Leverage Doesn't Add Value
Oaktree Client Letterより：
First, leverage magnifies outcomes but doesn’t add value.
To simplify for my current purpose, risk comes from the combination of what you buy and how you finance it. You can buy very risky assets, but if you don’t lever up to do so, you’ll never lose them to a margin call. Or you can buy fundamentally safe assets, but the combination of enough leverage and a sufficiently hostile environment can cause a meltdown. In other words, investing in “safe” assets isn’t necessarily safe, particularly if you’ve borrowed to buy them.
