Portfolio Toolbox

What is Portfolio Toolbox? What can it do for you?

What is the "Portfolio Toolbox"?

Portfolio Toolbox is a professional-grade portfolio analysis suite with three core tools:

• Builder: AI builds your optimal portfolio based on your factor preferences
• Diagnosis: Input your existing holdings for deep factor exposure and sector analysis
• Optimization: Given a set of stocks/ETFs, calculate optimal weight allocation using Modern Portfolio Theory

Three tools covering the full portfolio lifecycle — from construction, to analysis, to optimization.

Three Tools at a Glance

Core Value

• Professional quantitative analysis: Institutional-grade factor analysis, risk models, and portfolio optimization algorithms
• 25,000+ tickers covered: Stocks, ETFs, mutual funds across major global markets
• No coding required: Visual interface — drag and slide your way to professional analysis
• Full workflow coverage: From stock picking → diagnosis → rebalancing optimization — one set of tools does it all
• Save history: All analysis results can be saved, reviewed, and compared anytime

What Can You Do with Portfolio Toolbox?

• ✅ Build new portfolios: Tell AI your value/growth/quality preferences, auto-generate a basket of stocks
• ✅ Analyze existing holdings: Upload or manually enter your holdings to see true factor exposure
• ✅ Optimize weights: Give it a few stocks, get the highest Sharpe ratio allocation
• ✅ Risk diagnosis: See if your portfolio is over-concentrated in a sector or factor
• ✅ Performance comparison: Your portfolio vs. benchmark index — who has better risk/return?
• ✅ Manage multiple portfolios: Save multiple portfolio schemes, compare different strategies

Note: Portfolio Toolbox is a quantitative analysis tool, not investment advice. Analysis results are for research reference only — make decisions based on your own judgment and risk tolerance.

   • Factor return attribution chart

💡 Want to try it quickly? Click "Load Sample Portfolio" to load an example portfolio.

Step 3: Use Optimization to Fine-Tune Weights

Once you have a set of stocks you like, open Optimization:

1. Enter 2+ stocks/ETFs/funds
2. Choose an optimization strategy (Max Sharpe / Min Volatility / Risk Parity / HRP)
3. Set weight constraints (min/max)
4. Choose a benchmark index
5. Click Run Optimization → get the optimal weight scheme

Dashboard Overview

The first page you see when opening Portfolio Toolbox.

Quick Start Guide

A guide card at the very top of the page — 3 steps to get started:

1. Build Your Portfolio (🔧) — Click to open the Builder help modal, learn factor definitions
2. Analyze Performance (🔍) — Open the Diagnosis help modal, learn how to input and interpret
3. Optimize Allocation (📊) — Open the Optimization help modal, understand optimization strategies

On the right side there's also an external help link that jumps to Kavout Academy's Portfolio Toolbox tutorial page.

💡 Each tool page also has its own Help button — you can open the corresponding help modal anytime for definitions and instructions.

Stats Navigation Cards (3)

Each card shows the count + most recent record. Click to jump directly to the corresponding tool.

Saved Tab

Shows all saved portfolios/diagnoses/optimizations:

• List format, paginated
• Each item shows: name, type (Builder/Diagnosis/Optimization), creation date
• Actions: View Results, Delete

Recent Activity Tab

Shows all analyses run in the last 7 days:

• Sorted by time (newest first)
• Click any item → auto-jumps to the corresponding tool page and restores the parameters and results from that time
• Data is passed via localStorage, valid for 5 minutes

Builder (Portfolio Builder)

Feature Positioning

Intelligently screens and weights stocks from the entire market based on your factor preferences, building a customized investment portfolio.

Configuration (Step 1)

① Region

② Market Cap

③ Sector

Default: All Sectors. 11 sectors available for individual filtering:

• Basic Materials / Consumer Cyclical / Financial Services / Real Estate

④ Factor Weights

5 sliders, each 0-100, all default 50 (Neutral):

Three slider labels:

• Underweight: 0-40, lower factor influence
• Neutral: 50, default balanced level
• Overweight: 60-100, higher factor influence

💡 Sliders are independent — they don't have to sum to 100. The higher you set a factor, the more weight it has in stock selection.

A Reset All to Default button at the bottom restores everything to 50.

⑤ Number of Stocks

10 / 20 / 30 / 50 / 100 options.

• Top progress bar shows total weight in real-time:
  • 🟢 Green: exactly 100%
  • 🟠 Orange: over 100%
  • 🔵 Blue: under 100%
• Quick action buttons:

• After upload you enter the same editing interface as manual entry — you can continue adding/removing

Quick Try

• Load Sample Portfolio: one-click loads AAPL 25.5% / MSFT 22.3% / SPY 18.7% / QQQ 15.2% / VTI 18.3%

Run Diagnosis

• Run Diagnosis → start analysis
• If any stocks have insufficient data, it's noted at the top of results (with excluded ticker list)

Results (Step 2)

Each stock shows 7 factor scores (0-100, color-coded):

🎨 Color rules (dark blue → light gray, higher score = darker color):

• ≥ 50: Dark blue (strong factor exposure)
• 20-50: Indigo (moderate)
• 1-20: Slate gray (weaker)
• < 1: Light gray (very weak)

Instantly see each stock's strength across factors.

Optimization (Portfolio Optimizer)

Feature Positioning

Given a set of stocks/ETFs/funds, calculate optimal weight allocation based on Modern Portfolio Theory (MPT) to maximize the risk-return ratio.

Configuration (Step 1)

① Portfolio Securities

• Search box for ticker entry (supports stocks/ETFs/mutual funds, same autocomplete as Diagnosis)
• Added securities shown as tags; click × to remove
• At least 2 securities required to run optimization
• Load Sample: one-click loads AAPL / MSFT / SPY / QQQ / VFIAX

② Optimization Strategy

③ Weight Constraints

• Min Weight: 0 / 0.5 / 1 / 2 / 3 / 5 %
• Max Weight: 5 / 10 / 15 / 20 / 25 / 30 / 40 / 50 %

For example, setting Max Weight = 20% ensures no single asset exceeds 20% of the portfolio, avoiding over-concentration.

④ Risk Measure

Benchmark index for performance comparison:

• SPY (S&P 500)
• IWB (Russell 1000)
• IWM (Russell 2000)
• VTI (Total Market)

FAQ

What's the difference between Builder, Diagnosis, and Optimization? When do I use each?

Simple way to think about it:

• Builder = "What should I buy?" (recommends stocks + weights for you)
• Diagnosis = "How are my current holdings doing?" (analyzes your existing portfolio's factor exposure)
• Optimization = "I have these stocks, what's the best weight allocation?" (calculates optimal ratios for a given set of stocks)

Typical workflow: Builder picks stocks → Diagnosis analyzes → Optimization adjusts weights.

How do Builder's factor weights work?

The five factors (Quality/Value/Momentum/Growth/Low Volatility) each score independently 0-100.

• Higher slider = more weight for that factor in stock selection
• They're not mutually exclusive, and don't need to sum to 100
• The algorithm combines all factor weighted scores to pick the top N ranked stocks
• Think of each slider as "my preference level for this factor"

What assets does Diagnosis support?

Supports stocks, ETFs, and mutual funds. Any ticker with data in the system works. If a ticker has insufficient data, it's automatically excluded and noted at the top.

What's the minimum number of stocks needed for Optimization?

At least 2 assets are required to run optimization. 3-20 works best — too few and there's not much to optimize; too many and weights get too spread out.

What is the Sharpe Ratio?

Sharpe Ratio = (portfolio return - risk-free rate) / portfolio volatility. Measures "how much excess return you get per unit of risk."

• Higher is better — generally >1 is good, >1.5 is excellent
• This metric appears in both Builder and Optimization results
• The Max Sharpe strategy finds the portfolio with the highest Sharpe ratio among all feasible combinations

What is Risk Parity?

Traditional equal weight means "same dollar amount in each stock." Risk parity means "each stock contributes the same amount of risk to the portfolio."

• More volatile assets automatically get lower weight; less volatile get higher weight
• The goal is equal risk contribution from all assets
• Best for investors seeking balanced diversification who don't want any single asset to dominate risk

How often is data updated?

• Real-time data like prices and market cap: updates during trading hours
• Factor scores: recalculated daily after market close
• Portfolio performance metrics: based on historical daily data, updated daily

What file formats are supported for upload?

Three formats: .csv, .xlsx, .txt. Max file size 1MB. Files must contain at least two columns: Symbol and Weight.
