BlueHoreshoe,
For the 2/5/30 yr fly you are essentially looking at it as two separate yield curve trades. The 2/5 or TUF spread weighting is normally 100:90 and the 5/30 or FOB spread weighting is almost always 250:100. Thus, if you are looking to do this spread the optimum ratio would be 100:340:100 or at its smallest unit 5:17:5. The futures spread is kind of a proxy for a cash belly vs. wings play.
Thanks. I might have a go at charting this over the last few years. Meanwhile, TUT just inverted again so we are looking for another entry.
Then again, if one expects an equities sell-off around Sep-Oct seasonal low, TUT could hit a multi-year low about then as well. Might want to keep the powder dry for a monster position then.
Hmm ...
