October Effect

Categories: Financial Theory

October is a spooky month. It ends with Halloween, obviously, but even besides that, it has an air of impending doom. Winter is coming, and all that.

This sense of pending foreboding manifests itself on Wall Street as well. It's called the October effect. The term refers to the perception that October is a bad month for the stock market...which may in part lead to October becoming a bad month for the stock market.

The main pillars of the Legend of October Scares comes from a handful of significant stock crashes in the month. Both the 1929 and 1987 market collapses happened in October. These events have made investors jumpy (even though one of those crashes is closing in on a century old), leading to a sometimes self-fulfilling prophesy of poor stock market performance in the month.

00:00

and finance Allah shmoop What was the market crash of

00:05

1929 aren't people while there was cheap and easy credit

00:12

and that's what the crash was really about Greed and

00:14

a big bad bear market nobody could have imagined happening

00:18

at the time right Nonprofessional retail investors were allowed to

00:22

borrow some 90% of their investment portfolio to go buy

00:26

new stocks beyond the stocks they already owned So quick

00:29

Math If someone invested $1000 of their own hard earned

00:32

savings and the stock tripled like it did in the

00:34

mid twenties for a lot of easy money yeah well

00:36

then that $1000 would have become $3000 in a very

00:40

short period of time Great but in fact margin rules

00:44

were almost non existent in era it was coming to

00:48

allow investors to have 334 even five times they're invested

00:52

equity as borrowed margin or set another way on an

00:55

initial $1000 invested Many investors were stupidly allowed to buy

00:59

$5000 worth of stocks So really volatile right If things

01:04

go the wrong way it hurts But let's take a

01:06

simpler approach If an investor had been allowed to margin

01:08

there account up to 90% of its value like 50%

01:12

is generally the maximum today that you could borrow Then

01:14

that investor on $1000 of their own invested capital could

01:17

have purchased $1900 worth of that stock that tripled So

01:21

doing the math three times 1900 gets you What is

01:24

that $5700 You pay back the $900 of margin that

01:28

you borrowed against yourself and you'll have netted something like

01:31

$4800 in profits albeit a little bit last because you'll

01:35

have paid interest to the brokerage's that allowed you to

01:37

borrow money in this manner That's a margin interests So

01:40

in the margin case while the $1000 ofyour invested capital

01:43

maybe 4.8 times your money rather of any paltry three

01:46

times your money had you not been leveraged and that's

01:49

way more dough to crow about right And in those

01:51

days well that extra $1800 would have bought you like

01:54

a house So everything was great 90 50 1926 27

01:57

28 when the market mostly generally went up and provided

02:00

easy money for the well heeled invest who could play

02:03

the game and everyone was incentivized to keep the party

02:06

rolling Yes that's a flapper girl Brokerages could charge fat

02:09

commissions on transactions and nobody complained Why Well because the

02:13

markets rise more than eight for those commissions Brokerages could

02:18

also charge big interest rates on borrowed margin because the

02:21

markets rise Masked all those costs and everything ended up

02:25

sweet and beautiful is the prince married the princess and

02:27

they went off to their castle in the clouds Oh

02:30

but wait Then reality struck One day a not so

02:33

kindly old woman offered Snow White the apple she bit

02:37

and the market went down down down Such that panic

02:40

selling ensued and more or less Everyone who was on

02:43

the hook to pay back borrowed money in the form

02:45

of margin had their loans called immediately by the kindly

02:48

smiling brokerages as they more or less lost while mohr

02:51

than everything meaning that not only did the investors lose

02:55

all of their investments but the brokerages who had underwritten

02:58

those loans themselves went bankrupt because the stocks went down

03:02

so far that even the margin limit covenants were violated

03:06

That is on the stock purchased $4000 with the $900

03:09

a margin That $1000 worth of stock ended up being

03:12

worth well $500 or maybe a lot less so even

03:15

if the brokerages sold every share of that original $1000

03:19

investment now worth only $500 While the $500 in original

03:23

value remaining didn't even come close to covering the $900

03:27

in margin the brokerages clients took out in loans in

03:30

the first place So yeah it sounds like the crazy

03:32

maddening crowds at work and the crowds back then were

03:36

mad Everyone was buying on margin and if you weren't

03:39

well then sucker you were just yet another sucker hauling

03:42

bricks or ice or railroad ties for a living Life

03:46

was way easier when you could just phone in a

03:48

stop order in you know play golf all day So

03:50

this was bad and 1/2 and it's part of the

03:53

process of investors panicking They lost trust in the financial

03:56

system of America Many investors then wanted to sleep on

04:00

a pile of their hard earned saved $20 bills so

04:03

they ran to the bank on Mass and asked for

04:05

their money back They wanted to withdraw all their money

04:08

from the banks And guess what The banks didn't have

04:11

the money sitting around because they loaned it out for

04:13

mortgages and car loans and horse loans or over the

04:16

head back then So the frame then was a failed

04:19

stock market Lack of trust in the banking system in

04:21

America no credit then offered Teo Well pretty much anyone

04:25

You can imagine what America would be like if we

04:27

didn't have credit cards alive and well and no adult

04:29

supervision to get this country out of the deep financial

04:32

hole that I dug well along came FDR With the

04:35

New Deal he primed the pump and creating federal guarantees

04:39

for banking deposits upto a little certain amount like FBI

04:43

see limits of 100 grand and change today He also

04:45

enforced vastly stricter regulations on banks brokerages and pretty much

04:49

anything financial such that going forward this country ran a

04:52

dramatically Mohr conservative balance sheets and investment people had to

04:57

disclose well pretty much everything The result Well gradually greed

05:01

came to overtake fear again and in mid thirties or

05:04

so the market slowly trundled northward again It's what I

05:07

look like And then everything gave rise Teo Well this

05:10

really beautiful sight Welcome to America
