Appears in These Scanners

This stock currently matches 6 of our scanner strategies — each hit links to the scanner.

Only genuine hits from verified scanners count; pure ranking metrics (P/E, P/S, and similar, which just sort the whole universe) don't count as a hit. Scanners marked in red are red-flag signals (risk/short scanners) — appearing there is not a seal of approval. View all scanners

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.

What Do These Terms Mean?
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.
