Answer:
The strategy is called sector-wise diversification.
Explanation:
This is an excellent way to diversify and distribute the risk as if we only invest in companies in one sector of the economy, if that sector is affected by poor economic conditions, the companies in that sector will under perform and the entire portfolio will go down in value.
However, if we diversify the risk among different sectors such as agriculture, consumer goods, banks and financial services, diversified holdings, food and beverages, etc.. even if a sector falls under difficult times, the rest of the portfolio will only be slightly affected,
