One of the biggest mistakes investors make is assuming that every insider purchase deserves the same level of attention.
It doesn't.
Every week, Canadian insiders file dozens of trading reports. Some represent little more than symbolic purchases. Others have historically preceded some of the biggest winners in the microcap market.
The challenge isn't finding insider buying—it's separating the meaningful signals from the noise.
Over the years, I've developed a simple framework for evaluating insider activity. While no single factor guarantees future returns, companies that score highly across multiple categories deserve a closer look.
Signal #1: Who Is Buying?
Weight: 25 Points
The identity of the buyer is the single most important factor.
Score
25 Points
Founder
Founder-CEO
Executive Chairman
20 Points
CEO
President
15 Points
CFO
COO
10 Points
Senior Vice President
5 Points
Independent Director
Founders consistently produce the strongest signals because they generally understand the business better than anyone else and already have substantial financial exposure.
When founders continue buying despite already owning millions of dollars worth of stock, investors should pay attention.
Signal #2: Was It an Open-Market Purchase?
Weight: 20 Points
This criterion is simple.
20 Points
Open-market purchase
0 Points
Option exercise
RSU vesting
Share grant
Deferred Share Unit
Bonus shares
Only voluntary purchases deserve full credit.
Buying shares with after-tax dollars demonstrates conviction.
Receiving shares as compensation does not.
Signal #3: How Meaningful Was the Purchase?
Weight: 15 Points
The absolute dollar amount matters far less than the purchase's significance to the insider.
Score
15 Points Purchase exceeds annual salary or appears financially meaningful.
10 Points Large purchase relative to previous insider transactions.
5 Points Moderate purchase.
0 Points Token purchase.
A $500,000 purchase from a CEO earning $300,000 annually tells a very different story than the same purchase by a billionaire founder.
Always consider context.
Signal #4: Are Multiple Insiders Buying?
Weight: 15 Points
Cluster buying is one of the strongest predictors of future outperformance.
Score
15 Points Three or more insiders buying.
10 Points Two insiders buying.
0 Points Single insider.
When several executives independently reach the same conclusion at roughly the same time, investors should take notice.
Signal #5: When Did They Buy?
Weight: 10 Points
Timing often reveals management's confidence.
Highest scores go to purchases made:
after disappointing earnings;
following a financing;
after a sharp share price decline;
during industry-wide weakness;
when investor sentiment is negative.
Buying when everyone else is selling frequently signals genuine conviction.
Signal #6: Existing Insider Ownership
Weight: 10 Points
Investors often overlook this factor.
If management already owns a meaningful percentage of the company, every additional purchase carries greater weight.
Score
10 Points Insiders own more than 20%.
8 Points 10–20%.
5 Points 5–10%.
0 Points Less than 5%.
Executives with significant ownership think like business owners rather than hired managers.
Signal #7: Is Share Dilution Under Control?
Weight: 5 Points
Nothing destroys shareholder value faster than constant dilution.
Even strong insider buying becomes less meaningful if management repeatedly issues stock.
Score
5 Points Share count stable or declining.
3 Points Minimal dilution.
0 Points Frequent equity financings.
The strongest insider signals often come from companies that generate sufficient cash flow to avoid regular equity issuance.

How to Interpret the Score
90–100 Points: Exceptional
These opportunities are rare.
Everything is lining up.
This deserves immediate research.
75–89 Points: Very Attractive
Strong insider conviction.
Likely worthy of a position if the business fundamentals support the investment.
60–74 Points: Interesting
Monitor closely.
May warrant additional due diligence or placement on a watchlist.
Below 60
Insider activity alone is unlikely to provide a sufficient edge.
Focus elsewhere.
Putting the Scorecard to Work
The best use of this framework is not to buy stocks simply because insiders are purchasing shares.
Instead, use it to prioritize your research.
Suppose you screen the Canadian market each month and identify twenty companies with insider purchases.
Perhaps only five score above 80.
Those five deserve your immediate attention.
From there, analyze the balance sheet, competitive advantages, valuation, management quality, capital allocation, customer concentration, and long-term growth prospects.
The scorecard narrows the field.
Fundamental analysis makes the final decision.
One Final Filter
There is one additional characteristic that often separates good insider buying from truly exceptional insider buying.
Look for companies where insiders are buying before positive developments become obvious to the market.
This might occur several months before:
accelerating revenue growth;
improving margins;
major contract wins;
strategic acquisitions;
industry recovery;
regulatory approvals; or
sustained profitability.
By the time these catalysts appear in quarterly results, much of the upside has often already been captured.
Insiders, however, frequently begin accumulating shares while those improvements are still invisible to outside investors.
That is precisely why insider buying remains one of the most valuable signals available to microcap investors.
Final Thoughts
Microcap investing has always been about uncovering information before it becomes widely recognized.
Meaningful insider buying is one of the few legally disclosed signals that allows investors to observe the actions—not just the words—of the people who know a business best.
When founders are buying, when several insiders are buying together, when purchases are made with personal cash after periods of market pessimism, and when dilution is under control, investors should pay attention.
The filings themselves won't tell you which company will become the next ten-bagger.
But they can tell you where to begin looking.
And in microcap investing, knowing where to look is often half the battle.
