AdvisorShares Insider Advantage ETF (SURE)
What is insider buying telling you?
When a CEO or board member buys shares of their own company, it is one of the few moments when someone with material, non-public knowledge is forced to bet their own capital. Insider Advantage ETF (ticker SURE, issued by AdvisorShares) tracks a simple thesis: companies where insiders are net buyers — where officers, directors, and substantial shareholders have recently stepped up to buy — are worth noticing. The fund holds a diversified portfolio of US-listed companies selected and weighted by insider buying activity.
The bet is behavioural and informational at once. An insider who buys is either confident the stock is cheap, or concerned the market is punishing the company unfairly, or both. They have read the full strategy memo, know what is coming next quarter, and see the balance sheet. If they are buying, maybe the market is wrong. The opposite is also true: when insiders sell heavily, it has historically preceded weakness. Insider buying is not a perfect signal — insiders sometimes sell for reasons unrelated to valuation, and they can be wrong — but it is more reliable than pure retail sentiment, and it has been shown across decades of data to correlate with subsequent outperformance.
How does SURE select and weight its holdings?
The fund uses an insider-buying signal to screen and rank companies. The exact methodology — the threshold for what counts as material buying, the lookback period, how the fund weights stocks — is set out in the prospectus and fact sheet. Broadly, the process identifies companies where recent insider purchases exceed a threshold as a percentage of the company’s float (or other measures of significance), then holds a portfolio of those names, often with larger positions for the companies showing the heaviest insider demand. The portfolio is typically held for a defined period — say, a rolling quarter or year — and rebalanced as new insider-buying signals emerge.
This approach naturally tilts the fund toward smaller and mid-cap stocks, because insiders at larger companies tend to have fewer opportunities to make purchases that are material relative to the float, and because more-liquid, more-heavily-traded stocks have higher turnover in ownership. The fund is thus unlikely to be heavy in mega-cap names, even if insiders at those companies are buying.
What are the real risks?
Insiders can be wrong. A CEO who buys can still preside over a company that declines. Insider buying can also reflect a desperate effort to stabilize a stock after bad news — buying the dip at what turns out to be a value trap. The fund also carries execution risk: if insider buying is a mild signal that takes quarters or years to play out, the fund’s frequent rebalancing (chasing new buying signals) can generate tax drag and turnover costs that eat into returns. And insider buying is public information; if it is useful, the market should eventually price it in, making the signal weaker for new investors entering after the insider already bought. Finally, insider purchases represent conviction about the near-term outlook, but are not a proxy for long-term business quality; a fund weighted purely by insider buying can end up holding a collection of battered stocks that insiders like at present prices but that never improve.
How to research SURE
Start with the fund’s prospectus and fact sheet, available from AdvisorShares. These lay out the selection criteria, the rebalancing schedule, and the holdings. The underlying index it tracks may be available through the index provider. Look at the fund’s recent holdings and their subsequent performance — did the insider-buying signal work? Track the fund’s return versus a broad market benchmark over different time periods to see whether the signal has held up. You can also cross-reference the holdings against SEC filings (on EDGAR, searchable by CIK) to verify that insiders are indeed buying at the prices and volumes the methodology claims.
