Rio Tinto stock (NYSE: RIO) has dropped more than 5% in the last one month and is now trading at little less than $84 per share. The decline was driven by overall weakness in commodity prices during this period. Metals prices had earlier skyrocketed looking at China’s robust recovery post pandemic, and the authorities believe that speculative activities are going on to keep prices elevated. This has led to China announcing that it will crackdown on hoarding and monopolies by focusing on efforts to cool soaring prices of commodities. China’s National Food and Strategic Reserves Administration announced that it will release metal in batches in the near future from its stockpile. Also, U.S. President Joe Biden has proposed to cut back his spending plan from $2.25 trillion to $1.7 trillion amidst opposition from Republicans. This has led to volatility in the global commodity markets leading to value erosion of some of the world’s biggest mining giants like Rio Tinto.

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

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


Consider two situations,

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

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

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

RIO stock fares better after Case 1, with an average return of 2.5% 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 -0.7% for Case 2.
