Axon Enterprises has reported strong Q3 earnings with record revenue and net income, driven by growth in its Taser business and software. The stock has reached $600 per share, reflecting the company's robust financial performance. However, the high valuation of the stock suggests that it may not be the best time to buy, but rather to hold. The potential of Axon's AI tools and international expansion opportunities support long-term growth, balancing the high valuation.
