Why RDDT stock is up today
Reddit Inc A (RDDT) surged 6.08% to $155.34 on Thursday, driven by reports of robust user growth and improved ad trends. Piper Sandler cited an 8% month-over-month increase in user activity, marking the fastest growth rate of the year. The stock's rise comes amid broader market weakness, with the Nasdaq 100 tumbling due to rising oil prices and yields hitting a 19-year high.
What Happened
Reddit's stock climbed following a report from Piper Sandler that highlighted a significant acceleration in user growth during August. The firm noted that Reddit's user base expanded by 8% month-over-month, with international users surging 29%. This growth is attributed in part to changes in Reddit's ads manager model, which are expected to reset the reported audience size by about 20%. The CEO emphasized that growing users and improving new user retention are key priorities for the next 12 to 18 months. The stock's upward movement was also supported by increased call volume and directional bullishness, with unusual options activity showing $1.3 million in call premiums versus $589,000 in put premiums.
What The Data Shows
The stock has moved up 5.1% over the last eight sessions, from $148.20 to $155.81. Reddit's fundamentals show a market cap of $28.7 billion, a P/E ratio of 34.1, and trailing twelve-month revenue growth of 66.6%. The stock's beta of 2.02 indicates higher volatility than the market. Reddit shares are currently trading within their 52-week range of $119.27 to $282.95. The 52-week tape showed 31 fresh 52-week highs and one fresh 52-week low on September 10. In the last 90 days, insiders have sold 11 times, totaling $47.7 million, with no buys recorded.
What To Watch
Reddit's CEO has outlined a focus on user growth and new user retention over the next 12 to 18 months. The stock's recent performance and Piper Sandler's user growth data suggest continued investor interest in the company's ability to expand its user base and monetize it effectively. Retail traders on r/wallstreetbets are discussing whether the stock is undervalued, though no earnings date is provided to monitor for the near term.
