First of all, what makes someone "negligible"? Well according to Riku, one being negligible means they won't affect much to the stock price and won't indirectly hurt the investors. In other words, if the loss of that member doesn't attack the stock price that much, then they are negligible

So how can we measure it? Well these graduation/termination announcements all have 1 thing in common: they always post after the market is closed. So we calculate the difference between the closing price of the day when announcement is posted to the closing price of the closest day post-announcement when the traders are able to trade (they can only trade on weekdays and non-holidays). If the difference is less than 100 yen, then they are negligible. If the difference is over 200 yen, then they are not, and if in between, then it's a 50-50

The reason why we chose 1-day difference is because it's the only correct way to judge the immediate reaction towards the losses of talents, and choosing longer ranges of dates will be complicated because the stocks are affected by other factors like the future outlook, financial results and the overall market condition

So with that in mind, if we based on stock data, which Holomem is negligible? Well we gathered data since 2024 and here is what we find:

1 Yozora Mel (-58)
2 A-chan (-43)
3 Hizaki Gamma (-58)
4 Minato Aqua (-62)
5 Amelia Watson (-55)
6 Sakamata Chloe & Ceres Fauna (-353) *
7 Murasaki Shion (-97)
(*)This is special case because Fauna grad announcement was posted on weekends, but since Chloe and Fauna announced roughly a day apart, we will treat them as one

In conclusion, only the Chloe x Fauna combo is not negligible and Shion is currently 2nd least negligible member in Holo
