Insider Activity Tracker

On the ASX Markets Announcements Platform (asx.com.au) - look for 'Change of Director's Interest Notice' (Appendix 3Y) and substantial-holder Forms 603/604/605. Aggregators like Market Index, Commsec, Sharesight and 2iQ also collate them. AlgoKing's Insider Activity Tracker aggregates this data for you.

No. Insider buying is a positive signal but should be combined with fundamental analysis. Use it as a filter or confirmation, not the sole criterion. Verify the quality of the transaction (on-market vs ESS vesting, size, insider seniority).

No. Insiders sell for many benign reasons: diversification, personal expenses, CGT timing, and ESS vesting. What is concerning is cluster selling (multiple insiders), consistent selling at highs, or selling just before bad news.

Under the company's trading policy (ASX Listing Rule 12.12), insiders generally cannot trade during closed/blackout periods - typically from the end of the half-year or full-year until shortly after results - unless they obtain prior written clearance.

Check when you receive alerts for significant activity, do a monthly review of your holdings, and check before making new investments. AlgoKing automates this with real-time alerts.

Look for: on-market purchases (vs ESS vesting), senior insiders (MD/CEO/CFO vs junior executives), size relative to holding, and whether they hold or immediately sell. Vesting-and-hold is more meaningful than vesting-and-sell.

Generally: <10% is low risk, 10-25% moderate, 25-50% high, >50% critical. Context matters - compare to sector norms and the insider's ability to service the debt. A rising trend is more concerning than a stable level.

Aggregate insider activity across all stocks in each sector. Sectors with net insider buying may outperform. It can be a leading indicator - insiders collectively see sector trends before they are obvious.

Research suggests 3-12 months. There is some immediate effect, but most outperformance accumulates over 6+ months. It is a medium-term signal, not for day trading.

A pre-arranged block sell-down or sell-down into a placement is often planned and announced, and is less concerning than unexpected on-market selling. Context matters - check the stated reason.

Calculate net insider buying (weighted by seniority), normalise cross-sectionally and against the stock's own history, apply decay for older transactions, and combine with cluster and margin-loan adjustments into a composite score. Backtest long top quintile, short bottom.

Strong features include transaction size relative to holding, insider type/seniority, a cluster indicator, time since the last transaction, plus stock features (momentum, valuation, volatility) and contextual features (results proximity, market regime).

Early warning signs: rising secured exposure, multiple KMP departures, consistent insider selling at highs, delayed disclosures, and an increase in related-party transactions. Combine into a governance score and monitor for deterioration.

Limitations include the disclosure lag (up to 5 business days for directors; 2 for substantial holders), thinner coverage for small caps, mandatory personal-trade disclosure being limited to directors, ESS noise, and the fact that insiders can be wrong.

Treat it as a separate factor with low correlation to traditional factors. Combine with value, momentum and quality. Weight based on backtest performance. Use it as an overlay or tilt rather than the primary factor, and monitor for crowding.
