Ann: Moodys affirms credit rating, page-3

This is generally positive, but in each positive it depends on the expectation.

i.e. if they were expecting a moodys rating upgrade, then this is negative.

If they were expecting an affirmation its neutral (delivered as expected).

If they were anticipating a downgrade due to asset to debt ratio, then this is positive.

I may have over simpified this, but the market tends to react more based on expectations rather than outcomes and others can explain in more depth than I can.
