Bold Move is one of Dante's special moves, where he performs a forward flip which is special cancellable (possibly based on his home series' jump cancel mechanic). This is usually used for Bold Cancelling which involves cancelling Stinger into this move into one of Dante's Special/Hyper Moves.
Bold Cancelling Tip[]
To Bold Cancel from Stinger to special, you must press 
+
before Stinger hits your opponents while they are guarding or not. Once Stinger is hit after + before hit, you can cancel to other special/hyper moves before the it goes to Bold Jumping.
Example:
+
(press + before Stinger hits) > (once Stinger is hit, and + was used before Stinger hits) 
+
