re: Good ETF or Vanguard fund suggestion...

I use Vanguard exclusively....I like their approach in general. So I don't know what this Bogle is.

But the difference between sector stock and stock picking is how you apply it.

Most stock picking is looking to sell for a profit in the next 3 years or less, sector is more long view, and gives you diversification past a single company.

I only really use Energy (because I really done see oil exploration stopping being lucrative in the next 20 years), consumer staples (solely as a bear market/stagnant hedge), and I'm debating to get in mining/previous metals.

Also, I use sector to also mean classifications of stock, such as mid cap growth or dividend appreciation stock.
