Quality & Screener
AI Rating
–Not yet rated — we only show a category once an SEC-backed file with at least two cited passages is available. How the Rating Is Built
Highlighted are things our editorial team noticed: green = stands out as strong, red = deserves a closer look. No single metric is a verdict on its own — always read it in context.
Analysts & Price Target
The price target sits 252.1% above the current price.
Combined picture of the price targets and recommendations of every analyst covering the stock. Price targets are expectations for the next 12 months, not promises — and they often follow the price rather than predict it.

- EPS (Earnings Per Share):
- Quarterly profit divided by the total share count — how much of the profit works out to a single share.
- YoY (Year over Year):
- Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
- Sales:
- All revenue for the quarter, before any costs are deducted — the top line of the income statement.
- Net Margin:
- What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
- OCF (Operating Cash Flow):
- The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
- FCF (Free Cash Flow):
- Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.
