This page is designed to answer the real investor question behind a 13F filing: how meaningful was INVESCO SENIOR SECURED MANAGEMENT INC /ADV's position in Seadrill Limited (fka Aquadrill), 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.
SDRL was reported at 18.77% 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.
