## $RDDT+WL Technical Analysis & Key Risk Watch

Reddit's inclusion in the S&P 500 comes as the company continues to demonstrate strong financial performance. In its most recent reported quarter, revenue grew by 61% year over year to $805 million. Gross margin stood at 90.85%, reflecting a cost-efficient business model. However, a notable portion of its revenue, nearly 95%, stems from advertising, making the company susceptible to fluctuations in the ad market. Reddit is also exploring revenue streams from AI developers by licensing its data. This strategic diversification could mitigate risks associated with a heavy reliance on advertising.
