IMO,the Gov is posturing to get the best deal it can. It'll hurt, but the stock goes higher once a deal is struck. This trade is not without significant risk, and I wouldn't by this with retirement money. They could nationalize, but they would be shooting themselves in the foot. The Gov would do better for themselves trying to posture the way they are doing now and going for the best deal possible.
Regardless, because of the value, I think buyers here will be rewarded.
I am a very recent buyer. YPF's assets are enormous and it would appear that The government is bluffing, since no other oil company would tough any cancelled YPF concessions. I am a lawyer, but do not know what the proposed YPF lawsuit would do, since the government probably controls the court system.
Since any settlement is months in the future I am sorry I entered this equity.
