1. You can tell if a Stock is cheap or expensive by the Price to Earnings Ratio.

False: PE ratios are easy to calculate, that is why they are listed in newspapers etc. But you cannot compare PEs on companies from different industries, as the variables those companies and industries have are different. Even comparing within an industry, PEs dont tell you about many financial fundamentals and nothing about a stocks value.

2. To make Money in the Stock Market, you must assume High Risks.

False: Tips to Lower your Risk:
Do not put more than 10% of your money into any one stock
Do not own more than 2-3 stocks in any industry
Buy your stocks over time, not all at once
Buy stocks with consistent and predictable earnings growth
Buy stocks with growth rates greater than the total of inflation and interest rates
Use stop-loss orders to limit your risk

3. Buy Stocks on the Way Down and Sell on the Way Up.

False: People believe that a falling stock is cheap and a rising stock is too expensive. But on the way down, you have no idea how much further it may fall. If a stock is rising, especially if it has broken previous highs, there are no unhappy owners who want to dump it. If the stock is fairly valued, it should continue to rise.

4. You can Hedge Inflation with Stocks.

False: When interest rates rise, people start to pull money out of the market and into bonds, so that pushes prices down. Plus the cost of business goes up, so corporate earnings go down, along with the stock prices.

5. Young People can afford to take High Risk.

False: The only thing true about this is that young people have time on their side if they lose all their money. But young people have little disposable income to risk losing. If they follow the tips above, they can make money over many years. Young people have the time to be patient.
