Biodesix Inc (BDSX) is not a strong buy at the moment for a beginner investor with a long-term strategy. While there are some positive catalysts such as hedge fund buying and improved revenue growth, the technical indicators, financial performance, and lack of strong trading signals suggest a cautious approach. The stock's recent price trend and insider selling also raise concerns.
