Consider position sizing and stop losses on JPX trades.

Final Thoughts

High-volume pre-market trading pushed 3628.T stock up 20.82% to JPY 563.00 on 04 Mar 2026, driven by a 196000.00 share spike and a relative volume of 4.12. The intraday surge highlights strong liquidity but not improved profitability, since EPS remains -257.93 and PE stays negative at -1.87. Meyka AI’s model projects a yearly target of JPY 608.30, an implied upside of 8.04% from the current price, yet this outlook carries model risk and is not a guarantee. On JPX, short-term traders should focus on execution costs, confirm continued volume, and monitor the upcoming earnings date of 08 May 2026. For longer-term investors, the elevated price-to-book of 20.34 and negative cash flow metrics argue for caution.
