Arguably the hardest step in investing is the first step. Investors who are just starting out face a sometimes bewildering array of choices, a deluge of advice and the dread that if they make a mistake, they will lose everything.
It does not have to be that difficult, though. By following a few general guidelines, investors can make their initial forays into the market. Consider sample, or model, portfolio allocations. These give investors a rough outline of how to apportion their money, however much money they may have.

Large What?Terms like "large cap" and "value" are vague, but they also tend to mean what you think they should mean. Wal-Mart (NYSE:WMT), for instance, is a very large company that has a P/E below the market average and a higher-than-average dividend yield. Not surprisingly, it is considered a large-cap value stock. On the other hand, Apple (Nasdaq:AAPL) is even larger but is growing faster and has richer multiples - making it a large-cap growth stock.
For the sake of simplicity, we are looking only at stocks and bonds here. Other investment categories like hard assets (commodities and precious metals) and real estate certainly have a proper place in personal finance, but those go beyond the scope of this piece.
Model #1 - The Risk-Seeking ApproachA risk-seeking investor is typically one with a long investment horizons (decades) and a willingness to trade volatility and uncertainty for higher overall returns. A risk-seeking approach is going to prioritize growth over value, smaller market capitalization over larger, and will lean more towards international diversification. Fixed income is not likely to be a major part of the portfolio, apart perhaps from international bond and/or lower-rated corporate bonds.

5% - Large-cap value

20% - Large-cap growth

10% - Mid-cap value

25% - Mid-cap growth

15% - Small-cap value

20% - Small-cap growth

5% - Fixed-income

Foreign / domestic - 50% / 50%

This allocation may actually seem too conservative for very aggressive investors, but beginners should probably get a little experience under their belts before really ratcheting up their risk threshold. Why include any value allocation at all for risk-seeking investors? Well, with the exception of the 1990s, value-oriented investment approaches actually out-perform growth-oriented strategies. Still, it is generally true that growth is what fuels returns and this portfolio is designed for those who want growth.
Model #2 - The Risk-Tolerant Approach

10% - Large-cap value

15% - Large-cap growth

15% - Mid-cap value

20% - Mid-cap growth

15% - Small-cap value

15% - Small-cap growth

10% - Fixed income

Foreign / domestic - 35% / 65%

As you can see, this is a much more balanced approach than the first portfolio. This approach surrenders some of the growth opportunities of the more aggressive approach in exchange for a bit more conservatism and predictability.
Model #3 - The Risk-Limiting Approach

25% - Large-cap value

10% - Large-cap growth

20% - Mid-cap value

10% - Mid-cap growth

15% - Small-cap value

5% - Small-cap growth

15% - Fixed income

Foreign / domestic - 25% / 75%

This portfolio is better suited for an investor who believes "slow and steady" wins the race, as well as investors who do not want so much month-to-month or year-to-year volatility in their results. Still, there should be more than enough growth in this sort of allocation to outpace inflation. (For more, check out What is Inflation and How Should it Affect My Investing?)
Security Selection - How Do I Choose?Given this sea of numbers, how should a beginning investor turn those allocation percentages into actual candidates? A lot of that depends upon the time you have to devote to the work and your confidence in your own abilities to pick individual stocks.
Stocks and Mutual Funds
It takes a few hours to properly research a single stock. In that same time, you can thoroughly research a mutual fund, and you can search for them by broad characteristics like "large-cap growth". Moreover, an individual mutual fund is not going to be nearly as volatile or risky as any single one of its holdings. In other words, pick the wrong stock and you could have a 20% loss in one week, but you are unlikely to see such a sharp decline in a fund. Of course, the reverse is true as well - if you can "out-pick" a fund manager, you will outperform.
Exchange Traded Funds
Going a step further, you can find sector-specific ETFs (or mutual funds) that meet those allocation guidelines. For instance, the S&P Biotech SPDR (NYSE:XBI) would certainly fulfill some of the "growth" allocation in a portfolio, while the iShares NYSE 100 Index (NYSE:NY) probably fits the bill for large-cap value seekers. There is more risk here (say, if the entire biotech sector sells off), but more potential for return as well. (To learn more, see How To Use ETFs In Your Portfolio.)
Picking Stocks
Individual stock selection is also always an option. This takes the most time and the most effort, but it allows you to invest in more or less exactly the sorts of companies you want to own. It may take a bit more work here to distinguish growth from value or foreign from domestic - Procter & Gamble (NYSE:PG) gets a lot of its revenue from overseas; it is not a 100% U.S. company even if it is headquartered in Cincinnati - but there is no need for absolute precision here.<br/>Investors do not have to go 100% in any direction. Especially for beginners, it may make more sense to buy one or two individual stocks and then round out the portfolio with ETFs and mutual funds. As you become more comfortable with individual stock analysis and selection, you can gradually replace more and more of the holdings with individual stocks. By the same token, you may find that you are better at selecting managers or ETF concepts than individual companies.
The Bottom Line
In any case, the most important step of all is to begin investing. We have laid out some starting options for you here, but they are just that - options. The right mix of risk and reward or growth and stability is a very personal decision and there is no "right" answer. (For more tips, check out Rebalance Your Portfolio To Stay On Track.)
