Some, like the pair trading models or the classic section don't seek to beat the market, but try to minimized volatility regardless of market or provide an easy "all weather portfolio" one can save their emotions by happily holding regardless of the market direction.
In the future I want to add more that index FAANG companies, that hedge against inflation, that take advantage of binary outcomes or that focus on income instead of appreciation. In short, many of them beat the market and do so with less risk (look at their Sharpe ratio), many don't because they aren't seeking to.
Their goal is to smooth out volatility, at the cost of performance. Instead of "100% VOO", they invest in a more balanced portfolio like 80% stocks/20% bonds. This means at any given point your portfolio will not have big swings in value, in case you need to withdraw money (like to buy a house) at a sub-optimal time.
