What the Allocation page is for#
Allocation answers "how is my money divided?" It slices the portfolio by asset type and by market sector, then compares the result to the mix you actually want. Open it from the sidebar or press g then a.
This is the page for checking balance, not performance. A portfolio can be up and still dangerously concentrated.
The two breakdowns#
Two sections stack on the page:
- Asset Allocation splits money by asset class: Equity, ETF, Fixed Income, Cash, and Other.
- Sector Allocation splits stock and fund money by industry sector. Pyx looks inside your funds to do this, so an S&P 500 ETF contributes its technology weight to Technology, not to a generic "fund" bucket. Anything that cannot be classified lands in Unclassified rather than being silently dropped.
Why lookthrough matters, and why "one fund" is not "one bet", is covered in diversification, sector exposure, and drift.
Three ways to draw it#
- Donut: a ring chart. Big slices jump out.
- Bar: horizontal bars. Best for comparing sizes precisely.
- Treemap: nested rectangles sized by value. Most detail per screen.
A second toggle switches Summary (top-level groups) against Detailed (each group broken into its holdings).
The legend table#
One row per category, below the chart:
| Column | Meaning |
|---|---|
| Asset Class / Sector | The category |
| Value | Dollars in that category |
| Weight | Percent of the portfolio |
| Drift | Distance from your target weight |
Click a row to expand the securities inside it. Drift shows a dash until you set targets.
Set target weights and watch drift#
Drift is the point of this page. Decide the mix you want, say 60% equity, 30% fixed income, 10% cash, and enter it under Settings, Allocation. From then on the Drift column shows the gap between plan and reality. "+2.4%" means that category is 2.4 percentage points over target.
When total drift crosses your threshold, 2% by default, Pyx highlights the summary so it stands out.
Pyx shows the drift. It does not place trades or tell you what to buy. The decision stays yours.
Markets move every day, so drift is normal. What matters is noticing when it gets large, because at that point your real risk no longer matches the plan you made. The mechanics of rebalancing are explained in the diversification guide.
Exclude cash from the picture#
A large cash balance can make an invested mix look more conservative than it is. Turn on Exclude cash to drop cash from the chart and rescale the remaining slices to 100%. Settings, Allocation can make this the default.
Click into the chart#
The donut and treemap are interactive:
- Click a slice to drill into it. A breadcrumb trail leads back out.
- Cmd-click a slice to jump to Holdings filtered to that category.
- Right-click a slice for a menu: open in Holdings, copy weight, drill in.
Hovering a donut slice fills the center with its summary. Whether that center leads with dollar value, weight, or name is configurable under Settings, Allocation.
Compare accounts side by side#
Select two or more accounts at the top and the page switches to compare mode: one small donut per account. Useful when your Roth IRA is supposed to be aggressive and your taxable account is not, and you want to verify both at a glance.
Concepts behind this page#
Allocation is the practical end of diversification. The idea that a portfolio's risk comes from how its pieces move together, not from any single piece, is what target weights are protecting. Diversification, sector exposure, and drift covers the concept, including why sector lookthrough changes what your portfolio actually is.
