ATLAS's own quantitative analysis, all in one place.
Plans from €3.99 a month.
ATLAS estimates Companhia Siderúrgica Nacional's fair value at about R$6.01 per share (reasonable range: R$5.40 to R$6.61). At R$6.07, the stock trades within 8% of that figure: close to fair value.
It is calculated with valuation multiples of comparable companies. Confidence in the estimate is low. It is an estimate, not a promise: if the company's results change, so does its fair value.
ATLAS's model gives Companhia Siderúrgica Nacional a 46% chance of finishing higher a month from now (21 trading sessions) than today: close to a coin flip.
In half of the simulated outcomes the price ends between R$5.25 and R$6.78; in 9 out of 10, between R$4.19 and R$8.50. Estimated annual volatility is 80%.
These are two different questions: fair value looks at the business (what it is worth given what it earns) and the odds look at the price over the next month. Companhia Siderúrgica Nacional sits close to fair value and its odds of rising over a month are close to a coin flip. An expensive stock can keep climbing and a cheap one can keep falling, which is why ATLAS shows the two readings separately.
Over the last 52 weeks CSNA3.SA has traded between R$4.19 and R$11.32. Today it is 46.4% below that high and 45% above its low.
Its beta is 1.40: it tends to move more than the market, both up and down.
