问题如下：
Comparison of a company’s financial results to other peer companies for the same time period is called:
选项：
A.technical analysis.
B.time-series analysis.
C.cross-sectional analysis.
解释：
C is correct.
Cross-sectional analysis involves the comparison of companies with each other for the same time period. Technical analysis uses price and volume data as the basis for investment decisions. Time-series or trend analysis is the comparison of financial data across different time periods.
解析：cross-sectional analysis是横向比较同一时期不同公司的数据，time-series analysis时间序列分析或者trend analysis是比较同一公司不同时期的数据，technical analysis技术分析以市场价量信息为基础来判断股票等金融商品的趋势以做出交易决策。
C选项的意思是横截面分析吗？
