Relative strength analysis typically compares the performance of an asset with that of a benchmark or other security using a:

选项：

bar chart that reflects the two assets’ price history.

line chart that reflects the ratio of the two assets’ prices.

candlestick chart that reflects ratios measuring the magnitude of each asset’s up days versus down days.

解释：

B is correct.

In relative strength analysis, the analyst typically prepares a line chart of the ratio of the two assets’ prices, with the asset under analysis as the numerator and with the benchmark or other security as the denominator. With this single line chart, the analyst can readily visualize relative performance by the positive or negative slope of the line. A rising line shows the asset is performing better than the index or other stock; a declining line shows the opposite.
