There are countless books, magazines, newsletters, podcasts, blogs, television programs, and more dedicated to helping investors make the best possible decisions when it comes to selecting and managing investments. Far less energy and commentary is committed to the topic of how not to make the wrong moves. The potential consequences of these behavioural blunders and how you might be able to avoid them.
#1: Trying to control things you can’t
Countless factors drive global markets. Randomness rules, so predicting how these myriad variables will influence securities’ prices is impossible. Thinking otherwise is foolish. Deep down, we all know this, but we prognosticate nonetheless. What’s more, we have a tendency to think that we not only know how the future will take shape, but that we have some part in shaping it. Investors cannot control the path of interest rates, increases in productivity, the level of a company’s stock price, and so on, but we often act as though we can. The illusion of control is pervasive. It is in some ways a form of self-preservation, and it’s been linked to positive mental health. But as investors, it can be hazardous to our wealth. The illusion of control can lead to overconfidence. Overconfidence can lead to overtrading. Overtrading will almost inevitably leave you short of meeting your goals. While I could go on forever enumerating the things that we cannot influence, the list of those things we can control as investors is much shorter. The most meaningful levers we can pull to affect our investment outcomes are as follows:
- Save. Sock away as much as you can. This is the investor’s equivalent of advising you to eat dark green leafy vegetables. We know it’s good for us, but we’d like it better on a Junk-foods. The earlier we begin saving, the better, as it buys us more time for the magic of compounding to work in our favour.
- Invest: This may seem obvious, but the biggest determinant of your investment success isn’t which stocks or funds you pick, or how you allocate your assets, but simply whether you’re in the market at all.
- Allocate your assets appropriately: Asset-allocation matters, though it’s a distant second to simply being invested in the market. How you allocate your assets depends on your goals, your time horizon, and your willingness and ability to assume risk, among other things. Having an appropriate mix of stocks, bonds, and cash will do more to move the needle than trying to pick the best securities or managers you can find.
- Minimize costs: Fees, commissions, taxes—every penny spent covering these costs is a penny that will not compound over time to be savored down the road. So spend every penny wisely.
- Avoid taxes: its not “evade taxes.” While we can’t control tax policy, we can respond to it. Locating less tax-efficient assets (closed-end funds, for example) in tax-deferred accounts and investing in relatively tax-efficient vehicles (such as equity ETFs) in taxable accounts can help you avoid putting any more pennies into tax pocket than you have to. There are countless things investors cannot control, but we often kid ourselves into thinking we can. Avoid overconfidence by keeping this short list nearby.
#2: Recency Bias:
Recency bias describes our tendency to extrapolate our recent experience into the future. Stocks have been marching higher for the better part of a decade, so surely they’ll only continue to climb.. Recency bias can become particularly dangerous in bear markets. Falling stock prices can lead to panic selling, and shellshocked investors can be slow to get back in once markets rebound. There’s plenty of evidence that the psychological effects of the global financial crisis linger with investors to this day, as many of them have remained on the sidelines for much of the ensuing recovery. Remember, whether or not you are invested is the most painfully obvious determinant of your outcomes. Sitting out on a nearly decade-long rally has been a serious setback for many. Inevitably, we will be lured by the siren song of “This time is different.” It’s true that every zig and zag in the market is driven by distinct factors from the zigs and zags that preceded it. So, yes, technically speaking, every time is different. But what’s also true is that the long-term trend in markets has been positive for more than a century. Markets grow as economies grow as corporate earnings grow. This trend has persisted through countless crises. So if there’s any good way to avoid recency bias, I’d suggest that it would be to periodically look at the arc of the markets during the past 100-plus years as a reminder that every time is different, but the markets are still driven by the same fundamentals.
#3: Paying too much attention
Our most meaningful investment milestones are decades away, but our attention is monopolized by the moment. Paying too much attention to our investments today can put us at risk of missing goals that are years away. One of the chief side effects of monitoring our investments too closely is that it fuels our aversion to loss. Loss-aversion is but one suitcase among our abundant evolutionary baggage. The theory is that we feel far greater pain from losses than we experience pleasure from gains of equal magnitude. The likelihood of losses in any given one-year period is far greater than the probability of losing money over a longer horizon. But the authors found that annual reviews led investors to behave as if their investment horizon was a year out and not 10 or 20 or 30. This leads many to take less risk (by allocating less to stocks, for example) than is necessary to meet their longer-dated goals. The best way to shake this behaviour is to simply stop paying so much attention to the markets and our portfolios. I am a firm believer in an approach to portfolio monitoring and maintenance that borders on benign neglect. There is so much noise in the markets that the signal typically fades into the background. Tuning out the noise will also help to diminish the illusion of control and recency bias. In recent years, I personally have made a habit of only looking at my own investments once every few months or so. I’ve found that every time I turn up the volume knob on the market’s noise-making apparatus, it’s tempted me to tinker with my portfolio. While it’s tough to put the market on mute, I think we’d all be better served by tuning out a bit more often. Conclusion We spend a huge amount of time trying to make smart decisions with our money. I think its possible that we could add just as much value—if not more—by avoiding dumb ones. The most costly errors we make as investors tend to be mental ones. Being aware of our biases is an important first step in preventing these errors. But awareness alone will not suffice. By focusing on the handful of things that we can control, keeping our eyes trained on our long-term objectives, and tuning out the noise in the market, we can boost our odds of building and sticking to a plan that will help us to meet our goals.
