Curse of the Hummingbird

 

This article arose from a series of discussions in the SGFI telegram group. I thought I'd share some deeper thoughts on it, as it is relevant to self-improvement and investment.

The person who started the conversation spoke about the advantages of being a jackhammer. A jackhammer has a narrow focus on hobbies; all they can do is focus on one thing and happily lead their lives. The opposite of the jackhammer is a hummingbird—something that flits from flower to flower without ever discovering what they are meant to do. The original inventor of the concept believed that the world needed more hummingbirds because hummingbirds can bring a cross-pollination of ideas and create innovative breakthroughs.

You will find many more metaphors in business literature, such as the hedgehog and the fox. 

As far as my own analysis goes, folks with an S in the MBTI, like the dreaded anal ISTJ, are jackhammers and do pretty well in Singapore, especially the government. In contrast, folks with an N tend to be hummingbirds, as they have big ideas and can apply mental models across domains. I tested ESTJ in my teens and ran with it throughout my engineering career. Still, once I started to pick up investing, the S had no choice but to give way to a more N or intuitive approach towards problems as I began to see investing as a form of liberal art where analysis can come from multiple angles. I was influenced by an old book called Latticeworks by Robert Hagstrom in the early 2000s. 

Are there investing styles for jackhammers? Indeed, using broad index ETFs to construct a 60/40 - VT/BNDW portfolio can be very effective because it can compound between 6-8% over multiple decades. Then, it's just researching ways to reduce expenses and finding more ways to optimise your day job to accelerate wealth creation. Picking this up remains the best defence against financial advisors and paying high commissions to get your money to work for you in the markets,

Dividend investing could be slightly more sophisticated, so it can be suitable for jackhammers. Just target sustainable yields between 5-7%, then stubbornly build up a portfolio of local stocks in a CDP account to reap hundreds of paychecks yearly. It's more complex than 60/40, but the folks who do this are so loyal to this approach that influencers still get cheap eyeballs by provoking and disrespecting "dangerous" dividend investors.

The transition from jackhammer to hummingbirds starts when you become dissatisfied with the Sharpe ratios you are getting. This happens when you interrogate your data and find factors that outperform. Factor investing is very rewarding for hummingbirds because when you see a new factor that works, it is interesting to explain why. Like why do low Beta strategies work? Do people take stock bets based on excitement, so boring stocks are cheaper?  

Technical analysis and charts take hummingbirds slightly further. Some folks love reading tea leaves for different patterns to emerge. I enjoy coding to discover trending ETFs and buy them for better results - that's a very technical investing approach. I've finally moved all my Terra coins into ETH, and I'm developing a momentum-driven algorithm to see whether I can juice my cryptocurrency portfolio in Binance.

However, some strategies only appeal to extreme hummingbirds, and I dislike them. I don't like derivatives and zero-sum games, so sacrificing an upside to juice dividends using covered call strategies is just there to make some folks feel really smart. I'm sure they can make money, but I don't have the time for it. 

Maybe the solution is not to be dualistic about the jackhammer-hummingbird divide.

Based on our personal resources, conscientiousness and intelligence, we have a pool of attention to devote to various interests. 

The jackhammer will narrowly allocate his attention and get deep into a few areas.

The hummingbird will speak thinly and have a passing interest in many fields.

However, many approaches need to be broader and more profound. 

• One way to moderately go into two fields and synergistically use them at work. 
• Another is to supplement a broad interest in many things with one narrower focus on one area you are passionate about.

There are several principles to guide us when determining to pick up a new area of interest:

• If you decide to pick something, a hobby or a field like finance, the opportunity cost is not picking something else, like brewing hipster coffee or writing sonnets. 
• If you keep focusing on one thing, the payoff may achieve diminishing returns. If you have a 6-7% dividend portfolio, and some folks are raving about dividend growth as a better approach, they might be correct, but how much better? Dividend yields are more visible, and dividend growth requires projecting into the future.
• Some things have a J-curve. A project may generate negative returns and frustration but pay off later after you allocate more time and effort. A 1-month violin course is a bad idea. 
• The amount of resources a person can allocate is limited by wealth and talent. Life is not fair.

Because SGFI groups have so many INTJs, it's normal to think that it's a curse to be a hummingbird, as INTJ's significant weakness is the inability to stick to a hobby. At the same time, everyone else can settle with something profound that they are passionate about, so many will die and leave a lot of half-pursued interests for their beneficiaries to plough through (how come your recently deceased uncle got a bongo drum next to a Raspberry Pi?). 

Thoughts of shallow engagements and half-complete hobbies might be a sign of high intelligence and giftedness.

Maybe to be blessed, you need to be an imbecile.
