Why It Matters
Which of these 2 stories sounds closer for this stock?
1. Generates cash flow
The stock generated 4% or more of the share price (called cash flow yield), and shows moderate 10-15% or more growth.
2. Riding a trend
Think Tesla during the pandemic of 2020 when EVs were riding a cultural high, or Nvidia in the current AI boom, or even Figma.

Why The Stock Moved
Qualitative Assessment
AI Generated Analysis | Feedback
Here are the key points explaining the -22.2% stock movement for Byrna Technologies (BYRN) from approximately July 31, 2025, to November 15, 2025:
1. Significant Decrease in Cash and Marketable Securities.
Byrna Technologies' cash, cash equivalents, and marketable securities decreased from $25.7 million at November 30, 2024, to $9.0 million at August 31, 2025. This substantial reduction in liquid assets, attributed to working capital changes, could have raised investor concerns about the company's liquidity position.
2. Increase in Inventory and Accounts Receivable.
The company experienced a considerable increase in inventory, which totaled $34.1 million at August 31, 2025, up from $20 million at November 30, 2024. Accounts receivable also rose to $8.9 million from $2.6 million in the same period. While these increases were noted as strategic builds for the holiday season and new product launches, they tie up capital and could be perceived as a risk if sales do not meet expectations or if collection of receivables slows.
