Just buy and hold.
No point to sell.
Stay calm.

Just share a history regarding Mr DIY which is quite similar with 99 S M:

Mr DIY:
26-10-20 IPO price RM160
of course it went up & down & finally after 6 months came to
8-4-21 highest closing price RM424 !!!
it fluctuated & after 1 year came to 22-6-22 bonus issued 3:2 !!!
stock split (share price adjusted to RM200 after 3000 shares free 2000 shares , this made IPO price adjusted to RM 1.06)

99 S M:
9-9-2024 IPO price RM165
of course it fluctuates while it needs time to grow & hopefully go to
9-3-2025 forecast closing price > RM424 !!!
& wait for the bonus issued > 3:2 !!!

So it is still a long way to run.
Somemore, it is a good company. Not many company has good cash flows & management.

So don't hurry to sell when see people sell.
Actually, no one can sell if no one keen to buy.
The time you sell other people keep on buying.
Don't worry too much.
Stay calm & think about it.
The darkest hour is just before the dawn.!!!

Just buy or hold
