It's a surprise that investors felt like buying after Tuesday's market action, according to CNBC's Jim Cramer.
In a CNBC special report Wednesday night, Cramer said "the psychology had changed" as equities markets snapped a six-day losing streak.
"I was actually astonished this morning that more people weren't disheartened by what happened yesterday—the buyers came right in again," he said.
In addition to Chinese easing and dovish Fed comments, Cramer said that the financial sector "looking great" gave investors a reason for optimism.
But investors may still be worried, with many citing China as their chief concern.
Liz Ann Sonders, chief investment strategist at Charles Schwab, described the market turmoil as "a period where there was just a tremendous amount of uncertainty and maybe lack of confidence in central banks." She characterized China's recent moves as simply "a straw" that launched the major bout of selling.
