Insider Radar

Filings worth a closer look.

Research signals from unusual SEC insider purchases.

Insider Radar is a set of research candidates identified from public SEC Form 4 filings using transaction characteristics, insider history, ownership changes, and other documented factors. These are transactions surfaced by the research model for further investigation.

Each one sets out what was reported, who reported it, which factors the model observed, and what could undermine it — so the evidence can be weighed rather than taken on trust.

InsiderScanner identifies unusual insider purchases for research. Ratings, scenarios and historical statistics are model outputs, not investment recommendations.

Sample research case. One case is shown in full so the format can be judged before signing up. The rest of the open basket opens as soon as you have an account, at no cost.

1 open case. Ordered as published by the model, not ranked by expected return.

A HIGH evidence

Swank Jerry V (CFO & Treasurer, See Remarks) reported an open-market purchase of $958,150 on 2026-10-23.

Factors observed 5 of 5

Strong evidence
✓ C-suite executive Title names CEO, CFO, COO, CTO, President, Chair or Chief Filing says: CFO & Treasurer, See Remarks
✓ High conviction Conviction tag equals HIGH Filing says: HIGH
✓ Oversold setup 14-day RSI at or below 35 Filing says: RSI 22.2
✓ Near 52-week low Price in the bottom 35% of its 52-week range Filing says: 7% of 52-week range
✓ Sizeable relative purchase Purchase worth at least 0.10% of market capitalisation Filing says: $958,150 · 29.4 bps of market cap

What this is, and is not. Each row is one test with its exact threshold and the value the filing carried, so the result can be checked rather than taken on trust. The model publishes a letter tier, not a point total — there is no score out of anything here because it does not produce one. These are observations about a filing, not a forecast of what the share price will do.

Independently corroborated The market-wide Form 4 stream shows 3 insiders buying at $NXG, 1 of them C-suite, totalling $525,575 — a cluster.

Why it qualified

CFO & Treasurer Swank put in ~$958K on Oct 23, a second insider alongside him, and ΔOwn is enormous at +1216% — essentially a brand-new material stake, which is real conviction. Setup is a deep oversold flush: price 3.8% off the 52w low, RSI 22, trading ~18% below MA50 after a drawdown, with the insider buying right at current price (+1% above). Clean net flow; note this is a leveraged closed-end infrastructure income fund paying ~100% return-of-capital distributions, so it's an income vehicle, not an operating company.

What could undermine this

Closed-end fund with 100% return-of-capital distributions and recent rights offering (dilution mechanism); sector lagging SPY by ~5.6%; single-source signal.
