The Private Portfolio System

Six services on the baize table

JIGSAW INVEST is the operating desk of JIGSAW INVESTMENTS LLC. Our work is not portfolio marketing and it is not trading theatre. It is a system of research, administration, and record-keeping built for holdings we expect to keep across years and across cycles. Every service below exists to make long-horizon ownership quieter, safer, and easier to reason about.

Portfolio Research Briefs

The shared instrument of the desk is the written brief. Before any holding is added, changed, or held at rest, the desk assembles a research brief that puts the case on paper. The brief weighs new earnings evidence against the original reason to own, checks the thesis against the latest competitive and regulatory facts, and reaches a plain conclusion without hand-waving.

A good brief does not decorate a decision that was already made. It lays out the bullish case and the bearish case with equal honesty, marks the key assumptions that would change the verdict, and ends with one of three words: hold, trim, or top up. Because the brief is written down and dated, the next review in a later year can measure how well the reasoning aged. We refuse the habit of revising history in the memory.

Briefs are issued on a fixed cycle for ongoing holdings and on request when a principal surfaces a new idea worth study. Every brief ends up numbered and filed so that the whole portfolio has a written life story rather than a scattered collection of half-remembered choices.

Holding Administration

A position does not end when the ticket fills. From that moment a backlog of administrative obligations begins: dividend and interest entitlements, corporate actions, class and series changes, tax reporting events, standing instructions and settlement confirmations. Holding administration keeps that pile organized so nothing slips past unrecorded.

The desk tracks each holding through its whole lifecycle, maintaining a clean ledger of every event that touches it. When a company announces a split, a special dividend, a redemption, or a class change, the record is updated and the principals are told once, clearly, what it means for the position. There is no guessing at tax time and no surprise at statement time.

Most importantly, good administration keeps the noise away from the decisions. Because the mechanics are handled quietly and completely, the principals can spend their attention on the thesis rather than on chasing papers. That separation is the whole point of a proper dealing room.

Position Rebalancing Plans

Long-horizon portfolios drift. One holding grows until it dominates the whole, another shrinks into an afterthought, and the intended balance slowly fades without anyone intending it. Rebalancing is how we bring the portfolio back toward its target shape, but it must be done without reaction to the daily tape.

We write rebalancing as a set-piece plan rather than a series of impulses. Each plan names the position to adjust, the target weight, the drift threshold that triggers action, the size of the step to restore balance, and the scheduled review date. The plan sits on the baize until its trigger is touched, at which point the step is executed in a controlled way.

This discipline converts a source of anxiety into an item of plumbing. The portfolio is measured on the same cadence, compared against policy, and corrected in deliberate, modest steps. Principals always know where the portfolio stands against policy and what would cause us to act.

Cash-Flow Scheduling

Money enters and leaves a portfolio on dates that drift across months and years. Dividends and coupons land on a schedule, capital calls ask when they ask, and reinvestment windows open without warning. A desk that cannot see its cash calendar can spend the same dollar twice or let capital lie idle past its moment.

Cash-flow scheduling builds a forward calendar for the entire portfolio. Every expected receipt is dated, every obligation is dated, and the running balance is shown as it will develop across the coming quarters. When a call arrives early or a dividend is missed, the calendar is updated and the effect on the plan is stated plainly.

The result is a portfolio that never surprises itself with a shortfall and never leaves cash parked longer than policy allows. Scheduling turns the treasury side of long ownership into the most boring and the most dependable part of the desk, which is exactly what we want it to be.

Risk Review Panels

Every portfolio talks about risk; very few actually slow down to measure it. A risk review panel is a standing appointment at which the whole position inventory is opened on the baize and asked the uncomfortable questions: how concentrated are we in one name, one sector, or one idea, and what would happen if our favorite reason stopped being true.

The panel reviews concentration against policy, checks realized and unrealized drawdown patterns, and re-tests the resilience of each thesis to its own failure. The tone is cool rather than alarmed. Panels exist to catch drift before it becomes damage, not to manufacture fear out of a healthy portfolio.

Every panel writes its findings into the record with plain recommendations attached. Nothing is hidden and nothing is smoothed over. A principal can read the latest panel page and know within minutes how the desk rates the current risk posture and what would make us uneasy enough to act.

Records and Statement Archiving

An unarchived portfolio is only as trustworthy as its best memory. Every brief, every decision, every confirmation and every statement is numbered, dated and filed in the drawer so that the whole history of the portfolio can be reconstructed at any moment without relying on anyone remembering it correctly.

Records are kept in a form that resists quiet loss: statements are reconciled against the ledger, briefs are cross-referenced to the positions they cover, and decisions are attached to the instructions they produced. The archive reads like a proper house record rather than a shoebox of unnumbered papers.

When a principal asks what was decided three years ago, or how a position came to look the way it does, the answer comes from the drawer and not from a conversation. Archiving is the quiet discipline that makes decades of patient ownership possible, because only what is written down can be owned with confidence.
