Why did the Nikkei 225 today slip?

Reports of a new party formation increased political uncertainty, which tends to reduce risk-taking. That, combined with profit-taking after recent gains, pressured the index. Sector performance was mixed, with chips resilient on external demand and defensives attracting interest as investors sought stability ahead of the Bank of Japan meeting.

How do yen moves affect Japan stocks?

A weaker yen lifts exporters by improving overseas profit translation and pricing flexibility. A stronger yen can weigh on autos, tech hardware, and machinery. Domestic demand and defensives are less sensitive. Traders often adjust hedges and sector weights daily based on USD/JPY moves, especially around policy events and global data releases.

What should investors watch before the Bank of Japan meeting?

Focus on language around inflation, wage momentum, and bond-buying plans. These signals influence yields, the yen, and equity risk appetite. Also track sector rotations, especially in banks, exporters, and defensives. Many investors keep positions lighter into the event to manage volatility and then redeploy once policy clarity improves.

Which sectors look relatively resilient now?

Semiconductors appear firmer on the back of strong AI and advanced-node demand, while defensives like healthcare and staples can cushion swings. Domestic demand names with solid cash flows and dividends also help portfolios. Select financials may benefit from stable yields, but positioning is cautious ahead of the policy decision.
