The concept of states of financial markets based on correlations has gained\nincreasing attention during the last 10 years. We propose to retrace some\nimportant steps up to 2018, and then give a more detailed view of recent\ndevelopments that attempt to make the use of this more practical. Finally, we\ntry to give a glimpse to the future proposing the analysis of trajectories in\ncorrelation matrix space directly or in terms of symbolic dynamics as well as\nattempts to analyze the clusters that make up the states in a random matrix\ncontext.\n
