PayPal founder Peter Thiel made a big move in Q3: he closed all positions in Nvidia and Tesla, and turned around to buy Apple and Microsoft. At first glance, it seems to be oscillating between the "informed pro" and the "conservative".

Numbers speak: He sold 20,800 shares of Tesla (approximately $72 million) and closed all positions in 538,000 shares of Nvidia (approximately $94 million). But he spent $4.3 billion on buying Apple and Microsoft. In other words, he still has a large amount of cash left unspent, possibly brewing for bigger moves – maybe an AI startup or a quantum computing project.

But there's something "off" here: why sell the growth monster Nvidia to buy Apple, which has a growth rate of less than 10%? From the financial report, Nvidia's revenue growth is explosive, while Apple has entered a slow growth phase. Strangely, the valuations of the two stocks are almost identical.

From a risk perspective, this is clearly about reducing positions — replacing high-growth, high-volatility tech stocks with "safer" blue-chip stocks. But if you ask me whether this trade is smart... well, maybe the pro is playing a deeper game.
