Here "weigh" is a metaphor. You should have noticed the word "against" later on.

Literally, one weighs one thing against another thing on a scale.

here is a picture of a scale (I hope you can see it)



To weigh two things against each other, you put one in each pan. The pan holding the heavier thing will be the lower one.

Metaphorically, one can "weigh" two ideas or abstract concepts. One compares them. Investors had to decide between:

(1) Their fears that losses in the American mortgage market would get worse.
(2) Their faith that a strong global economy would recover.

Investors had to "weigh" [decide, evaluate] whether [in their opinion based on knowledge and information available], (1) or (2) was more likely.

When my son asked me if he could go camping in the forest, I had to weigh my fears for his safety against my trust in his maturity and good sense.

What does "American mortgage markest" mean?[/quote]

In America, and other Western countries, there is a "market" in mortgages and other loans. If you borrow money from a bank to buy a house, promising to pay it back over a period of time, that bank may sell all or part of the debt to another instititution or to individual investors. The aggregate of all such transactions is the "market". When people do not think that mortgages are a good form of investment, then there may be a crisis in the mortgage market. There is one at the moment.

Unfortunately, Miss L Toad is a "troll" who has answered your question with nonsense, for his or own childish amusement. You should disregard further posts from this person.

Contex,
I thank you very much for your patient explanation to this question and all other questions I asked before.

Un huh. The nonsense answers are all well and good on the nonsense threads.
