So we’ve identified the two basic ways you can invest. That’s great, but how do you know which one to choose? Let’s talk about the active option.
Active investing feels right. We’re active people after all. We shop around for deals, we love sales and Facebook Marketplace. We check weather forecasts on the regular, we set future plans on our calendars. We do research before we buy things (some of us perhaps to a fault), we read reviews, we ask our friends. All of these things are active. So then active investing just seems like the normal way to do things, look for underpriced companies, do some stock research, make a prediction about the future, nothing too out of the ordinary, right?
There’s just one small problem, investing isn’t like normal life. We’ve got really smart people positing that the stock market is efficient, which means there aren’t actually and sales or deals on underpriced companies. Sure, stock prices will generally move upwards, but not because a company is underpriced. New news and information comes into the market and affects stock prices, new things happen that we can’t know for sure beforehand are going to happen. Research into specific stocks is great, professionals are doing it all of the time, but no one person can possibly have a complete understanding of a company, let alone how unknown events in the future will affect the company. There’s just too much data to make picking stocks a long-term viable strategy. Predictions in the stock market are not like weather predictions, we don’t have a radar watching a storm-front move in. And if people believe there is a storm front coming, it’s already priced into the stock prices because again, the market is efficient.
It’s really tough to be a good active investor. Even professionals fail to outperform the market at an extraordinary rate (over the last 15 years, 92% of active funds trading in the S&P 500 have underperformed the S&P 500), and even those who seem to be good at it tend not to repeat their performance. So maybe you’ve guessed by now, I don’t advocate active investing. If you really believe that the market is not efficient and that you or someone you know has a special ability to buy and sell the right stocks at the right time then active investing is the way to test your belief. Unfortunately, the odds are not in your favor.
In part 3, we’ll talk about the alternative option.
Investing is hard. If you’ve visited this blog in the past you’ve probably noticed a lean against active types of investing (buying and selling stocks all the time). Trying to predict the market, pick winning and losing stocks, find the best times to be in or out of different market sectors is really hard. Actually, the data suggests that it’s impossible, or at least no one has ever consistently been able to do it (Efficient Market Hypothesis). So prudent investing doesn’t leave space for active investing, the two don’t mesh. For many people, that’s not a satisfactory conclusion. We like to think we actually can pick winners, maybe not every time, but at least most of the times. We like to think we actually can see trends and understand market movements. We like to think we can make predictions. Well, call me a downer, but those instincts aren’t very helpful.
I’ve been reading through Factfulness: Ten Reasons We’re Wrong About the World – and Why Things Are Better Than You Think by Hans Rosling, a scintillating read. Rosling makes the helpful point that predictions about anything are never certain (he even specifically references the market), and advises readers to be especially wary of future predictions that don’t acknowledge that fact. So here’s my question: why is the future so tough to predict? Here’s my stab at it, with some helpful input from Rosling: the future tough to predict is because the world is far more complicated than we like to think. Rosling notes that the complexity of the systems involved make accurate future predictions essentially impossible. It’s impossible to predict the market because there are billions of factors to consider, all moving and changing every second. Even if we were able to consider each of the billions of factors, we would still have trouble guessing which direction they’ll each move because none of us knows the future. It just doesn’t make a ton of sense to actively trade stocks based on our limited understanding of market factors, not even for professionals. But there’s still happy news here. Even though we don’t know how the market will move today or next year, we do know that the long term general stint of the market is up. So we can actually stop worrying about predictions and news and market trends, those things ought to be the least of our concern, all we have to do is own the whole market as efficiently as we can and stay on for the ride. Owning the market efficiently is a separate discussion, that’s something professionals can actually help with, but the first step is to admit the prediction problem.
