I'll bite.
One asset class that I happened to hold some exposure to were unhedged international bonds (ETFs: BWX and IGOV). Both yielded a positive return during the market turmoil.
Having said that, I think it was really hard to benefit from the drop last few days - other than hedging with for example put options as a general portfolio insurance. That would have only worked if you held these options before the event.
When it comes to Watchlists, I think it is an interesting tool to learn what's happening - or what has been happening - in the markets. More specifically, like you mention, it can be interesting to see what assets (and asset classes) have been trending lately, which can be helpful if you want to construct a robust multi asset strategy that incorporates trend and want to come up with ideas.
It can also be interesting to see what factors and sectors/industries are outperforming and compare that to your own systems.
But the real question for me would be: how do we then indeed incorporate any lessons that we take from the watchlists into a strategy? How do we actually systematize this?
We most likely don't want to completely overhaul a strategy based on one event. We also don't want to be manually adjusting factor weights or exposures based on anecdotal evidence, on something we happen to read or see that day.
To incorporate the information we see in real time in the watchlists we have to be able to convert our observations into signals, and to test them. Which is something that can be done in P123. Let me share some ways to do that.
For sector rotations, one way to do it, would be to test sector or industry momentum as a factor. Sector and/or industry sentiment (earnings revisions, short interest) could be interesting too. I have tried both and find them good additions to a ranking system. Companies that are part of trending industries and/or sectors, seem to continue to perform well on average.
When it comes to certain factors outperforming, I've read some people claim success betting on factor pesistence (Looking for Advice on Optimizing Factor-Based Ranking in Portfolio123 - #25 by sthorson), but when I tried myself (I really wish factor momentum would work - help me show that it actually does), results were mixed. I have also not seen anyone share a practical way of testing this (other than my own) that shows positive evidence.
Macro regimes can be tricky, but some interesting work has been done on the high yield spread, which is available in Portfolio123 - and can be tested as a macro factor for stocks as well as an indicator in a multi asset strategy.
For example, when high yield spreads are low and rising - like they are now - typically risk off assets outperform (like utilities that you mentioned, and bonds that I mentioned). Of course, when markets move so fast, it is not easy to capitalize on that information. What is more useful and interesting, is that when high yield spreads are high and dropping (which I expect to happen in the next days or weeks) - pretty much by any measure of 'high' and 'dropping', certain assets (that most benefit from increasing credit flowing into the system) are very likely to outperform: small and microcap stocks, preferably the cheap, illiquid and levered ones, usually Industrials, Cyclicas and Financial companies. In terms of asset classes, hard commodities spike (e.g. ETF: DBC). See for example: Macro Factors
Another indicator - available in P123 - is the US dollar index (ETF: UUP). When the dollar drops relative to other currencies like it did last few days (though it has been volatile), emerging market and European companies that hold dollar denominated debt, all of a sudden have a much easier time to pay off their loans. It is one reason why emerging market stocks have not sold off much more than US stocks - which usually does happen in these crisis situations.
As both of these variables (high yield spreads and the dollar index) are available in P123, we can incorporate that information in our strategies.
If I would have to make a bet right now - and I have tried to incorporate this in my systems - is that when the high yield spread indeed starts to drop of a peak, it would be to go hard into microcap stocks (and out of capital I hold in my multi-asset strategy). The more the dollar keeps dropping in value, the more weight I give to european microcaps and the opposite for US based microcaps.
