How AMERICAN SUPERCONDUCTOR CORP looks technically
AMERICAN SUPERCONDUCTOR CORP (AMSC) is trading 18.2% below its 200-day average, the long-term trend line — a long-term downtrend. Its 50-day average crossed below its 200-day average about 8 trading days ago — a "death cross", a bearish long-term signal. A strong downtrend is in place — ADX, a 0–100 trend-strength gauge, is 36, with sellers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 39, neither overbought (above 70) nor oversold (below 30). It made a new 20-day low about 18 trading days ago. It is 57.4% below its highest point of the past year. Day-to-day price swings are unusually narrow versus its own recent history — a "Bollinger squeeze" (in the tightest 6% of the past ~6 months), which often precedes a bigger move.
Trend
8
| Distance from the 200-day | it is trading 18.2% below its 200-day average, the long-term trend line — a long-term downtrend | -18.2% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $35.04 | $35.04 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $36.67 | $36.67 |
| 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 14 calendar days ago — the swings before that are what the structure reading is measured on | 14 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 5 of five; the labelling fails if price closes above 34.24. It is the only labelling that fits, and it describes the swings already printed, not what comes next. | possible downward five-wave sequence, in wave 5 |
| Since the 50/200 cross | its 50-day average crossed below its 200-day average about 8 trading days ago — a "death cross", a bearish long-term signal | 8 sessions |

| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 39, neither overbought (above 70) nor oversold (below 30) | 39.4 |
|---|---|---|
| Position in its 14-day range | it is trading in the lower half of its 14-day range ($28.50 to $34.24) — its "stochastic" reading is 26 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 slipping within that range over the last few sessions. | 26.3 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, is in positive territory (momentum leaning bullish) | 15 sessions |
Range

| 52-week high | its highest closing price over the past year (about 252 trading days) was $70.49 | $70.49 |
|---|---|---|
| From the 52-week high | it is 57.4% below its 52-week high (its highest price of the past year) | -57.4% |
| Above the 52-week low | it is 20.7% above its 52-week low (its lowest price of the past year) | +20.7% |

| Since a 55-day breakout | it made a new 55-day low about 18 trading days ago | 18 sessions |
| All-time high | its highest closing price on record is $475.30 (set on 2008-06-24) | $475.30 |
| Given back of the 52-week move | over the past year its closes ranged ($25.95 to $66.68), and it has recovered only a small part of its fall from last year’s high — 10% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $51.12 to $52.42. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 10.0% |
| From the all-time high | it is 93.7% below its all-time high | -93.7% |
| Nearest price level | it is trading 0.5% below a resistance level at $30.17 — a price it turned at three times since 2025-01-06, most recently on 2026-01-21. Since 2024-08-21 it has 4 such levels below the current price and 8 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | +0.5% |
| All-time low | its lowest closing price on record is $2.89 (set on 2017-08-08) | $2.89 |
| Above the all-time low | it is 938.4% above its all-time low | +938.4% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are unusually narrow versus its own recent history — a "Bollinger squeeze" (in the tightest 6% of the past ~6 months), which often precedes a bigger move | 6th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $2.01 between its high and its low — about 6.7% 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 | $2.01 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $27.79 and $34.31 — 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 | $27.79 – $31.05 – $34.31 |
| Typical daily range (% of price) | its price moves about 6.7% in a typical session — more volatile than most 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 | 6.7% |
| Stretch from the 200-day average | it is trading 3.3 daily ranges below its 200-day average price (18.2% 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 | 3.3 daily ranges below its 200-day average |

Price gaps
3
| Gap at the open | it opened on 2026-08-21 1.5% above 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 | +1.5% |
|---|---|---|
| Open gap | it gapped 4.1% below the previous close 3 sessions ago and has not traded back through the level it left behind at 32.13 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | -4.1% |
| Gap filled | a 3.6% gap up opened on 2026-08-12 has been "filled" 6 sessions ago — price traded back through the level the gap left behind, and it took 1 session to close | 6 sessions ago |
Price streaks

Signal agreement
2
| Bullish technical signals | 1 of the 9 technical signals we can compute for it is currently in a bullish state: MACD momentum is positive — these describe past price behaviour, not a forecast | 1 of 9 |
|---|---|---|
| Bearish technical signals | 5 of the 9 technical signals we can compute for it are currently in a bearish state: a strong downtrend, with sellers in control, a "death cross" — its 50-day average is below its 200-day, trading below its 200-day average, lagging the market over 6 months, trading below the Ichimoku cloud — these describe past price behaviour, not a forecast | 5 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 21% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-07-16 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 thick, spanning 28.3% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | -20.5% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 22% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $38.34 — a volume-weighted average of daily closes over 157 sessions, not a true tick-by-tick VWAP. | -21.7% |
|---|---|---|
| Vs the average paid since it last reported | the price is 6% below the average price paid since it last reported on 2026-08-05 (its 10-Q), so the typical buyer over that stretch is under water. That average is $31.84 — a volume-weighted average of daily closes over 13 sessions, not a true tick-by-tick VWAP. | -5.7% |
Price levels it has turned at before
AMSC last closed at $30.01 on 2026-08-21. Since 2024-08-21 it has turned at 4 prices below its last close and 8 above; the 3 nearest below and the 3 nearest above are listed, nearest first.
| Level | Side | Distance | Evidence |

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 5 of five.
This labelling fails — stops being a possible reading at all — if it closes above $34.24.
It is the only labelling that fits these swings, though its proportions are not the textbook ones. It was chosen from 3 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 $4.50 and $22.88 — that is where it has tended to end if the count holds, not a forecast of where the price goes.
This reading has stood for 6 trading days, since 2026-08-14.
Read from daily closes as of 2026-08-21.
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.

Change over time is not available yet: it needs two readings of the same reporting period at least 30 days apart, and we have been recording these estimates since 2026-08-04. An estimate for a DIFFERENT quarter is not a revision, so a reading from before the last report is never compared with one after it.
The consensus estimate for the next reporting period, and how it has moved between readings of that SAME period. A change is measured only between readings estimating one period — when a company reports, the consensus moves to the next quarter and the two numbers are not comparable. Informational only, not a forecast and not advice.

Option exercises, vesting/awards, gifts, and shares withheld for taxes are excluded — they are compensation or mechanical, not open-market conviction.

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.

Short interest (FINRA)
AMSC had 3,532,626 shares of reported short interest as of the 2026-07-31 FINRA settlement date (delayed, bi-monthly; not real-time).
AMSC had 7.29% of its shares outstanding sold short as of the 2026-07-31 FINRA settlement date (percent of FLOAT would be higher — float is not disclosed in the source). FINRA reported 4.24 days to cover at the same settlement.
- Reported short interest (shares) 3,532,626
- Short interest (% of shares outstanding) 7.29%
- Prior settlement (shares) 3,403,538
- Reported change 3.79%
- Days to cover (reported) 4.24
Reported to FINRA as of the 2026-07-31 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.
