单选题-Supposing there are two stocks in a market index:Company X has 50 shares valued at $2 each.Company Y has 10 shares valued at $10 each.When the index started the price weighted index calculated out to $6, and the value-weighted index was 1.Nothing has changed except now the price of Company X's stock is selling for $4 per share. What is the price-weighted index and what is the value-weighted index?

单选题

A.

B.

C.

我个人认为这个应该是：B

解析：Price weight = [(4) + (10)] / 2 = 7,
Value weight = [(4)×(50) + (10)×(10)]/ [(2)×(50) + (10)×(10)]×(100) = 150.
