Shell Index refers to the house price index calculated by Shell Housing based on big data analysis and algorithmic modeling. It is based on the statistics and analysis of the massive housing information and transaction data on the Shell Housing platform. Shell index can better reflect the current trend and change of housing prices in the city or region.

However, it should be noted that the Shell Index is only a reference. The rise and fall of house prices are affected by many factors, including supply and demand, economic situation, policy regulation and so on. Shell index can only provide a relative trend of house price, for specific house price prediction and investment decision also need to consider other factors.

In addition, the accuracy of Shell Index is also related to the authenticity and completeness of the data. If the data collection is incomplete or biased, then the accuracy of the Shell Index will also be affected. Therefore, when using the Shell Index, you need to identify the source and quality of the data and combine it with other information to make a judgment.

In summary, the Shell Index provides a reference, but cannot fully and accurately predict home price trends. When making home purchase or investment decisions, it is recommended to consider all factors and seek advice from professionals or organizations.
