The airline sector pulled back across the board this scan. Every one of the six tracked names posted a negative weekly change and a lower RSI than last scan, and three — Southwest ($LUV), American ($AAL), and Alaska ($ALK) — broke back down from strong-up to weak-down trend, extending a pattern that has repeatedly flipped this cluster between the two states. Delta ($DAL), United ($UAL), and the sector-tracking ETF ($JETS) held their strong-up trend but weakened materially, with RSI easing into the low 50s. Alaska posted the sector's worst weekly decline (-8.01%) and its 52-week-high gap widened further to -27.90%, still the group's widest by a large margin.

Delta, United, and the sector-tracking ETF held their strong-up trend classification but weakened across every other measure this scan. Delta's RSI eased from 58.4 to 52.3 while its weekly change reversed from +4.46% to -2.18%; its 30-day change decelerated slightly to +3.94% (was +4.89%) and its 52-week-high gap widened to -4.57% (was -2.65%). United's RSI dropped from 58.4 to 52.1, its weekly print reversed from +6.78% to -3.26%, and its 52-week-high gap widened to -8.95% (was -4.33%) even as its 30-day change ticked up slightly to +3.61%. JETS followed the same shape: RSI down from 56.4 to 50.2, weekly change reversed from +4.03% to -3.01%, and its 52-week-high gap — the sector's tightest last scan at -1.56% — widened to -6.46%.

The more notable move is structural: Southwest, American, and Alaska all broke back down from strong-up to weak-down trend this scan. Southwest's RSI dropped from 49.7 to 41.3 and its weekly change reversed from +4.63% to -5.93%, with its 30-day change worsening to -10.13% (was -3.31%) — another swing in the back-and-forth pattern this pair has shown across recent scans; last scan's move to strong-up was already the fourth such flip. American's RSI fell from 52.3 to 44.0, its weekly print reversed to -6.96% (was +4.39%), and its 30-day change worsened to -5.12% (was -3.51%). Alaska, which had held strong-up through the last several scans and posted the sector's best 30-day gain (+5.11%) as recently as last scan, broke down alongside them this scan: RSI down from 54.8 to 44.2, weekly change the sector's worst at -8.01% (was +5.29%), and 30-day change swinging back negative to -4.01% (was +5.11%). Alaska's 52-week-high gap, already the sector's widest last scan at -20.99%, widened further to -27.90%.

RSI (Relative Strength Index) gauges how aggressively a stock has been bought or sold over roughly the past two weeks, on a 0-100 scale — under 30 signals an oversold, potentially undervalued stretch; over 70 signals overbought, extended risk; readings in between are neutral. The color icons below track that scale: green marks a healthy/strong reading, yellow marks neutral or mixed signals, orange marks an extended-but-not-extreme reading, red marks a breakdown or the sector's worst reading. Trend reflects a stock's structural direction based on its moving averages (strong-up, weak-up, weak-down, strong-down); vs SMA20 shows how far price sits above or below its 20-day average; 52wkHi shows the distance below the stock's own one-year high — the closer to zero, the closer to a new high.

RSI < 25 (Oversold): None this scan.

RSI 25-40 (Approaching Oversold): None this scan.

RSI 40+ (Neutral-to-Strong) — the whole sector: All six names sit in this band, split into two groups. Delta (52.3), United (52.1), and JETS (50.2) held their strong-up trend but eased into the low 50s after sitting in the upper 50s last scan. Southwest (41.3), American (44.0), and Alaska (44.2) all broke back down to weak-down trend this scan — Alaska's break is the more notable one, since it had held strong-up and posted the sector's best 30-day gain as recently as last scan, and its 52-week-high gap remains by far the sector's widest at -27.90%.

Does this scan's pullback stabilize, or does the sector keep deteriorating next scan? Does Southwest and American's re-break persist, or does the back-and-forth flip pattern reverse again the way it has repeatedly? And is Alaska's break to weak-down a one-scan wobble or the start of a durable trend change, given it had been one of the sector's steadiest strong-up names?
