All six airline names carry a strong-up trend this scan. Southwest ($LUV) and American ($AAL) — the pair that has spent the last several scans oscillating between a broken and a recovered trend — flipped back to strong-up again this scan, the fourth such flip across this cluster's recent history. Delta ($DAL) and United ($UAL) both closed the week at an identical RSI of 58.4, the sector's strongest readings, and every name in the group narrowed its distance from a 52-week high. Alaska ($ALK) posted the sector's best 30-day gain (+5.11%) even though its 52-week-high gap (-20.99%) remains the widest, despite narrowing sharply from -27.98%.

The sector strengthened across the board this scan. Every one of the six names swung its 30-day change positive or materially less negative, and every 52-week-high gap narrowed — in some cases sharply. Delta and United led the firming: Delta's RSI held at 58.4 (up from 56.4) while its 30-day change swung from -5.18% to +4.89%, and United's RSI jumped from 51.2 to match Delta at 58.4, with the sector's best weekly print (+6.78%) and a 30-day change that flipped from -10.21% to +2.65%. Both names closed within single digits of a new 52-week high — Delta at -2.65%, United at -4.33%.

The more notable move is structural: Southwest and American, the two names whose trend has repeatedly broken down and recovered across this cluster's recent scans, both flipped back to strong-up this scan. Southwest's RSI climbed from 42.5 to 49.7 and its 30-day change improved from -10.9% to -3.31% — still negative, but the sharpest such improvement in the sector. American's RSI rose from 48.5 to 52.3, and its 30-day change improved from -15.87% (the sector's deepest decline last scan) to -3.51%, now roughly in line with Southwest rather than standing out as the sector's weakest name. JETS, the sector-tracking ETF, and Alaska both held their strong-up trend and firmed further: JETS' 52-week-high gap closed to -1.56%, the sector's tightest, while Alaska posted the sector's best 30-day print (+5.11%) even as its own 52-week-high gap, though narrowed to -20.99%, remains the widest in the group.

• Southwest: RSI 42.5→49.7 (recovered), trend re-broke weak-down→strong-up, fourth flip in this cluster's recent history, 7D -0.24%→+4.63% (turned positive), 30D -10.9%→-3.31% (improved sharply but still negative), 52wkHi -18.4%→-11.47% (narrowed).

• American: RSI 48.5→52.3 (recovered), trend re-broke weak-down→strong-up, fourth flip alongside Southwest, 7D +5.46%→+4.39% (roughly steady), 30D -15.87%→-3.51% (improved sharply, no longer the sector's deepest decline), 52wkHi -18.73%→-11.76% (narrowed).
• Alaska: RSI 51.0→54.8 (firmed), trend unchanged (strong-up), 7D +2.86%→+5.29% (accelerated), 30D -7.41%→+5.11% (swung positive, best in the sector this scan), 52wkHi -27.98%→-20.99% (narrowed but still the sector's widest gap).

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 oversold/healthy, yellow marks neutral, orange marks approaching overbought, red marks a breakdown or extreme overbought 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, and every one carries a strong-up trend. Delta and United are the firmest, both at RSI 58.4 and both within single digits of a new 52-week high. Southwest and American are the softest of the six, having just flipped back to strong-up for the fourth time in this cluster's recent history — their RSI readings (49.7 and 52.3) are the sector's lowest, and both still show a negative 30-day change even as the rest of the sector turned positive. JETS and Alaska sit in between: JETS closed the tightest 52-week-high gap in the sector (-1.56%), while Alaska posted the best 30-day gain (+5.11%) despite still carrying the sector's widest 52-week-high gap (-20.99%).

Does Southwest and American's fourth flip back to strong-up hold this time, or does the pattern repeat and one or both re-break next scan? Does Delta and United's matched RSI of 58.4 diverge as one extends further toward a new 52-week high? And does Alaska's 52-week-high gap keep narrowing from -20.99%, or does it stay the sector's laggard on that measure even with the best 30-day print in the group?
