How AMPRIUS TECHNOLOGIES INC looks technically
AMPRIUS TECHNOLOGIES INC (AMPX) is trading 42.9% 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 52 trading days ago — a "death cross", a bearish long-term signal. A trend is forming but not yet strong — ADX, a 0–100 trend-strength gauge, is 21 (a reading of 25+ marks a strong trend). Momentum is beaten down — its 14-day RSI (a 0–100 momentum gauge) is 27, in oversold territory (below 30). MACD, a trend-momentum gauge, turned bearish about 7 trading days ago (its momentum flipped negative). It just made a new 20-day low, breaking below its recent trading range. It is 4.4% above its 52-week low (its lowest price of the past year).
Trend

| Distance from the 200-day | it is trading 42.9% below its 200-day average, the long-term trend line — a long-term downtrend | -42.9% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $9.75 | $9.75 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $13.28 | $13.28 |
| Swing structure | its recent peaks and dips disagree — one of them is rising while the other is not, so there is no clean up or down pattern in the swings | mixed — one of the two is not confirming |
| Last swing turn | its last significant turn was a swing high 22 calendar days ago — the swings before that are what the structure reading is measured on | 22 sessions |
| Since the 50/200 cross | its 50-day average crossed below its 200-day average about 52 trading days ago — a "death cross", a bearish long-term signal | 52 sessions |
| Trend strength (14-day ADX) | a trend is forming but not yet strong — ADX, a 0–100 trend-strength gauge, is 21 (a reading of 25+ marks a strong trend) | 21.0 |
Momentum
3
| 14-day RSI | momentum is beaten down — its 14-day RSI (a 0–100 momentum gauge) is 27, in oversold territory (below 30) | 27.4 |
|---|---|---|
| Position in its 14-day range | it is trading near the bottom of its 14-day range ($7.26 to $9.99) — its "stochastic" reading is 12 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. | 11.7 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bearish about 7 trading days ago (its momentum flipped negative) | 7 sessions |
Range
12
| 52-week high | its highest closing price over the past year (about 252 trading days) was $24.23 | $24.23 |
|---|---|---|
| From the 52-week high | it is 68.7% below its 52-week high (its highest price of the past year) | -68.7% |
| Above the 52-week low | it is 4.4% above its 52-week low (its lowest price of the past year) | +4.4% |
| Below the 52-week high | it is 68.7% below its highest point of the past year | 68.7% |
| Since a 20-day breakout | it just made a new 20-day low, breaking below its recent trading range | 1 session |
| Since a 55-day breakout | it just made a new 55-day low, breaking below its recent trading range | 1 session |
| All-time high | its highest closing price on record is $24.23 (set on 2026-06-02) | $24.23 |
| Given back of the 52-week move | over the past year its closes ranged ($7.58 to $22.91), and it has recovered essentially none of its fall from last year’s high — 0% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $17.05 to $17.54. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 0.0% |
| From the all-time high | it is 68.7% below its all-time high | -68.7% |
| Nearest price level | it is trading 23.0% below a resistance level at $9.32 — a price it turned at three times since 2025-11-21, most recently on 2026-09-02. Since 2024-10-21 it has 4 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. | +23.0% |
| All-time low | its lowest closing price on record is $0.6132 (set on 2024-09-09) | $0.6132 |
| Above the all-time low | it is 1136.1% above its all-time low | +1,136% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are narrower than usual versus its own recent 6-month history (tighter than about 73% of it) | 27th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $0.6041 between its high and its low — about 8.0% 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 | $0.6041 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $7.53 and $10.57 — 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 | $7.53 – $9.05 – $10.57 |
| Typical daily range (% of price) | its price moves about 8.0% 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 | 8.0% |
| Stretch from the 200-day average | it is trading 9.4 daily ranges below its 200-day average price (42.9% 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 | 9.4 daily ranges below its 200-day average |

Candlestick patterns

| Since a doji | 9 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 | 9 sessions ago |
|---|---|---|
| Since a hammer | 9 sessions ago, after a stretch of decline, it sold off hard during the session and then closed back near its high — a "hammer", the long lower wick showing the drop was bought back before the close | 9 sessions ago |
| Since a bullish engulfing | 3 sessions ago it opened below the previous session's close and finished above that session's open — a "bullish engulfing" pair, where one up day more than undid the down day before it | 3 sessions ago |
Price gaps
3
| Gap at the open | it opened on 2026-10-20 2.4% 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 | -2.4% |
|---|---|---|
| Open gap | it gapped 2.2% below the previous close 4 sessions ago and has not traded back through the level it left behind at 8.56 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | -2.2% |
| Gap filled | a 2.4% gap down opened on 2026-10-20 has been "filled" today — price traded back through the level the gap left behind, and it closed again during the very session that opened it | today |
Price streaks
1
| Closing streak | it has closed lower 3 sessions in a row, a -9.76% move over the run — an unbroken run of down days, which describes what has already happened and says nothing about the next session | 3 sessions down |

Signal agreement
2
| Bullish technical signals | 2 of the 9 technical signals we can compute for it are currently in a bullish state: its RSI momentum gauge is oversold (a beaten-down reading), 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: a "death cross" — its 50-day average is below its 200-day, trading below its 200-day average, a fresh 20-day low, MACD momentum is negative, 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 27% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-09-14 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 13.5% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | -27.3% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 46% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $13.99 — a volume-weighted average of daily closes over 198 sessions, not a true tick-by-tick VWAP. | -45.8% |
|---|---|---|
| Vs the average paid since it last reported | the price is 24% below the average price paid since it last reported on 2026-08-04 (its 8-K), so the typical buyer over that stretch is under water. That average is $10.00 — a volume-weighted average of daily closes over 55 sessions, not a true tick-by-tick VWAP. | -24.2% |
Price levels it has turned at before
AMPX last closed at $7.58 on 2026-10-20. Since 2024-10-21 it has turned at 4 prices below its last close and 4 above; the 3 nearest below and the 3 nearest above are listed, nearest first.
| Level | Side | Distance | Evidence |
|---|---|---|---|

| $2.92 | Support | 61.5% below the last close | turned there twice · 2025-02-03 to 2025-05-13 |

| $14.16 | Resistance | 86.8% above the last close | turned there twice · 2025-10-07 to 2026-05-20 |
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
No Elliott-wave labelling currently fits its swings: the recent highs and lows do not satisfy the three rules a five-wave count has to obey, so there is no count to show rather than a count we are unsure about.
Read from daily closes as of 2026-10-20.

Management's Discussion & Analysis (MD&A)
- Notes:
- The newer MD&A text ends mid-sentence at 'Part I,' and is truncated, so full comparison of the complete sections is not possible from the provided excerpts.
- The provided excerpts of both filings appear identical in the text shown.
Risk Factors
- Added:
- In the newer filing (filed 2026-08-06), the 'Highly Competitive Market' section includes the parenthetical expansion '(“LEV”)' after the first mention of 'light electric vehicle'.
- Removed:
- In the older filing (filed 2026-05-07), the 'Establishing Manufacturing Capacity' section included a paragraph about the Brighton, Colorado lease: 'In April 2023, we entered into a lease agreement to lease approximately 774,000 square feet of premises in Brighton, Colorado. On January 30, 2026, we entered into an agreement with the lessor to terminate this lease in exchange for a one-time payment of $20.0 million. The termination of the lease was reflected in our results of operations as discussed above. We believe that our contract manufacturing strategy enables rapid capacity expansion with minimal capital investment.' This paragraph is not present in the newer filing (filed 2026-08-06).
- Reworded:
- The date reference in the 'Establishing Global Network of Contract Manufacturing Partnerships' section changed from 'As of March 31, 2026' (older filing, filed 2026-05-07) to 'As of June 30, 2026' (newer filing, filed 2026-08-06), appearing in two places within that section.
- The date reference in the 'Establishing Manufacturing Capacity' section changed from 'As of March 31, 2026' (older filing, filed 2026-05-07) to 'As of June 30, 2026' (newer filing, filed 2026-08-06).
- Notes:
- The newer filing text is truncated at the end of the 'Global Risks' section ('our batteries are incorporated into end pr'), so changes after that point cannot be fully assessed.
- The newer filing text includes a page break artifact ('21 Table of Contents') not present in the older filing excerpt; this appears to be a formatting artifact rather than a substantive change.

Only open-market purchases (SEC code P) and sales (code S) are counted here. Option exercises, vesting/awards, gifts, and shares withheld for taxes are excluded — they are compensation or mechanical, not open-market conviction. 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)

reported quarterly holdings change (2026-03-31 → 2026-06-30): 0 new, 5 increased, 0 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)
AMPX had 22,815,859 shares of reported short interest as of the 2026-09-30 FINRA settlement date (delayed, bi-monthly; not real-time).
AMPX had 15.6% of its shares outstanding sold short as of the 2026-09-30 FINRA settlement date (percent of FLOAT would be higher — float is not disclosed in the source). FINRA reported 3.8 days to cover at the same settlement.
- Reported short interest (shares) 22,815,859
- Short interest (% of shares outstanding) 15.6%
- Prior settlement (shares) 22,685,478
- Reported change 0.57%
- Days to cover (reported) 3.8
Reported to FINRA as of the 2026-09-30 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.
