Yeah i got you but you know that the steel industry was also was down for 2 years but it's relatively at a good position again. And if we talk about USA Graphite, they are working on it on their own. And more than 90% we are importing from China which is the biggest source of graphite. US is working on to product Graphite in their own country. And also i have read about their product line which is strong. That's why i think it will be a huge company in next max 1 year. so that i want to invest in this sector? should i?
