Here’s Why Alcoa Stock Saw 10% Drop In A Month

AA: Alcoa logo

Alcoa stock (NYSE: AA) dropped almost 10% in the last one month and currently trades close to $36 per share. The primary reason for this drop has been news from China. With an aim to combat the rising price of finished goods at its factories (and shrinking profit margins for its producers), China’s National Food and Strategic Reserves Administration announced that it will release metal in batches in the near future. Copper and aluminum held in government strategic stockpiles were specifically named as targets of the action. The market expects China to release state reserves of these commodities while also possibly trimming long positions and cracking down on speculative activity. China’s announcement saw volatility in global aluminum prices which led to a drop in Alcoa’s stock price.

But will AA stock continue its downward trajectory over the coming weeks, or is a recovery in the stock more likely? According to the Trefis Machine Learning Engine, which identifies trends in a company’s stock price data for the last ten years, returns for AA stock average close to 3.5% in the next one-month (21 trading days) period after experiencing a 10% decline over the previous one-month (21 trading days) period.

Some Fun Scenarios, FAQs & Making Sense of AA 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 2.3% 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 3.5% 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.
