This is an excellent summary of his thoughts and I for the most part agree with them. It's well worth a read. I won't paste the whole thing here but this part is pretty blunt and to the point:
"But it is bad news for me because funds like mine are required to demonstrate negative correlation with risk assets (when they go up like this I go down…), avoid large drawdowns and post consistent high risk adjusted returns.
Oh, and I forgot, macro fund clients don’t like us investing in the stock market for the understandable fear that we concentrate their already considerable risk undertaking. That proved to be an almighty puzzle for a fund like mine that has been proclaiming the stock market as a “safe-ish” bet ever since 2013."
It's really tough right now in general for global macro funds. Their demand does not come from people seeking long equity exposure, they can get that easily in a passive index fund. These funds try to look around the world and find trouble, since trouble is usually not correlated with the long and strong equity crowd. But if there is no trouble or dislocations to be found, these funds tend to flounder and generate low to negative returns. Like trend following right now, this is a tough space to be in unless you are just going to index your clients money and tax them on their wealth which is what most charlatans do in this industry. Hey, it makes the wife and kids happy.
