Industry: The worry about the imbalance between supply and demand still exists, and there is limited room for alumina futures to continue to fall. Since the intraday record of 5,540 yuan/ton on December 5, the main contract price of domestic alumina futures has started to fluctuate and fall, reaching a minimum of 5,077 yuan/ton on December 12, with the cumulative maximum decline exceeding 8%. According to industry insiders, the increase of alumina registered delivery brands and the sharp drop in overseas alumina spot quotations have led to the recent decline in alumina futures prices. Although the short-term news in the market is intertwined, the imbalance between supply and demand in the alumina market has not fundamentally improved, so there is limited room for the subsequent decline of alumina futures prices.

["Shanghai housing subsidy of 300,000 yuan" and "down payment of 20,000 yuan for 1.8 million hardcover existing houses"? Rumor has come] Recently, there have been a number of housing advertisements on the short video platform. The agent who released the housing claimed that he could receive the "housing subsidy" when buying a house in Shanghai, with the amount ranging from 200,000 yuan to 300,000 yuan. An intermediary declared: "Shanghai Songjiang New Town has a total price of 760,000 yuan and a housing subsidy of 250,000 yuan." "After receiving the subsidy, you can buy a 78-square-meter house with a down payment of 50,000 yuan." There is also an intermediary who claims: "The minimum payment can be only 20,000 yuan, and you can buy a finely decorated existing house with a total price of 1.8 million yuan." The reporter consulted a number of intermediaries and learned that the so-called "purchase subsidies" appearing in short videos are not government subsidies, but gimmicks. When the house-watchers consult subsidies on the spot, different intermediaries will have different calibers. Usually, there are three routines-one is to raise the price first and then lower the price. Second, the so-called "subsidy" is actually that developers lend money to buyers to pay down payment, and buyers have to pay interest. Third, the commission returned by the intermediary to the buyers is packaged as a "subsidy".
