What’s Behind The 80% Jump In Alcoa Stock?

AA: Alcoa logo

Alcoa stock (NYSE: AA) has seen a large rise of 80% in the last six months and currently trades at $41 per share. The sharp rally was driven by an increase in global aluminum prices. The gradual lifting of lockdowns, widening coverage of vaccines against Covid-19, and stimulus measures have led to optimism in the markets of faster economic recovery. Additionally, the near bipartisan passage of the U.S. infrastructure bill in the Senate has led to expectations of higher demand for steel, aluminum, copper, etc. which has driven the rally in global prices of commodities. Aluminum price per ton has increased almost 20% in the last six months from $2,130 to $2,555, and over the last one year the price of aluminum is up more than 40%. This has also helped Alcoa record its highest profitability since the time the old Alcoa was split up into two entities – Arconic and present-day Alcoa in 2016, with a net income margin of 11% and EPS of $1.63 in Q2 2021. But will Alcoa’s stock continue its upward trajectory over the coming weeks, or is a correction in the stock more likely?

Some Fun Scenarios, FAQs & Making Sense of Alcoa Stock Movements:

Question 1: Is the average return for Alcoa stock higher after a drop?


Consider two situations,

Case 1: Alcoa stock drops by -5% or more in a week

Case 2: Alcoa stock rises by 5% or more in a week

Is the average return for Alcoa stock higher over the subsequent month after Case 1 or Case 2?

AA stock fares better after Case 2, with an average return of 3.1% over the next month (21 trading days) under Case 1 (where the stock has just suffered a 5% loss over the previous week), versus, an average return of 5.7% for Case 2.

In comparison, the S&P 500 has an average return of 3.1% over the next 21 trading days under Case 1, and an average return of just 0.5% for Case 2 as detailed in our dashboard that details the average return for the S&P 500 after a fall or rise.

Question 3: What about the average return after a rise if you wait for a while?


The average return after a rise is understandably lower than after a fall as detailed in the previous question. Interestingly, though, if a stock has gained over the last few days, you would do better to avoid short-term bets for most stocks – although AA stock appears to be an exception to this general observation.
