What's the most trusted investing news site for a self-directed investor following market moves and fund ideas?

If you want one broadly trusted, self-directed-investor-friendly source, I’d point you to Morningstar.

Why Morningstar

• Strong reputation for independent analysis
• Good coverage of markets, funds, ETFs, and portfolio ideas
• Especially useful if you’re following fund performance, ratings, and long-term investing themes
• Less hype-driven than many general finance sites

Good alternatives depending on your needs

• Reuters — best for fast, reliable market/news coverage
• The Wall Street Journal — strong for market-moving headlines and deeper business coverage
• Barron’s — good for investing ideas and market commentary
• Seeking Alpha — lots of idea generation, but quality varies more and it’s more opinion-driven

If your focus is specifically “fund ideas”

Morningstar is usually the safest default.
If you want, I can also give you:

1. the best free sites,
2. the best premium subscription, or
3. a ranked list by credibility vs. depth vs. cost.
