That begs the wider question: Are investors catching a falling knife or is buying heavily beaten-down crisis stocks a viable strategy?
Take BP – which swiftly became an enfant terrible after the disastrous Gulf of Mexico spill. If you bought BP's stock after disaster and held it until today, you would have lost half of your money. Buying on the dip did not turn out to be a profitable strategy as the losses and legal problems stemming from the environmental disaster rose relentlessly. Other issues like the precipitous drop in the oil price also contributes to BP's stock woes.
Look at Toyota though, which was marred by recalls in 2010, the story looks somewhat different.
Between February 2010, to March 2014, Toyota stock has gained 45 percent. Yes, it too did drop after the recalls. Toyota's stock price had slumped by 20 percent—a $35 billion loss of market value in February of 2010. But the longer term performance shows it has regained speed.
Bottom line – generalizing the investment strategy around three crisis stocks is close to impossible.
But think about this: Apart from the fundamental question of how risk averse you are, the other key issue is also just how long your time horizon for investing is. Buying on the dips may prove a profitable strategy if you're spot-on with timing. However, very few of us are.
In the absence of the light at the end of the tunnel, the more prudent strategy may be to steer clear of crisis stocks. After all, a stock that looks cheap may be a bargain for a reason.
