The decline wiped around $1.8 billion off the stock's market value and put Nissan on track for its biggest single-day drop since falling more than 12% in September 2001.
"Especially given what's happening in China, we have revised our full-year forecast," Nissan Chief Financial Officer Stephen Ma told a press briefing after the release of earnings results.
"This reflects challenges including intensifying competition and logistics issues around our key markets."
The Japanese automaker has responded to a 26% fall in nine-month retail sales volume in China by taking steps to mitigate industry-wide challenges and boost competitiveness in the world's biggest car market, Ma said.
Industry-wide, China vehicle sales rose 12% last year versus the year earlier to 30.1 million vehicles, showed data last month from the China Association of Automobile Manufacturers.
Nissan shifted its China tactics to focus on regaining sales in cities and regions where electrification is happening at a slower pace, Ma told the briefing.
That helped the automaker increase sales by 19% year-on-year to 247,000 vehicles in the final three months of last year, he said.
"We aim to stay in China and we want to be a relevant player and a sizeable player in China," Ma said.
