How HYLIION HOLDINGS CORP looks technically
HYLIION HOLDINGS CORP (HYLN) is trading 13.7% 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 72 trading days ago — a "golden cross", a bullish long-term signal. There is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 18, below the 25 that marks a real trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 37, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 1 trading day ago (its momentum flipped negative). It made a new 20-day low about 18 trading days ago. It is 60.8% below its highest point of the past year.
Trend
7
| Distance from the 200-day | it is trading 13.7% above its 200-day average, the long-term trend line — a longer-term uptrend | +13.7% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $4.54 | $4.54 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $2.93 | $2.93 |
| 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 9 calendar days ago — the swings before that are what the structure reading is measured on | 9 sessions |
| Since the 50/200 cross | its 50-day average crossed above its 200-day average about 72 trading days ago — a "golden cross", a bullish long-term signal | 72 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 18, below the 25 that marks a real trend) | 18.4 |
Momentum
3
| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 37, neither overbought (above 70) nor oversold (below 30) | 36.5 |
|---|---|---|
| Position in its 14-day range | it is trading right at the bottom of its 14-day range ($3.27 to $5.45) — its "stochastic" reading is 3 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. | 3.0 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bearish about 1 trading day ago (its momentum flipped negative) | 1 session |
Range
12
| 52-week high | its highest closing price over the past year (about 252 trading days) was $8.49 | $8.49 |
|---|---|---|
| From the 52-week high | it is 60.8% below its 52-week high (its highest price of the past year) | -60.8% |
| Above the 52-week low | it is 126.5% above its 52-week low (its lowest price of the past year) | +126.5% |

| Since a 20-day breakout | it made a new 20-day low about 18 trading days ago | 18 sessions |
| Since a 55-day breakout | it made a new 55-day high about 45 trading days ago | 45 sessions |
| All-time high | its highest closing price on record is $19.48 (set on 2021-02-22) | $19.48 |
| Given back of the 52-week move | over the past year its closes ranged ($1.53 to $8.10), and it has given back well over two thirds of its rise from last year’s low — 73% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $3.83 to $4.04. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 72.6% |
| From the all-time high | it is 82.9% below its all-time high | -82.9% |
| Nearest price level | it is trading 23.1% above a support level at $2.56 — a price it turned at three times since 2025-01-24, most recently on 2025-10-16. Since 2024-08-21 it has 10 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. | -23.1% |
| All-time low | its lowest closing price on record is $0.5181 (set on 2023-10-11) | $0.5181 |
| Above the all-time low | it is 542.7% above its all-time low | +542.7% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are about average versus its own recent 6-month history | 54th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $0.4513 between its high and its low — about 13.6% 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 | $0.4513 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $3.27 and $4.29 — 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 | $3.27 – $3.78 – $4.29 |
| Typical daily range (% of price) | its price moves about 13.6% in a typical session — among the most volatile in the catalog. 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 | 13.6% |
| Stretch from the 200-day average | it is trading 0.9 daily ranges above its 200-day average price (13.7% 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 | 0.9 daily ranges above its 200-day average |

Candlestick patterns

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 3.4% below the previous close 3 sessions ago and has not traded back through the level it left behind at 4.09 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | -3.4% |
| Gap filled | a 4.1% gap up opened on 2026-08-13 has been "filled" 3 sessions ago — price traded back through the level the gap left behind, and it took 3 sessions to close | 3 sessions ago |
Price streaks
1
| Closing streak | it has closed lower 4 sessions in a row, a -18.58% move over the run — an unbroken run of down days, which describes what has already happened and says nothing about the next session | 4 sessions down |

Signal agreement
2
| Bullish technical signals | 4 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, trading above its 200-day average, outperforming the market over 6 months, near the bottom of its 14-day range (oversold) — these describe past price behaviour, not a forecast | 4 of 9 |
|---|---|---|
| Bearish technical signals | 2 of the 9 technical signals we can compute for it are currently in a bearish state: MACD momentum is negative, trading below the Ichimoku cloud — these describe past price behaviour, not a forecast | 2 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 34% 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 thin, spanning 1.7% of the share price, which is taken to mean a barrier that gives way easily. | -34.3% |
|---|
Volume-weighted price
1
| Vs this year’s average price paid | the price is 28% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $4.60 — a volume-weighted average of daily closes over 157 sessions, not a true tick-by-tick VWAP. | -27.6% |
|---|

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 2026-08-21.

Analyst EPS estimate for HYLN
- Consensus EPS estimate-$0.07 next reporting period, 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. Informational only, not a forecast and not advice.

- Notes:
- The newer filing text appears truncated at the end ('where excess heat is effic'), making full comparison of the science section incomplete
- Annual report reference change from 2024 to 2025 is expected given the filing dates and may reflect routine updating rather than substantive change

AI-assisted comparison of two SEC filing sections. It describes wording and theme changes only, makes no materiality, legal, or investment judgement, and is not financial advice. Informational only — not financial advice.
Insider activity (SEC Form 4)
No open-market insider purchases or sales are on record for HYLN — 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)
5 institutional 13F filers reported holding HYLN as of 2026-03-31 (quarter-end position, filed within 45 days).
- Distinct 13F filers 5
- Reported shares held 12,561,421
- Reported value $22,108,101
reported quarterly holdings change (2025-12-31 → 2026-03-31): 0 new, 3 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. Informational only — not financial advice.
Short interest (FINRA)
HYLN had 16,560,477 shares of reported short interest as of the 2026-07-31 FINRA settlement date (delayed, bi-monthly; not real-time).
HYLN had 9.27% 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 5.92 days to cover at the same settlement.
- Reported short interest (shares) 16,560,477
- Short interest (% of shares outstanding) 9.27%
- Prior settlement (shares) 15,120,944
- Reported change 9.52%
- Days to cover (reported) 5.92
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.
