Isn't it best to just go all-in on Samsung Electronics with whatever cash you have right now?

‌ Earnings are guaranteed and the downside seems to have bottomed out.
My only regret is that I'm stuck in other positions and have no cash left ㅠㅠ
Historically, it feels like the top two semiconductor stocks are at a bargain right now, so why isn't there any new inflow??
If I had even a little bit of cash, I feel like I'd go all-in and buy Samsung Electronics.
There's no such thing as 100% certainty in stocks, but if you look at it long-term, it's bound to trend upward, right?
