Ciena against Seagatesame sector · as of the Nov 13 close · tape Flat

Long CIEN, short STX, same sector: $1 of CIEN against $1.07 of STX, sized so that a typical day moves each leg by about the same amount. The spread is -18.3% over the last 120 sessions, +4.5% over the last 20, and today's level sits at the 92nd percentile of its own path, very stretched, widening over the last ten sessions. Alpha 44 against 27, a gap of +17 points (+9 ten sessions ago). Net market exposure at this sizing: +0.16, a clean relative bet. Same sector, not true peers on the desk's test.

Not on the desk's list as of Nov 10, three sessions behind. Pro sees today's list.

The spread sits near the middle of its range, so there is no stretch to count today. No hand-off in view: neither leg is where a cycle pair starts.

The house book in this pair

The house book has not closed a trade in this pair.

Each leg against its sector fund, and each leg's true peers.

How to read it: the spread is what $1 long CIEN and $1.07 short STX 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 CIEN and STX carry each leg on its own.
