TOKYO, Oct 23 (Reuters) - Japanese stocks fell on Tuesday, with the broad Topix index retreating to a seven-month low as subdued corporate earnings and a pullback in global equities weighed on investor sentiment.
The Nikkei closed 2.67 percent lower at 22,010.78, handing back the previous day’s modest gains, with overnight losses on Wall Street setting the tone early on. The index touched 21,993.07 in intraday trade, its lowest since Aug. 16.
The broader Topix ended the day down 2.63 percent at 1,650.72, its lowest close since March 26, with all 33 of its subindexes in negative territory.
Chinese shares, which had soared the previous session in a boost to the Nikkei, also slipped on Tuesday and pushed down Japanese and other Asian markets.
“Shares are susceptible to falling amid a steady stream of concerning geopolitical headlines. The start to the domestic earnings season has also been marked by several notable downward revisions and this is also weighing on sentiment,” said Takashi Hiroki, chief strategist at Monex Securities.
Concerns over Italy’s budget plan and Brexit negotiations added to the general atmosphere of caution.
