Foolish take

Sven Wehrwein's sale of 10,000 shares in AtriCure was a substantial percentage of his holdings, although the transaction alone doesn't necessarily signal a red flag for shareholders. He still owned over 34,000 shares after the sale.

AtriCure stock had a bit of a run up in November, and that may have prompted Mr. Wehrwein to take some profit. The company reported solid third quarter results, with sales up 16% year over year to $134.3 million.

However, AtriCure has not been profitable for years. It posted a net loss of $0.3 million in Q3. On the bright side, that's an improvement over the $7.6 million loss in the prior year.

AtriCure also exited Q3 with a healthy balance sheet. Total assets were $635.4 million compared to total liabilities of $158.9 million. This coupled with revenue growth and a reduction in net loss are positive signs.

For shareholders, AtriCure's financials suggest there's no rush to sell the stock at this time. In terms of purchasing shares, the ideal approach is to watch the company's performance over the next couple of quarters before deciding to buy, looking for further reduction in AtriCure's net loss, and continued revenue growth.
