I've been watching, researching, and holding Shandong Hi-Speed stock for four years. The core logic is that the province's expressways are basically built, so there's no need for large capital investment, and with continuous cash inflow, the stock price can gradually rise. In fact, any industry is more or less the same—when a company is rapidly expanding, the stock price often doesn't rise much; it's when the business stabilizes and generates steady cash flow that the stock has the confidence for a long-term bull run.
