Allocations

The Allocations tab breaks your portfolio down by sector and by individual position so you can see where your money is concentrated. It pairs a summary strip and two pie charts with full sector and holdings tables, all computed as plain percentages of your own holdings. This page explains what the tab shows, how to read each figure, and how the weights are computed. The Allocations tab is available on the Free, Pro Lite, and Pro plans.

Before you begin

Sign in on a plan that allows portfolios. The Allocations tab is available on Free, Pro Lite, and Pro.
Build a portfolio with at least one holding first. For the steps, see Build your first portfolio.
Sector figures use each holding's classification. A holding that cannot be classified is excluded from the sector view, which a note reports.

Quickstart

Open the Allocations tab
Go to the Allocations tab and select the portfolio you want to study.
Read the summary strip
Read the four tiles: number of positions, number of distinct sectors, the weight of your single largest sector, and your top-five concentration.
Study the breakdowns
Compare the By Sector and By Position pie charts, then use the Sector Breakdown and Holdings by Weight tables for the exact percentages and dollar values.

What it shows

The tab reads top to bottom in the following sections.

A four-tile summary strip: number of positions, number of distinct sectors, the weight of your single largest sector, and your top-five concentration (the combined weight of your five biggest positions).
Two side-by-side pie charts: one splitting the portfolio By Sector, one splitting it By Position (the largest twelve positions).
A Sector Breakdown table listing every sector with a weight bar, its percentage of the portfolio, its dollar value, and how many positions sit in it.
A Holdings by Weight table listing every position with a weight bar, its percentage of the portfolio, and its dollar value, sorted largest first.
A small note, when applicable, stating that allocations are based on the holdings that could be mapped and how many were excluded because they could not be classified.

Inputs

This tab has no controls. It reads automatically for the selected portfolio. There are no filters, toggles, or fields. The charts and tables update as your holdings change.

Outputs and how to read them

Positions and Sectors counts: how many holdings you have and how many distinct sectors they span. More sectors generally means more diversification.
Top Sector: the weight of your largest sector. A high number flags sector concentration.
Top 5 Concentration: the combined weight of your five largest positions. A high number flags single-name concentration. For example, a top-five concentration of 70 percent means the rest of your holdings together make up only 30 percent.
By Sector and By Position pies and tables: a visual and numeric read of where weight sits. Long bars and large pie slices are your biggest exposures.
Excluded-holdings note: if some holdings could not be assigned a sector, the percentages are computed over the holdings that could be, and the note tells you how many were left out.

How it is calculated

All figures on this tab are standard percentage math on your own holdings. No proprietary scoring is involved.

Position weight

Each position's weight is its market value as a share of the whole portfolio.

weight = position market value / total portfolio market value × 100

In this formula, position market value is the position's current value in US dollars, and total portfolio market value is the sum of all position values in US dollars. For example, a 100,000 dollar portfolio with a 25,000 dollar position has a weight of 25,000 / 100,000 × 100, which is 25.0 percent.

Sector weight and top-five concentration

Sector weight is the sum of the weights of the positions in that sector, and top-five concentration is the sum of the five largest position weights.

sector weight = sum of (position weight) for positions in the sector; top-five concentration = sum of the five largest position weights

Here position weight is each holding's weight from the formula above, in percent. For example, a book with positions weighted 30, 20, 15, 10, and 8 percent, plus a long tail of smaller names, has a top-five concentration of 30 + 20 + 15 + 10 + 8, which is 83.0 percent. When a holding has no sector classification, it is left out of the sector view and the percentages are computed over the remaining holdings.

Data and timing

Position market values use current quotes from Nasdaq via AlphaVantage. Sector classification for each holding comes from company reference data sourced from AlphaVantage and public filings via EDGAR. The breakdown recomputes with your portfolio's regular update and whenever you add, remove, or change a holding, so it always reflects current weights.

Use cases

Check whether you are over-concentrated in one sector or one stock before adding more.
See your true single-name concentration at a glance with the top-five figure.
Rank your holdings by weight to decide where rebalancing would have the most effect.
Confirm a portfolio is as diversified across sectors as you intended.

Limitations and disclosures

Weights move with prices, so the breakdown reflects market values as of the last update, not your cost basis. Holdings that cannot be classified are excluded from the sector view, and the note reports how many. This tab shows transparent arithmetic on your own holdings and makes no recommendation, so the site-wide disclaimer applies.
