How HYLIION HOLDINGS CORP looks technically
HYLIION HOLDINGS CORP (HYLN) is trading 15.9% 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 105 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 17, below the 25 that marks a real trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 44, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 3 trading days ago (its momentum flipped negative). It just made a new 20-day low, its first since 2026-09-04, breaking below its recent trading range. It is 55.6% below its highest point of the past year.
Trend
7
| Distance from the 200-day | it is trading 15.9% above its 200-day average, the long-term trend line — a longer-term uptrend | +15.9% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $3.86 | $3.86 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $3.25 | $3.25 |
| 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 low 10 calendar days ago — the swings before that are what the structure reading is measured on | 10 sessions |
| Since the 50/200 cross | its 50-day average crossed above its 200-day average about 105 trading days ago — a "golden cross", a bullish long-term signal | 105 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 17, below the 25 that marks a real trend) | 17.3 |
Momentum
3
| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 44, neither overbought (above 70) nor oversold (below 30) | 43.8 |
|---|---|---|
| Position in its 14-day range | it is trading near the bottom of its 14-day range ($3.67 to $4.68) — its "stochastic" reading is 10 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. | 9.8 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bearish about 3 trading days ago (its momentum flipped negative) | 3 sessions |
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 55.6% below its 52-week high (its highest price of the past year) | -55.6% |
| Above the 52-week low | it is 141.7% above its 52-week low (its lowest price of the past year) | +141.7% |
| Below the 52-week high | it is 55.6% below its highest point of the past year | 55.6% |
| Since a 20-day breakout | it just made a new 20-day low, its first since 2026-09-04, breaking below its recent trading range | 1 session |
| Since a 55-day breakout | it made a new 55-day high about 5 trading days ago | 5 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 ($1.58 to $8.10), and it has given back well over two thirds of its rise from last year’s low — 66% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $3.86 to $4.07. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 66.4% |
| From the all-time high | it is 80.6% below its all-time high | -80.7% |
| Nearest price level | it is trading 8.7% below a resistance level at $4.10 — a price it turned at twice since 2024-11-25, most recently on 2026-09-08. Since 2024-10-08 it has 10 such levels below the current price and 1 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | +8.7% |
| 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 627.7% above its all-time low | +627.7% |
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 90% of it) | 10th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $0.2953 between its high and its low — about 7.8% 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 | $0.2953 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $3.69 and $4.51 — 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 | $3.69 – $4.10 – $4.51 |
| Typical daily range (% of price) | its price moves about 7.8% 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 | 7.8% |
| Stretch from the 200-day average | it is trading 1.8 daily ranges above its 200-day average price (15.9% 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 | 1.8 daily ranges above its 200-day average |

Price gaps
2
| Gap at the open | it opened on 2026-10-08 1.6% below 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 | -1.6% |
|---|---|---|
| Gap filled | a 2.6% gap up opened on 2026-10-02 has been "filled" 3 sessions ago — price traded back through the level the gap left behind, and it took 1 session to close | 3 sessions ago |
Price streaks
1
| Closing streak | it has closed lower 4 sessions in a row, a -16.78% 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 | 3 of the 9 technical signals we can compute for it are currently in a bearish state: a fresh 20-day low, MACD momentum is negative, trading below the Ichimoku cloud — these describe past price behaviour, not a forecast | 3 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 2.3% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-09-01 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 51.7% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | -2.3% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 16% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $4.51 — a volume-weighted average of daily closes over 190 sessions, not a true tick-by-tick VWAP. | -16.4% |
|---|---|---|
| Vs the average paid since it last reported | the price is 3% below the average price paid since it last reported on 2026-08-11 (its 10-Q), so the typical buyer over that stretch is under water. That average is $3.89 — a volume-weighted average of daily closes over 42 sessions, not a true tick-by-tick VWAP. | -3.0% |
Price levels it has turned at before
HYLN last closed at $3.77 on 2026-10-08. Since 2024-10-08 it has turned at 10 prices below its last close and 1 above; the 3 nearest below and the nearest above are listed, nearest first.
| Level | Side | Distance | Evidence |
|---|---|---|---|
| $4.10 | Resistance | 8.7% above the last close | turned there twice · 2024-11-25 to 2026-09-08 |
| $2.56 | Support | 32.1% below the last close | turned there three times · 2025-01-24 to 2025-10-16 |

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.

HYLN had 8.95% of its shares outstanding sold short as of the 2026-09-15 FINRA settlement date (percent of FLOAT would be higher — float is not disclosed in the source). FINRA reported 10.5 days to cover at the same settlement.

Reported to FINRA as of the 2026-09-15 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.
