… but the U.S. in the last half-century has been “lucky” compared to other developed markets and time periods.
Going forward, the expected stock market risk-premium is about 5 percent. With the risk-free rate at about 3 percent, the long-term expected return on stocks is about
8 percent per year
(standard deviation of 20 percent per year)

Stock Strategies: Four Important Lessons
• Lesson 2: Free-ride on the market competition
– Most actively managed funds and brokerage accounts will under-perform index funds over the long-run
– Choose “total market” index funds

Index Funds Have Low Fees
Performance comes and goes, but costs roll on forever.--Jack Bogle
Value of $100,000 investment33% of your retirement to manager
Low Fees or Low Amounts
Vanguard is a pioneer in low cost index funds (passively managed diversified mutual funds with fees oftenbelow 0.2% per year)www.vanguard.com
Homestead Funds is a pioneer in managing smallaccounts (minimum of $200 for IRA and $500 for regular accounts—NO minimum if automatic scheduled investments)homesteadfunds.com
This was a rewarding activity, say forty years ago, when our
textbook “Graham and Dodd”was first published; but thesituation has changed a good deal since then. In light of theenormous amount of research now being carried on, I doubtwhether in most cases such extensive efforts will generatesufficiently superior selections to justify their cost.

Stock Strategies: Four Important Lessons
• Lesson 2: Free-ride on the market competition– Bad reasons to not index
• Passive investing is boring• War stories are fun to share with friends• Doing nothing about your portfolio is unnerving• Promotional material on indexing is lacking• Habit and tradition
– Good reasons not to index• You are stuck in funds that have a high exit cost• Index funds are unavailable in some plans and foreign markets• Legal proprietary information is routinely available to you• In taxable accounts, complex tax/donation strategies are possible
• Lesson 3: Avoid the hidden price tags of trading– Transaction costs
• Brokerage commissions
• Bid-ask spread
– Risk• Indexing is optimal diversification
• Active funds are more volatile than the market as a whole
– Taxes• Income taxes are triggered by buy and sell transactions
– Time and energy• Beating the market requires a lot of both
