Look through funds, stocks, sectors, and benchmark active weights

Free Portfolio Look-Through Tool

See what you really own beneath your funds and stocks.

PortfolioSight breaks a portfolio into underlying holdings, direct exposure, fund exposure, sector weights, benchmark weights, and active weights. Enter tickers manually or upload a simple CSV to drill into your portfolio in one place.

How the Portfolio Drilldown Works

A simple workflow for seeing your true portfolio exposure.

1. Add holdings

Enter ticker and weight pairs or upload a CSV. Weights can be entered as decimals or percentages.

2. Analyze exposure

The tool combines direct stock positions with underlying fund holdings to estimate aggregate security and sector exposure.

3. Compare active weights

Review portfolio weight, benchmark weight, and active weight to spot concentrations, gaps, and unintended bets.

Inputs

Upload a CSV or manually enter ticker/weight pairs.

Manual Positions

Enter one fund, ETF, stock, or ticker per row with its portfolio weight. These rows replace the old comma-separated Funds and Weights fields.

Fund / Ticker	Weight

Use decimals like 0.70 / 0.30, or percentages like 70% / 30%.

Custom Benchmark Index

Enter ETF/fund tickers and weights to build a custom benchmark from SEC N-PORT holdings. This replaces the default ITOT-only benchmark weights when you run the analysis.

Default: ITOT 100%

Benchmark Fund / Ticker	Weight

Example: ITOT,0.70 and VXUS,0.30. Leave blank to use the backend's default benchmark data.

Active Weight Profile

Active Share estimates how different the portfolio is from the benchmark based on security-level active weights.

Equity Sector Weights

Sector weights are shown as a percent of equity exposure only. Bonds and cash-like holdings are excluded here and shown in Asset Allocation.

Run the holdings analysis to render the equity sector chart.

Asset Allocation

Total portfolio weight grouped by N-PORT asset category, so bond exposure shows separately instead of being forced into sector buckets.

What to Look For

Use the drilldown to make faster portfolio review decisions.

Concentrated holdings

Large total weights can reveal single-company exposure that is hidden across multiple ETFs or mutual funds.

Sector tilts

Sector weights help identify whether performance is being driven by broad allocation choices or stock-level selection.

Benchmark gaps

Active weight highlights where the portfolio differs most from the benchmark, including names not currently owned.
