I am astounded by how overconfident people tend to be when it comes to stock markets and investing. A lot of the conversations I have around buying stocks and investing tend to revolve around people believing they can pick the right stocks and make home runs. Which, I don’t believe is true. I share three reasons why:
The famous Fidelity fund manager, Peter Lynch had one of the most successful careers as a stockpicker. As he describes in one of his books, his approach (I believe) is do some research into companies, looking at things like their overall performance and balance sheet. Then, combine that with obvious business trends he sees around. For example, 2020 and 2021 saw a rise in universities using Zoom for online lessons. The business trends help him think intuitively about whether the business would grow or not. He also split businesses into different growth stages so he has a clear understanding of the type of growth to expect from different companies. That is, Coca Cola may not grow much, but it’ll remain profitable and it has a strong global business. On the other hand, oil companies today are struggling and the industry is likely to contract in response to Covid-19 and oversupply issues. For the average investor, this poses some problems. You have to be able to value a company appropriately and understand the business environment of each enterprise you invest in. This is something most people don’t have the time for or interest in.
We also have to understand that stock prices are influenced by two factors: economics and the things people do.
The economic factors would be the underlying things that affect businesses. Think of things like business cycles: sometimes the economy goes through a recession when few people are hired, and people are generally less capable of splurging on luxuries. Then there are upcycles when prices are high, but there’s money flowing almost everywhere in an economy. There are also industry specific factors that may affect one business but not another. Schools are closed and facing reduced enrollment due to Covid-19, but Amazon and other online retailers are seeing surges in their orders. These factors genuinely affect a company’s ability to earn more money in the future and directly impact how companies are valued. That is, the share price. Or better said, the “fair value” of the company.
However, there are human beings and its usually difficult for everyone to agree to the same thing. People and companies using different methods to value businesses and influenced by their emotions may be willing to pay different prices to own a piece of a company. When people are optimistic, they’re typically willing to pay more. When they are pessimistic, they are typically willing to pay less. These feelings may not actually match the economic value of the business. So, sometimes shares are overvalued or undervalued.
Now an individual operating in these markets risks getting shredded. That is buying when people are optimistic and prices are artificially high. Then selling when prices are low. Speculators typically buy shares expecting the price of shares to go higher. But that’s not guaranteed. It may be that they bought an overvalued stock, and people will become unwilling to pay high prices after they discover the business is not as profitable as previously thought. There are many things that can go wrong which put the average person that tries to speculate at enormous risk.
Some individual investors are able to arrive at the right prices for stocks. But then another factor comes into play. Let’s call it portfolio design. Essentially, every financial instrument has a risk-return profile. When you put cash in the bank, there’s an almost 100% chance you will get back the same amount back in two years, if the bank doesn't close shop. But, in two years, the same amount of money may not be able to buy what it can buy today. Yet, you may buy stocks today and lose everything tomorrow. Or better yet, double your money. The rewards are higher than holding cash but the risk is also higher. Even among stocks, each one has a different level of risk with regards to how likely the business would still be operating in the future and whether they would continue earning healthy profits.
Portfolio design should help you balance these risks by sharing your money among all the things you can invest in. Balancing risk and return, depending on your investment goals.
Yet for the average investor without a ton of money. Getting adequate investment spread may not always be possible. For example, you may split all your money across 5 or 6 stocks, in say the airline industry, yet lose most of your money when coronavirus makes it almost impossible for people to travel.
It’s usually better to find a way to spread your risk across as many financial instruments as possible. It protects your hard earned money from your fallibility. Stock pickers, I’m assuming they can select winners every single time, risk failing woefully at this
I tend to have this argument with friends from time to time. Trading on a day to day basis, to me, is a losers game. Big asset managers, hedge funds etc use computers and AI-enabled data systems that move faster than individuals and are able to act on random insights an individual may not have access to. A firm was once able to trade shares in a company Warren Buffett was going to buy because their internet crawling systems picked up a flight from the city where said company is based, to Omaha (where Buffet lives). Can you do that? Do you also have an ultra-fast machine that can trade at the same speed big financial firms do?
I don’t think so. There’s no point taking risks with your money to eat from the crumbs of big firms.
