Based on the provided story, here is the evaluation:

**Tragedy Degree:**
The story involves Keith's initial economic hardship and the intense pressure Harper faces to ensure a positive outcome for her friend. However, the setbacks are moderate, not deeply tragic, as the story predominantly revolves around overcoming these challenges rather than suffering from them.

**Comedy Degree:**
The story concludes on a high note with Keith's investment more than tripling, leading to an emotionally delightful and satisfying ending. However, the comedic elements are subtle and the story is relatively light-hearted rather than outright humorous or comedic.

Given these considerations, here's the scoring in JSON format:

```json
{
  "TragedyDegree": 4,
  "ComedyDegree": 6
}
