Help me with this economics question involving stocks?

1. Giving a brief explanation, determine the likely effect of each of the following on the value of GM stock.(Consider each event independent of the others.)

a. The Federal Reserve lowers both the "discount" rate and the Federal Fund rate.

b. The rising unemployment rate signals a slow-down in the economy.

c. The value of the US dollar has significantly gone up against most currencies, making American products more expensive to foreigners while making imports cost less to American consumers.

d. The United States signs a free trade agreement with European Union.

e. Ford Company reaches an agreement with the auto workers union.

f. It has been reported that there are signs that the European recessions is coming to an end.

It will stimulate the stock market because the bond yield has been reduced because of that policy. The rising unemployment rate will slow down the FED to raise the rate again. If so the dollar will flow out of the country to the emerging markets. Dollar will be weak.
