Portfolio Return

  

Categories: Metrics, Managed Funds

See: Internal Rate of Return - IRR.

A given portfolio produces a return (hopefully that return is positive and high, numerically).

How do you calculate the return? Well, from start to end, remember the magic formula: New minus Old, all over Old. So if the portfolio was worth $100 million when you started, and 5 years later it was worth $180 million, then you'd calculate by taking $180 million (new) minus $100 million (old) which is $80 million, over Old...which (again) is $100 million. So the total return over 5 years is 80%.

of return a dollar today is worth more than a

00:10

dollar tomorrow Like that's the central prayer of the financial

00:15

force Here's the gist You've double your money in an

00:17

investment Is that good Bad ugly mon We need a

00:20

whole lot more information here Tto answer Did you buy

00:22

thirty eight million and two dollars worth of lottery tickets

00:26

and that last two dollar ticket got you seventy six

00:28

million in winnings Was that like a good investment Or

00:33

how about this You took thirty six years to double

00:35

your money Was that good I answer to both No

00:38

not at all The lottery ticket example is a risk

00:42

waited return The lottery famously takes advantage of ignorant people

00:46

spending their hard earned money on tickets representing dreams but

00:50

which have horrible odds of any kind of decent pay

00:52

back But the lottery makes go into a vegas casino

00:55

look like actually a good deal so you may win

00:58

but it's a bad risk no matter how you look

01:00

at it And hey somebody has to pay those teacher

01:03

pension bill So why shouldn't it be people who didn't

01:06

graduate high school Right Well the time waiting is a

01:09

big deal to in a world where the stock market

01:12

broadly speaking doubles on its own About every eight nine

01:15

ten twelve years Something like that This calculation is done

01:18

over very long periods of time and it's held true

01:20

for about a century and change in america So if

01:23

he took thirty six years to double your money well

01:26

it implies you only made two percent a year as

01:28

your rate of return Remember that rule of seventy two

01:31

thing Yeah that right there Seventy two divided by thirty

01:33

six and you get a whopping two percent return Well

01:36

in that same period of time the market might have

01:38

doubled in four times So the ten grand that double

01:41

to be twenty grand in thirty six freakin years under

01:44

your watch we'll have you just put it into an

01:47

index fund of the s and p five hundred over

01:50

that same time period Well it would have doubled once

01:52

along the timeline here to be twenty grand then doubled

01:55

again here to be forty grand and then doubled again

01:58

here to be a tigre rine and then ah forthe

02:01

doubling right here after thirty six years maybe one hundred

02:04

sixty grand And that's just an index fund Nothing fancy

02:07

Not warren buffett Just a basic vanilla index fund that

02:10

anyone with two hundred fifty bucks in their pocket can

02:13

buy And it's worth noting dividends which often get ignored

02:17

in the financial press actually matter a ton when it

02:19

comes to the calculation of long term investment results Generally

02:22

speaking that continued payment of dividends is a low risk

02:25

adventure Very few companies ever cut or fully do away

02:28

with their dividends And if they do well it means

02:31

a pretty much everything is rotten in denmark so you

02:34

can count on dividends The bolster overall returns that historically

02:37

dividends have had a wide range of somewhere between two

02:40

and seven or eight percent for the mid range of

02:43

the s and p five hundred But if you pegged

02:45

them around and three ish percent today and changed to

02:47

reflect the modern era well then the overall market need

02:50

only compounded about five percent To deliver that five plus

02:54

three percent and change eight ish percent total returns That

02:57

will allow the stock market to double about every nine

03:00

years or so right so we're ignoring taxes here but

03:03

we're ignoring the use of dividends proceeds to buy more

03:05

shares every quarter as well when those dividends air paid

03:08

So when you think about time and risk think about

03:10

them like they're a kind of financial stone soup which

03:13

when mixed together with the right spices of tax hedges

03:16

leverage and a bull market well make a really nice

03:19

retirement meal and you don't even need your teeth on 00:03:22.773 --> [endTime] a bonus
