BULL VS BEAR
Two readings of this buying
The same filings, read two ways. Each line is a fact stored for this company with the number behind it, and appears only when that number crosses a fixed threshold. Neither side is a forecast and no winner is declared.
Where the evidence comes from
The two kinds of evidence disagree: the purchases themselves carry bull lines (bought in the last two weeks), while share price and trading argue against (price down over six months); short sellers argue against (high short interest); company results argue against (loss-making). No data is held for: company actions.

- Company resultsBearloss-making1 missing
- Company actionsno data held
Bull case · the buying is informative
- The latest purchase is 1 day old (2026-11-05). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.
- Company resultsThe company is loss-making on the latest captured figures: profit margin −120%, return on equity −83%.
- Share price and tradingThe share price is down 39% over six months (three months −24%, one month −16%) and stands 62% below its 52-week high. Insiders have bought into a fall the market has not reversed.
- Short sellersFINRA short interest on 2026-10-15 was 8,309,808 shares, 8.3 days of average trading volume and 14% of the 60,469,687 shares outstanding, up 6.1% from the previous report: other investors hold a sizeable position the opposite way.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- Only one reading of profitability is held (profit margin −120%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- The 10b5-1 box of these Form 4 filings has not been read, so whether the purchases followed a pre-arranged plan is not known.
- Form 4 states the shares held after each trade. This site reads that from the SEC's quarterly data, which is published after a quarter ends, so it does not have it yet for these filings. Whether a purchase added 1% to a personal stake or doubled it is in the filing, not on this page.
Checked and under the threshold: 6
- Either1 insider bought in the last 180 days and 0 in the 180 days before. Bull when the number at least doubles and rises by two; bear when at least two bought before and no more buy now.
- EitherNet purchases equal 0.02% of the company's market value. Bull from 0.10%, bear below 0.01%.
- BearNo insider sale is recorded in the same 180 days.
- BearOver three months the share price changed −24% and the median of 224 Healthcare companies changed −19%: behind by 5 points. Counted for the bear side from 20 points behind.
- BearOver the last 5 trading days to 2026-11-06, 56% of this stock's off-exchange volume was sold short; over the 60 days before, 50%. The market's median is 47%. This is trading volume, not a position: a market maker who sells short and covers the same day is counted, so about half of all volume is short on an ordinary day. It is shown for comparison and counts for neither side.
- BearNo insider filing in the last 180 days opened a hedge on this stock.
Both columns arrange stored facts only. They do not change the insider score or the ranking and are not investment advice.

WHY THIS SIGNAL?
Score anatomy
Each bar is that part's points in the score; the five parts add up to the score.
Number of buyers+7.0 / 35
How many different insiders bought within 15 days
Amount bought+4.3 / 25
The value bought, net of any insider sales
Buyers' roles+20.0 / 20
Lower in the company scores higher: in the backtest, purchases by the most senior insiders did worse
How recent+9.8 / 10
How long ago the latest purchase took place
Buying against selling+10.0 / 10
Lower when insiders also sold
What is holding the score back?
- ⚠ Few buyers · fewer than 4 different insiders
- ⚠ The amount bought is small on the score's scale
- ✓ Buyers' roles add a lot · the buyers are below the top of the company
- ✓ Recent buying · latest purchase 2026-11-05
Buyers' roles follow the US order of roles: CEOs, chairs and 10% owners score lowest.
Buying concentration
100%
Largest buyer：Duncan Charles Cliff · 38k USD
Purchases counted, before sales：38k USD
The amount at the top of the page is purchases minus sales; this one counts purchases only, in the filing currency, so the two can differ. The score counts how many people bought; this shows separately who bought the most.
This is a ranking under the current US screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider timeline
One insider bought, 3 times, the latest (5 Nov). The share closed at 3.59 that day and at 3.82 most recently (+6.4%).
Tap an item for what it means.
●A purchase: the bigger the dot, the more was bought
Each dot is one insider's purchases on one day. The dot's area follows the amount: the largest purchase here gets the largest dot. Hold the pointer over a dot to see the date and the amount.
Blue line: this share's price, −39.1% over these six months
The closing price of each day, from 6.27 on 2026-05-11 to 3.82 on 2026-11-06. The line has no scale; read it for high and low: a dot on a low stretch was bought cheaply, a dot on a high stretch was not.
Dashed line: the typical stock on the same exchange, −9.6%
Taken from the 1644 other stocks on the same exchange that this site holds prices for. Each is measured from the first day of the window, and every day the middle one is drawn. It starts where the blue line starts, so the gap between the two is the difference: this share −39.1%, the typical one −9.6%, 29.4 points behind. It is not an index and not a comparison within one industry.

Insider profile outcomes
Historical performance following insider filings. The company role is translated below each name while preserving the original title.
- Excess return = stock return − S&P 500 ETF (SPY adjusted close) return over the same period.
- Hit rate = completed events with positive excess return ÷ total completed events.
- Price coverage = valid point-in-time prices ÷ events mature enough for that period.
- Returns start on the first shared trading session on or after publication.
- Small-sample rule: n<5 is shown for transparency and is not scored.
Events are disclosure-level observations; related disclosures published on the same date may share a return path and may not be statistically independent. This research enrichment does not affect the insider score or ranking.
Signal outcomes
Calculated from immutable US ranking snapshots; excess return is stock return minus SPY return. Newly saved snapshots remain pending until each forward horizon matures. This never affects the US score.

Source: SEC, Schedules 13D and 13G, filed in a structured format since 18 December 2024; earlier filings are not read, so a holder that has not filed since then is not shown. 13D: the holder may seek to influence the company (activists, founders, strategic holders); it must amend within two business days of a change of 1% or more. 13G: the holder states it holds passively; it amends within 45 days after the quarter in which its holding changed materially, so a figure can be months old. The percentage is the filer's own, of the class of shares it names. Context only; not part of the score.

Purchases are open-market buys reported on Form 4 (code P), by trade date; a Form 4 can arrive two business days after the trade, so the latest days can still fill in.

There is not yet a 30-calendar-day comparison; earlier scores are not reconstructed. These are raw signal scores saved when each full scoring run completed. They describe changes in research ranking, not price performance or returns.
Why did it change?
Less than 30 days of comparable history is available, so factor movement is not yet decomposed.
