I don't think you understand how the word "delayed" works.
It sort of requires that there be an original point in time, and there has not been one. Nor has there been any reason to assume one, as MTG (as with many insurance companies) always report near the very end of the month and later than most bellweathers, bluechips, etc, and have done so for quite some time.
Frankly I think it's #$%$ I am embarassed for MGIC. Get it together. Earnings should be released. They are notorious for releasing late late. I have seen releases near 7pm sometimes. You would think if good news it would be released this morning... bad new late on a friday. I am disillusioned!!
MGIC did not publish any earning release in their website, why are you expecting one. Paid and Edi is right there is no release announcement. My hunts is MGIC maybe waiting for Freddie's decision on how to settle the dispute, so it is one release weather it is bad or good. I wish it is good. I do not know where these brokers and yahoo finance get the date of release which is not true.
