Crushed...

For decades, ExxonMobil was an unstoppable machine. It made gobs of money, spent that cash wisely and rewarded shareholders lavishly. As recently as 2013, Exxon (XOM) was the the most valuable company on the planet. Its market value topped out at $446 billion in mid-2014, the last time crude prices traded above $100 a barrel. But Exxon is now a shell of its former self.

Exxon is now losing money for the first time in decades. Its long track record of raising the dividend is in doubt. Exxon is the poster child for the fossil fuels industry at a time of deep concern about the climate change. And the company's market value has crumbled by a staggering $267 billion from the peak.

Oil companies have been crushed by the crash in prices, which briefly went negative for the first time ever, and collapse in demand.
