<p>As someone who has worked in the financial industry for a long time, putting all your money into any one thing is not wise. Professional money managers don’t do that, they hedge money across markets and especially in things like hedge funds, they are trading using sophisticated algorithms across financial markets to achieve their goals. There are all kinds of financial systems out there people promote, the ones saying you can get rich trading commodities, buying gold, etc…and most of them make money selling the systems.</p>
<p>Single unit investing, like real estate, is great if they are booming, but what happens when the bubble bursts? People who put a lot of money into real estate before the crash recently got burned big time, many of them saw their wealth wiped out, collecting rare coins is great, but the problem is collectibles go through waves and then crash, you get the drift. Attaining expertise as one poster said is great, but the problem is even experts lose their shirt in single markets like this, trading firms full of experts go bankrupt and so forth because no market is entirely predictable, whether it is real estate, bonds, stocks, commodities, you name it. </p>
<p>I agree with others, it is great you are thinking of investing and I agree that once you are working, having regular savings is great, and 15% would be a nice number, if achievable, but if not, any number. With savings, try to put some of it into long term investing (401k’s, especially where employers match it, are worth maxing out, since they are before taxes which makes it cheaper versus after tax savings, IRA’s, etc) and some of it into more liquid investments, like money markets, mutual funds and such, so if an emergency happens you have cash to handle it (they usually tell you to try and have 6 months worth of income saved, in case of job loss). </p>
<p>In terms of where to invest it, there is nothing wrong with investing your own money, but quite honestly I think you would do better having some you do yourself, and put the rest into mutual funds and the like. Why? Especially in the equities markets trading as an individual investor is difficult on a large scale, most of the activity in the markets is large scale trading based on sophisticated modelling that can cause a lot of issues for the individual investor, and quite frankly, it is very easy to lose a lot really fast. Funds offer a way to get into whole markets, there are funds that invest in commodities, there are funds that invest internationally, in risky start up companies, in small, medium and large cap investments, bonds, and it would be wise IMO to be diverse with those, too. Some funds make their money by appreciation of share value, others do so by returning dividends (which you can re-invest into more shares). A good strategy is when younger, lead your investments towards more risky but high yield investments (like, for example, a tech fund that invests in small companies) and the rest into more mature, large cap funds (so for example, 70% high yield/high risk, 30% lower yield/less risk). For funds you are keeping for an emergency, might be better to put that into a muni bond fund or money market fund, won’t make a lot of interest, but they are generally liquid (can be cashed in rapidly) and are safe. As you get older, the ratio would change towards more in lower yield/lower risk investments and less in high risk ones. </p>
<p>I agree with others, there are some pretty good books out there on investing, it would be wise to read up and see what they are talking about, but I recommend staying away from the books that promise ‘wealth at 30’, ‘getting rich the ez way’ and so forth, and read books by investing experts like Peter Lynch and so forth. </p>
<p>The key is letting it build up over time so that you aren’t in the position where down the road you have to take risks to try and make up for lost time. The fact that you are thinking about this at 18 is a really good thing, I think learning over the next several years will help you get into it when you are actually working and earning money:)</p>
