Reddit Inc A (RDDT) fell 7.63% to $164.50 in Monday trading, driven by profit-taking after a strong 12.6% gain on Friday. The stock is set to join the S&P 500 before market open on August 18, a move that typically boosts share prices. However, investors appear to be using the elevated price as an opportunity to lock in gains ahead of the index inclusion.
What Happened
The drop follows a recent surge in Reddit's stock, which climbed to a 52-week high of $282.95 in early August. The company has seen strong revenue growth, with year-to-date revenue rising 66.6% and data licensing revenue increasing 24% to $43 million. Despite these fundamentals, the stock has been volatile, with a beta of 2.03 indicating it moves more sharply than the broader market. The CEO and COO sold shares on July 15, and the CEO sold again on August 4, signaling caution from top executives. Meanwhile, Reddit is joining the S&P 500 in an off-cycle index change, a development that could bring new institutional buying pressure in the coming days.
What The Data Shows
The stock has moved up 14.0% over the last eight sessions, from $155.26 to $176.93, but has since pulled back sharply. Options activity shows 12 notable prints in the last 36 hours, with $9.3 million in call premiums and $4.1 million in put premiums. The largest single print was $4.7 million. Insiders have sold 9 times in the last 90 days, totaling $36.9 million. The stock also printed one fresh 52-week high and 47 fresh 52-week lows on August 18.
What To Watch
Reddit will join the S&P 500 on August 18. Investors should monitor how the stock reacts to the inclusion, as well as any unusual options activity or further insider transactions.
