Deterministic analysis from filing data
The latest institutional read on LPX
The latest 13F cycle gives LPX a fresh ownership snapshot. 1 active managers reported $412.1M in aggregate value. Berkshire Hathaway is the largest tracked holder. The sample is too small for a broad concentration reading.
Position changes show where the quarter differed from the prior filing. Berkshire Hathaway made the largest measured share-count move at 0.0%. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
The trailing history shows whether the manager sample is expanding or contracting. Holder count remains near the trailing average of 1.0. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
Comparable ownership pages show whether LPX's pattern is unusual. Related ownership pages include AAPL, AXP, KO. Return to LPX stock research for financial statements, earnings, and company risks.
