Unlike last week, this week's IPOs came out with a bang. Enterprise software data company Splunk saw returns of 108.7% on opening day and luxury luggage and travel-goods maker Tumi Holdings returned 47.0% by the closing bell.

On Tuesday, SandRidge Mississippian Trust II and Digital Cinema Destinations managed to close in the green, up 3.57% and 5.57%, respectively.

Has investors' appetite for IPOs changed drastically from last week -- when nearly all names closed in the red -- or are these companies simply more promising?
