ⓘHow to Read This Chart
This chart tracks the historical stock price of ClearSign Technologies 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.

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.

Intraday Price Data
When viewing a one-day time frame, the chart displays real-time intraday price movements. This is useful for observing how ClearSign Technologies 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 ClearSign Technologies'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 ClearSign Technologies 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 ClearSign Technologies 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 ClearSign Technologies'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 ClearSign Technologies 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 ClearSign Technologies'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.

ClearSign Technologies business model & stock analysis
ClearSign Technologies SWOT Analysis
Strengths
Clearsign Technologies Corp has developed innovative and patented technologies in the combustion industry, providing them with a unique competitive advantage. Their advanced combustion systems offer improved energy efficiency, reduced emissions, and increased operational flexibility.
The company has a strong intellectual property portfolio, which includes key patents and proprietary designs. This strengthens their position in the market and offers potential licensing opportunities to generate additional revenue.
Weaknesses
Clearsign Technologies Corp currently operates in a highly competitive market with well-established players. As a relatively smaller company, they may face challenges in penetrating and gaining market share.
Their technologies require significant customer education and adoption efforts. The transition from traditional combustion systems to Clearsign's innovative solutions may be met with resistance and skepticism from potential customers.
Opportunities
Increasing global environmental regulations and growing concerns over carbon emissions create a favorable market environment for Clearsign Technologies Corp. Their environmentally friendly solutions can help companies comply with stricter regulations and reduce their carbon footprint.
The company has the opportunity to expand its product offerings into various industries that rely heavily on combustion, such as power generation, oil and gas, and chemical production. These industries present significant growth potential and demand for advanced combustion technologies.
Threats
Clearsign Technologies Corp faces the risk of larger competitors developing similar technologies or acquiring patents that could compete with theirs. This could potentially erode their competitive advantage and market position.
Economic downturns and decreased capital expenditure in industries they serve may negatively impact the demand for their products. Additionally, delays or cancellations of infrastructure projects can pose a threat to their revenue stream.

ClearSign Technologies Eulerpool Fair Value

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.
