Aren't options risky?wayneL said:Any questions are welcome.
cuttlefish said:The only thorn in the side of this argument is liquidity (contest risk as you call it?), which I don't think can be dismissed (and you've of course mentioned it as well in the first post but glossed over it).
It means you aren't guaranteed to get the 'theoretical price', all you get is a spread unless its a highly liquid options series - this unfortunately typically means no more than a couple of months out and pretty close to the money.
But if you trade in underlying stock you do get the liquidity and don't have to worry about this.
cuttlefish said:This is a concern if taking large options positions - similar to the concerns someone would have taking large positions in an illiquid stock. If you want to get out in a hurry you will pay a price - maybe a big price.
cuttlefish said:Are there any strategies for dealing with contest risk (assuming I've understood this term correctly)? Also has this cost been quantified?
cuttlefish said:thanks for the reply. I guess something I've found in my experimenting with options is that the reality is that contest risk (or the cost of the spread) is real - you might be able to negate it on one side of the trade (e.g. only enter when you're not paying it - effectively means only entering when you're buying from another trader rather than an MM) but you can't guarantee it on exit. (and yes you can increase your chances of not paying it on either side if you pick a liquid option).
To me in the illiquid Australian market this limits the variety of choices available in using options - almost to short term trading rather than taking longer term positions. I'm still experimenting at using long ATM calls (or near atm calls) for long term investing types of positions but am aware that I'm paying a contest premium when doing it, and also don't have the ease of exit I would with a long term position by directly buying the stock - so if I need/want to exit in a hurry I might have to give away a fair bit of theta and delta (and if it wasn't for the arbitrage traders I'd be giving away a lot more.).
For this reason I'm not that confident about using them to synthesise the equivalent of a large investment in the underlying.
I guess the other way of doing it is to use reasonably deep ITM's to synthesise the long position in which case there isn't as much theta and vega built into the price - but to some extent that defeats the purpose - it would be possible to achieve similar by directly buying more of the underlying using margin and I'd probably pay less carry cost overall.
I know I can also short puts to take long term positions, but I'm talking about low volatility stocks and my understanding so far is it is probably better to short options when you think volatility is going to reduce and long them when you think it will rise.
I'm at the very early stages of learning this stuff, so finding it interesting to talk and think about it and also by trying it am learning a lot that you can't learn via the reading etc.
I've found a lot of the comments on here helpful, particularly discussions on the greeks etc. in the options mentoring thread, and am pretty sure they've resulted in an increased success rate so far.
wayneL said:Said another way, if six separate traders each entered one of the above positions, each trader would either end up with either a profit or a loss, of varying magnitutes. However, if the profit or loss of all six traders were added together, the result would be 0, NO MATTER WHAT THE STOCK PRICE DOES.
wayneL said:Even low IV stocks cycle from relative lows to relative highs. The lower quartile in the IV range is the time to put this on.
In comparing it to a margined stock position, once again, trade offs. You effectively have NO downside protection in this position if the stock is subject to a large gap down.
hissho said:hi Wayne
Glad to see another good thread on options!
here's my question: sometimes you can find arbitage opportunities in conversion, box spread and reversion etc.....
1) how does that happen? because of a mistake made by MMs?
2) how would you capture such a risk-free opportunity? sitting in front of your computer all day and search? or you set up your software in some way so that you'll get a pop-up window when the opportunity presents itself?
thanks
