IBM stock soars pre-market as growth in software business boosts share price.

IBM's pre-market trading surged by over 8%, after the company announced revenue growth and continued expansion of its artificial intelligence business. Analysts at JPMorgan Chase pointed out that the company's software department is the main driver of revenue growth, and strong performance expectations reflect the growth momentum of IBM's full product line. Better-than-expected free cash flow and profit growth are also optimistic signals, while layoffs are helping to protect profit margins. However, analysts also warn that growth in the hybrid cloud division is slowing down, and infrastructure business revenue is expected to decline. Additionally, the consulting department is facing both intense competition and demand threats.
