It is permissible to hold gatherings for the purpose of Khatm-ul Quran or the Khatam of a particular Surah such as Surah Yaseen.
However, this permission is subject to the following conditions:
1- People should not regard it as obligatory or compulsory
2- people should not be forced or compelled in anyway to attend the gathering
3- People should not criticize those who did not attend such gathering
4- Those who attend and recite should only recite Quran for the sake of Allah as much as they can
5- The goal should not be to finish the Quran because that may force people to read unwillingly. Instead the goal should be to read as much as people can.
And Allah knows best.
