Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Assured Guaranty (NYSE: AGO ) shared were down 10% Monday after the company lost its AAA rating.
So what: S&P downgraded Assured Guaranty from AAA to AA on higher potential losses because of mortgage-backed securities. Later in the day, the company announced it would beat analysts' estimates of earnings in the quarter.
Now what: This is a double-edged sword for investors as the higher guidance is great in the short-term but a lower rating hurts the company's prospects going forward. Ambac Financial (NYSE: ABK ) and MBIA (NYSE: MBI ) have been hurt by ratings downgrades, and Assured Guaranty was one of the last standing AAA-rated insurers. The market didn't seem to be too excited about the guidance news later in the day, so I think this will be a long-term worry for shareholders going forward.
