Let $$f(x)=a_n x^n + a_{n-1} x^{n-1} + \cdots +a_1 x +a_0$$ be a polynomial with real positive coefficients and $$p\in \mathbb {R}$$ . The pth Hadamard power of f is the polynomial $$f^{[p]}(x):=a_n^p x^n + a_{n-1}^p x^{n-1}+ \cdots + a_1^p x +a_0^p$$ . We give sufficient conditions for $$f^{[p]}$$ to be a Hurwitz polynomial (i.e., to be a stable polynomial) for all $$p>p_0$$ or $$p
