Buying concentration
100%
Largest buyer：Cha Albert; FHMLSP, L.L.C.; FHMLSP, L.P.; Frazier Life Sciences Holdings II LLC; Frazier Life Sciences Public Fund, L.P. · 3.00m USD
Gross qualified purchase transaction-line value：3.00m 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
1 purchase day(s), 1 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.
| Made public | Insiders | In this stock, now | In the median peer stock, now | Difference |
|---|---|---|---|---|
| 2026-10-15 | 1 | 987 −1.3% | 995 −0.5% | −9 −0.9 pts |
0 of 1 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 (111 here), not an index. This is what happened, not a forecast: across all purchases on this site the typical gap is close to zero.

●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.

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 (large purchases, 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 themselvesBulllarge purchases, bought in the last two weeks Bearone buyer only3 checked, under the threshold · 3 missing
- Share price and tradingno data held
- Short sellers1 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
- Insiders committed a net $3.0M of their own money in 180 days.
- The latest purchase is 3 days old (2026-10-15). 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: 4
- 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.
- BearNo insider sale is recorded in the same 180 days.
- BearOver the last 3 trading days to 2026-10-16, 44% of this stock's off-exchange volume was sold short. 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.
- BearNo insider filing in the last 180 days opened a hedge on this stock.

Why did it change?
Less than 30 days of comparable history is available, so factor movement is not yet decomposed.

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.

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. Other transaction types are retained but excluded from the score.
