The whole point of index funds is that individual decisions - no matter how well reasoned they appear - don't seem to work out long term. The decision protocol that looks good today and may have worked once, twice of five times in the past will eventually lead to a ruinous decision later on that wipes out all the prior gains.
If the logic you describe works for one company why wouldn't it work for two, or five or ten out of SP500?
Heck if you can indeed pick any winner even by just a 2-3% gain than the passive index, why wouldn't you better off by building a fully custom curated SP500 that contains companies that are more likely to succeed? That 3% adds up to massively more money long term.
The whole point of active trading is exactly that, a thinking logical human being, adding all their intellect ought to be more successful than passively doing nothing.
Yet history says otherwise. Even when faced with decades long evidences active traders still believe they can do better than passives.
- cj 4y agoPast results are not an indicator of future performance. I think the same trope applies to the classic thinking of “passive investing is always better than active investing” Historically, yes. But in the future? Who knows! (This is also exactly what the article we’re commenting on is speculating, that the characteristics of ETFs in the market has changed substantially over the past 10-20 years, which is indeed an argument that past performance isn’t proof of future performance.
- glofish 4y agoThat is a valid point - no one knows what the future holds But we have to take into account that the active traders have been repeatedly making the same claim. How many times is one allowed to make the a similar claim before losing credibility... Recall Warren Buffett' bet vs Hedge Funds https://www.investopedia.com/articles/investing/030916/buffetts-bet-hedge-funds-year-eight-brka-brkb.asp https://www.investopedia.com/articles/investing/030916/buffe... Notably the period included an interval of a stock-market collapse and massive volatility - where smart decisions ought to have mattered more. So the credibility of the above statement that this time will might be different feels severely weakened.
