Donald Arthur Seibel Jr., listed as board member, appears in our data through filings on ACNB Corp shares, published by SEC (Form 4). In total, 56 filings cover trades dated from 15 September 2017 to 15 September 2026.

Both buying and selling appear: 6 purchases worth €10k, against 15 sales worth €1.6M. Taken together, the sales exceed the purchases by €1.6M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 35 share grants. So far in 2026, the count stands at no purchases and 1 sale.

The median purchase comes to €1,899. On 6 out of 6 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster.

Most recently, on 17 September 2026, the filings show a share grant worth €12k in ACNB Corp. The clock since the last published purchase (20 September 2018) now reads 2,955 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
