To figure out what calls are all about, we first have to understand options trading. There are two kinds of options: call options if you want to predict the price of an asset will go up within a period of time, or put options where you predict the price will go down.
With us so far? All options have an underlying "instrument" that could be a stock, bond, commodity (corn, wheat, etc.), or foreign currency. Traders, also called "writers," sell call options on a stock, for example, and set a "strike price" (what price the stock must reach) for a particular time period.
For a call option, another trader buys the option, giving him or her the right (but not the obligation) to buy a specific number of shares at the strike price within that timeframe. If the buyer of the call option does decide to "exercise" (buy) the shares, the seller has to deliver them. When the strike price is less than the market price at the end of the agreed-upon timeframe, the buyer would most likely decide not to exercise the option, and just let them expire.
Let's say Alice owns 12,000 shares of Call Me Happy, Inc. that are valued at $5.00 a share. With all that is going on in the economy, she starts to worry that the price will go down in the relatively near future. So she decides to protect herself and decides to sell a call option to Richard, who thinks the price will continue to go up. Their contract states that Richard can buy Alice's 12,000 shares six months from now at $6.00 per share. If the market price is only $4 at the end of six months, Richard will no longer be interested and they will let the call option expire.
However, if the stock rises to $7 a share, Richard can exercise his option, buy the shares at $6 and pocket the profit.

Finance: What Is a Put Option?83 Views
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.
