Delta Air Lines against Boeingsame sector · as of the Nov 13 close · tape Flat

Long DAL, short BA, same sector: $1 of DAL against $1.00 of BA, sized so that a typical day moves each leg by about the same amount. The spread is +30.4% over the last 120 sessions, +22.1% over the last 20, and today's level sits at the 94th percentile of its own path, very stretched, widening over the last ten sessions. Alpha 57 against 20, a gap of +37 points (+14 ten sessions ago). Net market exposure at this sizing: +0.50, it leans long the market. Same sector, not true peers on the desk's test.

Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.

The spread is further above its one-year average than at any point in the last year, so there is no earlier stretch like today's to count. No hand-off in view: neither leg is where a cycle pair starts.

The house book in this pair

Each leg against its sector fund, and each leg's true peers.

How to read it: the spread is what $1 long DAL and $1.00 short BA would have made together, in percent of the long leg, close to close, before costs; the market's move cancels in it to the extent the two legs share it. Stretch is where today's level sits among the last 120 sessions of that path, a description of the spread's own history and not a forecast. Net β is the pair's remaining market exposure per $1 long at this sizing (each leg's beta over 250 sessions). The pages for DAL and BA carry each leg on its own.
