It seems you are both arguing separate points and one person isn't aware of that. It's the difference between gambling and investing. When you invest, you own a stock. You don't rent it. You hold it long-term for the tax advantages. The market is repeating a familiar pattern, one that Dean appears to be familiar with.
When I went to work in this industry the Dow Jones Industrial Average was about 832. That's not a typo. Can anyone pick a trend in Dean's chart? Many people can be very happy with their 401(k), thanks to the long-term effect of dollar cost averaging. I'm grateful for every dog-meat sandwich I ever ate, as all of them were buy signals. You can slice and dice the history of the market all you want, (and plenty of people do it for a living), stocks historically outperform any other investment, including real estate, over the long haul. There is nothing new under the sun. So many of these discussions sound like someone just learned that gravity exists, and heat and moisture with yeast will make bread rise. All true, and it's great to see people understand that, but not a new discovery. No one, in the entire history of the stock market, has been able to consistently predict market moves. What would make anyone think that by reading Yahoo!, suddenly they are endowed with a magical gift. The market will make one humble, and the more hubris one has, the more humble one will be made. Wall Street has a long list of forgotten so-called 'gurus'. Anyone can have a lucky call, or even a hot streak, but it never lasts. So far, the calls I've read here have had a similar success rate to flipping a coin. "The market" did this, "the market" did that and I called it. Which market? What did you buy, what did you sell? Do you own the whole market? What was your percentage gain or loss? That's way too vague for calling victory.
This is not an invitation to a debate. The purpose is merely to bring the conversation down to earth. If any of us were that good at calling the market, we sure wouldn't be hanging around here yakking about it.
