Being lucky doesn't explain the existence of Renaissance Technologies[1], one of the very first quant fund companies, which has averaged a 71.8% annual return from 1994 through mid-2014. In fact, "the fund’s worst year was a 21 percent gain, after subtracting fees". Of course, it's very much of an outlier — just like Facebook / Google / Uber, if we retrospectively see startup funding and hedge fund investing. [1]: ht…

I'm a big believer in index funds and have been putting my money into them for a long time. But... you have to wonder where this is all ending up as more and more people move to passive index funds. The power of the market is based on millions of individual opinions on the price of a company's stock. On average, over time, these collective opinions will be correct.

I don't think this conversation can really proceed in a sensible manner without the introduction of some numbers. Retail brokers typically charge a commission per trade. If you want to buy many different securities ('cuz diversification), and you don't have a whole lot of money to invest in the first place, you're going to end up paying a large percentage of your initial investment in commission. The exact amount wil…

Just buy them all. Or pick them randomly. Let me remind you that this thread started with an article about the guy who wrote about the blindfolded monkeys.

Your last sentence is correct. See the "Nifty 50" https://en.wikipedia.org/wiki/Nifty_Fifty

"The stocks were often described as "one-decision", as they were viewed as extremely stable, even over long periods of time.

The most common characteristic by the constituents were solid earnings growth for which these stocks were assigned extraordinary high price-earnings ratios. Fifty times earnings was not uncommon."

Agreed, it doesn't explain many other outliers too. A classic exploration of this, and a direct refutation of Malkiel is Buffett's own: https://www8.gsb.columbia.edu/articles/columbia-business/sup...

Brazilian banks have been offering these for decades. It's astonishing that this could be a novelty in the US.

The article mentions the Vanguard 500 Index fund and states that it launched 3 years after 1973. So it's hard to understand what you mean when you call it a novelty in the US. (without being deeply familiar with the history, I think the Vanguard 500 fund must have been one of the earliest index funds anywhere, if not the very first)

It was the first index fund, yep

In any auction, there has to be the first person declaring what the item is worth. If 100% of the investing is passive, there is no first bidder, so how is a stock's value determined? In the current situation, 34% of the money passively follows the active investors. That gives the active investors a 34% amplifier in their action. I'd say the possible bad news is that the larger the passive pool, the less capital it t…

This is exactly how it will balance out. If this passes a threshold such that funds that take advantage of the phenomena will produce a meaningfully higher return than index funds then money will start flowing into such funds balancing out the effect.

Earlier quoted context omitted.

There are companies which will fairly obviously perform well in the future. However, because of active investing, this projected performance gets priced in, so they aren't a bargain. If the whole world except one active investor invested in indexes, then the active investor would have a very easy time, since that projected performance wouldn't be priced in and the stock would be a bargain.

Who would that investor trade with?

I'm not an expert, but index funds still purchase the stocks, so when the active investor bought a stock at an increased price, it would increase the market cap and so the index fund would buy some more of it from them.

It would cost $2500 in fees for me to buy a single share of every stock in the S&P500. Compared with $0 + some negligible MER to buy an ETF with the same money.
