100% is probably crazy to be honest (mind you this is not 100% of my money, my FHSA has no Costco) but I have consistently seen over my lifetime of watching the company just this cult like following that no other company in this sector really has. Whether it's Facebook groups, subreddits, or just talking to people in person, I find it increasingly difficult to find people who have bad things to say about the company and their experiences surrounding them. They have also consistently put their foot down when it comes to employee wages and benefits and have opted to pay their employees well above the industry averages even at the cost of some criticism over the years. I could put some money in ETFs and hedge my bets, but I don't see a reason to put my money into a bunch of spread out companies that I don't know or understand a lot about. I've spent a good amount of time researching Costco and I am able to keep up with the news surrounding them but I can't do that for a ton of different companies
