Well, here's the first of my monthly updates. It's a doozy! After launching the algorithm in late October, things were pretty great for a while. I almost doubled my equity over the coarse of a few weeks. And then things turned south. Even though stocks did OK, bonds were a huge drag in December. And then stocks had one of the worst months ever. Right now I'm in a 70% drawdown  and 40% below starting equity .  Obviously not a great time, but it's not totally unexpected. January was one of the worst months ever for a stocks/bonds portfolio, so I'm just happy to still be alive! Hopefully things get turned around in time for the next monthly update!

The turn of the millennium was one of the craziest times in the history of stock markets. Of course, everyone knows about the "dot-com" companies with P/E ratios in the stratosphere. Fewer people understand how the "Y2K bug" forced so much spending on tech that it drove up valuations towards the end of the 90s (and the Fed helped by pumping money). But almost nobody talks about how the market changed . The best example of that change is this chart showing the 1-day autocorrelation of the S&P 500: It's pretty easy to see the regime change there.

I think it probably had something to do with shrinking trading costs, faster transmission of ideas, and increased reliance on automated trading systems. Regardless of why  this change happened, I just want know how it affects trading st...

I was looking at the state of my investments. The chart on my screen looked like this: When the startup I worked for was acquired in 2014 I had received a $200k windfall. Being clueless about investing, I spent an hour investigating options and then chose to put it all into a robo-advisor. Over the next few years I kept adding money as the shares from the acquisition vested. The results weren't bad :  10.6% annual returns . But I had underperformed the market and that didn't sit well with me. I want to get to the next rung on the wealth ladder . The lifestyle I desire requires wealth of around $10M net worth. I want a house on the water in Florida and a boat. Now don't get it twisted: this isn't something I need . It's certainly not going to make me happy . I know...
