You have, at this point, a workshop full of excellent tools. You can spread a filing by hand, run a quality-of-earnings screen, build a DCF and reverse it, grade a moat four ways, run a sector playbook, read the macro weather, size a bet with fractional…

Learning objectives

By the end you can:

  1. Assemble the full investment loop: name its nine stages in order, state which module built each and what each hands to the next, and explain why running them as a closed, feeding loop (rather than as isolated skills) is what makes a process compound over decades.
  2. Operate the decision journal as the spine of the process: write the expanded investment-decision entry (thesis, disconfirming evidence, base rate, numeric confidence, kill criteria, sizing and portfolio-fit rationale, monitoring metrics, review date) before the outcome, never edit it after, and explain precisely why pre-commitment defeats hindsight bias.
  3. Write a quarterly review letter: produce the format (positions, decisions, mistakes, calibration, what changed my mind), explain every holding and every buy/sell as if to a demanding investor, and articulate why the act of writing forces a clarity that thinking alone does not (the Buffett/Marks practice).
  4. Compute and read your calibration: bucket your probabilistic predictions, plot the reliability curve, diagnose whether and where you are over- or under-confident (by confidence level and by domain), compute a Brier score, and convert the diagnosis into specific corrections (haircut confidence, widen ranges, downsize, avoid a domain).
  5. Separate skill from luck with a process scorecard: score a decision on its process on a fixed rubric independent of its outcome, place any resolved decision in the decision-quality × outcome-quality grid, explain "resulting" and the paradox of skill, and run two scoreboards (process and P&L) knowing which one to optimize.
  6. State and enforce survival-first discipline: explain why avoiding ruin is the precondition for compounding (ergodicity), enumerate the forms of forced liquidation (margin, ALM mismatch, redemptions, derivatives, illiquidity-plus-a-cash-need), and specify the leverage and position-limit rules that guarantee no market move can make you sell at a time not of your choosing.
  7. Run a drawdown behaviorally, by protocol: walk the exact steps your process prescribes when a position or the whole portfolio is deep in a drawdown, so that a calm, pre-committed past self makes the hold/add/sell decision rather than a panicked present one.
  8. Produce your complete written investment process document: the operating manual covering philosophy, circle, sourcing criteria, analysis workflow, checklist, sizing and portfolio rules, sell rules, review cadence, and anti-goals. Then run one full simulator season scored on process, completing the M10 milestone.

Prerequisites & connections

Builds on. This module is an assembly, so it depends on nearly everything, but four modules are load-bearing. M9.01 (risk and position sizing): fractional Kelly, conviction-versus-downside, hidden correlation, and the ruin constraint are the sizing and survival stages of the loop, and they become standing rules here. M9.02 (portfolio construction): hurdles and opportunity cost, cash as a position, the concentration policy, and correlation are the portfolio-fit stage. M9.03 (selling and mistakes): the five legitimate sell reasons, the error of selling compounders early (Freeman-Shor), and your mistake taxonomy are the sell and part of the review stages. M8.01–M8.05: the timed teardown and the 2–3 day deep dive are the analysis stage; the one-page thesis you write there is the raw material of the journal entry here. Beneath those: M6.05 installed the checklist, the decision journal, and calibration/Brier as concepts and produced your Checklist v1, and those components now get wired into a running loop while the calibration data M6.05 began collecting finally gets graded; M6.03 supplies the decision science the whole loop enforces (process over outcome, expected value, base rates, Bayesian updating, ergodicity/ruin); M0.04 installed the original eight-field journal template, which §4.2 expands into the full investment-decision schema; and M3.05 (the reverse DCF, "what is priced in?") is the valuation test every journal entry must clear.

Feeds forward. Phase 10 is nothing but this loop, run for real and unaided: M10.01 and M10.02 are two full independent deep dives on never-studied companies (US, then India) that execute this exact process end to end and produce institutional-grade theses; M10.04 sets up the lifelong regimen (a public track record, a paper portfolio, the staying-current stack), which is this loop turning forever, and runs the final competency audit against Section 1 of the master map, where C9 is certified largely here. Your written process document becomes the standing operating manual for all of Phase 10 and the decades after it; your calibration record and process scorecard become the objective, luck-proof evidence that your judgment is actually improving, which over short horizons is the only kind there is.
