Financial risk observations and what to check
These are saved observations about business performance, not predictions. Review the company filings alongside the interpretation below. Latest stored financial period end: 2026-06-27.
Total debt increased 134.2% versus the same quarter last year.
Compare the added borrowing with available cash, cash generation and maturities. A percentage increase from a small starting balance can look large without measuring the full debt burden.

Momentum & Volatility Signals
Two different market-behavior signals. Momentum measures direction and trend strength. Volatility measures how large and unstable the price moves are, regardless of direction.
Building upward momentum
Low movement
A high momentum score means price has been trending upward with confirming short- and medium-term strength. A low score means downward or weakening momentum.
A high volatility score means larger, less stable price swings. It can happen while a stock is rising or falling, so high volatility is not automatically bullish or bearish.
Important: the volatility score above is based on realized price volatility. Implied volatility (IV) comes from options prices and represents the market's expected future movement. Wall Street Score will keep IV separate and will only display it when a verified options-chain feed is available.
