Let $X$ be a $\text{CW}$ complex with a continuous action of a topological group $G$ . We show that if $X$ is equivariantly formal for singular cohomology with coefficients in some field $\Bbbk $ , then so are all symmetric products of $X$ and in fact all its $\Gamma $ -products. In particular, symmetric products of quasi-projective $\text{M}$ -varieties are again $\text{M}$ -varieties. This generalizes a result by Biswas and D’Mello about symmetric products of $\text{M}$ -curves. We also discuss several related questions.
