What stands out
- McClelland Bruce William accounts for 100% of comparable reported purchase value; buyer breadth and value are different measures.
Price vs insider buying
Verified historical closes are unavailable; filing evidence remains below.
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
Independent evidence does not object: the purchases themselves carry bull lines (bought in the last two weeks); short sellers were checked and none crosses a bear threshold. No data is held for: share price and trading, company results, company actions.
- The insider purchases themselvesBullbought in the last two weeks Bearone buyer only4 checked, under the threshold · 3 missing
- Share price and tradingno data held
- Short sellers2 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
- The latest purchase is 6 days old (2026-10-30). 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.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- The company's market value is not captured, so the purchases cannot be stated as a share of the business or of its trading volume.
- No earnings, margin or cash-flow figures are captured for this company. The latest annual and interim reports are where to check whether the business is improving or deteriorating.
- 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 1 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 of $96k in 180 days. Bull from $1.0M, bear when all purchases total under $25k.
- BearNo insider sale is recorded in the same 180 days.
- BearOver the last 5 trading days to 2026-11-05, 33% of this stock's off-exchange volume was sold short; over the 60 days before, 51%. 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.
- BearFINRA short interest on 2026-10-15 equals 3.4 days of average trading volume, up 3.8% from the previous report. Counted for the bear side from 10 days, or from 10% of the shares outstanding.

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+7.4 / 25
The value bought, net of any insider sales
Buyers' roles+13.0 / 20
Lower in the company scores higher: in the backtest, purchases by the most senior insiders did worse
How recent+9.1 / 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 little · most senior buyer: President & CEO; the most senior score lowest
- ✓ Recent buying · latest purchase 2026-10-30
Buyers' roles follow the US order of roles: CEOs, chairs and 10% owners score lowest.
Buying concentration
100%
Largest buyer：McClelland Bruce William · 96k USD
Purchases counted, before sales：96k 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 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.

Results dates are the company's 8-K filings to the SEC under Item 2.02 (results of operations); one filed after the close counts from the next session. 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. Facts only; this does not change the score or rank.

Prices and reported values remain in the filing currency and its major unit (for example, UK pence are parsed as GBP). The screen-level $ aggregate is separately FX-normalised for research ranking, not a trade-date conversion.

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.
