AAPL Concentrated Stock Exit | FIFO vs Prepared Lots
PROOF LOG #018
AAPL Concentrated Stock Exit | FIFO vs Prepared Lots
Prepared exit. Reviewable path.
A concentrated AAPL exit can consume the 2016 low-basis lot if FIFO controls the sale.
FDL carries the CPA-prepared Target Lot IDs through the run.
A concentrated exit is not just one sale.
The CPA prepared two AAPL exit lots before the run.
FDL carried those Target Lot IDs into Dashboard, Tax Report, and Audit Trail.
The result: $3,259,500 of Specific ID differential made reviewable.
Proof Summary
Problem: A concentrated AAPL exit can hit an old low-basis lot if FIFO controls the sale.
Prepared input: FDL carries the CPA-prepared Target Lot IDs for two selected AAPL exit lots before the run.
Board result: Tax Alpha Dashboard shows $3,259,500 of Specific ID differential, Tax Report shows two selected tax rows, and Audit Trail keeps the 2016 low-basis lot open.
Boundary: FDL does not choose lots or provide lot-picking advice. It verifies prepared, in-scope selected-lot records through deterministic outputs.
WATCH THE RECONSTRUCTION
Watch a concentrated AAPL exit become a reviewable selected-lot path.
- FIFO would have consumed 15,000 sh from the 2016 low-basis AAPL lot
- the CPA prepared two exit lots before the run
- Tax Alpha Dashboard shows $3,259,500 of Specific ID differential
- Tax Report shows 2 selected tax rows and $547,500 total gain
- Audit Trail shows the 2016 low-basis lot remains open with 60,000 sh
EXECUTIVE PROOF
FIFO Default
- concentrated exit can hit the old low-basis lot
- FIFO baseline would consume 15,000 sh from the 2016 AAPL lot
- the old lot carries a low $26.34 unit basis
- the reviewer must prove what left and what stayed
FDL Registry of Truth™
- prepared Target Lot IDs flow through the run
- Tax Alpha Dashboard surfaces $3,259,500 of Specific ID differential
- Tax Report shows 2 selected tax rows and $547,500 total gain
- Audit Trail preserves the old low-basis exposure as still open
PHASE 1 — THE CONCENTRATED EXIT RISK
AAPL was held across multiple lots.
If FIFO controls the sale, the old low-basis lot leaves first.
In this case, FIFO would have consumed 15,000 sh from the 2016 lot.
A concentrated exit can hit the old lot.
PHASE 2 — THE PREPARED EXIT LOTS
The CPA prepared two exit lots before the run.
10,000 sh were mapped to the October 2025 AAPL lot.
5,000 sh were mapped to the July 2024 AAPL lot.
This is prepared lot execution, not retroactive lot picking.
PHASE 3 — THE REVIEWABLE EXIT PATH
Tax Alpha Dashboard shows the $3,259,500 FIFO-vs-selected-lot differential.
Tax Report shows 2 selected tax rows and $547,500 total gain.
Audit Trail shows the 2016 low-basis lot remains open with 60,000 sh.
FDL proves what left, what stayed, and what result hit the file.
FORENSIC EVIDENCE
What must remain intact
- 2025 selected exit lotThe October 2025 AAPL lot must be consumed by the 10,000-share sale row.
- 2024 selected exit lotThe July 2024 AAPL lot must be partially consumed by the 5,000-share sale row.
- 2016 legacy lotThe low-basis 60,000-share lot must remain open and untouched.
- FIFO baseline comparisonThe default path must remain visible as a comparison, not as a recommendation.
What FDL makes legible
- Tax Alpha DashboardShows $3,259,500 of Specific ID differential.
- Tax ReportShows 10,000 sh SHORT and 5,000 sh LONG as separate selected tax rows.
- Audit TrailShows the 2025 lot closed, the 2024 lot partially open, and the 2016 lot untouched.
- TransactionsCaptures two SELL rows mapped to two CPA-prepared Target Lot IDs.
This is the point of the white-box architecture:
prepared exit lots, board value, filing result, and remaining exposure stay separate and reviewable.
WHY THIS CASE MATTERS
For UHNW taxable accounts, concentrated exits are not just proceeds events.
They are lot-level proof problems.
The question is not only what was sold.
The question is whether the reviewer can prove what left, what stayed, and what result hit the file.
WHAT FDL IS SHOWING HERE
FDL is not a recommendation engine.
FDL does not choose the lots.
FDL carries a prepared concentrated-stock exit path through Tax Alpha Dashboard, Tax Report, and Audit Trail.
The value is reviewable prepared-exit execution.
