Sharesight Alternative: How Zyvo Compares for US Investors

Sharesight is a well-established portfolio tracker, and a genuinely good one for certain investors. This page is an honest, sourced, both-ways comparison — not a takedown — so you can see exactly where each product is actually stronger.

Where Sharesight genuinely wins: multi-country tax depth

Sharesight has been building portfolio-tracking tools for nearly two decades and now serves more than 500,000 investors worldwide. That history shows up most clearly in tax reporting: Sharesight produces a full capital-gains-tax calculation — not just a list of realized gains, but the actual computed tax figure using each country's own rules — for Australian and Canadian tax residents specifically. If you file taxes in either country, that's a meaningfully deeper tool than a cost-basis export.

Sharesight also integrates directly with Xero, which matters if you or your accountant already run bookkeeping through it, and offers a dedicated Business plan built for accountants and advisors managing multiple client portfolios — a flat $13.50 per portfolio, regardless of trading volume. Zyvo doesn't have an advisor tier today. If you're managing client accounts professionally, or you specifically need Xero, Sharesight's ecosystem is the more mature choice.

Where Zyvo pulls ahead: risk visibility and fresher price updates

Zyvo's tax tool works differently. Rather than a cost-basis export, it estimates the actual US federal tax owed on your realized gains — with short-term and long-term gains stacked correctly against your filing status and income, and the 3.8% Net Investment Income Tax applied where it should be. This is US federal only — Zyvo doesn't cover state tax or any country outside the US — but for a US taxpayer specifically, it goes a step further than Sharesight's own US offering. Sharesight's US "Sold Securities Report" lists your realized gains for your accountant; it doesn't calculate the tax owed, because Sharesight's full CGT calculation is limited to Australian and Canadian tax residents.

Zyvo also adds portfolio concentration risk analysis using the Herfindahl-Hirschman Index, so you can see whether your risk is quietly concentrated in one or two positions, not just how many tickers you hold. Prices also refresh automatically, up to every 60 seconds — though the underlying market data can be delayed up to 15-20 minutes depending on the exchange, on either side. And everything sits on one flat plan: no tax reports gated behind a higher tier, no holdings cap pushing you to upgrade.

Pricing, side by side

Zyvo's single plan roughly matches Sharesight's Standard tier on holdings and multi-currency support, at less than half the price. Sharesight's Free and Starter plans are cheaper than Zyvo, but cap you at 10 or 30 holdings and, on the Free plan, skip tax reports entirely.

Who should actually pick Sharesight

Sharesight is the better fit if any of these describe you: you're an Australian, New Zealand, or Canadian tax resident who needs a fully computed capital-gains tax figure, not just a transaction list; you're a financial advisor or accountant managing several client portfolios and want a dedicated Business plan built for that; you already run your books through Xero and want direct integration; or you simply want the reassurance of a platform with a longer track record and a much larger existing user base. None of these are things Zyvo currently offers — that's not a knock on either product, just a difference in who each one was built for first.

Who should actually pick Zyvo

Zyvo is the better fit if you're a US-based DIY investor with holdings scattered across multiple brokers and you want one consolidated view of true performance, not just a balance. That's especially true if you want your actual estimated US federal tax bill calculated automatically, rather than a cost-basis export you still have to run through a calculator yourself; if you want prices that refresh automatically throughout the day instead of a fixed 15-20 minute delay; or if you're specifically trying to understand how concentrated your risk actually is across everything you hold. It's also the simpler choice if you'd rather pay one flat price for everything than work out which tier unlocks which feature.

Built for US-based investors specifically

A lot of the difference on this page comes down to one thing: Sharesight was built first for Australian and New Zealand investors, with US support added on top. Zyvo was built US-first. In practice, that shows up in a few concrete places rather than as a general claim — the tax report's FIFO method is the same default assumption behind IRS Form 8949 / Schedule D, the federal tax estimate is calculated directly from your filing status and taxable income instead of being left as a plain cost-basis export, and broker consolidation covers 30+ US and international brokers plus CSV import for anything else. None of this replaces an accountant — it's meant to get you to one with the right numbers already worked out, not to file on your behalf.

Tax reporting: one click between FIFO and Average Cost

Zyvo's tax report isn't a single fixed calculation. You can switch between FIFO and Average Cost (ACB) and watch realized gains recalculate immediately, using actual lot-by-lot tracking rather than an approximation. That choice matters because the two methods can produce meaningfully different numbers on identical trades, and which one applies depends on where you file: FIFO is the default assumption behind US Form 8949, while Average Cost (ACB) matches Canada's Adjusted Cost Base on Schedule 3.

To be direct about the boundary, since it matters: Zyvo's tax-owed estimate itself — short-term/long-term gain stacking, the 3.8% Net Investment Income Tax — is US federal only. It doesn't calculate state tax, and it doesn't produce a country-specific capital-gains figure the way Sharesight's Australian and Canadian tooling does. This isn't full global tax compliance, and we'd rather say that plainly here than have you find out after relying on it.

Concentration risk, with the actual thresholds

Sharesight doesn't have a concentration or diversification metric at all — nothing in the product flags whether half your portfolio is sitting in one stock. Zyvo computes a Herfindahl-Hirschman Index (HHI) across your whole portfolio, and separately watches individual positions: a warning appears once any single holding passes 25% of total portfolio value, escalating to a critical alert at 40%. Both thresholds are adjustable in your alert preferences, and a dismissed alert isn't dismissed forever — it re-checks as the position's weight changes, so a dismissal from months ago can't quietly mask a portfolio that's since become genuinely concentrated.

Proactive alerts Sharesight doesn't have

Beyond the concentration check above, Zyvo runs four more automatic checks in the background: whether a position is approaching the one-year mark that could qualify it for lower long-term capital-gains rates if you hold a little longer; how your time-weighted return compares to a benchmark index; whether a connected broker's sync has failed or gone stale; and the single-holding weight check described above. That's five alert types in total, all surfaced through an in-app notification bell with its own dismiss and preferences panel. To be clear about what this is and isn't: there's no email, push, or SMS delivery today — you'll see these when you have the app open, not as an unprompted alert to your phone. Sharesight has no equivalent system.

Try it yourself — no signup required

Rather than take either side of this comparison at face value, you can open a real, fully functional sample portfolio at zyvotracker.com/demo with no account, no email, and no credit card. It's seeded with sample data, not blank, so you can look at the tax report, the concentration numbers, TWR/IRR, and the alerts described above exactly as a real user would see them, before deciding anything.
