Most investors underperform the market because the system they invest through is stacked against them.
Let’s break it down.

Particularly in volatile or sideways markets, where most investors struggle, this approach can make a meaningful difference.
Most investors don’t underperform because they’re careless or uninformed.
They underperform because:
Fix the structure, and outcomes improve.
Because investing shouldn’t feel like guesswork.
