Valuation 68th (price to earnings 20.9, price to book 2.3) and financial health 54th (debt to equity 0.5); weakest is capital return (31st, net share count bought back over the year -7.3, consecutive years of dividend increases 3 years).
Scores as of 8 Oct 2026. Each bar is a percentile: how this company ranked against every company the score ranked, 0–100. A list is a published formula and its output, not a recommendation. Method version 4.
Dividend coverage
Not assessed — last reported dividend predates the accounts. The most recent fiscal year in which AIR reported a dividend payment is FY2021, while its reported financial statements run through FY2026. Coverage is therefore not assessed for the latest year — an FY2021 ratio would not describe AIR today.
Coverage is derived from reported SEC EDGAR XBRL figures, comparing dividends paid against net income and free cash flow for the SAME fiscal year. It is not shown here because the latest fiscal year with a reported dividend payment (FY2021) is older than the latest year of reported financial statements (FY2026), so any ratio would describe an out-of-date year. Informational only — not financial advice.
How AAR CORP looks technically
AAR CORP (AIR) is trading 13.3% below its 200-day average, the long-term trend line — a long-term downtrend. Its 50-day average crossed above its 200-day average about 313 trading days ago — a "golden cross", a bullish long-term signal. A strong downtrend is in place — ADX, a 0–100 trend-strength gauge, is 29, with sellers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 33, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 8 trading days ago (its momentum flipped negative). It made a new 20-day low about 2 trading days ago. It is 34.0% below its highest point of the past year.
Trend
8
| Distance from the 200-day | it is trading 13.3% below its 200-day average, the long-term trend line — a long-term downtrend | -13.3% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $127.13 | $127.13 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $117.12 | $117.12 |
| Swing structure | each recent peak has been lower than the one before it and each dip deeper — the pattern chart-watchers call a downtrend, which describes where price has already been and not where it goes next | lower highs and lower lows |
| Last swing turn | its last significant turn was a swing high 13 calendar days ago — the swings before that are what the structure reading is measured on | 13 sessions |
| Wave structure | its recent swings can be read as a five-part downward sequence — what Elliott-wave chartists call an impulse — now in leg 3 of five; the labelling fails if price closes above 122. It is one of several labellings that fit, and it describes the swings already printed, not what comes next. The same swings also read as a three-part correction in leg C. | possible downward five-wave sequence, in wave 3 (one of several readings) |
| Since the 50/200 cross | its 50-day average crossed above its 200-day average about 313 trading days ago — a "golden cross", a bullish long-term signal | 313 sessions |
| Trend strength (14-day ADX) | a strong downtrend is in place — ADX, a 0–100 trend-strength gauge, is 29, with sellers in control | 29.2 |
Momentum

| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 33, neither overbought (above 70) nor oversold (below 30) | 33.4 |
|---|---|---|
| Position in its 14-day range | it is trading near the bottom of its 14-day range ($98.00 to $122.00) — its "stochastic" reading is 15 out of 100, where 0 would mean closing exactly at the 14-session low and 100 exactly at the high. This measures WHERE the price sits inside its recent range, which is a different question from the RSI beside it: RSI is a momentum gauge, measuring how FAST the price has been moving, so a stock can drift quietly to the bottom of its range with an ordinary RSI, or fall sharply and still sit in the middle. It has been climbing within that range over the last few sessions. | 14.9 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bearish about 8 trading days ago (its momentum flipped negative) | 8 sessions |
Range

| All-time high | its highest closing price on record is $153.86 (set on 2026-08-06) | $153.86 |
| Given back of the 52-week move | over the past year its closes ranged ($77.35 to $153.71), and it has given back well over two thirds of its rise from last year’s low — 68% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $104.08 to $106.52. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 68.3% |
| From the all-time high | it is 34.0% below its all-time high | -34.0% |
| Nearest price level | it is trading 2.1% above a support level at $99.40 — a price it turned at twice since 2026-03-13, most recently on 2026-05-19. Since 2024-10-08 it has 11 such levels below the current price and 4 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | -2.1% |
| All-time low | its lowest closing price on record is $8.56 (set on 2020-03-19) | $8.56 |
| Above the all-time low | it is 1086.7% above its all-time low | +1,087% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are unusually wide versus its own recent history (wider than about 87% of the past ~6 months) | 87th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $5.34 between its high and its low — about 5.3% of its price. That is its "average true range" over the last 14 sessions, which also counts the distance from the previous close, so a day that opens well away from yesterday counts as the large move it was | $5.34 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $95.32 and $127.37 — the "Bollinger bands", a range drawn two standard deviations either side of its 20-day average price, which widens when the stock gets more volatile and narrows when it settles | $95.32 – $111.35 – $127.37 |
| Typical daily range (% of price) | its price moves about 5.3% in a typical session — about typical for the companies we cover. This is the average gap between a session's high and low over the last 14 sessions, counting overnight moves, expressed against the current price so it can be compared with companies trading at any price | 5.3% |
| Stretch from the 200-day average | it is trading 2.9 daily ranges below its 200-day average price (13.3% below it in plain percentage terms) — a way of asking how far it has stretched from its own average in units of how far it normally moves in a day, so a calm company and a jumpy one can be compared on the same scale | 2.9 daily ranges below its 200-day average |

Candlestick patterns

| Since a doji | 3 sessions ago it opened and closed at almost the same price after trading through a wider range — a "doji", the classic picture of buyers and sellers finishing the session level | 3 sessions ago |
|---|---|---|
| Since a bearish engulfing | 7 sessions ago it opened above the previous session's close and finished below that session's open — a "bearish engulfing" pair, where one down day more than undid the up day before it | 7 sessions ago |
Price gaps
3
| Gap at the open | it opened on 2026-10-08 0.6% below the previous session's close — an overnight gap, the part of the move that happened while the market was shut, and traded back through that level before the close | -0.6% |
|---|---|---|
| Open gap | it gapped 2.4% below the previous close 18 sessions ago and has not traded back through the level it left behind at 125.48 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | -2.4% |
| Gap filled | a 2.1% gap up opened on 2026-09-17 has been "filled" 15 sessions ago — price traded back through the level the gap left behind, and it closed again during the very session that opened it | 15 sessions ago |

Signal agreement
2
| Bullish technical signals | 2 of the 9 technical signals we can compute for it are currently in a bullish state: a "golden cross" — its 50-day average is above its 200-day, near the bottom of its 14-day range (oversold) — these describe past price behaviour, not a forecast | 2 of 9 |
|---|---|---|
| Bearish technical signals | 6 of the 9 technical signals we can compute for it are currently in a bearish state: trading below its 200-day average, a fresh 20-day low, MACD momentum is negative, a strong downtrend, with sellers in control, lagging the market over 6 months, trading below the Ichimoku cloud — these describe past price behaviour, not a forecast | 6 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 25% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-09-01 and projected forward over today's price, the side traders read as an established downtrend, with the band above acting as the level that would have to be cleared. The band itself is moderate, spanning 3.5% of the share price. | -24.9% |
|---|
Volume-weighted price
1
| Vs this year’s average price paid | the price is 13% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $116.42 — a volume-weighted average of daily closes over 190 sessions, not a true tick-by-tick VWAP. | -12.8% |

A level is a price this company reversed or paused at more than once — they describe past behaviour, not a forecast of where the price will go.
Wave structure
Its recent swings can be read as a five-part downward sequence — what Elliott-wave chartists call an impulse — now in leg 3 of five.
This labelling fails — stops being a possible reading at all — if it closes above $122.00.
This is one of several labellings that fit the same swings, so treat it as a reading rather than the reading. It was chosen from 2 labellings that survived the rules, counting shorter readings of the same bars.
On past moves of this shape the leg has usually ended somewhere between $51.62 and $78.50 — that is where it has tended to end if the count holds, not a forecast of where the price goes.
Alternate reading: The same swings also read as a three-part correction in leg C, which fails on a close above $122.00.
This reading has stood for 5 trading days, since 2026-10-02.
Read from daily closes as of 2026-10-08.
An Elliott-wave count describes the swings already printed and the level that would disprove it. It is not a forecast, a target, or advice.

Sales may be planned and non-discretionary (e.g. a Rule 10b5-1 plan) and are not necessarily bearish; open-market buying is not a recommendation to buy. Informational only — not financial advice.
Institutional ownership (13F)
5 institutional 13F filers reported holding AIR as of 2026-06-30 (quarter-end position, filed within 45 days).
- Distinct 13F filers 5
- Reported shares held 9,747,645
- Reported value $1,393,216,263
reported quarterly holdings change (2026-03-31 → 2026-06-30): 1 new, 3 increased, 1 decreased, 0 exited. Change counts cover only managers that filed 13F reports in BOTH quarters, derived between two quarter-end snapshots — not same-day trades; a single manager is never said to have "bought" or "sold".
Institutional holdings are quarter-end long positions reported on SEC Form 13F-HR, filed up to 45 days after the quarter ends — they are delayed, are not real-time trades, exclude short positions and most non-US securities, and are not investment advice. Any increase/decrease is a reported change between two quarterly snapshots, not a same-day purchase or sale. These are quarter-end snapshots from the 13F filings on SEC EDGAR, filed within 45 days — not real-time, and any change is a difference between two quarterly reports, not a same-day trade.

Short interest (FINRA)
AIR had 1,599,093 shares of reported short interest as of the 2026-09-15 FINRA settlement date (delayed, bi-monthly; not real-time).
AIR had 3.98% of its shares outstanding sold short as of the 2026-09-15 FINRA settlement date (percent of FLOAT would be higher — float is not disclosed in the source). FINRA reported 4.7 days to cover at the same settlement.
- Reported short interest (shares) 1,599,093
- Short interest (% of shares outstanding) 3.98%
- Prior settlement (shares) 1,488,188
- Reported change 7.45%
- Days to cover (reported) 4.7
Reported to FINRA as of the 2026-09-15 settlement date. Short interest is reported to FINRA and published on a delayed, bi-monthly schedule (as of a settlement date, disseminated roughly eight business days later) — it is NOT real-time, does not cover every venue or all US trading, and is not a short-squeeze prediction or investment advice. Days-to-cover is the value FINRA reports; percent of float is not shown because the source file carries no share-count denominator — where a percent appears it is of shares OUTSTANDING, the larger base, and is therefore a floor on percent of float.
