Overview

This skill reviews investment portfolios to identify risk exposures, diversification gaps, excessive fees, and tax optimization opportunities. It delivers clear asset-allocation recommendations, rebalancing plans, and tax-loss harvesting suggestions tailored to investor goals and constraints. Outputs are practical, copy-ready, and include brief disclaimers on investment advice.

How this skill works

The analyzer ingests portfolio holdings, positions, transaction history, and investor profile (horizon, risk tolerance, tax status). It calculates risk metrics (volatility, beta, concentration), evaluates diversification across asset classes and sectors, and flags high-fee components. It then produces target allocation scenarios, rebalancing trades, and candidate tax-loss harvesting opportunities, plus estimated cost/benefit. Recommendations include implementation notes and a short risk disclaimer.

When to use it

Before rebalancing or after a major market move
When assessing fees and performance drag
At year-end for tax-loss harvesting planning
When consolidating multiple accounts or advisors
When forming or updating an investment policy statement

Best practices

Provide complete holding details and recent cost basis for accurate tax-loss analysis
Share investment objectives, liquidity needs, and time horizon upfront
Accept concrete, prioritized actions (trade-size and target dates) rather than vague goals
Run both current-state and target-state scenarios to quantify trade impact
Include estimated costs (tax, trading, bid/ask) when recommending trades

Example use cases

Convert a concentrated stock position into a diversified ETF ladder with stepwise rebalancing and hedging options
Produce a year-end tax-loss harvesting list with realized loss estimates and wash-sale controls
Evaluate portfolio fees and recommend lower-cost fund replacements with transition cost analysis
Build a target allocation for a 10-year goal with monthly rebalancing thresholds and glide-path options

FAQ

Is this personalized financial advice?

No. Recommendations are analytical and actionable but should be reviewed with a licensed financial advisor or tax professional before implementation.

What inputs give the best results?

Provide holdings with quantities, cost basis, account type (taxable/IRA/401k), recent trades, and concise investor goals for precise recommendations.
