Track stocks with real-time quotes, account-level context, and net worth impact across investments, banking, and budgeting.
Definition first
This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
Your stocks are on Fidelity. Your Roth IRA is at Schwab. You have a few shares on Robinhood from 2021. Your 401k is wherever your employer picked. To know your actual net worth, you'd have to log into four different apps, mentally add the numbers, and still not know how much of your wealth is in equities vs. cash. Or you could use a portfolio tracker that shows everything in one place.
Why Brokerage Apps Aren't Enough
Every brokerage has a portfolio view. Fidelity's is decent. Schwab's is fine. But they all share the same fundamental problem: they only show what's in that brokerage.
The average investor in 2026 has 2.8 brokerage accounts. That means 2.8 separate apps, 2.8 different views of your money, and zero unified picture. Here's why that happens:
Your 401k is at your employer's provider; you didn't choose it, and you probably can't move it
Your Roth IRA is at a different brokerage; you opened it when had a promotion in 2019
You have a taxable account at Fidelity — because their index funds have zero expense ratios
You have leftover shares on Robinhood; from when you were day trading during COVID
Your spouse has their own accounts; at yet another brokerage
You can't answer basic questions:
What percentage of my portfolio is in tech stocks across all accounts?
What's my total dividend income across all accounts?
How much of my net worth is invested vs. sitting in cash?
Am I overweight in any single stock across brokerages?
What's my overall performance this year; not per account, but total?
Brokerage apps are great for trading. They're terrible for portfolio management.
What a Good Stock Portfolio Tracker Does
1. Aggregates All Accounts
Connect every brokerage; Fidelity, Schwab, Vanguard, Robinhood, E*TRADE, TD Ameritrade, Merrill Lynch, Wealthfront, Betterment; through one secure connection. See every holding, every account, in one view.
The best trackers use Plaid for brokerage connections. It's the same provider banks use — Venmo, Robinhood, and 12,000+ financial apps connect through Plaid. Read-only access; the tracker can see your holdings but can't place trades or make any changes to your accounts. (Connecting all your accounts to any third-party app is a real privacy tradeoff; we address this honestly in the privacy section below.)
What to look for: Some trackers only support "major" brokerages. Make sure yours supports your 401k provider; those are often the largest accounts and the hardest to track manually (Empower, Voya, Principal, TIAA, etc.).
2. Real-Time Market Data
Delayed quotes are useless for anyone who checks their portfolio regularly. A good tracker provides real-time or near-real-time quotes from providers like Finnhub, so you see current prices; not 15-minute-old data.
Beyond individual stock quotes, you want to see market context: how the S&P 500, Dow Jones, NASDAQ, and Russell 2000 are performing relative to your portfolio. If the S&P is up 1.5% today and your portfolio is up 0.5%, that context matters.
Why Finnhub? Finnhub provides institutional-grade market data with real-time quotes, company profiles, and search; all accessible via API. Trackers built on Finnhub give you real-time market data without paying for a Bloomberg terminal.
3. TradingView-Quality Charts
You shouldn't need to open TradingView in a separate tab. The best portfolio trackers embed professional-grade charts; candlesticks, indicators, drawing tools — directly alongside your holdings. When you click on a stock in your portfolio, you should see:
Drawing tools for trend lines and support/resistance
Volume bars overlaid on price
Clarity embeds actual TradingView widgets; the same charts millions of traders use daily — directly in your dashboard. No iframe hacks or simplified knockoffs.
4. Net Worth Context
Your stock portfolio is part of a bigger picture. A tracker that shows stocks alongside your bank accounts, crypto, and other assets tells you what percentage of your net worth is in equities; and whether you need to rebalance.
This is especially important for younger investors who might have 95% of their net worth in stocks without realizing it. Or retirees who need to ensure they have enough in cash and bonds to cover 2-3 years of expenses.
Most brokerage apps show dividends per account. A portfolio tracker shows total dividend income across all your accounts; the number that actually matters for financial planning.
6. Sector & Allocation Analysis
"I'm diversified; I own 20 stocks." But if 15 of them are tech companies, you're not diversified. A good tracker breaks down your portfolio by:
Sector: Technology, Healthcare, Financials, Consumer, Energy, etc.
Geography: US, International Developed, Emerging Markets
Account type: Taxable, Roth IRA, Traditional IRA, 401k
Individual position: No single stock should be 20%+ of your portfolio
Benchmarking: Why It Matters and What to Track
Individual stock performance means nothing in isolation. If your portfolio returned 12% but the S&P 500 returned 15%, you underperformed; and would have been better off in an index fund. Benchmarking against relevant indices helps you evaluate whether your stock picks are actually adding value.
Key Indices to Benchmark Against
S&P 500; the US equity benchmark. 500 largest US companies by market cap. If you only track one index, this is it. Most actively managed funds fail to beat it over 10+ year periods.
NASDAQ Composite; tech-heavy index. If your portfolio leans toward growth and technology, this is the relevant benchmark; not the S&P.
Russell 2000; small-cap barometer. If you hold small-cap stocks, compare against this instead of large-cap indices.
MSCI EAFE; international developed markets (Europe, Australasia, Far East). The benchmark for non-US holdings.
A good portfolio tracker lets you overlay your portfolio performance against these indices over matching time periods; so you can see whether your active decisions are earning their keep or whether you'd be better off indexing.
How Clarity Tracks Stocks
Clarity connects to your brokerage accounts via Plaid; the same provider used by Venmo, Robinhood, and most fintech apps. Here's what you get:
All brokerages in one view: Fidelity, Schwab, Vanguard, Robinhood, E*TRADE, Merrill, and more; aggregated automatically
Real-time quotes: Live pricing via Finnhub for every stock in your portfolio and watchlist
TradingView charts: Full charting suite embedded directly in your dashboard; no switching tabs
Watchlist: Track stocks you're interested in, even if you don't own them yet. Mix stocks, crypto, forex, and commodities in one list
Net worth integration: Stocks + crypto + bank accounts + budgets, all in one number
Historical snapshots: Track your net worth over time; daily snapshots show growth, drawdowns, and trends
Portfolio Allocation: Why It Matters More Than Stock Picks
Here's an uncomfortable truth: asset allocation is one of the biggest drivers of long-term returns. Not stock picks. Not timing. Allocation.
The influential Brinson, Hood, and Beebower study found that how you divide money between stocks, bonds, cash, and other asset classes explains the vast majority of portfolio performance variation. The exact magnitude; often cited as "90%+" — has been debated and refined in subsequent research, but the core insight holds: allocation decisions matter far more than individual security selection. Yet most investors obsess over which stocks to buy and ignore whether they should be 60% stocks or 80% stocks.
A portfolio tracker that only shows stocks misses the point. To manage allocation, you need to see:
Equities %: How much of your net worth is in stocks?
Cash %: How much is sitting idle in checking/savings?
Crypto %: Growing asset class that affects overall risk
Fixed income %: Bonds, CDs, money market funds
Real estate %: REITs, property equity (if tracked)
Clarity shows all of these. Not just your stock portfolio; your entire allocation. That's the view that actually drives good financial decisions.
Stocks + Crypto + Cash = The Complete Picture
Most stock trackers; Personal Capital, Stock Events, Delta — show you stocks and sometimes crypto. But they miss the other half of your financial life: bank accounts, budgets, subscriptions, and spending.
Clarity gives you the full stack:
Investments: Stocks, ETFs, mutual funds across all brokerages
Crypto: Exchange balances and on-chain wallets via CCXT and Alchemy
Cash: Checking, savings, credit cards, loans via Plaid
Your portfolio allocation only makes sense when you see the whole picture. If 80% of your net worth is in stocks and you have 2 months of expenses in savings, that's a risk worth knowing about. If you're saving $3,000/month but spending $2,800, that context changes how aggressively you should invest.
Stock Portfolio Tracker Comparison: Clarity vs. the Competition
Disclosure: This article is published by Clarity, so take our self-assessment with appropriate skepticism. We've tried to be fair in describing competitors' strengths and weaknesses, but we'd encourage you to try the tools yourself; most offer free tiers or trials.
Empower (formerly Personal Capital)
Empower (rebranded from Personal Capital in 2023) was the original portfolio aggregator and remains one of the most established options. Its free tools are genuinely strong — especially for retirement planning.
Pros: Excellent account aggregation, best-in-class retirement planner, fee analyzer, investment checkup tool, free tier with no time limit
Cons: Also offers paid wealth management (0.89% AUM), which means you may get advisor outreach; limited crypto support, no DeFi tracking, no budgeting tools
Best for: Investors focused on retirement planning who want robust free tools and don't need crypto or budgeting features
Stock Events
Stock Events focuses on dividend tracking and earnings calendars. It's a mobile app with a clean UI but limited scope.
Pros: Excellent dividend tracking, earnings calendar, clean mobile UI
Cons: Manual portfolio entry (no Plaid), limited to stocks, no bank/crypto, mobile only
Best for: Dividend investors who want a dedicated mobile tracker
Yahoo Finance
Yahoo Finance is free and has good market data, but its portfolio tracking is basic; manual entry, no account connections, no net worth.
Pros: Free, comprehensive market data, good news coverage, large community
Cons: Manual portfolio entry only, no Plaid, no crypto wallets, no bank tracking, ads everywhere
Best for: Casual investors who want free market data and news
Clarity
Pros: All-in-one (stocks + crypto + banks + budgets), Plaid for automatic account sync, real-time Finnhub quotes, TradingView charts, watchlist across all asset classes, historical net worth tracking, AI insights, $99/year
Cons: Newer product, no dedicated retirement planner (yet)
Best for: Modern investors who want stocks, crypto, and banking in one dashboard
Tax-Loss Harvesting: When to Sell
A good portfolio tracker doesn't just show gains; it shows losses too. And losses have value. Tax-loss harvesting means selling losing positions to offset gains elsewhere in your portfolio.
Here's how it works: You have $5,000 in gains from selling NVDA. You also have a $3,000 unrealized loss on a stock that's underperformed. Sell the loser, realize the $3,000 loss, and your taxable gains drop from $5,000 to $2,000. At a 24% tax rate, that's $720 saved.
To harvest losses effectively, you need a tracker that shows unrealized gains and losses across all accounts; not just one brokerage. Clarity tracks cost basis and P&L across every connected account, making it easy to spot harvesting opportunities.
The Retirement Account Problem
For most Americans, their largest investment account is their 401k or employer retirement plan. But it's also the hardest to track:
Separate platform: 401k providers (Empower, Voya, Fidelity NetBenefits, Principal) have their own apps that don't connect to anything else
Limited investment options: You can't see how your 401k target date fund overlaps with your individual stock picks elsewhere
Contribution tracking: How much have you contributed this year? Are you on track to max out? (The IRS sets contribution limits annually; $23,500 for 2026. Check IRS.gov for the current year's limit.)
Employer match: Is your employer match vesting? How much is actually "yours"?
Connecting your 401k to Clarity via Plaid solves all of these. You see your retirement account alongside everything else; with the same real-time updates.
A Note on Privacy and Data Aggregation
Connecting all your financial accounts to a single app is a real tradeoff worth acknowledging. You're giving a third party read-only access to your complete financial picture; balances, transactions, holdings — in exchange for the convenience of a unified view.
Here's what to consider when evaluating any portfolio tracker:
Connection method: Plaid (used by Clarity and most fintech apps) provides read-only access; the tracker can see your data but cannot move money or place trades
Data storage: Does the tracker encrypt your data at rest and in transit? Clarity uses AES-256 encryption for stored data and TLS for all connections.
Data retention: What happens to your data if you cancel? Look for trackers with clear deletion policies.
Business model: If the product is free, consider how the company makes money. Ad-supported trackers may monetize your financial data. Subscription-based trackers (like Clarity at $99/year) are incentivized to protect your data, not sell it.
No tracker; including Clarity — can eliminate this tradeoff entirely. The question is whether the visibility into your finances is worth the data exposure. For most people with accounts spread across multiple institutions, the answer is yes — but it's a decision worth making deliberately.
