How Inspire Medical Systems looks technically
Inspire Medical Systems (INSP) is trading 8.4% 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 351 trading days ago — a "death cross", a bearish long-term signal. A strong uptrend is in place — ADX, a 0–100 trend-strength gauge, is 28, with buyers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 66, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bullish about 2 trading days ago (its momentum flipped positive). It made a new 20-day high about 14 trading days ago. It is 57.6% below its highest point of the past year.
Trend
8
| Distance from the 200-day | it is trading 8.4% below its 200-day average, the long-term trend line — a long-term downtrend | -8.4% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $51.05 | $51.05 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $68.07 | $68.07 |
| 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 17 calendar days ago — the swings before that are what the structure reading is measured on | 17 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 66.205. 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 below its 200-day average about 351 trading days ago — a "death cross", a bearish long-term signal | 351 sessions |
| Trend strength (14-day ADX) | a strong uptrend is in place — ADX, a 0–100 trend-strength gauge, is 28, with buyers in control | 27.6 |
Momentum

| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 66, neither overbought (above 70) nor oversold (below 30) | 66.4 |
|---|---|---|
| Position in its 14-day range | it is trading in the upper half of its 14-day range ($55.44 to $66.20) — its "stochastic" reading is 64 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. | 64.3 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, turned bullish about 2 trading days ago (its momentum flipped positive) | 2 sessions |
Range
12
| 52-week high | its highest closing price over the past year (about 252 trading days) was $147.03 | $147.03 |
|---|---|---|
| From the 52-week high | it is 57.6% below its 52-week high (its highest price of the past year) | -57.6% |
| Above the 52-week low | it is 60.3% above its 52-week low (its lowest price of the past year) | +60.3% |

| Since a 55-day breakout | it made a new 55-day high about 14 trading days ago | 14 sessions |
| All-time high | its highest closing price on record is $330.00 (set on 2023-07-14) | $330.00 |
| Given back of the 52-week move | over the past year its closes ranged ($40.05 to $143.99), and it has recovered roughly a quarter of its fall from last year’s high — 21% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $104.28 to $107.61. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 21.5% |
| From the all-time high | it is 81.1% below its all-time high | -81.1% |
| Nearest price level | it is trading 7.8% above a support level at $57.52 — a price it turned at twice since 2026-02-24, most recently on 2026-05-04. Since 2024-08-21 it has 5 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. | -7.8% |
| All-time low | its lowest closing price on record is $22.50 (set on 2018-05-03) | $22.50 |
| Above the all-time low | it is 177.2% above its all-time low | +177.2% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are about average versus its own recent 6-month history | 63rd percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $2.77 between its high and its low — about 4.5% 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 | $2.77 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $48.46 and $65.74 — 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 | $48.46 – $57.10 – $65.74 |
| Typical daily range (% of price) | its price moves about 4.5% 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 2.1 daily ranges below its 200-day average price (8.4% 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 | 2.1 daily ranges below its 200-day average |

Price gaps
3
| Gap at the open | it opened on 2026-08-21 0.2% below 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 | -0.2% |
|---|---|---|
| Open gap | it gapped 22.9% above the previous close 13 sessions ago and has not traded back through the level it left behind at 52.22 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | +22.9% |
| Gap filled | a 5.3% gap down opened on 2026-07-28 has been "filled" 18 sessions ago — price traded back through the level the gap left behind, and it closed again during the very session that opened it | 18 sessions ago |
Price streaks

| 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 |

Signal agreement
2
| Bullish technical signals | 3 of the 9 technical signals we can compute for it are currently in a bullish state: a strong uptrend, with buyers in control, MACD momentum is positive, trading above the Ichimoku cloud — these describe past price behaviour, not a forecast | 3 of 9 |
|---|---|---|
| Bearish technical signals | 3 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, lagging the market over 6 months — these describe past price behaviour, not a forecast | 3 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading 29% 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 thin, spanning 0.6% of the share price, which is taken to mean a barrier that gives way easily. | +28.8% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 7% above the average price paid so far this year, so the typical buyer over that stretch is showing a gain. That average is $58.24 — a volume-weighted average of daily closes over 155 sessions, not a true tick-by-tick VWAP. | +7.1% |
|---|---|---|
| Vs the average paid since it last reported | the price is 4% above the average price paid since it last reported on 2026-08-03 (its 10-Q), so the typical buyer over that stretch is showing a gain. That average is $59.75 — a volume-weighted average of daily closes over 15 sessions, not a true tick-by-tick VWAP. | +4.4% |
Price levels it has turned at before

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 $66.20.
It is the only labelling that fits these swings, though its proportions are not the textbook ones. It was chosen from 3 labellings that survived the rules, counting shorter readings of the same bars.
This labelling was already in place when we began recording count changes on 2026-08-13, so how long it has stood is not something we can say yet.
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.

- Consensus EPS estimate$0.08701 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.

Management's Discussion & Analysis (MD&A)
The two filings could not be meaningfully compared for this section.
Risk Factors
- Added:
- Reference to 'Annual Report on Form 10-K for the fiscal year ended December 31, 2025' added in newer filing (2026-05-04)
- Removed:
- Reference to 'Item 1A. Risk Factors' in this Quarterly Report' changed to reference the Annual Report on Form 10-K
- Reworded:
- Newer filing (2026-05-04) states risk factors are found in 'Item 1A. Risk Factors of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025' versus older filing (2025-11-03) which stated 'Item 1A. Risk Factors' in this Quarterly Report'
- Notes:
- The two filings cover different reporting periods (Q1 2026 vs Q3 2025) and therefore contain entirely different financial statements with different balance sheet dates, income statement periods, and cash flow periods. The Risk Factors introductory text is nearly identical except for one citation change.
- The bulk of the provided text consists of financial statements (balance sheets, income statements, cash flows, stockholders' equity statements) which are expected to differ due to different reporting periods and are not part of the Risk Factors section comparison.

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.
Institutional ownership (13F)

- Reported value $292,465,099
reported quarterly holdings change (2025-12-31 → 2026-03-31): 0 new, 3 increased, 3 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)
INSP had 3,920,330 shares of reported short interest as of the 2026-07-31 FINRA settlement date (delayed, bi-monthly; not real-time).
INSP had 13.6% 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 5.02 days to cover at the same settlement.
- Reported short interest (shares) 3,920,330
- Short interest (% of shares outstanding) 13.6%
- Prior settlement (shares) 4,344,629
- Reported change -9.77%
- Days to cover (reported) 5.02
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.
