Hittade en artikel till av Larry Swedroe som jag också gillar där han skriver om de påståenden som ofta görs mot indexfonder:
The author went on to note: “The flow of trillions of dollars into passive funds (along with central bank actions) has pushed financial asset prices through the roof, via massive buying irrespective of price and fundamentals.”
This shows a complete lack of understanding. Passive investors are price takers, not price makers. The actions of active managers drive prices, not those of passive managers. If you want any more proof of that, just look at the huge dispersion of returns we see every year in the stocks in the S&P 500 Index. If passive managers were driving prices, all the stocks would move by the same percentage. The reality is far different.
As one example, in 2017, the best-performing stock in the S&P 500 Index was NRG Energy (NRG), up 132%. The worst-performing stock was Henry Schein (HSIC), down 54%. That’s a gap of 186%! It cannot be explained by anything other than the actions of active managers. I’ll take this opportunity to note that, despite this type of wide dispersion, which is normal, once again, the vast majority of active managers failed to outperform their benchmark indexes.

As further evidence of the absurdity of this claim, just consider the recent sharp drops experienced by Facebook (FB) and Twitter (TWTR).
This past July 25, FB closed at $217.50. After the close, FB reported weaker-than-expected results. The opening price the next day was $174.89 (a drop of about 20%), and it closed at $176.26. Index and other passive funds did virtually no trading on those days (except if a fund had to redeem shares or create new ones, and even then it would trade FB shares in proportion to its total market value in the index, and thus would not have affected FB’s relative price).
The entire change in prices relative to the market was explained by the actions of active managers, both in driving up its relative price before the announcement and in driving it down after the announcement.
för att sedan gå på teknisk knock-out:
Proponents of active management will continue to attack passive investing. In almost every case I’ve come across, these attacks not only are without foundation, they also are absurd and easily exposed as such. But that doesn’t stop them. The reason is simple: Passive investing threatens their livelihood. Thus, their behavior should not come as a surprise.
For those investors seeking above-market returns, the answer is not to engage in active management. While it is possible to win that game, the odds of doing so are so poor that it’s simply not a prudent choice to play.
Instead, the answer is to seek greater exposure to unique, independent factors demonstrating a historical premium that has been persistent across time and economic regimes, pervasive around the globe, robust to various definitions, is implementable (meaning it survives transaction costs), and has intuitive risk- or behavioral-based explanations for why you should expect a premium going forward.
Seek those greater exposures through low-cost, well-diversified, passively managed funds.
