However, his basic principles have been extolled upon by several other mainstream finance authors, as well as thousands of other self-proclaimed Bogleheads. If you subscribe to his ideas of low cost index investing, or simply browse their forums, you can probably call yourself a Boglehead too.

While researching my article on The Best Investors of All Time , the term Bogleheads kept coming up when I was researching Jack Bogle. For a quick refresher, Jack Bogle is the founder of Vanguard, and a champion of low-cost simple investing philosophies.

The Bogleheads Investing Forum is one of the most active, and honestly one of the best, resources when it comes to investing Q&A.

If you've searched for anything investing related, chances are you've stumbled across the Bogleheads at some point in time.

What Do Bogleheads Follow?

Bogleheads follow several simple investing philosophies:

1. Live Below Your Means

This is a simple strategy - spend less than you earn. Live below what you need. Save the rest. Frugality is important, but so is earning more.

2. Invest Early And Often

This is one of the main reasons why I started this site. I wanted to encourage young adults and college students to start investing. The earlier you start, the better you'll be financially.

3. Never Take On Too Much Risk, Or Accept Too Little

Investing is a game of risk - but you don't want to go crazy. You can lose money investing. In fact, many people have gone broke investing. But that's rare, and it's near impossible to lose all your money investing if you follow simple advice.

4. Diversify

It's important to never keep all your eggs in one basket. Look at the people who had all their investments with their company stock, and then their company goes bankrupt. Investing in low cost index funds gives you diversity in your portfolio, especially as you mix up stocks, bonds, and other asset classes.

5. Don't Time The Market

Time in the market is better than timing the market. You never will know when the top or bottom is, all you can do is invest for the long term.

6. Use Index Funds

Index funds are fantastic tools to diversify across the stocks. Heck, you can buy the total stock market in one index fund! When it comes to diversification at low cost, there's no better way to do it.

7. Keep Costs Low

Fees are going to be the number one detriment to long term investing success. Keep cost low. Invest in low-cost mutual funds, and be wary of advisor fees. Read this scary story if you dare.

8. Minimize Taxes

Taxes are the enemy - we all hate taxes. Make sure you're taking advantage of tax-deferred investment tools like a 401k or IRA to the max. If you're self employed, you have the solo 401k at your disposal that can really allow you to save.

9. Keep It Simple

Simplicity is important. The more complex you make things, the harder it is to manage. Investing can be simple. Pick a few funds, keep your accounts together, and watch your money grow.

10. Stay The Course

The stock market goes up and down. In fact, as of writing this, it's near all time highs. It might crash. But you need to stay the course and keep investing for the long run. Buy low, sell high - don't fall for the panic and do it backwards.

How to be a Boglehead

Bogleheads invest and keep it simple by buying mutual funds or ETFs that try to mimic the entire market. Or, to build a proper asset allocation for their own individual needs, they may buy a stock mutual fund and bond mutual fund to be diversified in both asset classes. When buying these funds, they pay special attention to fees, and only invest in funds with low fees and expenses.

Taxes are also a huge consideration. To maximize tax efficiency, investment vehicles like 401ks and IRAs are the preferred mediums.

Finally, they stay the course - the stock market goes down, they keep investing. The stock market goes up, they keep investing.
