I'm not certain, but if you want to change your life through stocks...

‌There are certain sectors...
If there is a field that only a monopoly or a few companies can operate in,
it might be worth investing boldly.
Even when the stock price is hitting rock bottom and you're being criticized or feeling anxious,
it eventually gets there someday...
Some companies that come to mind:
Doosan Enerbility - Korea's only gas turbine manufacturer
Samsung, Hynix - HBM
Hanmi Semiconductor - HBM equipment
Hanwha Systems - Korea's only AESA radar, etc....
What's good about Samsung Electronics is... they have quite a few of these..
OLED displays, foundry, image sensors, HBM
In my view, Samsung Electronics... the price is rising now due to DRAM and HBM..
But I think there will be another price surge driven by the foundry business, which is currently being criticized. Someday..
Some experts are already pushing the foundry sector...
