How are a bear market and a bull market different?

A bear market indicates a strong economy and a bull market indicates a coming recession.

A bear market refers to stocks and a bull market refers to bonds.

In a bear market investors are limited to stocks in the S&P 500, and in a bull market there are no limits.

In a bear market stock prices decrease, and in a bull market stock prices increase.

"In a bear market stock prices decrease, and in a bull market stock prices increase" Is the correct answer.

89.7%

Explanation:

Percentage yield is the ratio of the actual yield of a product to the theoretical yield of a product  expressed as a percentage.

Percentage yield =  x 100

Given,

Actual yield of a product = 2.80 g

Theoretical yield of a product = 3.12 g

Percentage yield =  x 100 = 89.7 %
