According to the latest research from SDIC Securities' strategy team, the fundamentals of A-shares continue to improve, with the profit growth rate of all A-share non-financial companies returning to double-digit growth in the first half of 2026 for the first time since 2021. Technology and "going global" are leading a new profit cycle. The report innovatively proposes a "capital expenditure and profit growth difference - second derivative of profit - net profit margin" three-factor valuation model for economic prosperity. It analyzes that sub-sectors such as semiconductors, communication equipment, consumer electronics, gaming, and batteries are currently in a "double-click main ascent" phase, with AI hardware and "going global" being the core intersection, and fundamental selling signals are still far off. From a macro structural perspective, excluding financials, the profit contribution from technology and "going global" has approached 50%, nearing the critical point for triggering a new upward profit cycle. Among these, the net profit growth rate for semiconductors rose from 167% in Q1 2026 to 236% in H1 2026, with a single-quarter growth of 279% in Q2, and the net profit margin significantly rebounded to 19.1%.
