I was wrong in one of my earlier posts about volume reseting daily(like it does daily on a stock or ETF). It looks like it doesn't so that volume is
still there. So I've learned something new.
The spx.x options chain tracks the index while the other tracks the SPY etf. They're basically tracking the same thing except it'll take 10 times
the money to buy an option on the spx.x as it would to buy one on the SPY. Oh, and in case you didn't know a single option represents 100 shares of
the underlying asset. So you multiply the ask price by 100 and that's what it would cost to get a single option (on 100 shares) that's also why i
use limit orders when i buy anything but that's another issue entirely). For example if i wanted to buy a call (expecting market to go up) on the SPY
at the $150 strike i'd pay $165 per call + transaction costs (usually about $11 +$.75 per contract). If i wanted to buy a call option on the spx.x at
the same 1,500 level it would cost $1,530 per option plus transaction costs.It can be said that 10 SPY options = 1 spx.x option and ther would be 1000
SPY stock as the underlying asset. That last two sentences may be confusing but i'm nearly certain i'm right there. If i wanted to sell those calls
I would get the same amount credited to my account.
After typing that I realize mesh said basically the same thing. It interests me greatly. No one teaches this stuff. I will definately be using that
site instead of yahoo from now on to track options that interest me, it's so much easier to see the two side by side. I've been leaning toward some
type of trade with two sides since the beginning, I guess now the question is who is so hard up they did this to raise cash.
There still seems to be a huge amount of short interest on the S&P though, after what the fed did last expiration day i'd be scared of shorting too
hard.
