Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Bel Fuse Inc are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 294 Forms 3, 4 and 5 on record for Bel Fuse Inc (SEC CIK 729580), filed from Sep 10, 1998 to Oct 7, 2026; 29 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages. 1 older filing exists only on paper and could not be read.
Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.
Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
