Long BAC, short XLF, name against its own sector: $1 of BAC against $1.50 of XLF, sized so that a typical day moves each leg by about the same amount. The spread is -19.6% over the last 120 sessions, -8.3% over the last 20, and today's level sits at the 5th percentile of its own path, deeply compressed, narrowing over the last ten sessions. Alpha 47 against 79, a gap of -32 points (-43 ten sessions ago). Net market exposure at this sizing: −0.19, a clean relative bet.
Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.
The spread is further below its one-year average than at any point in the last year, so there is no earlier stretch like today's to count.
One line of your account split $1 : $1.50 across the legs at the last close (BAC $50.87, XLF $58.41); fractions included. Arithmetic on a setting you choose, not a recommendation.

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 BAC and $1.50 short XLF 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 BAC and XLF carry each leg on its own.
