Apparently, there's a Tapo District in Peru. There's also a Tapo language, which is spoken in sections of Ethopia. None of that has anything to do with this definition, however. We were just planning our next vacation and had all these Tapo-related notes ready to go.
This TAPO has to do with the options market. The name stands for "traded average price option."
To explain how it works, let's take a look at how regular options work. Most options pay off based on the difference between the price of an underlying asset and the strike price of the option.
You hold an option to buy 100 shares of AAPL at $200 a share. The day the option expires, AAPL finishes at $220. The $20 difference defines the the profit from the option. That situation describes the usual setup.
A TAPO works differently. Instead of the single trading price for the asset, the profit and loss get determined using an average price. For a TAPO, it doesn't really matter much that AAPL traded at $220 at expiration. If it had an average price of $190 over the course of the time period in question, the option would be worthless. You'd just let it expire without exercising it.
The option's value gets determined by the difference between the strike price and the average price. So if AAPL closes at expiration at $220, but has an average trading price of $210, then the profit for that option is $10...not $20. The key stat is the average price, compared to the strike price.

finance a la shmoop what is a put option? hot potato hot potato
ow ow! yeah remember that game well nobody wanted the potato, poor thing. the
players wanted to put it in someone else's hands. well put options kind [glue put around a flaming potato]
of work the same way. a put option is the right or option or choice to sell a
stock or a bond at a given price to someone by a certain end date.
all right example time. you bought netflix stock at the IPO a zillion years
ago at $1 a share. that's you know splits adjusted. all right now it's a hundred
bucks a share. if you sell it you pay taxes on a gain of 99 dollars a share. in
California that would be a tax of something like almost 40 bucks. well the
stock was a hundred but you keep only something like 60. feels totally unfair.
right so you really don't want to sell your stock but you're nervous about the [graph shown]
next few months that Netflix will crater for a while and go down ten
maybe twenty dollars. longer term though you think it'll hit 300. so this is the
perfect setup to maybe look at buying some put options on Netflix. if the stock
goes down your put options go up. with Netflix volatile but at a hundred bucks
a share ,you look up the price of an $80 strike price put option expiring in
December, and you know that's mid-september now .for five bucks a share
you can protect your stock for the next few months .think about it like temporary [stocks placed in vault]
term life insurance. you pay the five dollars a share in the stock goes down
to 82 by mid December, worst of all worlds. well not only did you lose the $5
a share but your stock has lost $18 in value. but had Netflix really cratered
and gone to say $60 a share well you would have exercised your put and sold
your shares at 80 bucks. well those put options you paid $5 for
would be been worth 15 bucks a share. in buying that put option you've [equation shown]
guaranteed that your loss will be no more than a $75 value for your Netflix
position at least for that time period and ignoring taxes. well remember that
options expire after December whatever like the third Friday of the month it's
usually when options expire, you then have no protection and your shares float
along naked. naked? really who knew accounting could get so [paper put option goes "skinny dipping".]
raunchy. yeah well that's naked put options.
that's what they really are people.
