Narrative:

Climbing we were assigned 10;000 feet at 7;000 FMA said altitude due to the fast climb and turbulence. Passing 8;000 feet ATC reassigned to level off at 9;000 feet; but airplane was slow to capture altitude of 9;000 feet due to high climb rate and turbulence; moderate; and after passing 9;300 feet I disconnected the a/P and a/T and stopped climb at 9;600 feet and was correcting back to 9;000 feet when ATC noticed we had passed 9;000 feet and issued climb to 10;000 feet. ATC was step climbing us due to aircraft in front. No TA or RA or ATC immediate commands were generated. Due to moderate turbulence and high v/s climb I did not feel the need to over aggressively correct the altitude back to 9;000 feet and risk injuring a flight attendant or passenger; knowing clearly that the step climb was due to traffic ahead we were outperforming. Flight continued safely and uneventfully.

Title: Air Carrier flight crew reported over shooting an altitude during departure.

Narrative: Climbing we were assigned 10;000 feet at 7;000 FMA said ALT due to the fast climb and turbulence. Passing 8;000 feet ATC reassigned to level off at 9;000 feet; but airplane was slow to capture ALT of 9;000 feet due to high climb rate and turbulence; moderate; and after passing 9;300 feet I disconnected the A/P and A/T and stopped climb at 9;600 feet and was correcting back to 9;000 feet when ATC noticed we had passed 9;000 feet and issued climb to 10;000 feet. ATC was step climbing us due to aircraft in front. No TA or RA or ATC immediate commands were generated. Due to moderate turbulence and high v/s climb I did not feel the need to over aggressively correct the altitude back to 9;000 feet and risk injuring a FA or passenger; knowing clearly that the step climb was due to traffic ahead we were outperforming. Flight continued safely and uneventfully.
