WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+7.0 / 35
How many distinct insiders bought in the cluster
Purchase size+3.7 / 25
Purchase value relative to company size and liquidity
Role+5.0 / 20
The seniority and relevance of participating insiders
Recency+5.9 / 10
How recently the purchases occurred
Conviction+10.0 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Purchase size is modest relative to the model scale
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
The role contribution follows the US model's seniority ladder.
Buying concentration
100%
Largest buyer：Dizon Romeo R · 31k USD
Gross qualified purchase transaction-line value：31k USD
The headline $ total is net buying for the screen; this module uses gross qualified purchase transaction-line values in the filing currency, so the amounts can differ. The current 15-day buyer-breadth input counts distinct buyers; value concentration is disclosed separately here.
This is a ranking under the current US screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider vs stock price
10 purchase day(s), 11 purchase line(s) in the 180-day window.
Daily close (USD)Day with an insider purchase
Markers sit on the closing price of the transaction day. They show when insiders traded, not the price they paid or received. "Since" compares that day's close with the last close shown; it is what happened at this company, not a forecast.
If you had followed the purchase
Each row starts on the first close on or after the day a purchase was made public, the earliest a reader could have acted, and ends on the last close shown above.

5 of 11 disclosure day(s) ended ahead of the median peer stock.
Close to close, before costs, taxes, dividends and currency moves. The peer is the median of the other stocks on the same exchange for which this site holds prices (1093 here), not an index. This is what happened, not a forecast: across all purchases on this site the typical gap is close to zero.
Insider timeline
One insider bought, 10 times, the latest (16 Sep). The share closed at 0.61 that day and at 0.89 most recently (+45.9%).
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, −16.8% over these six months
The closing price of each day, from 1.07 on 2026-04-21 to 0.89 on 2026-10-09. 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, −11.0%
Taken from the 1230 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 −16.8%, the typical one −11.0%, 5.8 points behind. It is not an index and not a comparison within one industry.

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 insider purchases themselvesBearone buyer only, usual level for this company6 checked, under the threshold · 1 missing
- Share price and trading2 checked, under the threshold
- Short sellers2 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
Nothing held here goes beyond the fact that an insider bought.
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.
- Buying at this level is normal here: 3 insiders bought in the previous 180 days and 1 in this one.
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.
Checked and under the threshold: 10
- EitherNet purchases of $31k in 180 days. Bull from $1.0M, bear when all purchases total under $25k.
- BearNo insider sale is recorded in the same 180 days.
- EitherThe latest purchase is 32 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed −11% over six months (three months −17%, one month +31%) and stands 46% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −17% and the median of 219 Healthcare companies changed −12%: behind by 5 points. Counted for the bear side from 20 points behind.
- BearNone of the 10 purchase filings ticks Form 4's 10b5-1 box.
- BearOver the last 5 trading days to 2026-10-16, 27% of this stock's off-exchange volume was sold short; over the 60 days before, 53%. The market's median is 50%. 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.
- Bull10 of 10 purchase filings state the shares held before and after. The largest addition to an existing holding took it from 177,406 to 185,306 shares (+4.5%). Counted for the bull side from +100%, for the bear side below +1%.
- BearNo insider filing in the last 180 days opened a hedge on this stock.
- BearFINRA short interest on 2026-09-30 equals 3.5 days of average trading volume and 0.75% of the 17,564,912 shares outstanding, down 18% from the previous report. Counted for the bear side from 10 days, or from 10% of the shares outstanding.

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.

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.

Filing evidence
These are underlying national-feed records from the 365-day window ending on the saved ranking snapshot. The score uses only the latest 180 days; older qualifying equity purchases remain visible for audit but do not enter the current score. The original filer, role, transaction classification, instrument, price, volume, value and source fields are retained. The first three rows are shown; remaining records can be unfolded for audit.
