Methodology & FAQ
How This Position History Is Sourced
Each row is one SEC Form 13F-HR filing disclosing this position. Share count, market value, and reported quarter are taken verbatim from the filing; portfolio weight is recomputed against the same filing's total reported equity book. Implied price-per-share is market value divided by shares — a quarter-end mark, not the manager's cost basis. See the full methodology document for the normalization rules.
When did PECONIC PARTNERS LLC first disclose a FSLR position in 13F-HR filings?
PECONIC PARTNERS LLC first reported FIRST SOLAR INC (FSLR) on its 13F-HR filing for the period ending 2017-06-30 (Q2 2017). The position has appeared on 36 reported quarters within Pactolio's tracked window.
What was PECONIC PARTNERS LLC's most recent quarter-over-quarter share-count change in FSLR?
Between Q4 2025 and Q1 2026, PECONIC PARTNERS LLC added 100,000 shares of FSLR (+33.9%), bringing the total reported position to 395,000 shares at a market value of $77.9M.
Does the implied price-per-share represent PECONIC PARTNERS LLC's cost basis in FSLR?
No. The implied price-per-share column is the 13F-HR reported market value divided by reported share count on the filing date (end of quarter). It is a quarter-end mark, not a cost basis or transaction price. Use it as a sanity check on the value column, not as an indicator of the manager's entry or exit price.
