How to Read This Chart

This chart tracks the historical stock price of Bioptic over time. You can switch between daily, weekly, and monthly views and select custom time ranges — from a single day to the full available history. Use the toggle to view price changes in absolute currency terms or as a percentage change relative to the starting date.

Total Return vs. Price Return

The "Total Return" toggle includes reinvested dividends on top of the pure price movement. This is critical because dividends can account for a significant portion of long-term returns. Historically, roughly 40 % of the S&P 500's total return has come from dividends. Always compare total return when evaluating a stock's real performance against a benchmark.

Intraday Price Data

When viewing a one-day time frame, the chart displays real-time intraday price movements. This is useful for observing how Bioptic stock reacts to market openings, earnings releases, or breaking news throughout the trading session.

What to Look For

Look for long-term trends (sustained upward or downward movements over months and years), support and resistance levels (price zones where the stock repeatedly bounces or reverses), and volatility (how much the price fluctuates day to day). Comparing Bioptic's price chart to a market index like the S&P 500 can reveal whether the stock is outperforming or underperforming the broader market.

Income Statement Key Figures

ⓘ

Revenue and Revenue Growth

Revenue is the starting point of every income statement — it measures the total sales Bioptic generates from its core business. Revenue growth (expressed as year-over-year percentage change) is one of the most important indicators of business momentum. Sustained growth above 10 % annually is generally considered strong, while declining revenue is a serious warning sign that demands investigation.

Gross Margin

Gross margin = (Revenue − Cost of Goods Sold) ÷ Revenue. It reveals what percentage of each dollar of revenue Bioptic retains after direct production costs. High gross margins (above 50 %) are typical of asset-light businesses like software and brands, while capital-intensive industries like manufacturing often operate below 30 %. Compare Bioptic's gross margin to industry peers and track it over time to spot improving or deteriorating pricing power.

EBIT and EBIT Margin

EBIT measures operating profit — what remains after subtracting all operating expenses (including R&D, sales, and administrative costs) from gross profit. The EBIT margin shows this as a percentage of revenue. Because it excludes interest and taxes, EBIT allows fair comparisons between companies with different debt levels and tax jurisdictions. A rising EBIT margin indicates improving operational efficiency.

Net Income and Earnings Per Share (EPS)

Net income is the company's final profit after all expenses, interest, and taxes. Dividing net income by the number of shares outstanding gives you EPS — the single most influential metric in stock valuation. Consistent EPS growth is the primary driver of long-term stock price appreciation. Always check whether EPS growth comes from genuine profit improvement or from share buybacks reducing the share count.

Shares Outstanding

The total number of shares Bioptic has issued. A declining share count (through buybacks) boosts EPS and signals management confidence. A rising share count (through stock issuance) dilutes existing shareholders. Always monitor this number alongside EPS to get the full picture of per-share value creation.

Analyst Estimates

The projected figures represent consensus estimates from professional analysts. Compare these forecasts against Bioptic's historical growth rates to assess whether expectations are realistic. A company that consistently beats consensus estimates tends to see its stock price rewarded over time, while repeated misses erode investor confidence.

Bioptic stock margins

The Bioptic margin analysis displays the gross margin, EBIT margin, as well as the profit margin of Bioptic. The EBIT margin (EBIT/sales) indicates the percentage of sales that remains as operating profit. The profit margin shows the percentage of sales that remains for Bioptic.

Bioptic business model & stock analysis

Bioptic Eulerpool Fair Value

Details

Fair Value Estimate

ⓘ

What Is Fair Value?

Fair value is an estimate of what a stock is truly "worth" based on its financial fundamentals, independent of the current market price. If the calculated fair value is above the current share price, the stock may be undervalued — and vice versa. This chart shows three different fair value approaches so you can cross-check them against each other.

Earnings-Based Fair Value

Calculated by multiplying the current earnings per share (EPS) by the average historical P/E ratio over a selected multi-year period. The smoothing over several years filters out temporary spikes or dips. If this fair value exceeds the market price, it suggests the stock is cheap relative to its earning power.

Example: Fair Value (Earnings) 2022 = EPS 2022 × Average P/E 2019–2021

Revenue-Based Fair Value

Derived by multiplying revenue per share by the average historical price-to-sales ratio. This method is particularly useful for companies with volatile or temporarily depressed earnings, as revenue tends to be more stable than profits. It answers: "At what price has the market historically valued each dollar of this company's sales?"

Example: Fair Value (Revenue) 2022 = Revenue per Share 2022 × Average P/S 2019–2021

Dividend-Based Fair Value

Calculated by dividing the dividend per share by the average historical dividend yield. This approach is most relevant for mature, consistently dividend-paying companies. If the resulting fair value is higher than the current price, it implies the stock offers a better yield than its historical average.

Example: Fair Value (Dividend) 2022 = Dividend per Share 2022 ÷ Average Yield 2019–2021

How to Use This Chart

When all three fair value lines converge above the current price, it strengthens the case that the stock is undervalued. When they diverge, investigate why — it may indicate a structural shift in margins, payout policy, or growth rate. The forward estimates on the right extend the analysis using projected fundamentals, helping you assess whether the current price already reflects future growth expectations.

Annual Return

ⓘ

What This Chart Shows

This chart breaks down 's total annual return into two components: price return (gains or losses from stock price movement) and dividend return (income received from dividend payments). Together, they represent the total return an investor would have earned in each calendar year.

Price Return

Price return measures the percentage change in 's stock price from January 1st to December 31st of each year. Positive bars indicate the stock appreciated; negative bars show a decline. This is the component most investors focus on, but it tells only part of the story — especially for dividend-paying stocks.

Dividend Return

Dividend return represents the income generated from dividends paid during the year, expressed as a percentage of the starting stock price. While it may seem small in any single year (typically 1–4 % for established companies), dividends compound significantly over decades and have historically contributed roughly 40 % of total stock market returns.

What to Look For

Examine how many years showed positive vs. negative returns to gauge consistency. A stock with mostly positive years and small drawdowns suggests lower risk. Also compare 's annual returns to a benchmark index — consistently outperforming the market is a hallmark of a strong investment. Pay attention to the worst years: understanding downside risk is just as important as chasing upside potential.
