How TENABLE HOLDINGS INC looks technically
TENABLE HOLDINGS INC (TENB) is trading 43.4% 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 70 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 13, below the 25 that marks a real trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 60, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bullish about 7 trading days ago (its momentum flipped positive). It made a new 20-day high about 3 trading days ago.
Trend
8
| Distance from the 200-day | it is trading 43.4% above its 200-day average, the long-term trend line — a longer-term uptrend | +43.4% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $35.70 | $35.70 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $27.21 | $27.21 |
| 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 |
| Wave structure | its recent swings can be read as a five-part upward sequence — what Elliott-wave chartists call an impulse — now in leg 3 of five; the labelling fails if price closes below 32.49. It is one of several labellings that fit, and it describes the swings already printed, not what comes next. The same swings also read as a three-part correction in leg C. | possible upward five-wave sequence, in wave 3 (one of several readings) |
| Since the 50/200 cross | its 50-day average crossed above its 200-day average about 70 trading days ago — a "golden cross", a bullish long-term signal | 70 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 13, below the 25 that marks a real trend) | 13.0 |
Momentum

| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 60, neither overbought (above 70) nor oversold (below 30) | 60.4 |
|---|---|---|
| Position in its 14-day range | it is trading near the top of its 14-day range ($32.49 to $40.06) — its "stochastic" reading is 86 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. | 86.1 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bullish about 7 trading days ago (its momentum flipped positive) | 7 sessions |
Range
12
| 52-week high | its highest closing price over the past year (about 252 trading days) was $43.67 | $43.67 |
|---|---|---|
| From the 52-week high | it is 10.7% below its 52-week high (its highest price of the past year) | -10.7% |
| Above the 52-week low | it is 148.0% above its 52-week low (its lowest price of the past year) | +148.0% |
| Below the 52-week high | it is 10.7% below its highest point of the past year | 10.7% |
| Since a 20-day breakout | it made a new 20-day high about 3 trading days ago | 3 sessions |
| Since a 55-day breakout | it is trading within its recent 55-day range, with no fresh breakout up or down | 0 sessions |
| All-time high | its highest closing price on record is $63.61 (set on 2022-04-14) | $63.61 |
| Given back of the 52-week move | over the past year its closes ranged ($16.04 to $42.65), and it has given back only a small part of its rise from last year’s low — 14% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $25.35 to $26.20. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 13.7% |
| From the all-time high | it is 38.7% below its all-time high | -38.7% |
| Nearest price level | it is trading 0.6% above a support level at $38.80 — a price it turned at twice since 2026-08-31, most recently on 2026-09-15. Since 2024-10-08 it has 15 such levels below the current price and 3 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | -0.6% |
| All-time low | its lowest closing price on record is $15.73 (set on 2026-04-10) | $15.73 |
| Above the all-time low | it is 148.0% above its all-time low | +148.0% |
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 75% of it) | 25th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $2.01 between its high and its low — about 5.2% 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 | $2.01 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $32.02 and $40.34 — 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 | $32.02 – $36.18 – $40.34 |
| Typical daily range (% of price) | its price moves about 5.2% 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 | 5.2% |
| Stretch from the 200-day average | it is trading 5.9 daily ranges above its 200-day average price (43.4% 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 | 5.9 daily ranges above its 200-day average |

Price gaps
3
| Gap at the open | it opened on 2026-10-08 at essentially the same price it closed at the session before — no meaningful overnight gap | -0.0% |
|---|---|---|
| Open gap | it gapped 2.7% above the previous close 18 sessions ago and has not traded back through the level it left behind at 30.11 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | +2.7% |
| Gap filled | a 2.4% gap down opened on 2026-09-28 has been "filled" 8 sessions ago — price traded back through the level the gap left behind, and it closed again during the very session that opened it | 8 sessions ago |

Signal agreement
2
| Bullish technical signals | 6 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, a fresh 20-day high, MACD momentum is positive, outperforming the market over 6 months, 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: near the top of its 14-day range (overbought) — these describe past price behaviour, not a forecast | 1 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 13% above 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 uptrend, with the band below acting as the level that would have to give way. The band itself is thin, spanning 0.0% of the share price, which is taken to mean a barrier that gives way easily. | +12.8% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 38% above the average price paid so far this year, so the typical buyer over that stretch is showing a gain. That average is $28.35 — a volume-weighted average of daily closes over 188 sessions, not a true tick-by-tick VWAP. | +37.6% |
|---|---|---|
| Vs the average paid since it last reported | the price is 10% above the average price paid since it last reported on 2026-07-29 (its 8-K), so the typical buyer over that stretch is showing a gain. That average is $35.46 — a volume-weighted average of daily closes over 51 sessions, not a true tick-by-tick VWAP. | +10.0% |
Price levels it has turned at before
TENB last closed at $39.01 on 2026-10-08. Since 2024-10-08 it has turned at 15 prices below its last close and 3 above; the 3 nearest below and the 3 nearest above are listed, nearest first.
| Level | Side | Distance | Evidence |

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 in leg 3 of five.
This labelling fails — stops being a possible reading at all — if it closes below $32.49.
This is one of several labellings that fit the same swings, so treat it as a reading rather than the reading. It was chosen from 2 labellings that survived the rules, counting shorter readings of the same bars.
On past moves of this shape the leg has usually ended somewhere between $41.41 and $46.92 — that is where it has tended to end if the count holds, not a forecast of where the price goes.
Alternate reading: The same swings also read as a three-part correction in leg C, which fails on a close below $32.49.
This reading has stood for 3 trading days, since 2026-10-06.
Read from daily closes as of 2026-10-08.
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.

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.

reported quarterly holdings change (2026-03-31 → 2026-06-30): 0 new, 4 increased, 1 decreased, 1 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)
TENB had 18,181,258 shares of reported short interest as of the 2026-09-15 FINRA settlement date (delayed, bi-monthly; not real-time).
TENB had 16.5% 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 3.03 days to cover at the same settlement.
- Reported short interest (shares) 18,181,258
- Short interest (% of shares outstanding) 16.5%
- Prior settlement (shares) 15,183,618
- Reported change 19.74%
- Days to cover (reported) 3.03
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.
