Costco vs Walmart? — what our data shows
⚡ TradesZ research ·Updated June 23, 2026 ·~2 min read ·Grounded in SEC data
Costco and Walmart are both giant retail chains where people go to stock up on everyday stuff — and our data has something to say about how seriously big investors are paying attention to each one. The numbers are close, but not identical.
What our data shows
Big professional investment funds have filed paperwork showing they own this stock 19 times — one more than Walmart — and there are zero red flags in our data, which is a good sign.
🐋 13F · 19
Large investment funds have reported owning this stock 18 times with no warning signs at all, meaning it's still very well-followed — just a hair behind Costco in our count.
🐋 13F · 18
The takeaway
⚪Neutral
Both look solid with no warning signs, but Costco has a slight edge in how many times big institutional investors have formally reported owning it — so the choice really comes down to how much weight you put on that extra vote of confidence.
But watch out
Smart-money signals lag the market (13F filings ~45 days) and never guarantee direction — always check the latest price and news yourself.
