Other Nikkei stock going ipo on the same day will tank due to people not vested in yard work, especially this time of year, this stock with people sole trading with allocations should purchase and keep, due to the rarity of other stocks going IPO for 2 weeks.
2週間も他のIPO期間が空いてますので3548がせめて短期的に急上昇の見込みは外国トレーダーからも人気度か高い事は否定出来ません。
