I would disagree. I know a variety of socialists and there are a large number of values that underpin their beliefs and are considered a foundation for the particular brand of political discourse.

I would not hesitate for a moment to call these "traditional values."

The sorts of values that socialists traditionally have? Socialists have been around in strength for over a century, and there're certain values that they tend to have, and tend to have had.

That list is slightly diluted, however, with the values of my idealised-socialist, who holds the socialist beliefs I find most credible.
