In recent months, Japanโs stock market โ especially its tech and semiconductor sectors โ has ridden a powerful wave driven by global enthusiasm for artificial intelligence (AI). But now, growing doubts are making many question whether this AI-fuelled rally could turn into a bubble. As a trader myself, I think itโs worth paying attention.

โซ๏ธStocks tied to AI surged hard. For example, companies like Fujikura โ historically a fiber/optical-cable business โ have seen share prices jump over 160% this year, much higher than the benchmark index.
โซ๏ธThat rally helped push major Japanese indexes higher, as tech & chip-related names held a big weight. Many investors were riding the momentum hoping for long-term growth tied to AI demand.

โซ๏ธRecently, tech stocks across Asia โ including in Japan โ have sold off sharply, as global risk sentiment cooled and investors started questioning inflated valuations.
โซ๏ธHeavyweights in Japanโs tech sector, such as SoftBank Group and chip-related firms, dropped significantly as the AI euphoria faded and the โeverything rallyโ came under pressure.
โซ๏ธSome analysts warn that the current AI momentum is powered in large part by speculation โ meaning when sentiment shifts, the downside could be steep.

- Volatility increases โ handle with care. When markets swing hard on tech/AI news, correlated assets (stocks, crypto, commodities) may also be affected.
- Diversify. Having all exposure in โhotโ AI-related names is risky. Spreading across different sectors or asset classes can help soften the blow.
- Donโt chase hype โ wait for clarity. Rather than jumping in at peaks, watch for confirmed demand or fundamentals before entering trades.
- Treat this like a lesson in sentiment & risk management. The AI boom shows how powerful market psychology can be โ but also how dangerous over-enthusiasm can become.

Iโm not turning bearish on AI or tech โ but Iโm more cautious now. The rally feels like a reminder that markets donโt always move on fundamentals; sometimes they ride waves of belief. As someone whoโs still learning, Iโd rather trade with balance: keep a portion in promising growth names, but always keep risk and perspective in mind.
If you trade FX, crypto, or commodities โ donโt ignore whatโs happening in equity or tech markets. When big bubbles wobble, they often shake more than just one sector.

Do you believe this is a โreal long-term boomโ for AI in Japan and globally โ or is this a bubble waiting to pop?
