Markets work well.  They are powerful mechanisms for quickly and continuously aggregating the wisdom of crowds.  Markets are highly “efficient,” meaning that the price of a market-based asset (stock, bond, etc.) already reflects all known information about that asset.  In other words, the price of every stock already incorporates everything that is known about the company, and any new information that comes along will quickly and efficiently be priced into the stock.

The implication of market efficiency is that attempts to “beat” the market – whether through stock picking, manager selection, or market timing – are highly unlikely to succeed.  Worse yet, attempts to beat the market are very costly (in terms of both fees and taxes), which nearly guarantees a losing bet for those who attempt it.

While this concept is counter-intuitive – it feels like smart people working hard should be able to beat the market – an overwhelming amount of both academic and real-world evidence has proven otherwise.

Fortunately for investors, long-term market returns are also powerful.  Those willing to accept these returns – rather than try to beat them – will outperform the vast majority of investors attempting to do better and will fully benefit from the market’s robust long-term performance.

By using only the most intelligently-structured and lowest-cost passive/index mutual funds and ETFs in our clients’ portfolios (such as those offered by Dimensional Fund Advisors and Vanguard), we ensure that Geometric clients fully capture these powerful long-term market returns.

This is the “evidence-based” approach to investing.

The single most important decision that an investor makes – the decision that will have the greatest impact on investment results – is the percentage of his or her portfolio to be allocated to “growth” assets versus the percentage allocated to “conservative” assets.

When it comes to investing, risk and return are inextricably linked.  Investments with a greater expected return must come with greater risk, and vice versa.  There is no avoiding this trade-off.

“Growth” assets (equities, REITs, etc.) have higher expected returns than “conservative” assets (government bonds, inflation-protected bonds, etc.), but they come with greater risk and volatility.

Determining the right balance requires a deep understanding of one’s unique goals, risk tolerance, other assets/liabilities, career arc, investment sophistication, demeanor, and other personal factors.  Because these factors are not static, the allocation decision should be regularly revisited to ensure that the portfolio continues to match the investor’s ever-evolving financial situation.

We take great care to ensure that our clients’ asset allocation strategies are continuously aligned with their unique circumstances and goals.

Once the appropriate allocation strategy is in place, investors need a well-defined plan for rebalancing.  When market movement causes an individual asset class to deviate too far from its target within the portfolio – and therefore the overall risk profile of the portfolio to no longer match the investor’s needs – the necessary trades must be placed (remaining cognizant of transaction costs and tax implications) to bring the portfolio back in line.

An investor’s allocation should reflect his or her financial situation, and not his or her prediction about the direction of markets.  While it would be nice to participate in bull markets and to sidestep declines, “market timing” has been repeatedly proven impossible.  Develop a thoughtful plan for asset allocation, and do not allow predictions or emotions to alter that plan

Nobody can reliably predict which individual security, asset class, or geographic region will outperform the others.  For that reason, we diversify.

We diversify across asset classes, meaning that our clients invest in every productive asset class: US Equities, Developed Markets Equities, Emerging Markets Equities, Global Real Estate Investment Trusts (REITs), US Government Bonds, International Government Bonds, Investment-Grade Corporate Bonds, and Treasury Inflation-Protected Securities (TIPS).

We also diversify within asset classes.  For each of the asset classes mentioned above, our clients own hundreds – or often thousands – of individual securities (held via low-cost, passively-managed mutual funds and ETFs).

Combining investments that are not highly correlated (meaning that they do not move in the same direction at all times) results in an overall portfolio with less volatility – and higher risk-adjusted expected returns – than any of the individual assets that comprise it.  This is the power of diversification.

Many investors make big bets – often without realizing it – on a particular company, country, or asset class.  By diversifying properly, we help our clients avoid this critical mistake and the unnecessary risks that come with it.

Small company stocks have been empirically proven to outperform large company stocks, and “value” stocks have been empirically proven to outperform “growth” stocks.

This phenomenon can partially be explained by risk (i.e, small companies are inherently riskier than large companies, so investors demand a premium for owning them).  However, the historical premium is larger than can be explained by risk alone, so including small cap and value stocks in a portfolio improves its risk-adjusted expected returns.

We attempt to efficiently capture these premiums for our clients by investing in mutual funds and ETFs managed by Dimensional Fund Advisors.  Dimensional mutual funds and ETFs are designed to capture the small and value premiums in the most intelligent, cost-effective, and tax-efficient manner available.

Investment costs are the worst enemy of portfolio returns.  Seemingly small fees can have an enormous effect on long-term returns.  Investors must vigilantly protect their portfolios against any unnecessary expenses.

Unfortunately, most investment costs are invisible to the average investor.  The majority of expenses are contained within the investment vehicle (such as mutual funds or ETFs), but because investors never see an itemized list of these fees, they never know how much they are paying or how severely the fees are eating into their returns.  This is a critical error.

The most effective way to minimize investment costs is simple: own low-cost investments.  Passively-managed mutual funds and ETFs typically have dramatically lower costs than their active counterparts.  Geometric prefers mutual funds and ETFs managed by Dimensional Fund Advisors and Vanguard because we believe them to be the lowest-cost options that provide the best value to our clients.

It is also important to minimize the costs associated with buying and selling these investments.  Transactions costs add up, and can result in a meaningful reduction in portfolio return.  At Geometric we perform a systematic cost-benefit analysis on every transaction to determine whether the benefits (rebalancing needs, effective cash utilizations, etc.) exceed the costs (transaction fees and tax implications) for that particular client in that particular situation.

Lastly, it matters where investments are held.  We choose Charles Schwab as our custodian in part because it shares our commitment to low-cost investing, and we work closely with them to negotiate the lowest possible costs for Geometric’s clients.

While returns are nice, after-tax returns are what really matter.  Investors should take advantage of every legal mechanism available to reduce the taxes owed on their investment gains.  Geometric helps our clients minimize their tax burden in several different ways:

First, we ensure that every client take full advantage of any and all tax-advantaged accounts available to them (401(k)s, IRAs, Roth IRAs, 529 College Savings Plans, Health Savings Accounts, etc.).  Maximizing an investor’s usage of tax-advantaged accounts – in which the investments grow tax-free or tax-deferred – can make an enormous difference over time, especially to those in high tax brackets.

Second, we strategically place certain assets in certain account types.  Some asset classes (bonds, REITs, etc.) are tax-inefficient and should be held in tax-advantaged accounts whenever possible, while others (most passively-managed stock mutual funds and ETFs) are tax-efficient and can be owned in any account.  By carefully locating assets in the proper account type, the entire portfolio becomes dramatically more tax-efficient.

Next, we are strategic about when to realize gains within a portfolio.  There are situations when an investor should avoid realizing gains and situations when doing so is desirable.  By understanding each client’s unique circumstances and tax profile we attempt to optimize these decisions.

Lastly, we continuously monitor our clients’ portfolios for tax loss harvesting opportunities.  ‘Harvesting’ a loss (selling a depreciated investment to lock in a loss, waiting the required 31 days, and then buying it back) can be hugely valuable in certain situations, and we work with our clients to identify them.

Every investor should understand what they own, the purpose of each of account, and how it all fits together to form an overarching financial plan.  Unfortunately, there is complexity built into the financial services industry that often prevents this from happening.  We believe that this complexity is confusing, costly, and largely unnecessary.

Most investors have too many accounts.  A brokerage account here, an IRA there, an old 401(k) somewhere they can barely remember; the result is a portfolio that lacks coherence and is difficult to monitor.  We believe that investors should maintain the fewest number of accounts necessary to fully utilize their tax-advantaged options, and no more than that.  Consolidating our clients’ accounts helps to eliminate some unnecessary complexity and redundant costs.

Most investors own too many investments.  The diversification of a portfolio is not determined by the number of mutual funds or ETFs owned, but rather by the underlying investments within those vehicles.  We believe that investors should own the fewest mutual funds or ETFs necessary to be fully diversified, and no more than that.  Not only is this cost-efficient, but it enables the investor to better understand what they own and how it fits into their overall strategy.

We want to make our clients’ lives simpler and for them to feel more in control of their financial situation.  To us, that means a developing customized, understandable investment plans using only those components that are necessary to achieve our clients’ goals.

Investors are continuously bombarded with information that activates two of our most basic human emotions: fear and greed.  The overwhelming majority of this information is “noise,” which has no effect on our long-term financial well-being.  The more completely we tune it out, the better off we will be.

Noise comes in many forms: news headlines that make us feel scared about the market; an “expert” forecast about the short-term prospects for a stock or asset class; our knowledgeable friend convincing us of the merits of a promising start-up or real estate deal.

These all prey on our natural tendencies toward fear and greed, and challenge our commitment to the thoughtfully-developed investment plans we established to meet our specific goals.  Those without plans are even more vulnerable.

Ignoring this noise is simple in theory, but difficult in practice.  Distinguishing between noise and relevant information can be difficult, especially when our pesky emotions get in the way.

The best strategy is to work with an advisor who knows how to spot noise and understands the emotional response that comes with it.  Having a trusted advisor – who understands the plan in place and the reasoning behind it – allows an investor to better filter and react to this constant flow of information.
