Long XLF, short MS, name against a sector: $1 of XLF against $0.50 of MS, sized so that a typical day moves each leg by about the same amount. The spread is +15.6% over the last 120 sessions, +2.5% 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 72 against 49, a gap of +23 points (+12 ten sessions ago). Net market exposure at this sizing: +0.04, a clean relative bet.
Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.
The last 4 times these two sat this far above their one-year average, 1 closed half the gap within ten sessions: a spread that has tended to keep going.

The house book has not closed a trade in this pair.
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 XLF and $0.50 short MS 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 XLF and MS carry each leg on its own.
