Step 1
Audit thesis drift across holdings
Check whether each position still fits its original thesis and risk case. Thesis drift is a common source of hidden portfolio fragility.

Monthly Portfolio Review Template for Decision Discipline
A monthly portfolio review template to detect thesis drift, concentration risk, and rule violations—then rebalance with evidence instead of emotion.
A monthly portfolio review is where long-term discipline is maintained: small process drift gets caught before it becomes a big drawdown. This template helps you audit thesis changes, track concentration and correlation risk, and score rule adherence (checklist completion, reactive trades, sizing violations). It forces one actionable output each month: rebalance, reduce risk, or reaffirm the thesis with updated evidence. If thesis-critical information appears mid-month, run an event-driven review instead of waiting. Use it alongside your journal and post-trade reviews so decisions stay auditable, not emotional.

Step 2
Reassess concentration and correlation risk
Review exposure overlap by sector, factor, and narrative dependency. Diversification quality matters more than position count.
Step 3
Score execution consistency for the month
Track checklist completion, rule violations, and reactive trades. This creates an objective behavior score over time.
Framework
1) Audit thesis drift across holdings
Check whether each position still fits its original thesis and risk case. Thesis drift is a common source of hidden portfolio fragility.
2) Reassess concentration and correlation risk
Review exposure overlap by sector, factor, and narrative dependency. Diversification quality matters more than position count.
3) Score execution consistency for the month
Track checklist completion, rule violations, and reactive trades. This creates an objective behavior score over time.
4) Convert findings into one explicit action
End every review with a single decision per holding: reaffirm, reduce, exit, or re-underwrite. Attach a threshold (what evidence would change your mind next month) so the review outputs are actionable, not just commentary.

FAQ
What should be mandatory in every monthly portfolio review?
At minimum: a one-sentence thesis status update for each holding, a concentration/correlation check, a rule-adherence score (what you followed vs violated), and one explicit action for next month.
Is monthly review enough in volatile markets?
Monthly is a baseline cadence, not a rule. If thesis-critical information lands mid-month (earnings, regulation, liquidity shock, management change), run an event-driven review so you are not “waiting for the calendar.”
How do I avoid turning monthly reviews into overtrading?
Decide thresholds in advance: what level of weight drift, valuation band breach, or thesis evidence change triggers action. If nothing crosses your threshold, the correct output is often “no change.”
Should I rebalance back to target weights every month?
Not automatically. Use rebalancing bands (and consider taxes and trading costs) so you are correcting meaningful drift, not reacting to noise.
How do I score execution consistency without fooling myself?
Score behaviors, not outcomes: checklist completion, sizing discipline, impulsive adds, and rule violations. A good month can still be a low-quality month if you broke rules; a bad month can be a high-quality month if the process was sound.

Run this month’s review once, log one process score, and carry forward one improvement rule.
