How to Read Stock Fundamentals Inside Your Portfolio Tracker (2026)

How to access fundamentals in PortfolioTrackr

Every position row in your portfolio has a small fundamentals button. Click it to expand an inline panel below the position showing the key metrics pulled fresh from global market data providers. The data is cached for 24 hours so it loads instantly on repeat views. You can expand and collapse each position independently without losing your place in the table.

P/E ratio — trailing and forward

The P/E ratio (Price-to-Earnings) is the most widely used valuation metric. It's calculated simply: current stock price ÷ earnings per share. It tells you how much the market is willing to pay for each dollar of profit the company earns.

PortfolioTrackr shows two versions. The trailing P/E uses the last 12 months of actual reported earnings — it's based on what the company has already done. The forward P/E uses analyst consensus estimates for the next 12 months — it reflects where the market expects the company to be. When a forward P/E is significantly lower than the trailing P/E, it often means analysts expect earnings to grow, which is generally a positive signal.

A high P/E doesn't automatically mean expensive, and a low P/E doesn't automatically mean cheap — context matters. A P/E of 35 might be reasonable for a software company growing revenue at 30% per year, and high for a bank growing at 5%. The most useful thing to do is compare the P/E against the company's own historical average and against peers in the same sector.

EPS — trailing and forward

EPS (Earnings Per Share) is net profit divided by the number of shares outstanding. It's the actual dollar amount the company earned per share. The trailing EPS is calculated from the last four quarters of reported results — audited, real numbers. The forward EPS is the analyst consensus forecast for the next 12 months.

EPS growth is one of the core drivers of long-term stock price appreciation. If a company consistently grows EPS year on year, the stock price tends to follow over time. A forward EPS significantly above trailing EPS signals that analysts expect the company to grow — which explains why some stocks trade at seemingly high P/E ratios (the market is paying for expected future earnings, not past ones).

Market capitalisation

Market cap is the total value of all shares outstanding at the current price. It's simply share price × total shares outstanding. It tells you the size of the company as the market values it right now — not its revenue, not its assets, but what investors as a collective are willing to pay for 100% of the business today.

Market cap is useful for position sizing decisions. A $2 trillion company (Apple, Microsoft) behaves differently from a $500 million small cap. Large caps tend to be more stable and liquid; small caps can move more dramatically in both directions. Knowing the market cap of each position at a glance helps you understand the risk profile of your overall portfolio.

Annual revenue

Revenue (also called turnover or the top line) is the total income the company generated from its core business before any expenses are deducted. Unlike earnings (profit), revenue is harder to manipulate — you either sold something or you didn't. Fast-growing revenue in an early-stage company can justify high P/E ratios even when current earnings are low, because the market is pricing in future profitability.

Comparing revenue to market cap gives you the Price-to-Sales (P/S) ratio, which is useful for companies that aren't yet profitable. A company with $10 billion in revenue and a $20 billion market cap (P/S of 2x) is priced very differently from one with $1 billion in revenue and a $20 billion market cap (P/S of 20x).

Using fundamentals alongside your P&L

The real value of having fundamentals inside your portfolio tracker — rather than in a separate research tool — is that you can cross-reference your live P&L with the underlying business quality in one screen. A position showing a 40% gain might look great, but if the forward P/E has expanded from 20x to 45x since you bought it while EPS estimates have only gone up slightly, the valuation may have stretched significantly. Conversely, a position down 15% where EPS estimates have actually risen and the P/E has compressed can look like a buying opportunity.

None of this replaces proper research, but having the numbers in front of you while you're reviewing your positions makes better decisions more likely.
