Cramer on Monday said a number of regional bank upgrades today were “all about real estate,” specifically the commercial kind.

Cramer said that Regions Financial , Zions Bancorp and Fifth Third , among others, earned a thumbs-up from Deutsche Bank, and largely because of what looks like a bottom in commercial real estate. Many analysts had said the industry would crash, and those predictions had weighed on the market. But with that option seemingly no longer on the table – and Principal Financial Group and Lincoln National have said as much, Cramer pointed out – investors have one less variable about which to worry.
