Many people regard Buffett’s investment theories as near-absolute truths. But today, I’m here to dismantle some of them:

1. “Be fearful when others are greedy, and be greedy when others are fearful.”

Everyone has different psychological thresholds for greed and fear. So how exactly do we determine whether the market is currently in a state of fear or greed? If we rely on data, what kind of data can actually define that people are being greedy, and what kind of data defines fear? For example, does a drop of a certain percentage in a short period qualify? Or a loss of a specific monetary amount? How many people would need to feel fear or act on greed for it to be meaningful? And how do we even ensure the authenticity of this data?

2. “If you’re not willing to own a stock for ten years, don’t even think about owning it for ten minutes.”

Let’s be honest — not 100%, but at least 98% of people who invest are profit-driven. If that’s the case, then if someone like me is able to predict the rise or fall of a stock with high probability, or has strong confidence in a stock’s short-term movement, who wouldn’t be willing to hold it for just ten minutes and then exit with a profit?

3. Buffett believes the market often makes mistakes, due to emotion, panic, and bubbles.

Even if emotional decisions, panic, or bubbles exist, that doesn’t prove the market is making a “mistake.” The market is the market — it has no right or wrong. There’s only a difference between personal gain and personal loss. To prove the market is wrong, one must first define what it means for the market to be “right” or “wrong.” So far, I haven’t seen a valid definition of this. If we define “wrong” as the market not aligning with personal expectations or interests, then the market is “wrong” at every moment — because it can never satisfy everyone’s expectations or interests simultaneously. A market that is “wrong” at all times can hardly be said to be making mistakes. It just is.

Of course, I can challenge more than just these three theories. One day, if I feel like continuing to dismantle Buffett’s ideas, I’ll post more. If anyone disagrees with my rebuttals above, feel free to step up and defend Buffett. I’m genuinely looking forward to a brilliant debate of logic. And if anyone manages to dismantle my rebuttals, I will immediately apologize and admit I was wrong.
