This page is designed to answer the real investor question behind a 13F filing: how meaningful was DUPONT CAPITAL MANAGEMENT CORP's position in LYNTRIS INC, and how did that conviction change over time? You can read the holding window, peak weight, latest reported size, disclosure timing, and quarter-by-quarter changes without piecing the story together from raw SEC rows.
LYNX was reported at 88.01% of portfolio in the most recent visible filing.
Peak weight helps separate a token disclosure from a real conviction holding the fund genuinely cared about.
Longer holding windows often tell a very different story from short-lived tactical trades or one-quarter experiments.
Knowing that a fund owned a stock is useful. Knowing whether it was a 0.20% placeholder or a true high-conviction position is where the signal actually starts.
These are the practical questions this page is built to answer before you even open the full history table.
