Smurphy most people can invest without using options, also if you are doing very short term trades probably options would not be used.
quick examples
Royal Bank (canada) option on Montreal
current price Royal Bank $55.56
RY Call $54 Oct 3.60-4
so this allows the buyer to buy Royal Bank for $54 up until the third friday in October. for this pays 3.60-4 a share (1 contract = 100 share=$360 )
the seller recieves $360 (and all dividends, if they hold the stock). however must sell it if goes over $54.
PUT
let us say you believe Royal Bank will tank, (not sure why but this is an example)
RY P $54 oct 1.60-1.95
so the seller believes Royal will go higher or stay above 54. and sell the put (100 shares /1contract $195)
the buyer believes Royal will tank so buy a put $54 oct. for 195. this allow the buyer to sell Royal bank at 54 until 3rd friday in october.
so if royal falls to 45. you would make a good profit.
US examples
Home depot HD
$38.64
Puts
MAy P 37.50 .95-1.05
you hate retail and you believe the housing market will only get worse. you could buy a put that allows you to sell for 37.50.
until 3rd friday in may.
this will cost you $105 dollars, or 95.
just a few examples, actually the prices for some options have gone up, I guess a sharp sell off does that...lol.
the options are priced on time and how volatile the stock/index is...... this makes sense.
an investor would be more willing to pay a higher price for a volatile stock. stocks that fit this bill are base metal companies, energy, techs, ect.
low volatile stock will have lower premiums ie. utilities, banks, ect.
will post some of my options here so people can track them and see how many get wrong.
for the most they do well, wrote one this week wish I had back....
thanks
