COMMON CENTS PRINCIPLES OF INVESTING
1. Invest within your circle of competence. If I canât understand the business (say, software, which is beyond the limits of my comprehension), I donât bother. I limit myself to the businesses I can understand. Itâs unrealistic to expect yourself to get acquainted with all the industries in the bourse. Relax. You donât have to take action on every quote the market gives you.
2. Decide based on a preponderance of evidence. I like looking at all the sources available to assess a companyâs prospects. That means looking at everything from branding and âshare of mind,â to the kind of people the managers are. I only make a buy decision when enough evidence tells me that the decision would be well-advised.
3. Keep a margin of safety. This is one of the most important principles in investing. A good investment decision considers all scenarios of profit or loss, and is based on the investorâs conclusion that even if some of the worst prospects are considered, the investor ultimately still makes money, and that the potential returns are worth the risks entailed.
4. Look at the obvious maths. Subpar investing has a tendency to be obscured by formulas that make the analyst feel like he or she has somehow done an exhaustive analysis. Most of the time, such formulas include âprojections,â which, upon closer inspection, are judgment calls that could be right or spectacularly wrong. Anyone who follows âanalyst consensus estimatesâ would know that they are just as often right as they are wrong. Go for the obvious quantitative signs, supported by principle #3. Is the company profitable in a promising industry? If thatâs the case and itâs selling for, say, just a fifth of book value, it may be worth looking at
5. Phenomenology â Do the legwork. Itâs hard to get a sense of a companyâs prospects unless you can get a âfeelâ of its business. Do the legwork. Check the business out. Anybody who would have visited one of Mang Inasalâs first outlets in VisMin in the late 2000s would have known that Injap Sia was up to something. Those who would have preferred Zoom over other conferencing applications would have had a clue about its prospects during a global quarantine.
6. Equanimity, or a healthy sense of indifference. The market rises and falls, and one year may see a rise or fall of 50% in stock value. As long as you are confident about your judgment, relax. If a great company you own tumbles in stock price, you could perhaps see if itâs a good time to own more of the stock.
7. Trust your gut. Youâve done principles 1 to 5. The company passes. And yet, something feels off. Maybe itâs that huge loan the company recently took against good advice. Maybe itâs the fact that, despite corporate figures, the owners are notorious in their communities for being up to no good. Whatever it is, if something makes you feel very suspicious, trust your gut. Investigate deeper. In an activity such as investing where losing money has real opportunity costs, it pays to listen to your innate guards against harm.
8. Do not overdiversify. Some hedges against the vicissitudes of time are good. My personal preference is a good share of bonds and a slice or two of scarce commodities. But, honestly, if you are certain that one business will outperform all the others, why would you water down your returns with, say, the 20th best? Diversification is an acceptable strategy if you are uncertain about your handful of stocks. But, heck, if youâre so uncertain and want to diversify, why donât you just buy the index of the 30 best companies?
9. Study history. People never change. The follies of mankind tend to be the same in every generation. Those who learned about the South Sea Bubble or the Tulip Bubble would have seen the signs in the âNifty Fiftyâ and the Dot Com Bubble. Those who saw the follies of the Dot Com Bubble and the disasters of overpricing stocks unbacked by corporate performance would have had a clue about the potential disasters unbacked mortgages would unleash on the economy. Studying what happened in the past given similar circumstances is often as important as knowing the âoutlookâ for an uncertain future. In some cases, it may be more educational to look back than to guess the future.
10. Be generous. The locker room culture in investing, where some people feel the need to be number one and make the biggest trades, is toxic. The best mitigant for that is to temper your worst impulses with generosity. Keep a bit of every unexpected windfall, but share much of it with the less fortunate. I assure you that you will be happier as an investor and as a person when youâre not doing everything for self-gratification or to finance excesses. Hubris is dangerous in investing. Keep it in check with a bit of self-denial.
