but the question lies.. where does the out of sink future go in the fly.. typically in a single fly if say june is out of sink and trading at a premium.. you sell that as the meat and buy the wings
As you know, a fly is a spread between two spreads, (A-B) - (B-C), but the end result is that one is typically focusing on body vs wings or vice-versa.
A DF is really just (A-2B+C) - (B-2C+D) and could be considered a spread of flies, in the same way that a fly is a spread of spreads. If you look at it that way it's conceptually more of a spread than a fly. However, another way of looking at it is that a DF is also AB-2*BC+CD meaning that the body is the BC spread and the wings are the AB and CD spreads. You're not focusing on an out of sync future you're focusing on an out of sync
spread. I'd imagine that for the more sophisticated STIRs guys that are trading these regularly they're doing them for all sorts of reasons and not necessarily isolating something specifically.
Remember the stuff
@Wingz was talking about? If you have a 6m spread there are 6x1m spreads, 3x2m spreads, 2x3m spreads, etc. that when adjacently summed together they result in the original spread. These are all the combinations out of a 6m spread:
Code:
o: M N Q U V X Z
1: MN NQ QU UV VX XZ
2: MQ NU QV UX VZ
3: MU NV QX UZ
4: MV NX QZ
5: MX NZ
6: MZ
e.g. using a 6m spread and 2m adjacent components summed:
Code:
CLM7:CLQ7 + CLQ7:CLV7 + CLV7:CLZ7 (Q and V cancel out)
=> CLM7:CLZ7
But rather than spreading all the component spreads against the 6m spread (which would be kinda pointless) it's instead possible to hone in on a more specific spread that is perceived as out of line. In the above there is an obvious center, CLQ7:CLV7, and if you combine 3 of those 2m spreads
against the same 6m CLM7:CLZ7 spread it's part of you get:
Code:
CLM7:CLZ7 - 3*CLQ7:CLV7
=> CLM7 - 3*CLQ7 + 3*CLV7 - CLZ7 (DF)
=> CLM7:CLQ7 - 2*CLQ7:CLV7 + CLV7:CLZ7 (DF)
Which is a double fly with QV as the body and MQ and VZ as the wings.
