Main views of overseas markets in a week: the global market volatility has further intensified this week. Intraday fluctuations in the US stock market rose for several trading days this week. From the perspective of information technology industry, apple, Seagate technology, HP, IBM, American online storage, Zhanbo network, Texas Instruments, arista network, Qualcomm, gaozhite technology, Huihe and other companies have increased too much in a short period of time, and there has not been a full correction; From the perspective of non essential consumption, Lloyd's, target, Ford, O'Reilly, carrier global, Auto Zone, dollar tree, tractor supply, leading auto parts, epex and other early cumulative increases in a short time have not been fully corrected; In biotechnology, the cumulative increase of United Health Group, Pfizer pharmaceutical, Alberta, anthem, Maxon, Mayuan Bergen and Senna in a short period of time has not been fully corrected; Among industrial stocks, UPS, United The Pacific Securities Co.Ltd(601099) , Raytheon technology, Deere, Eaton, general dynamics, Johnson Controls, Parker Hannifin, Republican waste disposal, gu'anjie, Robinson global logistics and Robert Haff have not fully corrected in a short period of time; Among the financial stocks, berkshire-b, Bank of America, Wells Fargo, Morgan Stanley, Carson wealth management, PNC Financial Services, Qianjin insurance, metropolitan life, Bank of New York Mellon, Prudential finance, traveler group, Arthur Gallagher, may third bank, corkay international, citizen finance, Lianxin bank, Chion bank The cumulative increase of people's United finance in a short period of time has not been fully corrected. It is expected that there will still be room for valuation correction in the future for those information technology stocks, biotechnology stocks, industrial stocks and financial stocks that have increased too much in the early stage and have not yet been fully corrected. In addition, in the U.S. stock real estate industry, the short-term growth of Efron Bay community, fair housing, Essex trust, kink real estate, MAA real estate trust, Ambo and Volkswagen warehousing trust is too large and has not been fully released from valuation risk; It is expected that there will still be pressure for adjustment in the future. In the U.S. stock defense industry, essential consumer stocks such as Procter & Gamble, Coca Cola, Pepsi, Colgate, Yizi international, Archer Daniels Midland, general mills and Hershey, as well as utility stocks such as southern power, exlon power, Edison United Electric and nissos, rose sharply; The defensive stocks of US stocks that accelerated the rise in the early stage in the future may have a certain correction. Considering the tightening monetary policy of the Federal Reserve and the high valuation of US stocks, it is expected that the US stock market has not stabilized at this stage. In view of the greater linkage between the European market and US stocks, there may still be callback pressure in the European market for some time in the future. Considering that the Fed is in the early stage of tightening monetary liquidity, it is expected that overseas emerging markets such as Southeast Asia, Latin America and Middle East Africa will still fall further in the future. From the perspective of Hong Kong stock market, the resilience of Hang Seng Index and Hang Seng China Enterprise Index in Hong Kong stock market this week is significantly better than that of Hang Seng technology index. Considering that the Hong Kong stock market has experienced a significant adjustment last year, so the price and valuation risks have been significantly released, it may be difficult for the Hong Kong stock market to fluctuate sharply at this stage. Considering that the world is in an economic cycle with high inflation, Hang Seng's essential consumer industry may have some resilience. In addition, considering the support of policies, Hang Seng H-share financial industry and Hong Kong construction and engineering index may have some room for rise in the medium term.
