Stability constant of complexes
As $K$ is a thermodynamic constant, and if you define your reaction as 

$A + B \rightarrow{} C + D$

leading to 

$K = \frac{c_C \cdot{} c_D}{c_A \cdot{}c_B}$

then -- thermodynamically -- yes.  Especially for chelate complexes (like with EDTA), entropically favoured. This answer excludes (macroscopic) kinetics
