Summary by Directory 3.1 Stock Market Characteristics - This week (from February 2, 2026, to February 6, 2026), the bond market strengthened overall driven by risk - aversion sentiment, and the yield of ultra - long credit bonds showed a slight downward trend. Compared with last week, the number of outstanding ultra - long credit bonds with a yield of 2.4% - 2.5% increased to 388 [2][13] 3.2 Primary Issuance Situation - The subscription sentiment for new ultra - long credit bonds increased this week. The total supply of new ultra - long credit bonds was 3.1 billion, and the supply volume shrank to a relatively low level in the past two years. The interest rate of new ultra - long urban investment bonds continued to decline to 2.58%, and the interest rate of new ultra - long industrial bonds remained around 2.5%.

This week, the bond market sentiment continued to recover. Treasury bonds with a term of over 10 years performed well, with the full - price index rising nearly 0.5% weekly. The prices of ultra - long credit bonds also increased marginally. The full - price indices of AA+ credit bonds with terms of 7 - 10 years and over 10 years increased by 0.04% and 0.17% respectively compared with the previous week, outperforming medium - short - term credit bonds and secondary capital bonds [4][30] - The trading sentiment of ultra - long credit bonds was weak. Although long - term bonds led the rally this week, in terms of liquidity, the number of transactions of general credit bonds with a term of over 7 years slightly increased to 275, and the activity did not improve significantly. Investors were concerned about chasing up ultra - long credit bonds due to insufficient spread protection (the spread between 7 - 10 - year industrial bonds and 20 - 30 - year treasury bonds was only 13bp) and potential supply pressure [4][33] - This week, ultra - long credit bonds were mostly traded at a lower valuation. However, in terms of buying willingness, the proportion of TKN for varieties over 10 years decreased significantly, indicating limited enthusiasm for chasing long - term bonds in the market [4][39] - In terms of investor structure, the allocation sentiment of trading desks such as public funds towards ultra - long credit bonds became more cautious, and the net buying volume decreased month - on - month. The buying power of insurance and other funds for long - duration assets also weakened temporarily. Overall, ultra - long credit bonds lacked continuous and sufficient buying support [4][44] - From a more microscopic perspective, due to the faster decline in long - term treasury bond interest rates, the spread between active ultra - long credit bonds and treasury bonds of similar terms widened passively this week. Looking ahead, the pre - holiday asset shortage logic continues, and the continuous opening of amortized cost method bond funds will provide incremental funds for corresponding term varieties. However, looking after the holiday, the extremely low pricing of current ultra - long bonds is relatively fragile, and factors such as the recovery of the stock market, the increase in government bond supply, and unexpected policies may cause price fluctuations of ultra - long credit bonds [5][46]
