Long NBIS, short XLK, name against its own sector: $1 of NBIS against $3.00 of XLK, sized so that a typical day moves each leg by about the same amount. The spread is -34.3% over the last 120 sessions, -12.8% over the last 20, and today's level sits at the 1st percentile of its own path, deeply compressed, narrowing over the last ten sessions. Alpha 21 against 22, a gap of -1 points (-1 ten sessions ago). Net market exposure at this sizing: −1.59, it leans short the market.
Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.
The spread is below its one-year average by more than at almost any point in the last year (1 earlier time), too few to count.
One line of your account split $1 : $3.00 across the legs at the last close (NBIS $125.40, XLK $174.58); fractions included. Arithmetic on a setting you choose, not a recommendation.

Each leg against its sector fund, and each leg's true peers.
How to read it: the spread is what $1 long NBIS and $3.00 short XLK 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 NBIS and XLK carry each leg on its own.
