Lam Research Corporation
Could not find a ticker for this position, may be a filing error
A maker of the machinery that fabricates silicon chips—the etch, deposition, and cleaning tools used by manufacturers like Samsung, SK hynix, Micron, and TSMC to build memory and logic semiconductors. Founded in 1980 by Dr. David K. Lam in Santa Clara, California, the company's name isn't an acronym despite jokes about "Let's All Move"—it simply honors its founder's surname. Its product families include Kiyo and Flex etch tools and ALTUS and VECTOR deposition systems.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -863.7K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
