[S201]

Lion Air 610 crashed October 29, 2018. BA closed at $357 that day. It continued to go down to $304 on December 17th 2018. By February 25 2019 it hit a high of $440. A month later Ethiopian Airlines 302 crashed sending BA down again. The larger issue beyond this was covid sending the stock plummeting so it didn't really have a chance to rebound after the affected 737 models were recertified and not grounded anymore.

But you're coming at this from a long term investing point of view. If you're day trading or swing trading (which is likely given it's an individual stock and buying individual stocks for a long term investment is rarely a good idea) then it presents an opportunity. Of course, nothing is a sure bet in the market but seeing something like Boeing down 18% can present a short term opportunity for speculators. Would I put BA in my retirement funds? Absolutely not. Would I try to swing trade BA in a case like this? There's a good chance.
