The domestic steel index composite index reported 143.52 points


On February 13, the domestic steel index composite index reported 143.52 points, down 0.04% from the previous trading day. Among them, the rebar index reported 158.84 points, an increase of 0.16% from the previous trading day; the hot coil index reported 136.79 points, a decrease of 0.45% from the previous trading day.
At present, although the futures market has continued to fall, the overall mentality is relatively stable due to the low inventory levels of merchants.
According to market feedback, there is currently a certain amount of financial pressure in some of the finished steel trade links, while the billet trade link has a weak willingness to ship at a low price, and it is more cautious to wait and see. The manufacturers generally pay attention to the changes in the construction steel stocks in the southern market. It is predicted that the billet prices will be steady and weaker tomorrow.
In terms of variety and spot, affected by the early morning price increase, the market quotation increased slightly, and the transaction volume was slightly increased. At present, the downstream demand is gradually increased, and the steel market cost support is obvious, and the inventory risk is not large. After the recovery, prices will rise easily but not fall.
In the short term, affected by the inventory and supply side, the bottom of the billet is supported, and the upward movement is temporarily controlled by the release of demand. The current rise and fall are more affected by the main contract and mentality.
In terms of variety and spot, due to the impact of the decline in early trading futures, market quotations fell slightly. Although individual markets gradually recovered, the continuous rain in the south led to slower procurement progress and greater market pressure. The price formed a support; it is expected that the steel plate price will still fluctuate widely tomorrow, and the spot market is still weak.
In terms of variety and spot, affected by the changes in the strength of the futures market, long products are still weakly down, the plate has slightly increased, and the market turnover has decreased slightly compared with yesterday. After the Lantern Festival, there may be a start of work tide, which may be beneficial to steel prices; The factory resumed work slowly, the customs clearance process of imported coal was blocked, and the coke stocks of steel mills continued to degrade, which supported the prices. It is expected that the steel plate prices will continue to fluctuate within a narrow range tomorrow, and the spot market will continue to consolidate.
In the evening, the billet prices in Tangshan fell by 40 to 3480 yuan / ton.
The overall price of the spot market has declined slightly, and the overall transaction is still sporadic due to the fact that demand has not yet been released, but it is slightly better than yesterday.
In the short term, the price of the steel market is affected by the fall in the futures market, and it is difficult to increase, but under the vacuum period of transaction, the price decline is also limited.
