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+21.7 / 25

Purchase value relative to company size and liquidity

Role+0.0 / 20

The seniority and relevance of participating insiders

Recency+4.7 / 10

How recently the purchases occurred

Conviction+7.5 / 10

How clearly buying stands out from other activity

What is holding the score back?

  • ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
  • ⚠ 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.

Largest buyer：KNIGHT LESTER B · 6.55m USD
Gross qualified purchase transaction-line value：6.55m 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.

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.

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.

×A sale

A cross is one insider's sales on one day. People sell to pay tax, to cash in share awards or to hold less of one company, so a sale says less than a purchase does. When someone bought and sold on the same day, the cross sits beside the dot. The totals are under “Purchases against sales” below.

Blue line: this share's price, −18.4% over these six months

The closing price of each day, from 335.32 on 2026-04-21 to 273.47 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 −18.4%, the typical one −11.0%, 7.4 points behind. It is not an index and not a comparison within one industry.

Shares of the reported value of insider transactions in the 180-day window. Sales include disposals for tax, at option exercise or under a pre-set plan, which say little about an insider's view. The split describes what was disclosed; it is not a signal.

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 (large purchases), while share price and trading argue against (price trails its sector). No data is held for: company results, company actions.

  • The insider purchases themselvesBulllarge purchases Bearone buyer only, insiders also sold5 checked, under the threshold · 1 missing
  • Share price and tradingBearprice trails its sector1 checked, under the threshold
  • Short sellers2 checked, under the threshold
  • Company results2 missing
  • Company actionsno data held

Bull case · the buying is informative

  • Insiders committed a net $4.9M of their own money in 180 days.

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.
  • Insiders also sold $1.7M in the same 180 days, 25% of the amount bought.
  • Share price and tradingOver three months the share price changed −26% and the median of 143 Financial Services companies changed −1.2%: 24 points behind. The market has marked this company down against its own sector.

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: 8
  • 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.
  • EitherThe latest purchase is 46 days old. Bull up to 14 days, bear from 90.
  • BearThe share price changed −13% over six months (three months −26%, one month −11%) and stands 28% below its 52-week high. Counted for the bear side from a fall of 20%.
  • BearNone of the 1 purchase filing ticks Form 4's 10b5-1 box.
  • BearOver the last 5 trading days to 2026-10-16, 35% of this stock's off-exchange volume was sold short; over the 60 days before, 44%. 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.
  • Bull1 of 1 purchase filing states the shares held before and after. The largest addition to an existing holding took it from 143,000 to 163,000 shares (+14%). 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 1.8 days of average trading volume, up 14% from the previous report. Counted for the bear side from 10 days, or from 10% of the shares outstanding.

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.
