TOKYO, Oct 31 (Reuters) – Japan’s Nikkei share average climbed to an all-time high on Friday, posting its biggest monthly gain in three decades, as tech stocks rallied following strong sales forecasts from AmazonAMZN.O and AppleAAPL.O.

A weaker yen also boosted heavyweight exporters, following its slide to a record low against the euro EURJPY= and the lowest level since February versus the dollar JPY= on Thursday after the Bank of Japan governor kept a cautious tone in holding interest rates steady.

The Nikkei .N225 closed up 2.1% at the session high of 52,411.34, a record peak that took the index’s gains for October to 16.6% – the biggest since January of 1994.

The broader Topix .TOPX rose as much as 1.4% to reach an all-time peak of 3,348.06, before ending the day with a 0.9% gain at a record closing high of 3,331.83.

On Thursday, Amazon reported its cloud revenue rose at the fastest clip in nearly three years, helping the company to forecast quarterly sales above estimates.

Meanwhile, Apple Chief Executive Tim Cook gave forecasts for holiday-quarter iPhone sales and overall revenue that surpassed Wall Street expectations.

Japan’s chip-sector shares were among the biggest gainers. Socionext 6526.T soared nearly 17%, while Advantest climbed 3.9%, making it the Nikkei’s largest gainer in terms of index points due to its heavy weighting.

Artificial intelligence data center-related shares also gained, with Hitachi 6501.T jumping 7.2%.

Tech stocks have been at the center of the Nikkei’s relentless rally in recent months, joining a global equity resurgence fueled by sky-high expectations for AI.

Japan has had the additional tailwind this month from hopes for aggressive fiscal stimulus under new Prime Minister Sanae Takaichi.

One of her focus areas is AI innovation, meaning Japanese tech shares will benefit from both global and domestic momentum, according to MUFG Asset Management.

Topping the 52,000 level for the Nikkei “is just a step on the way higher,” said MUFG Asset Management Chief Market Economist Naoya Oshikubo.

“We have more room, like another 10% rise from here towards April,” he said. “This is not a bubble.”
