The futures-spot price difference remained at a low level [3]. Trading Strategy - Recently, small-cap stock indices have had a deep discount, presumably due to the expansion of neutral product scale since this year. As the bond bull market has not restarted, the proportion of short positions in neutral products may still be high, so the deep discount may continue, leading to market fluctuations. A short-term band strategy is recommended [3]. - In the medium to long term, the report maintains a bullish view on the economy. Buying IF, IC, and IM forward contracts on dips is recommended. For near-month contracts, there is a risk of a decline in micro-cap stocks, which may drag down the IC and IM indices, so caution is advised [3].

Trading Strategy - The cash bond market has recently shown a pattern of strong supply and weak demand, but this pattern is expected to change. First, the maturity scale of government bonds in June has increased, and the net supply rhythm of government bonds may become more stable. Second, there is a possibility that the long-term liability cost of insurance companies will be lowered in July. Third, the domestic market risk preference has returned to a defensive style, and the allocation demand for the bond market may increase [5]. - For futures, the CTD bond price of the near-month contracts is low, and the recent IRR level is high, so short sellers have a strong willingness to deliver, putting pressure on the near-month contract prices and causing the far-month contracts to have a premium. The positions of T and TL have increased, while the positions of TF and TS have decreased, indicating strong long positions at the long end, possibly betting on a further decline in future policy interest rates. It is recommended to be short-term long and long-term short, buying T and TL on dips in the short term and hedging T and TL on rallies in the long term [5]. Economic Data - High-frequency data shows that the recent import and export sentiment has rebounded [12].
