Core Views - For stock index futures, it is speculated that the deep discount of small - cap stock indices recently is 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. It is recommended to go long on the economy, and it is advisable to allocate IF, IC, IM forward contracts on dips. 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 [2]. - For treasury bond futures, although the current spot bonds show a pattern of strong supply and weak demand, this pattern is expected to change in the future. The government bond net supply rhythm may slow down in June, the long - term liability cost of insurance may be lowered in July, and the domestic market risk preference has returned to a defensive style, which may increase the demand for bond market allocation. It is recommended to go long in the short - term and short in the long - term, buy T and TL contracts on dips in the short - term, and hedge T and TL contracts on rallies in the long - term [3]. 3.
