Long LUV, short XLI, name against its own sector: $1 of LUV against $2.07 of XLI, sized so that a typical day moves each leg by about the same amount. The spread is +9.3% over the last 120 sessions, +11.5% over the last 20, and today's level sits at the 95th percentile of its own path, very stretched, widening over the last ten sessions. Alpha 75 against 59, a gap of +16 points (+22 ten sessions ago). Net market exposure at this sizing: −0.64, it leans short the market.
Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.

The house takes every listed cycle pair by the rules, after average trading costs; its full record is on the engine page. Pairs you assemble yourself are ideas, not posted trades: the Hedge pairs chapter says how the two differ.
How to read it: the spread is what $1 long LUV and $2.07 short XLI 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 LUV and XLI carry each leg on its own.
