Practical Investment Tips & Pitfalls
- Avoiding Delisting: Exchanges like NASDAQ issue delisting warnings if a stock stays below $1 for 30 consecutive days. Companies use reverse splits to force the price back over $1.
- Negative Market Sentiment: While the total market cap remains unchanged, investors often view reverse splits as a distress signal used by struggling companies to avoid delisting.
