Although, Tatasteel does not have much exposure to the US markets in terms of exports. Some of the companies on our Metal Index are Tatasteel, NMDC, Nalco, Coal India, Hindalco, JSW, Jindal steel, Sail, Vedanta and Hindustan zinc. Doesn't appear that any of these companies should be directly impacted by the tariffs but who know what the markets read into this? However, Stocks like Vedanta have been a drag on the Metal index due to Supreme court order on Ban of mining activities etc. Keep on eye on the Metal Index if you trade tata steel.
When Markets fall, they typically do not care about fundamentals, valuations, support and resistances etc etc. They simply fall/rise. Same on the way up. It is just good old greed and fear in play.
PS: For whatever reason, the general complacence that was there in the global markets over the past few years is getting shaken out. Trading with the larger trend in mind always works. Good luck!
