The evil twin of arithmetic nice. A fancy term for the average of a group of numbers. Yeah, seriously, you add up all the numbers and divide the total by how many numbers you have.
In three consecutive months, we showed percentage returns of 3.2%, 1.7% and 0.05%. Our average return over those three months can be found by adding 3.2, 1.7, and 0.05 to get 5.4, and then dividing that by 3 to get an average return over the three months of 1.8%. That’s all. Move along. There’s nothing more to see here.

finance a la shmoop. what is the S&P 500? well the S&P 500 is just an index- that
is the standard and poors company assembled 500 stocks put them on a
spreadsheet- this was a spreadsheet in 1957 -and they tracked them. [spreadsheet pictured]
well the index had something like 37 shares of Procter & Gamble, the 23 shares
of Ford, 18 shares of IBM and so on. in the 1950s the S&P 500 totaled something
like 40 maybe 50 bucks on a good day. at the end of each day the elves who worked
inside of the S&P Factory, they would add up the shares basically ignore any
dividends and send to the press a total which was published to more or less
everyone who cared about investing. well not nearly even a century later the 40 [man reads newspaper]
to $50 reign to the SNP is today knock on the door of 2,500 .so without even
having dividends reinvested you'd have made 50 times your money with dividends
reinvested to buy more shares instead of keeping the cash to buy you know
groceries or electric massage slippers. you'd have made over 70 times your [grocery display case and slippers pictured]
original investment. welcome to America.
