Japanese stocks have gone haywire on Thursday afternoon, reversing sharply in the past few minutes after scaling fresh multi-decade highs earlier in the session.

It had been up as much as 1.5% earlier in the session but it’s now down 1% — quite the turnaround.

There is no obvious reason to explain the move, aside from the fact the index has surged by 17% since mid-September.

The Japanese yen strengthened at the same time the index fell, perhaps prompting profit-taking in those companies that had previously benefited from yen weakness.

The sudden reversal in Japanese markets has also led to selling in other indices across the region.
