Markets have inertia, just because a good news comes up this is not going to change the way people feel about an asset or a whole market in an immediate way.
So this is a process which takes time and you will need to wait for the positive news of the ethereum network to be reflected in its price, how long should you wait? At least a few years if you ask me, as there are many indicators which point out to the markets being in a bad shape and we do not know when things will improve.
