General Motors stock (NYSE: GM) has risen by 6% over the last five trading days. In comparison the broader S&P500 rose by 0.6% over the last five trading days. GM’s stock witnessed a rise on Thursday after an announcement that they expect first half profits to be significantly better than the prior guidance, and a rise in shipments of pickup trucks as they continue to prioritize semiconductor usage efficiently. Will the company continue its upward trajectory over the coming weeks, or is a fall in the stock imminent? According to the Trefis Machine Learning Engine, which identifies trends in a company’s stock price using multiple years of historical stock data, returns for GM’s stock average around 1.5% in the next one-month (twenty-one trading days) period after experiencing a 6% rise in a week (five trading days). Further, the stock is likely to underperform S&P500 returns by 0.5% over the next month (twenty-one trading days).

But how would these numbers change if you are interested in holding GM stock for a shorter or a longer time period? You can test the answer and many other combinations on the Trefis Machine Learning Engine to test General Motors stock chances of a rise after a fall. You can test the chance of recovery over different time intervals of a quarter, month, or even just one day!

MACHINE LEARNING ENGINE – try it yourself:

IF GM stock moved by -5% over five trading days, THEN over the next twenty-one trading days, GM stock moves an average of 3.3%, which implies an excess return of 0.7% compared to the S&P500.

More importantly, there is a 59% probability of a positive return over the next twenty-one trading days and a 49% probability of a positive excess return after a -5% change over five trading days.

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


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

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

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

GM stock fares better after Case 1, with an average return of 3.4% 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 1.5% for Case 2.
