The same portfolio bug keeps showing up: VOO for large caps, VTI for total market, QQQ for growth. Feels diversified. You own Apple and Microsoft three times and call it a strategy.
- Overlap is shared holdings measured by weight; demand it computed by weight, not by name count - Insist on current holdings, not a stale snapshot, and on whole-portfolio checks, not two-ticker demos - Overlap ignores borders; check international funds against US funds - Free checks that demand your email and end in a newsletter pitch are selling you, not math - Run the check before every buy, not after
Overlap ($4.99 one-time) runs the whole-portfolio check from real holdings data, no email demanded.
