Just caught something interesting about Japan's market momentum heading into 2026. The rally is honestly pretty striking when you look at the numbers.

So here's what's happening: after the Liberal Democratic Party's election win, Japanese stocks are absolutely crushing it globally. We're talking about the Nikkei climbing over 5% post-election while the S&P 500 is down 1.4% in the same window. That's a pretty wild divergence.

The standouts are wild. Kioxia, the chip manufacturer, has jumped nearly 120% on the year—basically leading the entire MSCI World Index. Defense stocks are having their moment too: Kawasaki Heavy Industries up over 60%, IHI Corp. surging past 50%. Even materials plays like JX Advanced Metals and Sumitomo Metal Mining are seeing 60%+ gains. You can see where the money's flowing—tech, defense, critical resources.

What's driving this? Prime Minister Takaichi's clear policy mandate seems to be the catalyst. Goldman Sachs upgraded Japanese equities to overweight, betting on political stability and fiscal stimulus targeting defense, shipbuilding, energy, and strategic industries. There's real appreciation for the clarity here—investors know what they're getting, and they like it.

Kioxia's story is particularly wild. Up over 1,000% in the past year alone, thanks to relentless AI chip demand. The company beat earnings expectations again last week and popped another 15%. That's the kind of move that catches everyone's attention.

But here's the thing: Russell Shor from Tradu is raising a flag. When this much optimism is already baked into prices, the downside risk starts looking real. He's noting that the Nikkei might be overbought in the short term, and there's not much room left for disappointment. Technical signals are flashing caution.

As of midday Tokyo time, the Nikkei was actually down 0.7%, which might be a reality check after the massive run. Worth watching how this plays out—the setup is compelling, but valuations are getting stretched.
