"And yes
@Joe Dupre' no one knows what any stock will do, but by that logic investing in nothing is the "safe" bet. However we have seen banks fail and now Europe is charging depositors to hold money. So traditional savings isn't "safe" and we have seen houses burn down so mattresses aren't either. It's just a matter of what is the "best" place to park your money."
Correct. Investing in nothing is completely safe. BUT, there are investments , such as mutual funds, which have proven track records and are about as safe as reasonably possible. My financial advisor likened them to one large piece of glass compared to a large frame with many small panes of glass. The one large stock "breaks" and you are in trouble. If a few of the small panes break, you are still in pretty good shape. "OOHhhh, what if the stock market crashes and all your investments are lost and the country descends into another depression?!" In that scenario, NO ONE will have money, or a job, or food or much of anything else.
"Buy low and sell high" sounds simple enough, until you actually put your money on the table and try to make that happen. The old adage applies: How to make a small fortune? Start with a large one.
