The present article is devoted to consideration of investment strategy in stock market. The questions connected with designing of such strategy are systemically considered in it. The emphasis is thus placed on adaptation of the general (managerial) theory of engineering to engineering of investment strategy. Engineering of investment strategy is considered in indissoluble interrelation with the analysis of their typology. The most actual types and directions of engineering of investment strategy are characterized in the conclusion of article.
The article gives an overview of influence of stock market discrimination on market value of companies in China. There are two types of shares on Chinese stock market: class A shares, which are available for domestic investors, and class B shares, which are available for foreign investors. Such market structure is not a unique Chinese market's feature. It is also used in such countries as Finland, Singapore, Switzerland, Thailand, etc. What differs Chinese market from markets with similar structure is the fact that class B shares are traded with substantial discount to class A shares. Such a situation is explained by such factors informational asymmetry between domestic and foreign investors; different liquidity of different classes of shares; diversification effect, connected with investment in Chinese stock market; size of companies; ratio of amounts of shares of different classes; stock exchange where company's shares are traded.

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
