Diversification
Not many receipts. Different things that do not all break together.
Why it matters
It is the closest thing markets offer to forgiveness for being wrong.
In plain language
Diversification means owning things that fail for different reasons: when one falls, the others don't automatically follow. Stocks, bonds, gold, real estate, cash — different weather hurts different things.
The counterfeit version is owning many receipts of the same bet: five tech stocks, a tech fund, and a crypto coin all break in the same storm. That's a collection, not protection.
The test isn't how many things you own. It's how many different reasons your portfolio has to fall.
In real life
The salon with three hundred regulars sleeps better than the agency with one whale client. Nobody's single bad mood can end her month.
In the market
LVMH shares plus a luxury-sector fund looks like two positions. In a luxury downturn, it votes as one.
The common mistake
Counting positions instead of counting bets. Twelve receipts, one weather system.
“Diversification is not about how many receipts you have. It is about what moves differently.”
Quick self-check
If one single piece of news could hurt most of your portfolio at once — what is that news?

If you can name it easily ('tech falls', 'luxury slows'), you're concentrated, however many positions you hold. If you genuinely can't, the bag is doing its job.
