In my experience after the price halves to scare investors (will be a bear trap) then after 2/3 months the market starts going up (halving bull run), which lasts 9 months or 10 months.
Yes you are right that price goes up sometime after halving but we don't know any exact time for how long the bull run will last. But it can be estimated to last 6-7 months. I know of a previous situation that was my first halving into this crypto. I can see a little difference in the halving this time.
