The run-up in Big Tech stocks and all the hype over AI has put a bunch of investors on "bubble watch." One of those is Howard Marks, the co-founder and co-chair of Oaktree Capital Management. Howard is one of the most famous credit investors in the world, but he has experience in stock market bubbles too. Back in early 2000 — right before the Nasdaq peaked — he pointed out the frothiness in equities in a famous note titled "Bubble.com." So how does he actually spot a market bubble? How does a bubble differ from a bull run? And what is he seeing right now? We chat with Howard about all these things, including his experiences both in 2000 and during the 2008 subprime crisis. This transcript has been lightly edited for clarity.
