Ααααακριβώς... Και για να μιλάμε με δεδομένα:
More evidence that it’s very hard to ‘beat the market’ over time, 95% of finance professionals can’t do it ή επίσης: Even the Experts Can’t Beat the Market. Why Would You?, απ' όπου θα quotάρω:
There’s a lot of information in this scorecard, but here’s the main headline: Whether you look at the past 3, 5, 10, or 15 years, only about 15% of all professional mutual fund managers were able beat the market.
That’s less than 1 in 6 professional investors. These are people who are trained, paid, and spend their careers looking for best investment opportunities.
And given that index investing allows people to invest directly in those benchmarks they’re being compared to, the only way they can justify their jobs (and the fees they’re charging) is to outperform.
And fewer than 1 in 6 can do it.
On top of that, their average underperformance over the past 15 years was 1.1%. That is, they lost to the market by 1.1% per year for 15 years.

S&P Dow Jones Indices also produces The Persistence Scorecard, which tracks whether the mutual funds that beat the market over one time period continue to beat the market over subsequent time periods.
After all, if there’s genuine skill involved then we should see the same professionals and the same mutual funds outperform time and time again.
The truth is that we see pretty much the exact opposite.
This most recent report looked at all the mutual funds that finished in the top quartile (top 25%) for returns in one year and tracked how they performed over subsequent years. It found that just 1.94% of those funds were able to maintain that top-quartile performance over three years, and a measly 0.34% we able to keep it up over five years.
Το μόνο που αξίζει για τον μέσο επενδυτή (και όχι τζογαδόρο) είναι το συμπέρασμα:
In other words, stop trying to beat the market!!! It’s basically an impossible goal, and it’s especially unnecessary when index investing exists as an easy and readily available alternative that research has shown time and time again to produce better results.
The experts can’t beat the market and you don’t need to try. Your future self will thank you if you don’t.
