The claim is that there are no funds that can make a convincing argument that they will beat S&P.
When you say funds did "exactly that", the "exactly that" you're talking about is not the thing OP is asking for.
Taking on 90% of upside and 100% of downside is one way to make a convincing argument, and nobody does it.
Let's make the dice analogy. You can't make a convincing argument that you will roll a 5, even though people roll 5 all the time. Talking about people that rolled 5 in the past is proving entirely the wrong point.
You're giving an example of beating the market in the past, which is not useful. You can do that with blind luck.
