A long Vega trade in OEX

Posted by: Admin: "The Vol_Trader"  //  Category: Trade strategy, Volatility Trades

It’s rare that I am completely or mostly ‘out of the market’ but this is one of those times.  I tend to travel a lot in the summer and when the market cooperates I like to take profits and leave the city with small to no positions on to worry about.  On vacation I like to log on to Thinkorswim no more than once or twice a day.  With the recent downturn in the markets I have done very well and took off lots of profits…

However, going into the Independence day holiday vacation for a week, I can’t resist having some short delta trade on.  I really think we are going to give back a few more months of gains from the previous year long rally.  As my friends and readers know I never believed in the rally from March 2009. 

So, I want a low maintenance trade that I can look at once or twice a day on vacation that requires little to no work.   I would have liked it to be Theta positive but it starts off short Theta. 

Trade logic:

  • I want to be short delta but have protection to the upside. 
  • I want to be long Vega but not get hurt too badly if the market goes up and IV drops.
  • I want to have a limited risk trade.

I like trading the OEX.  I get good fills, often better than theoretical prices.  It has good liquidity with 100’s to 1000’s of contracts of open interest.  It requires 1/10th as many contracts as SPY (hence 1/10th the commission, sorry Tom Sosnoff).

Here’s the trade:

First I put on an Aug / Sep $425 / $470 put diagonal.  (+10 Sep $470 puts / –10 Aug $425 puts).  This gets me long Vega and short Delta with a small positive Theta.  It has limited losses to the upside but is sensitive to a drop in IV.  It looks like this: (Click any picture to enlarge)

Next, I put on an Aug / Sep $475 / $480 ratio call reverse diagonal. (+10 Aug $475 calls / –5 Sep $480 calls).  This gets me long delta and long Vega and is short Theta.  Being long vega is a double edge sword here.  If the market moves in the desired direction, down, the long Vega will make this hedge lose less, but it also makes it a less hedge than it first appears.  However, it is very long delta so that lessens the long Vega losses on the upside.  On the downside it has limited losses and becomes more of a long vega play than long delta. This part of the trade looks like this:

The combined trade looks like this:

I like to use diagonal spreads more than calendars.  I often find that I’ll put on an OTM put calendar and I’m correct and the underlying moves down very quickly.  When a calendar moves too quickly you don’t make anywhere near maximum profit.  For a calendar to make (near) max profit the underlying needs to be at the short strike at expiration week, not right away.  With the diagonal spread there isn’t that change in delta after you cross past the short strike price. 

I also like the above ‘ratio call reverse diagonal’.  It’s positive delta outweighs the long vega on the way up and as time goes on, it becomes less long vega and if the underlying moves down the long vega offsets some of the short delta. 

Exit strategy: Obviously I would not hold this trade past the Aug expiration despite owning Sep options.  I’ll look to take profit or small losses if the underlying moves up quickly.  I’ll also take small losses if it stays in a tight range and suffer from the short theta.  If if moves down past $450, I’ll start taking off one or a few contracts at at time to lock in some profit but I will not be in a rush to do so b/c I’ll be long theta at that time and presumably benefitting from my long vega.

Have a nice Independence day, and hopefully enjoy your long holiday theta!
