Hey everyone.
[1]
This is Kirk, here again at optionalpha.com where we show you how to make smarter trades.
[6]
In today's video, we’re going to cover a huge topic and that’s short strangle adjustments.
[12]
Short strangles are very high probability neutral trades with options far out of the
[17]
money, so it’s first important that you have a set of rules in place to avoid over
[22]
adjusting.
[23]
We have some guides inside of optionalpha.com that you can download as members that give
[28]
you an idea of when to adjust and how far to adjust things like that, but we’re going
[32]
to go over an example, a classic example today as we get through these slides.
[36]
That said, if the stock moves towards one end of the strategy quickly, you’ll want
[41]
to first adjust the side of the strategy that the stock is moving away from by moving that
[48]
option closer.
[49]
Again, on our chart here, this is what we’re going to do.
[53]
Once we see that we have this strategy here and we’re neutral, if the stock is in between
[57]
our strikes as we enter this trade or fairly neutral and the stock starts sliding one direction
[65]
or another, what we’re first going to do to make an adjustment is take one side of
[70]
the trade, in this case, we’ll take the put side and we’re going to roll that side
[74]
closer to the money.
[77]
Basically, what we’re going to do is we’re going to slide this side over and it's going
[81]
to make this profit loss diagram much taller and much wider and that’s going to help
[87]
even out our breakeven points.
[91]
For simplicity, let’s assume that you sold options on either side of the market at a
[95]
15% probability of being in the money level which is about a 15 Delta and we’re going
[101]
to replicate this trade later on.
[103]
But one of the ways that we adjust is that we'll look to adjust one side when the short
[108]
strike increases to a 30 Delta.
[112]
We’ll place the trade when we have about a 15 Delta on each side.
[116]
If that Delta then doubles, so our probability of losing basically doubles to a 30 Delta,
[123]
we consider that probably a good time to make an adjustment to this strategy.
[128]
What we would do in one case if the stock is moving down towards our put side, in this
[135]
case, if the stock is moving lower towards our put side, then we would adjust down the
[141]
call side of the trade closer to the stock price and take in an additional credit.
[146]
You can see this is what it would look like.
[147]
We would adjust this side closer to the market and this new strategy here is in the dotted
[153]
red line on the graph.
[155]
Now you can see it's a much taller payoff diagram, it’s much taller because we took
[160]
in additional credit and the breakeven points are out just a little bit wider, kind of really
[166]
reflecting the new value of the stock and trying to rebalance and reposition the strategy.
[173]
One key point here is that when we roll down this call side, everyone always asks, “Well,
[178]
how far do I roll down that call side?
[181]
How close to the market do I want to get?”
[184]
We always say that we try to reset the probability on this side of the trade to a 15 Delta.
[189]
When you originally entered the trade, it had a 15 Delta.
[192]
As the stock is dropping, the Delta of that strike price is also dropping.
[198]
It’s no longer a 15 Delta because the stock is moving away from that strike price.
[203]
We try to reset that probability and that gives us just a good road-marker or a guidepost
[208]
to use when we’re trying to decide how far down to roll that side.
[214]
Another key point here is make sure that you match the number of contracts during this
[218]
roll as this takes on no additional risk with your broker.
[222]
If you have one put option and one call option in your strangle, you want to make sure that
[227]
when you roll down that one side that you still have one put and one call when everything
[231]
is done and over with.
[233]
If you have two, then you want to make sure you still have two on either side when you
[236]
roll it down.
[237]
This takes on no additional risk for your broker, but that increase in premium helps
[243]
offset some of the potential loss on the trade and helps widen out your breakeven points.
[248]
Let’s actually go here to the Thinkorswim platform and take a look at an example right
[252]
now.
[253]
This is just a simulated trade that I put on today in SPY.
[258]
You can see SPY right now is trading about 205.48 and I decided just for the sake of
[265]
starting this that we’re going to sell the 214 call and the 187 put on either side of
[275]
the market.
[276]
Each of those sides is at about a 15% probability of success.
[281]
You can see the market is moving a little bit as we’re doing this video, but you can
[285]
see this 214 call is right at about a 15%, about 2% higher, and on the bottom side, the
[292]
187 is right at a 15% probability of being in the money, so a probability of losing.
[298]
That’s how we’re going to place this trade.
[302]
You can see the risk profile here, it’s slightly skewed to the downside and that’s
[305]
just because the probability of the stock dropping faster is a little bit higher, but
[309]
this is a balanced trade because of the probabilities being even on either side.
[314]
In this case, you can see our breakeven points are right about here and right about here
[319]
and with the stock right here, it’s just a little bit skewed to the downside, but there
[323]
is more risk that the stock falls faster than it rises.
[327]
In this case, we take in about a 210 credit.
[329]
We’ll just keep the numbers pretty simple here.
[332]
We take in about a 210 credit on this trade which helps widen our breakeven points out
[337]
$2.10 on either end of the strike prices that we select.
[343]
Let's assume here that the stock continues to fall.
[347]
It starts falling and it starts falling really fast, really hard.
[351]
It’s starting to move away from our call side and it’s starting to challenge the
[356]
put side of this trade.
[358]
What we said is that if that Delta of the option goes from about a 15 to a 30, (you
[366]
can see here that right now, it’s about a 15% probability of being in the money) that
[372]
means that this probability here would have to go to about a 30% chance of being in the
[378]
money for us to make an adjustment.
[380]
The stock has got to move down that far, that fast for us to be able to make an adjustment
[386]
on this trade.
[387]
You can see with the other probabilities here that a 30% probability right now is about
[393]
197.
[394]
Basically, after about a $10 drop is when we’d be looking to make an adjustment to
[400]
this trade because right now, the 197s have about a 30% chance of being in the money or
[406]
losing, and if our trade were to be a 30% chance, that might be another $10 drop from
[412]
here.
[413]
You can help yourself guesstimate and estimate how far the stock might have to drop for that
[419]
to happen.
[421]
Let's say that the stock does drop $10 from where it’s at right now which is 205.
[425]
We’re just going to move this over here and we’re just going to drop this $10 all
[430]
the way down to 195.
[432]
Let’s say the stock moves down to about 195 which is about here.
[438]
Now, the stock is challenging the put side of our trade.
[441]
Now, this side of the trade is starting to win money.
[444]
What we want to do is we want to roll this side closer to the market.
[449]
We’re going to roll this side closer, try to rebalance the position over where the market
[454]
is trading right now.
[456]
This is going to do two things.
[457]
It’s going to bank a profit on this side of the trade because it's moving away and
[461]
it’s going to help move out our breakeven point by the amount of the credit that we
[466]
take in on this roll.
[469]
If we roll this side down closer, we’re looking to make a more narrow (and I’ll
[475]
just draw it out here in dotted line) strangle that is a little bit higher in premium which
[483]
helps move out our breakeven points.
[486]
Again, we’re trying to roll this call side down to the market.
[489]
We’re not touching this put side.
[492]
We’d never touch the side that the market is moving against.
[495]
That side is already losing.
[496]
We don’t want to roll that side down because that means we just get ourselves into a situation
[501]
where we can start compounding losses.
[504]
Logistically, what that would look like if you did decide to roll this side down is you
[509]
would enter that trade as a vertical credit spread.
[513]
If we already had a position at 214, we could enter a position let's say at 210.
[521]
We wanted to roll it down to 210 and we would make a sell order and we would sell the 210s
[528]
and we would buyback our 214s that we are short.
[533]
You can see here that 214, we’re going to buy those back with a vertical spread order.
[539]
That one contract that we buyback is going to cancel out those 214s that we were originally
[546]
short.
[547]
In this case, you might not take in $133 because that’s live pricing, but let’s say you
[551]
take in about $80 on the roll down.
[554]
The difference between selling the new 210s and buying the new 214s gives you about an
[562]
$80 credit additional to the 210 credit that you received originally.
[568]
Now you’ve got a total credit of $290 and that's what helps widen out the breakeven
[575]
points on this trade.
[577]
Now that we’ve made this trade and this adjustment, you can see what this new profit
[581]
loss diagram would look like here.
[583]
You can see that now we have the 210s, so our option strategy starts to move this way
[588]
and it’s a little bit more balanced over the market and you can see that our breakeven
[594]
point did in fact move out just a little bit further.
[596]
It’s helping this breakeven point move out further which is why we just continued to
[601]
roll down the call side.
[603]
As the stock continues to move lower, you'll just keep moving down that call side as much
[608]
as you want or as little as you want.
[609]
We can keep moving it into 208 and you can see we can just take in more and more credit.
[614]
We can move it down to 205, take in a really big credit, maybe $200.
[618]
But you can see the closer that you move this stock, the more credit you’re going to take
[623]
in and the further out you’re going to move those breakeven points.
[628]
You can get carried away with making these adjustments.
[630]
We definitely suggest that you adjust that call side down to a level which is at about
[638]
the same probability level that you started with.
[642]
Whatever the new 15% out of the money level is or 15 Delta is, that's where you want to
[648]
adjust.
[649]
You don’t want to adjust too far down from there or else you’d get caught if the stock
[653]
does make a reversal and turns around the other way.
[656]
Alright, wrapping up here with short strangles, the new more narrowed and taller strangle
[662]
as we have shown you helps widen your breakeven points on the trade and more importantly,
[669]
helps re-center the trade over the new stock price.
[673]
That's really our goal of making this adjustment.
[676]
We want to recognize that the stock has made a move lower, try to make an adjustment that
[682]
takes into account that new stock price and try to re-center the trade over the market.
[688]
This will work in the complete opposite.
[690]
If the stock moves against you towards the topside of your trade, so if it starts moving
[695]
towards the call side, you’ll want to roll up that put side to about a 15 Delta and re-center
[702]
the strategy that direction, not touching the call side, but rolling up that put side.
[707]
Hopefully this has been a really, really helpful video.
[711]
This is a huge question that we get, but this is exactly how you do it.
[715]
There’s nothing more complicated than this.
[717]
It’s a very simple strategy to do.
[720]
You just have to be diligent about setting those rules in place about when you’re going
[724]
to adjust and how for you’re going to adjust ahead of time before you make a strangle trade.
[729]
As always, I hope you guys enjoy these videos.
