TOKYO: Japan’s Nikkei share average rallied to a fresh 34-year peak on Monday as the US S&P 500’s record-high close on Friday buoyed investor sentiment, despite continued signs of overheating in the Asian market.
The Nikkei climbed as much as 1.59% to 36,535.36, a level not seen since February 1990, before closing out the morning session up 1.15% at 36,375.56.
The rally was broad, with 185 of the index’s 225 components advancing, versus 39 decliners and one that was flat.
Every sector gained except for energy, which was weighed down by weaker crude oil prices.
Real estate and technology shares were the top performers.
On Friday, the S&P 500 posted its first record-high close in two years, as AI fever drove big gains for chip shares and other heavyweight tech stocks, with server maker Super Micro Computer lifting its profit forecast.
In Japan, AI-focused startup investor SoftBank Group gained 2.54%, while chip-testing equipment maker Advantest, which counts Nvidia among its customers, climbed more than 3%.
The Nikkei’s 8.7% advance so far this year has put it head and shoulders above developed market rivals, many of which are in negative territory.
However, analysts have been warning of a potential pullback as technical indicators suggest the market has overheated.
The relative strength index (RSI), for example, sits at 75.3, well above the 70 level that signals overbought conditions.
Japanese shares have had an additional tailwind this year from receding bets for an imminent end of Bank of Japan stimulus, particularly after the devastating New Year’s Day quake on the country’s west coast.
Japan’s Nikkei rallies on Wall Street gains, softer yen; SoftBank jumps
The central bank announces policy on Tuesday.
The Nikkei generally rallies on a weaker yen, as it makes Japanese exports more competitive and boosts the value of overseas revenue.
However, an ostensibly yen-boosting hawkish BOJ shift won’t necessarily hurt the Nikkei rally, according to OANDA strategist Kelvin Wong.
“The Nikkei 225 is much more following the US stock benchmarks now, rather than the dollar-yen rate,” Wong said.
“Even if the BOJ signals it’s starting to shift away from negative interest policy tomorrow, I think that could be a positive for the Nikkei, because it gives market participants confidence that Japan is not going to slip back into deflation.”
Although the Nikkei looks due for a short-term pullback, the uptrend remains intact, and a test of 37,000 is likely in coming weeks, Wong said.
