How Many Businesses Do You Have in Your Portfolio?

Some businesses are also more anti fragile than others. Some companies can only do well in good times, so they're kind of harder to have as huge positions. I like to look true diversification. Even though i have like 18 stocks, how many businesses do i have in my portfolio? If i was looking at my portfolio as a conglomerate and i'm the co ihave, i don'tknow, a thousand businesses. How do you think about it?
