Shiller Price Earnings Ratio

For quick, clean, revealing charts see Shiller PE and similar dimensionless ratios of prices/earnings (e.g., on multpl.com). In brief:

So remember: don't get caught up in fantasies of wealth without work, save money for the future, avoid high sales or management fees, and rebalance annually between "stocks" and "bonds" (or their equivalents — shares in major businesses and fixed income investments). It really is that simple, over a lifetime!

And for some additional good suggestions, from a Wikipedia summary of Andrew Tobias' "The Only Investment Guide You'll Ever Need":

1. No reliable methods exist of speedily accumulating vast riches.
2. One's income should exceed one's expenditures.
3. If one's expenditures exceed one's income, one should determine the nature of the expenditures and whether they can be foregone with equanimity.
4. One should beware of financial advertising. The advertisers and the financial institutions who offer it often have interests that run counter to those of the small investors whom it targets.
5. One should put one's first several thousand dollars into an account which is unlikely to lose its nominal value.
6. One should employ tax-sheltered accounts to invest for one's retirement and for advanced academic education of one's progeny.
7. One should commit a fixed sum to no-load, low-expense stock index mutual funds every month for the remainder of one's term in the labor market. One should not commit less money than usual after a severe or prolonged market decline. Nor should one commit more money than usual after the market has ascended sharply for years.
8. One cannot reliably achieve higher returns from the stock market than the market average, no matter how much time and effort one devotes to the task. And one can achieve nearly the same return as the market average almost without devoting time or effort to the task by periodically committing a fixed sum to index funds. Therefore, one should make the periodic commitment of one's money and return to one's regular routine.
9. One should omit complex, laborious, expensive, unreliable tactics that are alleged by some to enable one to achieve higher returns than the stock market average. One should merely periodically commit a fixed sum to index funds.
10. Investing in commodities, or coins, stamps, automobiles, collectables, autographs, pictures, art or anything like that is not worth the cost for the amateur investor because of two reasons: You are not an expert, so you will probably be buying from an expert. Second, even if you buy at a good price, you will be selling to an expert, and lose money by selling to one.
11. Low Price-Earnings stocks beat the market the majority of the time. If all stocks are high PE stocks, wait six months for the market to crash.
12. Buy stocks that have dividends at least equal to the amount you would find at a bank.
13. Only invest money you do not need for the next five years, and diversify by not buying all stocks at the same time, or with the same company.
