classify investments in to different asset types
REITs can be classified as equity, mortgage, or hybrid. A security that sells like a stock on the major exchanges and invests in real estate directly, either through properties or mortgages. Trades like equity but the underlying is a property ot mortgage. So you are investing in real estate but without directly dealing with it. So you wouldn't classify it as real estate. CD looks more like a bond.If you look at the terms and conditions they have many conditions as a bond i.e. callable, that is a very precious option for both the buyer and seller. Self occupied house - Yes an asset because it comes with liabilities. When you need to sell it you have to move out. You have to perform repairs to keep it in good condition. Foreign stock mutual fund - Classify it as Foreign stocks, for your own good. Investments in a foreign country aren't the same as in your own country. The foreign economy can go bust, the company may go bust and you would have limited options of recovering your money sitting at home and so on and so forth. A foreign stock mutual fund definitely belongs in stocks. It's composed of stocks.  Your self occupied house is definitely real estate. You don have to keep in mind,however that selling it would create costs such as rent. I wouldn't leave it out, if doing that would cause you to buy more real estate. This would cause you to be overweighted in the real estate area.  I would tend to think if a CD as cash. While it could be considered a bond, as you said the principal doesn't go down.  The REIT is the toughest one. I would really like to see a graph showing how correlated it is to the real estate market. That would determine where I would put it.
The short answer is that you would want to use the net inflow or net outflow, aka profit or loss.   In my experience, you've got a couple different uses for IRR and that may be driving the confusion.  Pretty much the same formula, but just coming at it from different angles.   Thinking about a stock or mutual fund investment, you could project a scenario with an up-front investment (net outflow) in the first period and then positive returns (dividends, then final sale proceeds, each a net inflow) in subsequent periods.  This is a model that more closely follows some of the logic you laid out. Thinking about a business project or investment, you tend to see more complicated and less smooth cashflows.  For example, you may have a large up-front capital expenditure in the first period, then have net profit (revenue less ongoing maintenance expense), then another large capital outlay, and so on.   In both cases you would want to base your analysis on the net inflow or net outflow in each period.  It just depends on the complexity of the cashflows trend as to whether you see a straightforward example (initial payment, then ongoing net inflows), or a less straightforward example with both inflows and outflows.   One other thing to note - you would only want to include those costs that are applicable to the project.  So you would not want to include the cost of overhead that would exist even if you did not undertake the project. Below is a list of rules that will help you to decide what types of products you should be investing in: I have had similar thoughts regarding alternative diversifiers for the reasons you mention, but for the most part they don't exist.  Gold is often mentioned, but outside of 1972-1974 when the US went off the gold standard, it hasn't been very effective in the diversification role.  Cash can help a little, but it also fails to effectively protect you in a bear market, as measured by portfolio drawdowns as well as std dev, relative to gov't bonds. There are alternative assets, reverse ETFs, etc which can fulfill a specific short term defensive role in your portfolio, but which can be very dangerous and are especially poor as a long term solution; while some people claim to use them for effective results, I haven't seen anything verifiable. I don't recommend them. Gov't bonds really do have a negative correlation to equities during periods in which equities underperform (timing is often slightly delayed), and that makes them more valuable than any other asset class as a diversifier.  If you are concerned about rate increases, avoid LT gov't bond funds.  Intermediate will work, but will take a few hits... short term bonds will be the safest.  Personally I'm in Intermediates (30%), and willing to take the modest hit, in exchange for the overall portfolio protection they provide against an equity downturn.  If the hit concerns you, Tips may provide some long term help, assuming inflation rises along with rates to some degree. I personally think Tips give up too much return when equity performance is strong, but it's a modest concern - Tips may suit you better than any other option.  In general, I'm less concerned with a single asset class than with the long term performance of my total portfolio. For a non-technical investor (meaning someone who doesn't try to do all the various technical analysis things that theoretically point to specific investments or trends), having a diverse portfolio and rebalancing it periodically will typically be the best solution. For example, I might have a long-term-growth portfolio that is 40% broad stock market fund, 40% (large) industry specific market funds, and 20% bond funds.  If the market as a whole tanks, then I might end up in a situation where my funds are invested 30% market 35% industry 35% bonds.  Okay, sell those bonds (which are presumably high) and put that into the market (which is presumably low).  Now back to 40/40/20.   Then when the market goes up we may end up at 50/40/10, say, in which case we sell some of the broad market fund and buy some bond funds, back to 40/40/20.  Ultimately ending up always selling high (whatever is currently overperforming the other two) and buying low (whatever is underperforming).   Having the industry specific fund(s) means I can balance a bit between different sectors - maybe the healthcare industry takes a beating for a while, so that goes low, and I can sell some of my tech industry fund and buy that.   None of this depends on timing anything; you can rebalance maybe twice a year, not worrying about where the market is at that exact time, and definitely not targeting a correction specifically.  You just analyze your situation and adjust to make everything back in line with what you want. This isn't guaranteed to succeed (any more than any other strategy is), of course, and has some risk, particularly if you rebalance in the middle of a major correction (so you end up buying something that goes down more).  But for long-term investments, it should be fairly sound. "Money is a tool. Here is an ""oversimplified"" order of investments:" "There are some index funds out there like this - generally they are called ""equal weight"" funds.  For example, the Rydex S&P Equal-Weight ETF.  Rydex also has several other equal weight sector funds" "Please note that the following Graham Rating below corresponds to five years: Earnings Stability (100% ⇒ 10 Years): 50.00% Benjamin Graham - once known as The Dean of Wall Street - was a scholar and financial analyst who mentored legendary investors such as Warren Buffett, William J. Ruane, Irving Kahn and Walter J. Schloss. Buffett describes Graham's book - The Intelligent Investor - as ""by far the best book about investing ever written"" (in its preface). Graham's first recommended strategy - for casual investors - was to invest in Index stocks.  For more serious investors, Graham recommended three different categories of stocks - Defensive, Enterprising and NCAV - and 17 qualitative and quantitative rules for identifying them.  For advanced investors, Graham described various ""special situations"". The first requires almost no analysis, and is easily accomplished today with a good S&P500 Index fund. The last requires more than the average level of ability and experience. Such stocks are also not amenable to impartial algorithmic analysis, and require a case-specific approach. But Defensive, Enterprising and NCAV stocks can be reliably detected by today's data-mining software, and offer a great avenue for accurate automated analysis and profitable investment. For example, given below are the actual Graham ratings for International Business Machines Corp (IBM), with no adjustments other than those for inflation. Defensive Graham investment requires that all ratings be 100% or more. Enterprising Graham investment requires minimum ratings of - N/A, 75%, 90%, 50%, 5%, N/A and 137%. International Business Machines Corp - Graham Ratings Sales | Size (100% ⇒ $500 Million): 18,558.60% Current Assets ÷ [2 x Current Liabilities]: 62.40% Net Current Assets ÷ Long Term Debt: 28.00% Earnings Stability (100% ⇒ 10 Years): 100.00% Dividend Record (100% ⇒ 20 Years): 100.00% Earnings Growth (100% ⇒ 30% Growth): 172.99% Graham Number ÷ Previous Close: 35.81% Not all stocks failing Graham's rules are necessarily bad investments. They may fall under ""special situations"". Graham's rules are also extremely selective. Graham designed and backtested his framework for over 50 years, to deliver the best possible long-term results. Even when stocks don't clear them, Graham's rules give a clear quantifiable measure of a stock's margin of safety. Thank you." With robo-advisor services, you don't select which funds you buy or sell. All you do is decide on a risk profile, and when you add or remove funds to your account, they decide what to buy or sell based on that profile.  Each service might decide how to do this differently. Looking at Betterment's case, it looks like they try to do rebalancing when you buy. So if you put a deposit in each month, they'll buy the lower priced funds to rebalance your account to the desired ratio. In a taxable account, Betterment likes to optimize your tax liability when you withdraw, so they sell the funds that have lost money before they sell the ones that have gained. You can also use ICS&lt;GO&gt; on Bloomberg and choose the right category (many subcategories, probably you'll start on home builders or something like that). If that doesn't work, press F1 twice and ask it to an analyst. I'm sure they have this info. It's all about risk. These guidelines were all developed based on the risk characteristics of the various asset categories. Bonds are ultra-low-risk, large caps are low-risk (you don't see most big stocks like Coca-Cola going anywhere soon), foreign stocks are medium-risk (subject to additional political risk and currency risk, especially so in developing markets) and small-caps are higher risk (more to gain, but more likely to go out of business).  Moreover, the risks of different asset classes tend to balance each other out some. When stocks fall, bonds typically rise (the recent credit crunch being a notable but temporary exception) as people flock to safety or as the Fed adjusts interest rates. When stocks soar, bonds don't look as attractive, and interest rates may rise (a bummer when you already own the bonds). Is the US economy stumbling with the dollar in the dumps, while the rest of the world passes us by? Your foreign holdings will be worth more in dollar terms. If you'd like to work alternative asset classes (real estate, gold and other commodities, etc) into your mix, consider their risk characteristics, and what will make them go up and down. A good asset allocation should limit the amount of 'down' that can happen all at once; the more conservative the allocation needs to be, the less 'down' is possible (at the expense of the 'up'). .... As for what risks you are willing to take, that will depend on your position in life, and what risks you are presently are exposed to (including: your job, how stable your company is and whether it could fold or do layoffs in a recession like this one, whether you're married, whether you have kids, where you live). For instance, if you're a realtor by trade, you should probably avoid investing too much in real estate or it'll be a double-whammy if the market crashes. A good financial advisor can discuss these matters with you in detail. "Someone (I forget who) did a study on classifying total return by the dividend profiles. In descending order by category, the results were as follows: 1) Growing dividends. These tend to be moderate yielders, say 2%-3% a year in today's markets. Because their dividends are starting from a low level, the growth of dividends is much higher than stocks in the next category. 2) ""Flat"" dividends. These tend to be higher yielders, 5% and up, but growing not at all, like interest on bonds, or very slowly (less than 2%-3% a year). 3) No dividends. A ""neutral"" posture. 4) Dividend cutters. Just ""bad news.""" An accountant should be able to advise on the tax consequences of different classes of investments/assets/debts (e.g. RRSP, TFSA, mortgage). But I would not ask an accountant which specific securities to hold in these vehicles, or what asset allocation (in terms of geography, capitalization, or class (equity vs fixed income vs derivatives vs structured notes etc). An investment advisor would be better suited to matching your investments to your risk tolerance. ACWI refers to a fund that tracks the MSCI All Country World Index, which is  A market capitalization weighted index designed to provide a broad measure of equity-market performance throughout the world. The MSCI ACWI is maintained by Morgan Stanley Capital International, and is comprised of stocks from both developed and emerging markets.  The ex-US in the name implies exactly what it sounds; this fund probably invests in stock markets (or stock market indexes) of the countries in the index, except the US. Brd Mkt refers to a Broad Market index, which, in the US, means that the fund attempts to track the performance of a wide swath of the US stock market (wider than just the S&P 500, for example). The Dow Jones U.S. Total Stock Market Index, the Wilshire 5000 index, the Russell 2000 index, the MSCI US Broad Market Index, and the CRSP US Total Market Index are all examples of such an index. This could also refer to a fund similar to the one above in that it tracks a broad swath of the several stock markets across the world. I spoke with BNY Mellon about the rest, and they told me this: EB - Employee Benefit (a bank collective fund for ERISA qualified assets) DL - Daily Liquid (provides for daily trading of fund shares) SL - Securities Lending (fund engages in the BNY Mellon securities lending program) Non-SL - Non-Securities Lending (fund does not engage in the BNY Mellon securities lending program) I'll add more detail. EB (Employee Benefit) refers to plans that fall under the Employee Retirement Income Security Act, which are a set a laws that govern employee pensions and retirement plans. This is simply BNY Mellon's designation for funds that are offered through 401(k)'s and other retirement vehicles. As I said before, DL refers to Daily Liquidity, which means that you can buy into and sell out of the fund on a daily basis. There may be fees for this in your plan, however. SL (Securities Lending) often refers to institutional funds that loan out their long positions to investment banks or brokers so that the clients of those banks/brokerages can sell the shares short. This SeekingAlpha article has a good explanation of how this procedure works in practice for ETF's, and the procedure is identical for mutual funds: An exchange-traded fund lends out shares of its holdings to another party and charges a rental fee. Running a securities-lending program is another way for an ETF provider to wring more return out of a fund's holdings. Revenue from these programs is used to offset a fund's expenses, which allows the provider to charge a lower expense ratio and/or tighten the performance gap between an ETF and its benchmark. Short term investments, treasuries, current accounts. "When you have multiple assets available and a risk-free asset (cash or borrowing) you will always end up blending them if you have a reasonable objective function.  However, you seem to have constrained yourself to 100% investment.  Combine that with the fact that you are considering only two assets and you can easily have a solution where only one asset is desired in the portfolio.  The fact that you describe the US fund as ""dominating"" the forign fund indicates that this may be the case for you.  Ordinarily diversification benefits the overall portfolio even if one asset ""dominates"" another but it may not in your special case. Notice that these funds are both already highly diversified, so all you are getting is cross-border diversification by getting more than one.  That may be why you are getting the solution you are.  I've seen a lot of suggested allocations that have weights similar to what you are using. Finding an optimal portfolio given a vector of expected returns and a covariance matrix is very easy, with some reliable results.  Fancy models get pretty much the same kinds of answers as simple ones.  However, getting a good covariance matrix is hard and getting a good expected return vector is all but impossible.  Unfortunately portfolio results are very sensitive to these inputs.  For that reason, most of us use portfolio theory to guide our intuition, but seldom do the math for our own portfolio.  In any model you use, your weak link is the expected return and covariance.  More sophisticated models don't usually help produce a more reasonable result. For that reason, your original strategy (80-20) sounds pretty good to me.  Not sure why you are not diversifying outside of equities, but I suppose you have your reasons."
