The industry ratings present an overview of the market and take into account a limited number of parameters. Expert reviews help to assess the situation more deeply. PIK lost first place in terms of revenue in the third quarter. However, if we take into account the result of the subsidiary Topas, it will remain the leader with a result of 43.1 billion rubles. But given the absolute dependence on mortgage interest rates, these figures do not indicate the stability of the company. The greatest stability is observed in the premiums industry, which does not depend on the credit terms. If we study the ranking from the point of view of operational efficiency, Donstroy will have the highest index. With the same level of income as PIK and MR Group (~30 billion rubles), the developer achieved the highest average cost of a lot - 57.5 million rubles, having completed 492 DDUs during the quarter. The strategy to increase margins makes the company more resistant to fluctuations in the banking sector.
