How to read your brokerage statement

The quarterly brokerage statement arrives, by email or mail, and most people do the same thing: look at the total balance, compare it to last quarter, feel vaguely good or bad about the direction, and move on. Maybe three minutes of engagement.

That's understandable. The statements are dense, formatted to be comprehensive rather than readable, and most of what's in them is not immediately actionable. But there are specific numbers buried in there that matter, and a few that most investors have never looked at.

The sections, defined

A typical Fidelity or Schwab statement has four major sections:

Account Summary shows your beginning and ending balance for the period, net change, contributions, withdrawals, and dividends received. This is the section most people read. It answers "how did I do?", but only at the surface level.

Positions lists every security you hold with the current value, quantity, average cost basis, and unrealized gain or loss. This is where the analytically interesting data lives.

Transaction History records every buy, sell, dividend, and fee that happened in the period. This is where you'd catch errors, confirm a purchase settled correctly, or see exactly what was reinvested.

Performance Summary (present on some statements, absent on others) shows your personal rate of return for the period and sometimes for longer time frames.

Cost basis and why it matters for taxes

Cost basis is the original price you paid for a security, adjusted for splits, reinvested dividends, and return of capital. The unrealized gain or loss on your positions page is calculated against this number.

Why it matters: when you sell, you pay capital gains tax on the difference between your sale price and your cost basis. Selling a position with a very low cost basis means a large taxable gain. Selling a position with a high cost basis (recently purchased and now down) might generate a loss you can use to offset gains elsewhere.

Your statement shows this number. Most investors never look at it until the year they sell.

The wash sale rule

If you sell a position at a loss and buy the same or a substantially identical security within 30 days before or after the sale, the IRS disallows the loss deduction under the wash sale rule. The disallowed loss isn't permanently lost, it gets added to the basis of the repurchased position, but it can disrupt tax-loss harvesting strategies.

If your statement shows a disallowed wash sale amount, that's worth investigating before year-end.

Finding expense ratios

Mutual fund expense ratios do not appear as line items on your statement, they're deducted from fund assets before the NAV you see is calculated. But if you look at the positions section, you can take each fund's ticker symbol and look it up on Morningstar or the fund company's website.

The more useful exercise: calculate your blended expense ratio. Weight each fund's expense ratio by its percentage of your total portfolio and sum the results. That's your effective annual cost as a percentage of assets.

The number most people miss: total fees paid year-to-date

Some statements include a "fees paid" line in the account summary or transaction history. On Fidelity statements, it appears as a line item if any advisory fees were charged. If your statement shows $0 in fees but you're in actively managed funds, that's not because investing is free, it means the costs are embedded in the fund structure and won't appear here.

How Prismfolio handles this automatically

Prismfolio reads your current positions from the brokerage page and calculates your blended expense ratio, current asset allocation, and sector exposure automatically. You don't have to cross-reference ticker symbols or do the weighting math yourself.

The statement is a historical document. Prismfolio gives you the same picture in real time.
