Sina US stocks on the 9th, Boeing CoThe share price fell more than 2% at one point on Wednesday, and several analysts were even more bearish on the stock, citing the plight caused by the grounded 737 Max and the crash of another 737 in Iran.

On January 8, local time, a Boeing 737 with more than 100 people on board crashed in Iran shortly after takeoff, and the plane had planned to fly to Ukraine. The Ukrainian Embassy in Iran said earlier that the crash was caused by engine failure, not a terrorist attack. Later, the Ukrainian Embassy in Iran updated the news, saying that the cause of the accident needs further investigation.

Boeing Co issued the latest response to the crash of Ukrainian Airlines flight PS752, saying, "this is a tragic incident and we express our deep condolences to the crew, passengers and their families." We are contacting airline customers and supporting them in this difficult time. We stand ready to help in any way we need. "

Investment bank Cowen downgraded Boeing Co from outperforming to in line with the market, citing additional costs due to the suspension of 737 Max models and delayed certification.

Analysts such as Cai-Cai von Rumohr of Cowen cut their target price to $371 from $419. He said that while the shutdown reduced the risk of further inventory overstocking, it would also disrupt the supply chain and prolong aircraft manufacturing time, leading to increased spending

Key parameters for the resumption of production of the 737 Max point to widespread results; the timing and financial impact of Boeing Co's recovery from the crisis remain uncertain.

"Boeing 737 Max is likely to make a major correction in the fourth quarter," analysts wrote. "

In addition, UBSAnalyst Myles Walton cut Boeing Co's target price, citing expectations that the 737s would be grounded until mid-March, and that a drop in production would push down recent figures. Cut the target price from $370 to $360, maintaining a neutral rating.

Sheila Kahyaoglu, an analyst at Jefferies, the investment bank, mentioned that Boeing Co had decided to recommend additional simulator training for 737 Max pilots.

With regard to the latest crashes, the analyst said there were very few accidents in the 737 NG, with nine fatal accidents since its inception in 1997.

However, Greg Conrad, an analyst at Jefferies, said his view of Boeing Co had "changed significantly", noting that he had cut his 2019-2022 cumulative free cash flow forecast for the company by $55 per share in the past 12 months. As the battle between the bear market and the bull market continues, analysts believe Boeing Co's free cash flow per share can still exceed $30, but he doesn't expect that to happen until early 2022. Analysts added that Boeing Co had "proper control" of liquidity risk, maintaining a buy rating and a target price of $420.
