How ENERGY RECOVERY INC looks technically
ENERGY RECOVERY INC (ERII) is trading 31.3% 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 115 trading days ago — a "death cross", a bearish long-term signal. There is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 15, below the 25 that marks a real trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 42, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 10 trading days ago (its momentum flipped negative). It made a new 20-day low about 9 trading days ago. It is 56.9% below its highest point of the past year.
Trend

| Distance from the 200-day | it is trading 31.3% below its 200-day average, the long-term trend line — a long-term downtrend | -31.3% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $8.53 | $8.53 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $11.50 | $11.50 |
| 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 low 8 calendar days ago — the swings before that are what the structure reading is measured on | 8 sessions |
| Since the 50/200 cross | its 50-day average crossed below its 200-day average about 115 trading days ago — a "death cross", a bearish long-term signal | 115 sessions |
| Trend strength (14-day ADX) | there is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 15, below the 25 that marks a real trend) | 15.0 |
Momentum
3
| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 42, neither overbought (above 70) nor oversold (below 30) | 42.3 |
|---|---|---|
| Position in its 14-day range | it is trading in the lower half of its 14-day range ($7.51 to $9.34) — its "stochastic" reading is 21 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. | 21.3 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bearish about 10 trading days ago (its momentum flipped negative) | 10 sessions |
Range
12
| 52-week high | its highest closing price over the past year (about 252 trading days) was $18.32 | $18.32 |
|---|---|---|
| From the 52-week high | it is 56.9% below its 52-week high (its highest price of the past year) | -56.9% |
| Above the 52-week low | it is 5.2% above its 52-week low (its lowest price of the past year) | +5.2% |

| Since a 55-day breakout | it made a new 55-day low about 9 trading days ago | 9 sessions |
| All-time high | its highest closing price on record is $30.76 (set on 2023-07-19) | $30.76 |
| Given back of the 52-week move | over the past year its closes ranged ($7.72 to $18.11), and it has recovered essentially none of its fall from last year’s high — 2% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $14.14 to $14.47. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 1.7% |
| From the all-time high | it is 74.3% below its all-time high | -74.3% |
| Nearest price level | it is trading 17.8% below a resistance level at $9.31 — a price it turned at three times since 2026-03-20, most recently on 2026-08-05. Since 2024-08-21 it has 0 such levels below the current price and 13 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | +17.8% |
| All-time low | its lowest closing price on record is $1.95 (set on 2012-04-12) | $1.95 |
| Above the all-time low | it is 305.1% above its all-time low | +305.1% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are about average versus its own recent 6-month history | 70th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $0.3595 between its high and its low — about 4.6% 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 | $0.3595 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $7.43 and $9.14 — 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 | $7.43 – $8.28 – $9.14 |
| Typical daily range (% of price) | its price moves about 4.6% 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 | 4.5% |
| Stretch from the 200-day average | it is trading 10.0 daily ranges below its 200-day average price (31.3% 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 | 10.0 daily ranges below its 200-day average |

| Since a bullish engulfing | 6 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 | 6 sessions ago |
Price gaps
2
| Gap at the open | it opened on 2026-08-21 0.9% above the previous session's close — an overnight gap, the part of the move that happened while the market was shut, and had not traded back through that level by the close | +0.9% |
|---|---|---|
| Gap filled | a 5.7% gap down opened on 2026-08-06 has been "filled" 10 sessions ago — price traded back through the level the gap left behind, and it took 1 session to close | 10 sessions ago |

|---|---|---|
| Bearish technical signals | 5 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, MACD momentum is negative, 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 10% 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 12.3% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | -10.3% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 19% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $9.80 — a volume-weighted average of daily closes over 157 sessions, not a true tick-by-tick VWAP. | -19.4% |
|---|---|---|
| Vs the average paid since it last reported | the price is 3% 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 $8.14 — a volume-weighted average of daily closes over 13 sessions, not a true tick-by-tick VWAP. | -2.9% |

ERII last closed at $7.90 on 2026-08-21. Since 2024-08-21 it has turned at 0 prices below its last close and 13 above; the 3 nearest above are listed, nearest first.

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 2026-08-21.

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.

reported quarterly holdings change (2025-12-31 → 2026-03-31): 0 new, 4 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)
ERII had 2,774,253 shares of reported short interest as of the 2026-07-31 FINRA settlement date (delayed, bi-monthly; not real-time).
ERII had 5.43% 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 3.56 days to cover at the same settlement.
- Reported short interest (shares) 2,774,253
- Short interest (% of shares outstanding) 5.43%
- Prior settlement (shares) 2,712,281
- Reported change 2.28%
- Days to cover (reported) 3.56
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.
