I think the value of saving is critical to an individual's well being, and for the economy as a whole. A sound economy is built on savings, not spending recklessly. Investing all your money, however, is not the same as saving. So I have a few things to say.
Things to remember:
1) The stock market doesn't always go up. Over the course of decades you can make a positive (nominal, not always real) return, but you clearly shouldn't invest all your money in equities. There are times to sit on the sidelines and wait for the flames to subside. I don't think the next 5 to 10 years are going to be great years for the stock market, and in fact I expect the stock market to begin showing more losses in 2010. It's still overvalued and the economy is way too unsound in my opinion. Some foreign markets may be a better choice, but be careful.
2) Mutual funds are really not worth it, unless you find a really good one. In fact,
Indexes beat most managers, S&P says. If the market turns sour, so will your fund unless you pick a good fund. You also have fees to pay as well. Plenty of people got burned in 08. Plenty. There are a few out there that made some excellent returns during 08 while everyone was highly negative. Sitka Pacific and Merk Mutual Funds are a few that come to mind.
3) You can still profit if you're a good nimble investor, but you're taking a serious risk. Do your homework, read between the lines, and try to get an honest, clear picture of the market. There are some online sites where you can invest with pretend money with the market to test market strategies. If you are serious about it, play with a few stocks and see how it goes. Nothing too serious.
Save of course, but don't feel bad if you're 'missing' out on so-called huge profits. There's no such thing as something for noting, and we all can't expect to put our money in equities and cash in later and not see the market tank. Just doesn't work that way.
I say all this because my dad was all tied up in the stock market. Luckily, I told him to sell everything in Sept of 08. He missed out on some good rallies later on, but that was the worst that could happen. I wasn't tied up thankfully, but it's very unwise to invest all your savings in equities.
Play it safe people. Savings > 'potential uber big profit'. Considering a missed opportunity as a loss can be a dangerous mind set, because one it's not always true and two it can make you a bit reckless. I'm not saying investing is totally bad, but one may want to think about the current situation and the future before investing. I'm not a financial adviser, but use common sense. Don't invest all your savings in equities, even if you know exactly what you're doing.
