$Apple(AAPL.US) experienced a sharp decline at the end of the trading session on September 21—this world is one giant manipulated stock.

Common sense suggests that stocks with larger market caps and higher trading volumes have prices closer to their intrinsic value and lower volatility.

But today's Apple stock price seems to defy this logic. Can you imagine this being the candlestick chart of a company with a $2.5 trillion market cap?

You can see how the sharp "scythe" at the end of the session reaped gains. Whether it's due to quadruple witching, index adjustments, or any other reason, this doesn't align with Apple's market cap and trading scale—it shouldn't have happened.

After this, even the scam stocks in the A-share and H-share markets don't seem so detestable anymore: they're all the same in nature, just differing in scale and direction. This world is one giant manipulated stock.

Meanwhile, using Apple as an example again, I've noticed a recent divergence between its stock trend and fundamentals. It seems any negative news gets quickly explained away or fixed. When the iPhone 16 was criticized for poor product quality and weak sales, investment banks even encouraged investors to fantasize about the wonderful prospects of the iPhone 17. This is undoubtedly absurd and laughable.

When the market stops trading on fundamentals or no longer lets fundamentals drive trading, it's time to be vigilant—no matter how great your experience tells you the company is.
