for her quote inventory unquote in that stock

02:21

from which he was making a market in it Each

02:24

time the shares trade the market makers dip into that

02:26

spread to pay their bills and allow them to keep

02:29

doing business So that spread and it's not the type

02:32

that prince used teo sing about Okay so then specifically

02:36

what's a specialist i wouldn't have a movie Stallone wait

02:41

different kind of specialist in finance land a specialist is

02:46

the gala guy trading in a given stock that is

02:49

there a member of a stock exchange and they might

02:51

carry inventory of satan Ten million shares of microsoft trading

02:55

currently at around forty bucks a share Their offering msft

02:59

for sale it forty point oh five and they're our

03:02

buyer of msft this moment at thirty nine ninety one

03:06

and see there's a fourteen cents a share spread their

03:09

meaning that they make fourteen cents every time they transact

03:13

So let's say that specialist sells a million shares of

03:18

microsoft today earning a fourteen cents spread per share while

03:22

fourteen cents times a million one hundred forty grand and

03:26

clown Nice a day for one day's work so that's

03:29

a pretty widespread in the scheme of things because often

03:31

brokers have to tack on their own commission of a

03:34

few cents on either side and the specialist might in

03:37

fact be dealing from their inventory to brokers on both

03:41

sides of a transaction in which case they're spread I

03:45

even spread to the actual specialist might be just a

03:48

few cents times those million shares like four cents times

03:51

a million gets forty grand something like that It's still

03:53

a really good living But if it's so good then

03:56

why don't millions of people fight for that job Like

03:59

how hard it is Is it tio Just nod your

04:02

head and right down buy or sell and then a

04:05

number You think everyone who flips burgers at mcdonald's and

04:08

is afraid of robots taking their jobs would be killing

04:11

for this gig Well in order to be a specialist

04:13

Not only do you need you know special education and

04:17

a few siri's license exams but you also need capital

04:22

with which to buy inventory risky inventory which you'll hold

04:26

as if they are casino chips and you are more

04:29

or less the house So when the microsoft shares example

04:32

just to be a specialist in that one stock well

04:35

you have to raise something like one hundred million dollars

04:38

because you'll have to go into the market to start

04:41

and simply by you two or three and call two

04:43

and a half million shares at around forty bucks each

04:46

for a total cost of ahhh ondo or a silicon

04:49

valley unit That's What units called out here And yes

04:52

that's an investment in the stock could go up but

04:54

it could go down as well leaving you holding a

04:57

big fat smoldering bag of dog crap dot on and

05:01

also going whoever your investors or creditors workout one hundred

05:05

million dollars Like if microsoft has kind of evaporated you

05:10

know what could happen More risks will haunt your sleep

05:12

in that the stock and suddenly gap down three dollars

05:15

on a bad quarter at which point Your spreads must

05:18

widen to accommodate expected further volatility in the stock And

05:22

you then compete with other specialists who also make a

05:25

market in microsoft Well at any given time they may

05:28

want to go get out of trading in it and

05:30

undercut you Buy any or to a share leaving you

05:33

as the sole big owner of what will feel like

05:37

a stock version of the titanic Well the math gets

05:39

complex is the market gets volatile specialists use hedges and

05:43

human beings end up competing against a i'd driven black

05:47

box computers But the reason you exist as a specialist

05:51

or rather the key job or responsibility of the specialist

05:55

is to provide liquidity That is you have to buy

05:58

and sell shares too Accommodate hey the market that's your

06:02

job and in volatile markets it means that they might

06:05

run out of inventory or be squeezed and have to

06:08

buy shares at much higher or sell shares at much

06:12

lower prices than their costs But that's the risk you

06:15

take when you become a specialist they must execute on

06:18

these trades and if they don't they lose Their seat

06:21

Is a specialist on the exchange altogether and are more

06:24

or less fully out of work And you know i

06:26

don't know Working for uber lift or something Next Yeah

06:29

And at that point well they might be willing to 00:06:31.755 --> [endTime] take just about anything for a ride
