Why Did Roku Stock Drop 10% In A Week?

Roku stock (NASDAQ: ROKU) has dropped almost 10% in just the last one week and currently trades at $428 per share. The recent decline was driven after reports surfaced of Cathie Wood, the founder and CEO of ARK Investment Management, selling Roku shares from ARK’s exchange-traded funds. Wood has off loaded half a million shares of Roku since the end of June 2021, with total sales amounting close to $239 million. The news assumed significance as less than a month back Wood had said that investors were making a mistake by selling so-called stay-at-home stocks like Roku. But will Roku’s 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 four years, returns for ROKU stock average over 11% in the next one-month (21 trading days) period after experiencing a 10% fall over the previous one-week (five trading days) period.

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

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

Answer:

Consider two situations,

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

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

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

ROKU stock fares better after Case 1, with an average return of 10.9% 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 8.3% 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?

Answer:

The average return after a rise is understandably lower than after a fall as detailed in the previous question.
