Every open-market purchase and sale reported by DLHC officers, directors and 10%+ beneficial owners on SEC Form 4, which must be filed within two business days of the transaction. Sales often reflect scheduled 10b5-1 plans or tax withholding rather than a directional view, so read counts alongside the size and the filer.

DLHC Insider Trading FAQ

Who are the insiders at DLHC?

9 officers, directors and 10%+ beneficial owners currently report holdings in DLHC via SEC Form 4.

Are DLHC insiders buying or selling?

Across the 50 most recent Form 4 filings for DLHC, 41 were open-market purchases (code P) and 0 were sales (code S). Sales frequently reflect scheduled 10b5-1 plans or tax withholding rather than a view on the stock.

How current is DLHC insider data?

Form 4 must be filed within two business days of the transaction, so this is close to real time. The most recent DLHC filing is dated 2026-10-05.

How to read Form 4 activity

Form 4 reports a change in beneficial ownership by an officer, director or 10%+ holder, and must be filed within two business days of the transaction — so this is close to real time, unlike the 45-day-lagged 13F institutional data.

Transaction codes matter more than the raw buy/sell count. Code P is an open-market purchase — an insider choosing to buy with their own money, which is the signal most research treats as informative. Code S is a sale, but sales are frequently pre-scheduled under a 10b5-1 plan or cover tax withholding on vesting equity, so a run of sales often says nothing directional. Codes A and M are grants and option exercises rather than open-market decisions.
