How PERMA FIX ENVIRONMENTAL SERVICES I looks technically
PERMA FIX ENVIRONMENTAL SERVICES I (PESI) is trading 29.9% above its 200-day average, the long-term trend line — a longer-term uptrend. Its 50-day average crossed above its 200-day average about 13 trading days ago — a "golden cross", a bullish long-term signal. A strong uptrend is in place — ADX, a 0–100 trend-strength gauge, is 42, with buyers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 54, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 7 trading days ago (its momentum flipped negative). It made a new 20-day high about 8 trading days ago. It is 18.9% below its highest point of the past year. Trading volume is unusually light — only about 40% of its 30-day average.
Trend
9
| Distance from the 200-day | it is trading 29.9% above its 200-day average, the long-term trend line — a longer-term uptrend | +29.9% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $15.05 | $15.05 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $13.32 | $13.32 |
| Swing structure | each recent peak has been higher than the one before it and each dip has been shallower — the pattern chart-watchers call an uptrend, which describes where price has already been and not where it goes next | higher highs and higher lows |
| Last swing turn | its last significant turn was a swing high 9 calendar days ago — the swings before that are what the structure reading is measured on | 9 sessions |
| Wave structure | its recent swings can be read as a completed five-part upward sequence — the pattern Elliott-wave chartists call an impulse — which on that reading would now be due a pullback rather than more of the same; the labelling fails if price closes above 21.3199. It is the only labelling that fits, though not with textbook proportions, and it describes the swings already printed, not what comes next. | possible five-wave upward sequence, complete (atypical proportions) |
| Since the 50/200 cross | its 50-day average crossed above its 200-day average about 13 trading days ago — a "golden cross", a bullish long-term signal | 13 sessions |
| Above the 200-day after a dip | it recently dipped to its 200-day average (the long-term trend line) and has since climbed back above it — now about 29.9% above | +29.9% |
| Trend strength (14-day ADX) | a strong uptrend is in place — ADX, a 0–100 trend-strength gauge, is 42, with buyers in control | 42.1 |
Momentum
3
| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 54, neither overbought (above 70) nor oversold (below 30) | 54.3 |
|---|---|---|
| Position in its 14-day range | it is trading near the bottom of its 14-day range ($16.51 to $21.32) — its "stochastic" reading is 16 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. | 16.4 |
| 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 $21.32 | $21.32 |
|---|---|---|
| From the 52-week high | it is 18.9% below its 52-week high (its highest price of the past year) | -18.9% |
| Above the 52-week low | it is 115.7% above its 52-week low (its lowest price of the past year) | +115.7% |
| Below the 52-week high | it is 18.9% below its highest point of the past year | 18.9% |
| Since a 20-day breakout | it made a new 20-day high about 8 trading days ago | 8 sessions |
| Since a 55-day breakout | it made a new 55-day high about 8 trading days ago | 8 sessions |
| All-time high | its highest closing price on record is $21.32 (set on 2026-08-12) | $21.32 |
| Given back of the 52-week move | over the past year its closes ranged ($8.19 to $19.43), and it has given back roughly a quarter of its rise from last year’s low — 19% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $12.12 to $12.48. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 18.9% |
| From the all-time high | it is 18.9% below its all-time high | -18.9% |
| Nearest price level | it is trading 6.1% above a support level at $16.25 — a price it turned at four times since 2024-11-01, most recently on 2026-07-01. Since 2024-08-21 it has 14 such levels below the current price and 0 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | -6.1% |
| All-time low | its lowest closing price on record is $1.80 (set on 2013-06-28) | $1.80 |
| Above the all-time low | it is 861.1% above its all-time low | +861.1% |
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 87% of it) | 13th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $1.23 between its high and its low — about 7.1% 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 | $1.23 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $15.71 and $18.91 — 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 | $15.71 – $17.31 – $18.91 |
| Typical daily range (% of price) | its price moves about 7.1% 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 | 7.1% |
| Stretch from the 200-day average | it is trading 3.2 daily ranges above its 200-day average price (29.9% above 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 | 3.2 daily ranges above its 200-day average |
Volume

| Volume vs its 30-day average | trading volume is unusually light — only about 40% of its 30-day average | 0.40× |

| Change in the average price target | analysts have raised their average price target by 20.0% since the prior reading | +20.0% |
|---|---|---|
| Change in the consensus rating | the analyst consensus rating is unchanged since the prior reading | unchanged |
Candlestick patterns
3
| Since a doji | 8 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 | 8 sessions ago |
|---|---|---|
| Since a hammer | today, 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 | today |
| Since a bearish engulfing | 6 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 | 6 sessions ago |
Price gaps
2
| Gap at the open | it opened on 2026-08-21 1.4% 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 | +1.4% |
|---|---|---|
| Gap filled | a 6.6% gap up opened on 2026-08-13 has been "filled" 6 sessions ago — price traded back through the level the gap left behind, and it closed again during the very session that opened it | 6 sessions ago |
Price streaks
1
| Closing streak | it closed higher in its latest session, after a session that did not close higher — a single up day rather than a run | 1 session up |
|---|
Relative strength
4
| vs market, 1 month | over the past 1 month this stock beat the market by 1.6 percentage points (the stock gained 4.0% while the market gained 2.3%) | +1.6% |
|---|---|---|
| vs market, 3 months | over the past 3 months this stock beat the market by 87.9 percentage points (the stock gained 90.9% while the market gained 3.1%) | +87.8% |
| vs market, 6 months | over the past 6 months this stock beat the market by 17.8 percentage points (the stock gained 28.9% while the market gained 11.1%) | +17.9% |

Signal agreement
2
| Bullish technical signals | 6 of the 9 technical signals we can compute for it are currently in a bullish state: a strong uptrend, with buyers in control, a "golden cross" — its 50-day average is above its 200-day, trading above its 200-day average, outperforming the market over 6 months, near the bottom of its 14-day range (oversold), trading above the Ichimoku cloud — these describe past price behaviour, not a forecast | 6 of 9 |
|---|---|---|
| Bearish technical signals | 1 of the 9 technical signals we can compute for it is currently in a bearish state: MACD momentum is negative — these describe past price behaviour, not a forecast | 1 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 22% above 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 uptrend, with the band below acting as the level that would have to give way. The band itself is thick, spanning 8.2% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | +22.4% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 23% above the average price paid so far this year, so the typical buyer over that stretch is showing a gain. That average is $14.10 — a volume-weighted average of daily closes over 158 sessions, not a true tick-by-tick VWAP. | +22.7% |
|---|---|---|
| Vs the average paid since it last reported | the price is 3% below the average price paid since it last reported on 2026-07-28 (its 8-K), so the typical buyer over that stretch is under water. That average is $17.78 — a volume-weighted average of daily closes over 19 sessions, not a true tick-by-tick VWAP. | -2.7% |
Price levels it has turned at before
PESI last closed at $17.30 on 2026-08-21. Since 2024-08-21 it has turned at 14 prices below its last close and 0 above; the 3 nearest below are listed, nearest first.
| Level | Side | Distance | Evidence |
|---|---|---|---|
| $16.25 | Support | 6.1% below the last close | turned there four times · 2024-11-01 to 2026-07-01 |
| $14.94 | Support | 13.7% below the last close | turned there three times · 2024-10-24 to 2026-01-13 |
| $14.66 | Support | 15.3% below the last close | turned there three times · 2025-12-09 to 2026-07-28 |
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 upward sequence — what Elliott-wave chartists call an impulse — now complete.
This labelling fails — stops being a possible reading at all — if it closes above $21.32.
It is the only labelling that fits these swings, though its proportions are not the textbook ones. It was chosen from 2 labellings that survived the rules, counting shorter readings of the same bars.
This reading has stood for 2 trading days, since 2026-08-20.
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.

Analyst EPS estimate for PESI
- Consensus EPS estimate-$0.11 next reporting period, as of 2026-08-23
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.
Key risks (from latest filing)
["Heavy reliance on government appropriations and procurement cycles, particularly from the U.S. Department of Energy.","Operational risks and regulatory uncertainty associated with the handling of hazardous and radioactive waste.","Potential for continued operating losses due to fixed costs and infrastructure investments while waiting for waste treatment volumes to scale."]

Insider activity (SEC Form 4)
No open-market insider purchases or sales are on record for PESI — recent Form 4 activity was compensation-related (awards, option exercises, or tax withholding), not open-market buying or selling.
View full insider trading history → View SEC Form 3/4/5 filingsOnly 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)
4 institutional 13F filers reported holding PESI as of 2026-03-31 (quarter-end position, filed within 45 days).

reported quarterly holdings change (2025-12-31 → 2026-03-31): 0 new, 2 increased, 2 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)
PESI had 2,100,130 shares of reported short interest as of the 2026-07-31 FINRA settlement date (delayed, bi-monthly; not real-time).
PESI had 9.90% 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 3.35 days to cover at the same settlement.
- Reported short interest (shares) 2,100,130
- Short interest (% of shares outstanding) 9.90%
- Prior settlement (shares) 2,315,207
- Reported change -9.29%
- Days to cover (reported) 3.35
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.
