Exposure X-Ray - See what you actually own across all your accounts

Q: Does this work with 401(k)s and IRAs?

Yes. Connect any account: Traditional and Roth IRAs, 401(k), 403(b), 457 plans, Taxable brokerage, HSAs, 529s, trusts. Exposure X-Ray analyzes all types together.

Q: Will this show if I own the same stocks in different funds?

That's exactly what it's built for. Exposure X-Ray shows every stock in every fund across every account, revealing overlaps like Apple appearing in VOO, VGT, and QQQ with different percentages.

Q: How often does this update?

Real-time prices, daily portfolio updates. Updates as you trade, funds rebalance, and markets move. Always current.

You could own Apple through six different ETFs. A single stock is 21% of your wealth without you knowing. Exposure X-Ray shows every investment exposure in every account.

Your "different" funds hold the same 80 stocks. Did you know that?

You own VOO and QQQ. Most of QQQ is already in VOO.

You own the Mag 7 three times over. That's concentration, not diversification.

Your Fidelity 401(k) doesn't know about your Vanguard IRA.

Is Exposure X-Ray for you?

If any of these sound familiar, you need to see what you actually own.

You own ETFs or mutual funds

The setup

VOO for S&P 500. VTI for total market. QQQ for tech. Plus a 401(k) target-date fund. Different funds, different purposes. Diversified, right?

What You Don't See

All four hold the same mega-cap tech—Apple, Microsoft, Amazon, Google, Meta. You could be 30-40% tech without knowing.

What Exposure X-Ray Shows

VOO and VTI share 500 stocks. You're exposed to the same companies twice. See the overlap. Decide what to cut.

You have accounts at multiple brokerages

The setup

Different brokerages have different funds that track the same thing. FXAIX with Fidelity and VOO with Vanguard? QQQ with your E*Trade account and SCHG in Schwab?

What You Don't See

Fidelity target-date 2050: 30% tech. Vanguard total market: 28% tech. Your Schwab stocks? Already your largest holdings through your funds. You're more concentrated than any account suggests.

What Exposure X-Ray Shows

Each brokerage has its own fund to help you track the same basket of stocks. FXAIX and VOO are both tracking the S&P 500. This means you're just paying multiple fees across different brokerages for the same exposure.

Your advisor says you're "diversified"

The setup

Your advisor manages $800K. Solid portfolio, mostly index funds. But they don't manage your 401(k) ($400K), old IRA ($200K), or spouse's accounts ($300K).

What You Don't See

They're optimizing on 40% of your assets. Their recommendations might create concentrations with your other accounts. Not their fault—incomplete information.

What Exposure X-Ray Shows

Everything. Your advisor's conservative allocation plus your aggressive 401(k) might be riskier than intended. Share your X-Ray so you can have a better-informed conversation.

What Mezzi members discovered

"Here's what surprised me most: I discovered individual stock exposure I didn't even know I had. Turns out my "diversified" ETF portfolio had significant overlap, with some companies appearing across multiple funds."

— Nishant Jayant, Meta engineer

"The hidden concentration is such a good feature. Particularly for those in tech who already hold significant amount of company stock. They often forget those same holdings make up a large % of the indexes they hold."

— Andre Nader, author of FAANG FIRE

Most financial advisors don't have access to this analysis

Exposure X-Ray uses institutional-grade analysis—reserved for the wealthiest clients.

Your advisor probably uses:

Morningstar: Fund-level analysis, not your real-time cross-account overlap.
Planning tools: eMoney, RightCapital, MoneyGuidePro—only categorize funds.
Brokerage reporting: Isolated to that brokerage and that account.

They don't have tools that analyze every holding across all accounts.

What makes Exposure X-Ray different:‍

Every stock in every fund across every account
True exposure to each company
Sector, market-cap, and geographic concentrations
Updates automatically

Even sophisticated DIY investors can't calculate this manually. Too many moving parts.

Frequently asked questions

How is this different from my brokerage's portfolio view?

Your brokerage shows what you hold with them. Exposure X-Ray shows what you own across all accounts.

Example: Fidelity shows "You own VOO, diversified." But you own VTI at Vanguard and QQQ at Schwab. You're heavily concentrated in mega-cap tech. Fidelity can't see your other accounts. Exposure X-Ray can.

Does this work with 401(k)s and IRAs?

Yes. Connect any account:

Traditional and Roth IRAs
401(k), 403(b), 457 plans
Taxable brokerage
HSAs, 529s, trusts

Exposure X-Ray analyzes all types together.

Will this show if I own the same stocks in different funds?

That's exactly what it's built for.

You own VOO, VGT, and QQQ. Exposure X-Ray shows:

Apple in all 3 (7.1%, 18.4%, 11.2% of each)
Microsoft in all 3 (6.9%, 16.7%, 9.8%)
Total Apple: 12.3% of your portfolio

Every stock. Every fund. Every account.

How often does this update?

Real-time prices, daily portfolio updates. Updates as:

You trade
Funds rebalance
Markets move

Always current.

What if I want to be concentrated?

That's fine. Some investors intentionally concentrate in sectors they understand.

Exposure X-Ray shows what you own. You decide what to do. Want 40% tech? Great—just know that's what you have.

Is my data secure?

Yes:

Bank-level encryption
Read-only access (can't move money or trade)
Plaid and Meld (trusted by every major bank)

Stop guessing what you own.

The next market correction will reveal whether you're diversified or concentrated. Better to find out now.
