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.

Daily close (USD)Day with an insider purchaseTwo or more insiders the same day

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.

0 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 (1086 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

8 insiders bought within 15 days, 11 Aug to 25 Aug: 6 Executive, 1 CEO / chair, 1 CFO. 3 more bought afterwards. The share closed at 47.60 on the first of those days and at 36.20 most recently (−23.9%). That week 200 companies across United States disclosed insider purchases, more than in 85% of the last 26 weeks: insiders often buy together when a closed period ends, so the timing alone says less than it seems.

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.

▮Purple band: several insiders bought within 15 days

The band marks the stretch with the most different buyers: at most 15 days long and at least two people. Here it is 11 Aug – 25 Aug, with 8 insiders. Only the strongest stretch is marked. Several people deciding the same thing is harder to explain by one person's private reasons, but insiders often buy together just after a closed period ends, so compare it with the grey weekly bars.

Blue line: this share's price, −36.6% over these six months

The closing price of each day, from 57.12 on 2026-04-21 to 36.20 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 −36.6%, the typical one −11.0%, 25.6 points behind. It is not an index and not a comparison within one industry.

▂Grey bars: companies across United States disclosing purchases each week

A taller bar is a week in which more companies disclosed insider purchases. The purple bar is the week of the band above: 200 companies, number 4 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

1 more insiders traded in the window and are not drawn.

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 (several insiders together, large purchases, purchase added much to the holding), while share price and trading argue against (price down over six months). No data is held for: company results, company actions.

Bull case · the buying is informative

9 insiders bought within 15 days (2026-08-11 to 2026-08-26). Several people reaching the same decision at the same time is hard to put down to one person's circumstances.
Insiders committed a net $5.4M of their own money in 180 days.
17 of 17 purchase filings state the shares held before and after. In 1 of them the filer reported no shares of the company before the purchase. The largest addition to an existing holding took it from 5,377 to 10,637 shares (+98%). A holding here is one way of owning the shares: directly, or through one named trust or entity.

Bear case · discount it

Share price and tradingThe share price is down 38% over six months (three months −26%, one month −10%) and stands 45% below its 52-week high. Insiders have bought into a fall the market has not reversed.
The 7 earlier purchases by Hill Jaime trailed S&P 500 ETF (SPY adjusted close) by a median 10.0% over the following 60 trading days.

Evidence still missing

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: 9, 1 close to it

BearThe largest buyer accounts for 68% of the value bought. Counted for the bear side from 80%. close to the threshold
Either11 insiders bought in the last 180 days and 6 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.
EitherThe latest purchase is 46 days old. Bull up to 14 days, bear from 90.
BearOver three months the share price changed −26% and the median of 46 Basic Materials companies changed −15%: behind by 11 points. Counted for the bear side from 20 points behind.
BearNone of the 17 purchase filings ticks Form 4's 10b5-1 box.
BearOver the last 5 trading days to 2026-10-16, 60% of this stock's off-exchange volume was sold short; over the 60 days before, 47%. 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.
BearFINRA short interest on 2026-09-30 equals 2.9 days of average trading volume, up 15% 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.

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