Comparison with Current Trade:
- Current trade size: 10,000 shares at $340.66
- The current trade size indicates a significant investment, especially with the share price being higher than previous instances. However, the recent 60-day and 90-day returns are negative (-26.73% and -32.82%, respectively), which deviates from the historical positive trend.

Conclusion:
Hacker Severin's past trades have generally been profitable over longer holding periods, with an average return of 8.0% by the end of the year. The current trade, however, shows significant short-term losses, suggesting a potential deviation in expected profitability. Whether this trade will turn profitable depends on future market conditions.
Based on the provided insider trade details, here is the evaluation:

- Role: Hacker Severin is a Director and Officer, as well as a 10% Owner, which gives some weight to the trade but not as much as a CEO or CFO would.
- Purchase Type: The purchase was likely an open market transaction, which typically indicates confidence since it involves personal financial commitment.
- Size of Purchase: The purchase size of 10,000 shares at $340.66 is substantial, suggesting a strong belief in the company's future prospects.
- Ownership Type: The shares are owned directly, indicating personal commitment and interest in the company.
- Cluster Activity: The information provided does not indicate any cluster buying (multiple insiders buying around the same time).

Considering these factors, the conviction score for this insider trade is Medium. Although the insider is not the CEO or CFO, the large direct purchase and the role as a 10% Owner suggest a reasonable level of confidence in the company's future. However, the negative recent price returns might temper the conviction slightly.
Hacker Severin's recent trade of selling 10,000 shares of DUOL at $340.66 appears to be a bearish signal, particularly in light of the company's recent performance and Severin's past trading behavior. Historically, Severin's trades have been well-timed, often aligning with subsequent moves in the same direction. The size of this sale, while significant, is not an outlier compared to Severin's previous trades, suggesting a consistent approach rather than an anomalous action. The timing of this sale, near the stock's current price of $345.52 amidst a backdrop of poor 60-day and 90-day returns, could indicate a lack of confidence in a near-term rebound and a potential continuation of the downward trend. Given these factors, this insider sale may precede further negative movement for DUOL.
Hacker Severin's purchase of 10,000 shares in DUOL at $340.66, despite recent poor price performance, often precedes potential rebounds, indicating a possible short/mid-term buying opportunity worth monitoring.
