I've written before about how to make millions from thousands, but I think it's also valuable to understand how you might do the opposite. Even if you're not yet a millionaire, the wrong moves could still turn your thousands into hundreds.
The CFA Institute, which grants very respected "CFA" designations to financial analysts who pass its series of rigorous tests, recently released a list of 12 common investing mistakes. Here are three errors particularly worth avoiding.
1. If you fail to plan, plan to fail
Many of us have significant portfolios filled with a variety of investments. We buy this stock because it looks good, and that stock because we read about it somewhere, and this one because it sports a hefty dividend, and that one because it's growing quickly. But do we have any overriding strategy? Nope.
When will we sell any of these stocks? We don't know. How long do we aim to hold them? We don't know that, either. How, exactly, do they fit into our Big Plan? Unfortunately, we don't have one.
All the great investors place their money according to some underlying strategy. Many believe in value investing, buying each stock only a certain discount to its fair valuation. Many are long-term investors, aiming to hang on to their stocks for years or decades, as long as those investments remain promising.
These folks know how much risk they can stomach, and they won't exceed that limit. When the market tanks, as it did in 2008, they don't sell in a panic like so many lesser investors. They know their strategies, and they stick with them.
2. Don't place all your eggs in one basket
Do you own shares of Pfizer
You need to spread your assets over a variety of industries -- and, ideally, over a variety of geographical regions and asset types. American stocks have a great track record, in general, but many other economies are growing more rapidly. Even those that aren't may buffer you a bit, should the U.S. economy falter. By investing in several different asset types, you'll also reduce some of your risk, and be able to enjoy a greater variety of benefits from different global markets.
Large, established dividend payers such as AT&T
Smaller companies, such as NVIDIA
3. Buy only at the right price
Even a company that's obviously terrific, healthy, and growing rapidly can be a terrible investment at the wrong valuation. If a company's intrinsic value is around $100 per share, but it's trading for $140, it's more likely to fall in price than continue its ascent.

To avoid overpriced stocks, look at measures such as P/E ratios and price-to-sales ratios at the very least. Compare them with the company's historic averages, with those of its peers, and with the company's revenue growth rate.

Be the best
The smartest and most successful investors keep thinking and learning about investing. They figure out what mistakes they've been making, and avoid repeating them.
