A group of securities whose overall value is determined by giving equal weight to each security’s performance rather than weighting by other factors like its market weight (think Nasdaq 100) or price weight (the Dow Jones).
It’s nothing more than a straight-up, vanilla average of the performance of all the securities in the index. Like if we have in our index 1,000 shares of GE at $15 and 2,000 shares of MO at $58 and 5,000 shares of AAPL at $200, even though the weighted average in the index of AAPL is way more than the other stocks in there, the arithmetic index ignores the weighting. It just takes the plain jane average of 15, 58, and 200 and reports what the arithmetic mean index did.

Finance: What is Compounding Value or Co...1773 Views
Finance allah shmoop What is calm Pounding value or compounding
interest Ah the power of compounding it makes tree's stronger
pollution More feral and the rich Well richer How so
Well let's start with compounds kissing cousin with six toes
Arithmetic calm pounding Right So the first was really geometric
compounding Now we're talking about arithmetic compounding If you invest
a thousand bucks in a ten year bond that pay
six percent a year in interest the dough comes back
to you in a pattern that looks like this Like
every six months they pay thirty bucks and it's sixty
dollars a year Got it nice You get the total
of sixteen hundred bucks back from your investment And the
cash that came back to you you know came in
small parts all along the way until you got about
two thirds of it or sixty percent at the end
right If you just spent that money and collected your
thousand bucks at the end That's it Okay So that's
arithmetic compounding the money comes to you You don't reinvest
it Ding ding ding that's the key here and you
just go buy burgers Okay So now let's look at
what six percent compound id looks like over the same
ten year period Wealth at the end of your one
it's a thousand sixty bucks and no we're only going
to compound it annually We probably should do the semi
annually but we confuse you even more is we won't
do that but then you essentially re invest that money
and you get another six percent compounded on that thousand
sixty instead of six percent compounded against the original thousand
so by the end of your two you'll have a
thousand one hundred twenty three sixty and by the end
of your ten you'll have one thousand seven hundred ninety
dollars and eighty five cents So why do you make
so much more money when you compound interest versus getting
thirty bucks twice a year like you would in this
bond example going by and burgers with it You don't
wanna do that well essentially what's happening is that you're
delaying your gratification of getting that sweet sweet cash or
getting liquid Whatever you wanna call it by reinvesting your
gains year after year after year So do you have
that sort of self control Do you need the cash
Yeah that's The question If you for example have trouble
making it home from your local pizza spot with the
pie intact well and compound interest Keeping the discipline to
not spend the money today and wait for the happiness
tomorrow Well when that may not be for you Sorry
