Wall Street's Merry Pranks: Things that Matter #4

The revolution in low-cost investing promised liberation from expensive advisors and passive, disciplined wealth-building. Yet for a growing segment of individual investors, access to cheap index funds has become license to trade constantly. The gap between what the narrative promises and what many investors actually do with these tools is widening into something that looks less like empowerment and more like a con.

• The virtue signal is the trap. Investors embrace low-cost index funds as a moral choice, as proof they're doing the smart thing. This perception of doing something right creates permission to do everything else wrong. They trade actively, generate short-term gains, and chase performance between asset classes, all while believing they're being disciplined.
  
• The direct costs are a distraction from the real ones. Everyone counts the basis points saved by ditching advisors. Nobody counts the taxes. Moderate portfolio turnover creates tax impacts equivalent to paying 75 basis points in advisory fees annually. For hyperactive traders using these tools, the hidden costs dwarf the advertised savings.
  
• Random choices matter more than you think. If you selected ten index funds at random from the largest 100 available and weighted them randomly, you'd have a 43% chance of meaningfully different returns than another random selection. The gap between best and worst random portfolios runs 6% annually. Asset allocation choices matter more than fees, taxes, or trading costs combined.
  
• The freedom to choose has become the freedom to fail. Individual investors now manage the exact decisions that require the most expertise. They decide what risks to take and where to take them, with no guardrails, no accountability, and no one to stop them from selling at the bottom or concentrating in the wrong places. The only thing they saved was the advisor who would have said no.
  
• What happens when everyone believes they're doing the right thing while doing the wrong thing? Wall Street gets paid on both ends. The industry profits from low fees on assets that shouldn't have fees, then profits again on the trading volume, the execution slippage, and the behaviors that cheap access enables. The question isn't whether the tools are good. It's whether the people selling them ever intended for most people to use them well.
