“We cannot help thinking, too, that the average individual who opens a brokerage account with the idea of making conservative common-stock investments is likely to find himself beset by untoward influences in the direction of speculation and speculative losses; these temptations should be much less for the mutual-fund buyer.”
Do you see the connection there? Mr. Market shows up not only in the form of the stock market ticker but he’s also the financial industry salesman who is pitching you products. That salesman could be your financial advisor or an advertisement for a triple-leveraged ETF or to make a parlay bet, you get the picture. As Graham warns, “Bright, energetic people - usually quite young - have promised to perform miracles with ‘other people’s money’ since time immemorial.”
The lesson is the same just because Mr. Market shows up doesn’t mean you have to pay attention to him.
Commenting on Commentary on Chapter 9
Zweig starts by offering up the merits of investing in mutual funds, mind you this was just near the advent of ETFs, calling these products “almost perfect”, with a key emphasis on the “almost”. The “almost” is the source of caution for the investor.
The caution is against things like developing a belief that past fund/manager performance should be extrapolated into the future, that the costs the funds charge doesn’t matter, that product design doesn’t matter (for example - do you really know how an inverse ETF works?).
If you’ve followed along through the last 8 chapters it should come as no surprise to find Zweig’s antidote to potentially high cost and poor performing funds to be owing index funds. Writing in 2002, Zweig reminds readers of a fact that still holds true 20+ years later, that very few actively managed funds beat the S&P 500 over a horizon of 10-years or greater. Is it possible to find funds that outperform in the short-run, absolutely, do you think you can consistently find them and then switch to the next out-performing fund at the right time to consistently outperform the market index over time? Probably not.
Once you realize that all of the active trading in the market is actually the market, someone’s wins are another participant's losses. As a collective group active managers cannot outperform, it’s a zero sum game, but a game that has frictional costs paid to intermediaries, which actually makes the game ‘negative sum’. The central idea of index investing was born out of the “Cost Matters Hypothesis”, a central idea that rather than try to beat the market just buy/own everything in the market as cheaply as possible because just as returns compound, costs compound.
I will leave you with this to ponder, why do so many of the world’s best investors consistently state that: “Most people would be better off with an index fund”? And is this advice worth ignoring?
And feel free to add your comments about how passive, index investing destroys market efficiency - that’s always a fun topic.
“The schoolteacher asks Billy Bob: “If you have twelve sheep and one jumps over the fence, how many sheep do you have left? Billy Bob answers, “None.” “Well,” says the teacher, “you sure don’t know your subtraction.” “Maybe not,” Billy Bob replies, “but I darn sure know my sheep.” - an old Texas joke.
