The Multi-Broker Problem: How to Track Your Portfolio When It's Spread Across Nordnet, Kron, and DNB

It starts innocently enough. You open a Nordnet account to buy individual stocks. Then a friend recommends Kron for index funds. Your employer pension sits at Storebrand. You open a DNB account when you get a mortgage. Before long, your financial life is scattered across four providers — and getting a clear picture of your total position requires logging into each one separately.

This is the multi-broker problem, and it affects the majority of Norwegian investors who have been investing for more than a few years.

Why it happens

Norwegian investors spread across brokers for legitimate reasons:

• Different strengths: Nordnet is popular for individual stocks and ETFs. Kron and Sbanken Fond (now Fremtind) are well-regarded for low-cost index funds. DNB, Storebrand, and Gjensidige handle pension products.
• ASK account rules: Some investors open ASK accounts at multiple providers to access different products within the tax-advantaged wrapper.
• Employer pensions: Your OTP pension is wherever your employer chose to place it — you often don't pick the provider.
• Historical decisions: Many Norwegians have accounts at providers they opened years ago and never fully consolidated.

The result is a portfolio that's technically visible — but only in fragments.

Why fragmentation is a real problem

You can't see your actual allocation. If Nordnet shows you 60% in equities, that's only the Nordnet picture. Your Kron account might be 100% global index funds. Your pension might be in a lifecycle fund gradually shifting to bonds. Your combined equity exposure could be very different from what any single dashboard shows.

Rebalancing becomes guesswork. Making a rational decision to rebalance your portfolio requires knowing your total position first. Without it, you might buy more equities on Nordnet while your pension is already overweight equities — without realising.

Cost tracking breaks down. Understanding your true return requires knowing your total invested capital and total current value across all accounts. Broker apps show you their slice. None of them show you the whole.

Dividend and income tracking is incomplete. If you're building towards passive income or tracking yield, you need dividends and distributions from all accounts aggregated in one place.

The spreadsheet trap

The classic solution is a spreadsheet. Many serious investors maintain elaborate Excel or Google Sheets setups with manual entries from each broker, updated monthly or quarterly.

Spreadsheets work — until they don't. The problems are predictable:

• Manual entry is error-prone and time-consuming
• They break when you change providers or add accounts
• Historical performance data is only as good as how diligently you've maintained entries
• They're hard to share or review on mobile
• Most people eventually fall behind and the data becomes unreliable

The maintenance burden means most spreadsheet-based trackers degrade over time, which defeats the purpose entirely.

What a good multi-broker tracking setup looks like

Whether you use a dedicated tool or build your own system, a robust multi-broker tracking setup needs a few things:

A single source of truth for your total portfolio. One place where every holding, across every account, is visible simultaneously. This is the foundation everything else builds on.

Transaction import or sync. Manually entering every buy and sell is unsustainable. The ability to import transaction history from your brokers — even via CSV export — dramatically reduces maintenance burden.

Account-level and total-level views. You want to be able to see each broker account individually (for managing that account) and your aggregate position (for overall decision-making). Both matter.

Cost basis tracking per holding. Knowing what you paid, not just what it's worth now, is essential for understanding actual performance and making withdrawal decisions with tax implications in mind.

Separation of account types. ASK, IPS, and regular brokerage accounts have different tax treatments. A good tracker keeps these distinct while still showing your total picture.

Consolidating — is it worth it?

Some investors solve the multi-broker problem by consolidating to fewer providers. This is sometimes the right answer — fewer accounts means less cognitive overhead and easier tracking.

But consolidation has real costs too. You might lose access to products only available at a specific provider. Moving assets between ASK accounts can trigger taxable events if not done correctly. And some accounts — like employer pensions — simply can't be moved.

For most people, the practical solution is not consolidation but better aggregation: keeping the accounts that serve a purpose, and getting a unified view across all of them without logging in separately to each.

The bottom line

Having accounts at multiple brokers is not a mistake — it's often the rational outcome of building a diversified, tax-efficient investment strategy over time. The mistake is not having a clear view of the whole picture.

Whatever system you use, the goal is the same: one number for your total portfolio value, one view of your allocation, and one place to track performance — regardless of how many accounts sit underneath it.
