Long RIVN, short XLY, name against its own sector: $1 of RIVN against $3.00 of XLY, sized so that a typical day moves each leg by about the same amount. The spread is -10.5% over the last 120 sessions, -17.0% over the last 20, and today's level sits at the 3rd percentile of its own path, deeply compressed, narrowing over the last ten sessions. Alpha 24 against 78, a gap of -54 points (-33 ten sessions ago). Net market exposure at this sizing: −1.73, it leans short the market.
Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.

How to read it: the spread is what $1 long RIVN and $3.00 short XLY 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 RIVN and XLY carry each leg on its own.
