Is CLIR overbought or oversold?
At the September 3, 2026 close, CLIR's RSI(14) was 50.0, in neutral territory (between 30 and 70). The MACD histogram was negative, so short-term momentum leaned bearish at that close. These readings are historical, refresh daily after market close, and are not investment advice.
With $9.9M in cash and $117K in debt, CLIR maintains more liquidity than leverage. This favorable balance sheet position can be an asset when capital markets become less accommodating. The company is burning cash, with free cash flow at -$4.7M. This typically occurs when a company is investing aggressively in growth, but sustained cash burn can strain the balance sheet. ROE of -51.7% points to negative capital efficiency, indicating how much profit the company produces per dollar of shareholder equity. Revenue has grown from $374K (2022) to $5.2M (2025), reflecting a 1299% increase over the period.
With cash comfortably exceeding debt, CLIR has financial flexibility that may help navigate uncertain periods. Negative free cash flow means the company is currently spending more than it generates, which may require future fundraising or debt if the trend continues. Understanding these risk dimensions helps frame what to watch going forward as conditions evolve for ClearSign Technologies Corporation and its sector.
