What Luum is and isn't
Luum is a tracking, analysis and tax-record layer over accounts you keep somewhere else. It reads your holdings, computes things from them, and hands you the output. That's the whole shape of it.
Knowing where the edges are saves time, so here they are.
Luum is not a broker
You cannot buy or sell anything through Luum. There's no order path anywhere in the product, including on the Rebalance page — that simulator tells you what trades would move you toward your target, and then you place them at your brokerage or you don't.
Brokerage connections are read-only by construction: Luum can read positions and transactions and can do nothing else. It cannot place trades, move cash, or change a setting at your institution. Your credentials are never seen or stored — authorisation happens on your institution's own login page. See Connecting your brokerage.
Luum does not hold your money
No cash, no securities, no custody. Everything you see is a record of assets held elsewhere.
The practical consequence: deleting your Luum account deletes Luum's records and touches nothing you own. Your brokerage remains the system of record, and if the two disagree, your brokerage is right.
Luum does not give advice
Nothing in the product is a recommendation, a suitability assessment, or a directive to trade. There is no screener that tells you what to buy, no model portfolio, and no "we suggest" anywhere.
What it does instead is surface figures and let you sort them. A Ticker Score reads published fundamentals against fixed, absolute thresholds — there is no peer group and no sector cohort. An Insight flags a condition that met a rule. Strategy commentary describes your portfolio against the goal you set. Every one of those is an input to a decision you make.
Your investor profile shapes how that analysis is worded — it is not a suitability determination.
Luum does not file your taxes
The Tax Centre computes realized gains, tracks ACB, and exports a CRA-style Schedule 3 summary or a 1099-B style disposition list. Luum does not apply or flag superficial losses — if you sold at a loss and bought back within 30 days either side of the sale, that adjustment is yours to make. You or your accountant do the filing, and you should verify the figures before you do — they're estimates derived from the transaction data Luum was given. See The Tax Centre.
Luum is not a trading feed
Prices refresh on an interval measured in minutes, not seconds, and the timestamp shown is the provider's. It's built for tracking a portfolio, not for timing an order.
What Luum is only as good as
Every number here is computed from data you supplied. Three things decide whether the output is worth anything:
- Complete transaction history. Returns, ACB and realized gains are all derived from it. A portfolio imported as a bare holdings list can show you what you own and very little else.
- Correct account types. Tax treatment follows the account type on each holding, and it cannot be inferred later. See Portfolios and accounts.
- Matched securities. A holding Luum couldn't match to a market instrument sits at book value and never moves.
None of these are things Luum can fix on your behalf, which is why the setup articles keep returning to them.
What it's genuinely good at
Worth stating too, since the list above is all limits. One picture across accounts that don't talk to each other; return figures that account for your contribution timing; an ACB that survives a decade of partial sales; and noticing the concentration that crept up on you while you weren't looking.
