问题如下：
"Market participants believe that the historical patterns in the price data have a tendency to repeat. These price patterns repeat because market prices reflect human behavior. Therefore, there is no need to exploit risk factors such as inflation and interest rate."
The above statement describes the active currency approach of:
选项：
A.volatility trading
B.technical analysis
C.economic fundamental
解释：
B is correct.
考点： active currency management的方法
解析：四种方法分别是economic fundamental, technical analysis, carry trade, volatility trading.这段陈述是关于技术分析法的，可以抓关键词，historical patterns…repeat，描述的是根据历史数据的规律抓住主动管理的机会。同时还描述说这些价格形态反映了人的行为，根据行为金融学的理论，市场有momentum（惯性）就是人们有追涨杀跌的心理，所以涨的股票会交易量增加，价格也会持续上涨，分析师可以通过价量分析找到主动管理的机会，价量分析就是技术分析法。
请问如何理解题中“there is no need to exploit risk factors such as inflation and interest rate”这句话？
