Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report In the third week of December, year - end food prices continued to rise, the operating rate continued to decline, and real estate sales started the year - end sprint, but the slope was significantly lower than that of last year. In terms of inflation, the increase in the food price index narrowed, and the decline in pork prices widened. In terms of exports, container shipping prices continued a slight increase, mainly boosted by the year - end signing season. In terms of investment, cement prices increased slightly for three consecutive weeks, mainly due to rising demand and price hikes in the central and southern regions, while demand in other regions remained weak. The apparent demand for building materials and rebar improved slightly. In the real estate sector, both new and second - hand housing sales increased month - on - month, and the year - end sprint slope may be similar to the rhythm of 2023. For the bond market, the economic data in November showed a continued decline in momentum, but the bond market was insensitive. There may be certain expectations for the "good start" in the first quarter of next year. In the short term, potential disturbances to the bond market sentiment such as the new regulations on fund fees still exist, but as the cross - year allocation window approaches, some allocation funds have begun to enter the market gradually. Looking forward to 2026, fiscal and macro - policies may continue to be implemented earlier, and the probability of a "good start" in data is relatively high, which may jointly suppress sentiment. Especially with the base adjustment in 2026, the inflation performance in the first quarter may further affect expectations and requires careful observation [3][37].

Report Industry Investment Rating - The report does not provide an industry investment rating. Core Viewpoints - Referring to the experience of Japan and South Korea during their technology transformation phases, the technology bull market did not significantly impact the bond market. Bond investors need not overly worry about the ongoing technology bull market in the equity market. The linkage between stock and bond markets is more of a short - term factor, and long - term bond market pricing should still consider fundamental factors [1][3][31]. Summary According to the Table of Contents 1. Overseas Experience of the Impact of the Technology Stock Bull Market on the Bond Market Japan: From "Trade - Oriented" to "Technology - Oriented" - After World War II, Japan implemented a "trade - oriented" economic strategy, achieving relatively high economic growth from 1956 - 1973. In the 1970s, due to the loss of labor dividends and the oil crisis, Japan shifted towards a technology - oriented economy [1][10]. - The government introduced a series of policies to support high - tech industries. The VLSI plan promoted the development of the semiconductor industry, leading to a technology stock bull market. From 1970 - 1985, the Nikkei 225 index rose from about 2300 to about 13000, and the information and communication industry index reached 31.75 in 1985, compared to 1 in January 1970 [13][14]. - From 1975 - 1985, the Japanese bond market was highly volatile, mainly due to the two oil crises in 1973 and 1980. The bond yield changed with inflation and policy interest rates, and the stock - bond seesaw effect was not significant. After 1980, there was a period of stock - bond double - bull [18]. South Korea: Comprehensive Promotion of Technology Transformation - South Korea's economic transformation was similar to Japan's, gradually shifting from labor - intensive to capital - intensive and then to technology - intensive. In 1986, it proposed a technology - oriented strategy and launched a series of plans to support high - tech industries [2][23]. - After 1986, the South Korean stock market entered two accelerated growth periods. In the first half of 1997, the stock market rebounded, led by the electrical and electronic equipment industry, while the national bond yield remained stable or declined, showing a simultaneous strengthening of stock and bond markets [2][26]. Comparison with China - China is currently in an important economic transformation stage, with the economic growth engine shifting from traditional industries to emerging industries, and the role of consumption in driving domestic demand increasing. China has formed a technology - led equity market bullish atmosphere [3][29]. - Similar to Japan and South Korea, the linkage between the stock and bond markets in China may be limited. The stock - bond seesaw effect in the third quarter was likely due to short - term factors, and the long - term bond market pricing depends on fundamental and policy factors [3][30].
