Boeing shares are down $1.85, or 2.6%, as the US economy continues to struggle.
The Boeing stock index fell 2.2% to a record low of 14,832.70 on Friday.
Boeing’s market value has tumbled from $69.75 billion in the third quarter of last year to $51.98 billion in September.
The stock’s decline in the fourth quarter comes as Boeing announced it was cutting the number of flights in the next year from 9,400 to 4,600, a decision that will affect around 7,500 jobs.
The company announced on Thursday that it would cut the number from 9 to 4 to save $2.5 billion a year, and a further 4,200 jobs will be lost by the end of 2019.
BOEING shares were also down by about 1% to $11.25 on Friday, the biggest daily drop in five years.
The stock was trading above the 10-year high of $12.80 set by the previous record close of $11 in April.
BOEing shares fell 4% after falling by 4.3% on Thursday.
The airline is down by almost 50% in the last 12 months as it struggles with falling demand for its 777-300ER jet.
Boeing stock has been on a tear since it announced its $1-billion restructuring plan for the company.
In September, Boeing said it would trim its workforce by more than 4,000 to save about $3 billion in 2019, but it is now down by 4,400 jobs to about 5,000.
Boeiing has been the subject of criticism by investors who see the company’s financials as unsustainable.
The aerospace giant is on track to lose about $1 trillion in 2019.
The US aerospace industry is expected to lose nearly $2 trillion in 2020, according to data from Bloomberg.
Meanwhile, the Dow Jones industrial average lost 2.3%, while the S&P 500 lost 1.4%.
Banks have also been on fire.
JPMorgan Chase & Co has lost $20.6 billion, while Bank of America Corp lost $6.3 billion.
At the end at 12:47am GMT, the Nasdaq composite index dropped 1.5%.
