问题如下：
Why is technical analysis especially useful in the analysis of commodities and currencies?选项：
A.Valuation models cannot be used to determine fundamental intrinsic value for these securities. B.Government regulators are more likely to intervene in these markets. C.These types of securities display clearer trends than equities and bonds do.解释：
Commodities and currencies do not have underlying financial statements or an income stream; thus, fundamental analysis is useless in determining theoretical values for them or whether they are over- or undervalued.a选项只能说明大宗商品不易估值，并不能说明它就适合技术分析。是因为趋势性的存在，才是技术分析适用的依据。c选项不对么？
