1 "This is a good time to invest in the stock market."
Really? Ask your broker when he warned clients that it was a bad time to invest. October 2007? February 2000? A broken watch tells the right time twice a day, but that's no reason to wear one. Or as someone once said, asking a broker if this is a good time to invest in the stock market is like asking a barber if you need a haircut. "Certainly, sir -- step this way!"
2 "Stocks on average make you about 10% a year."
Stop right there. This is based on some past history -- stretching back to the 1800s -- and it's full of holes.
About three of those percentage points were only from inflation. The other 7% may not be reliable either. The data from the 19th century are suspect; the global picture from the 20th century is complex. Experts suggest 5% may be more typical. And stocks only produce average returns if you buy them at average valuations. If you buy them when they're expensive, you do a lot worse.
3 "Our economists are forecasting..."
Hold it. Ask your broker if the firm's economist predicted the most recent recession -- and if so, when.
