... but the important thing is that when you do find one where you really do know what you are doing, you must buy in quantity.... Charlie and I have made a dozen or so very big decisions relative to net worth, although not as big as they should have been. And in each of those, we've known that we were almost certain to be right going in.
You have to turn over a lot of rocks to find those little anomalies. You have to find the companies that are off the map - way off the map. You may find local companies that have nothing wrong with them at all. A company that I found, Western Insurance Securities, was trading for $3/share when it was earning $20/share!! I tried to buy up as much of it as possible. No one will tell you about these businesses. You have to find them.
There are all kinds of businesses that Charlie and I don't understand, but that doesn't cause us to stay up at night. It just means we go on to the next one, and that's what the individual investor should do.
I do not believe in inheriting your position in society based on which womb you come from... I think a rich person should leave his children enough so they can do anything, but not enough so they can do nothing.
Risk comes from not knowing what you are doing so wide diversification is only required when investors are ignorant. You only have to do a very few things in your life so long as you don't do too many things wrong.
The gross profits in many workouts appear quite small. It's a little like looking for parking meters with some time left on them. However, the predictability coupled with a short holding period produces quite decent average annual rates of return after allowance for the occasional substantial loss.
If you understood a business perfectly and the future of the business, you would need very little in the way of a margin of safety. So, the more vulnerable the business is, assuming you still want to invest in it, the larger margin of safety you'd need. If you're driving a truck across a bridge that says it holds 10,000 pounds and you've got a 9,800 pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay, but if it's over the Grand Canyon, you may feel you want a little larger margin of safety.
Confidence is key. You're not going to put your money - you're not going to leave your money with me unless you're confident I'm going to give it back to you.
