There are a number of reasons why you should take presentations of outperformance with a grain of salt.

Anybody who has been in the investment advisory business for any length of time knows that clients are gained and clients are lost. Some departing clients might receive something like the following missive from their advisory firms:
Dear Dr. Stanislaus:
I'm distressed to see that your medical practice is leaving us as a client. I well remember years ago when I first met with you and your colleagues at your clinic in Indianapolis.
The reason why you're leaving us is especially concerning to me: Big Bank showed you and your colleagues their portfolios that have earned high returns, and you fell for it. That makes you return-chasers.
No doubt it's easy to succumb to such allures, especially since the 401(k) portfolios our firm has invested and managed for you and your colleagues have experienced a period of relatively low returns over the last few years. You have likely been frustrated with those returns. Still, your returns reflect those of major asset classes the world over in which your low-cost portfolios are broadly and deeply invested. Nonetheless, you turned to other sources that were all too glad to show you those portfolios of theirs that achieved higher returns over the same time period.
One of the certainties of investing is that it will always be possible for you to find portfolios that have done better than your current portfolios. You might read about them in the media or hear about them from cocktail party chatter. Or, in this case, Big Bank showed you selected portfolios of theirs that did better--in the past--than your current portfolios did.
