Last Trading Day

Categories: Accounting, Trading

It might be "of the year" or "of the option expiry period" or some other construct where people care what that day is.

You are a pro trader, working for Goldman, making a cool mil a month in profit participation, albeit with extreme volatility, and it's October 27th. You're $287 million ahead in trading gains; you keep 10% of the trading gains you make in bonus money paid out over 3 years. If you do nothing from now until year-end, you lock in that $28.7 million bonus. So you care a lot about the last trading day of the year.

Same deal if you sold someone a call option to buy Disney at $120 and the stock is hovering at $118 right now. You have 7 days remaining until the last trading day when that option expires. So you pray for a choppy, bad down market, keeping Disney below that call, so that you can have taken in all the premium they paid to buy the call option, but you don't have to, um, actually do anything.

That last trading day...matters.

00:00

Finance allah shmoop what is a fiscal year versus a

00:06

calendar year Well let's start with the latter calendar year

00:11

that's this thing It starts january one with a hangover

00:14

and ends at midnight December thirty one with a big

00:17

fat ball dropping in new york No this thing different

00:21

ball paul's Never All right So that's a calendar year

00:24

and okay so what is a fiscal year And how

00:27

is it different from a calendar year Well it isn't

00:30

always different Actually a fiscal year just refers to the

00:34

one year period in which companies track and report their

00:37

financial story Some companies report from january one to december

00:42

thirty one right like their fiscal year maps on top

00:45

of the calendar year But in some cases this reporting

00:48

system was misleading or problematic for investors Why All right

00:53

Well let's take macy's please They used to be somebody

00:56

Somebody They had parades and white flower day sales and

01:00

people used to actually go to their stores So macy's

01:03

did some huge percentage of its sales for the year

01:07

right around christmas And before you know computers were really

01:11

a thing it often took weeks or months toe fairly

01:14

And accurately add everything up so macy's among others decided

01:20

to change their fiscal year They were powerful back then

01:23

so you know they could do things like that So

01:25

they moved their year to run from july one until

01:29

june thirty that is that became their fiscal year it's

01:33

still a year still three hundred sixty five days still

01:36

everything the same With the exception of the start and

01:39

end points this way When things were relatively quiet at

01:43

the end of june the macy's bean counters could properly

01:47

count their year end beans in relative peace and harmony

01:50

Having caught up from the day luge of frenzied christmas

01:54

sales it gets even more complex in that some companies

01:57

wanted to be fully off kilter for any comparable calendar

02:02

years Oracle the database company for example is one of

02:05

them Savvy buyers of databases would wait until just before

02:10

the quarter ended for oracle hoping to negotiate better rates

02:14

in renting their database needs It was dangerous for a

02:18

company to miss its quarter with so much competition in

02:21

silicon valley from startups to steal those precious engineers from

02:25

big companies and put him into running a startups You

02:28

know big companies and they paid in cash and modest

02:31

stock options You can't really get rich these days working

02:34

at oracle if oracle ever missed a quarter while it

02:37

would hemorrhage engineers to the venture capital people hovering in

02:40

the hallways so oracle moved its fiscal ofthe month I'ii

02:44

february may august november kind of vibe so that wouldn't

02:49

be quite as held hostage by those savvy database renters

02:53

hoping for a macy style midnight white flower day sale

02:57

Now that's something worthy of a parade There's a database 00:03:00.715 --> [endTime] parade
