Chicago Quantum Analysis of 1,755 Dividend Paying US Common Stocks (Jan 4, 2021 market close)
Updated Jan 31, 2021 with market results.
On January 4, 2021, after a down day in the US equity markets, I decided to do a ‘big run’ of our quantum algorithm against all US common stocks in four major exchanges. This included 3,569 stocks across NASDAQ (Q&G), NYSE and NYSEAmerican.
I was going to trade on this ‘in-house’ run but in a YouTube AMA this morning I disclosed the picks instead with a commitment to not take a position in any stocks listed for at least 24 hours. The Chicago Quantum Net Score (CQNS), which maximizes expected return (based on the Capital Asset Pricing Model), and minimizes variance during the measurement period. This is a proprietary reformulation of the Sharpe Ratio concept to run on a quantum computer.
So, the CQNS portfolio consists of four, evenly weighted US listed stocks (25% invested in each), $DHI, $KELYB, $SLGN, and $WIT. However, it took us a while to get there, and this article will tell the story. There was at least one surprise (NYSE lists and sells retail bonds…who knew?).
What do I see when I view this chart? I view four stocks that move in different directions on most days, but overall they went up as a team (equally weighted positions to start). In this case, the portfolio was up about 40% last year. We want to find zigs and zags between the stocks and we do.
I left the ‘dividend validation’ selection on. This selection would now only analyze stocks that pass data validation and that paid a dividend during that period. This left us with 1,755 stocks to analyze.
We recognize this has been a very strong US equities market, and our model provided a market return index of 17.26%, and a riskfree rate of return of 1%. All 1,755 stocks together provide a portfolio with a Sharpe Ratio of 7.28, based on an expected return of 25.27%, and a standard deviation of daily returns of 3.47%. From this, you should understand that BETA is > 1 when compared to the SPY (S&P 500 ETF) we use to calculate stock BETAs. Had we only included S&P 500 stocks, BETA would be 1.0, and expected returns would be 16.08%. The NASDAQ and Russell 2000 both outperformed the S&P 500 this past year.
In Phase 1, we run a series of classical analyses to select 119 stocks in an ‘allstar’ portfolio. In Phase 2, we take those 119 stocks and analyze them for the absolute best portfolios, using classical solvers and the D-Wave Systems Advantage 1.1 quantum annealing computer.
Our solvers for this run include Monte Carlo, Genetic Algorithm, Simulated Annealer, Particle Swarm Optimization, Simulated Bifurcator, TABU (multi-start), D-Wave Simulated Annealer, and the D-Wave Quantum Annealer.
In last night’s run, our simulated bifurcator could not find the best 150 stock portfolio. However, from the looks of these three charts, it might have been able to if we let it run longer (than the ~500 iterations in this run). Time was running short, and it was approaching 10pm. We did have good success in Phase 2, where our SBM selected an attractive 12-stock portfolio.
Lately we have invested in making our solvers work more quickly and efficiently. In many cases, these can be considered independent optimizers which together give us their best portfolios (based on the CQNS minimum score). When we see convergence between the solvers, it gives us greater confidence. Sometimes, we run solvers repeatedly, and more deeply, to force that convergence. We did that last night (e.g., we ran 2M Monte Carlo samples per portfolio size at the end to ‘give it time’ to find the best portfolio).
So, what happened is we picked three stocks and one was a bond. Ugh, we spent hours finding that the best combination of stocks was two risky stocks and a bond. $TVC and $TVE are the Tennessee Valley Authority PARRS. They are ‘putable’ $25 retail bonds where the interest rate can be reset at will by the TVA, and the retail investor can return the bond for $25 at any time. So, the price does not move very much, and it is based on interest rate swings and resets by the TVA. You can see the 5-day price action below, and see that it can trade like a stock. BTW, the rate reset down to ~2.2%, which cost each $25 bond about $0.75 in value.
Well, we cannot recommend two stocks and a bond! So, had to remove the $TVC and run Phase 2 again. The challenge was that the initial 119 stocks might have been influenced by the inclusion of $TVC, so we also added 31 incremental stocks that were selected in the 2nd and 3rd best portfolios. We were up to 150 stocks heading back into Phase 2.
We had a significant trade-off to make with this choice of 150 stocks. The D-Wave Advantage 1.1 can embed a maximum of ~160 fully-embedded vertices, or cliques (clique = stock). However, we have only ever successfully run 138 stocks on the D-Wave. By selecting 150 top stocks, we believe we had a better chance of selecting a great portfolio (from 150 ‘allstars’ instead of only 118), but we gave up the chance of running this one quantum.
Our Particle Swarm Optimizer (PSO) solver is also a new addition. In this run of 150 stocks, it picked a three-stock portfolio which selected two of the finalists, and added a third, new stock. It received a slightly worse CQNS score. FYI, we use Pyswarm in python to power our PSO.
Findings from our second Phase 2 run (150 stocks). We had concurrence and convergence across our solvers to the same three-stock portfolio, which had the best CQNS rating. Our Bespoke simulated annealer picked a four-stock solution with a slightly worse rating (it added a 4th stock), and we chose that portfolio for publication. There are still choices to make in selecting portfolios for our clients, or general population readers.
So, how did this portfolio perform on its first day? Pretty well.
A few notes:
We do not have a position in any of the stocks mentioned in this article, nor do we intend to initiate a position in the next 24 hours.
We like exchange-listed stocks (vs. OTC) because of the added liquidity, visibility and compliance protection they provide. BTW: this does not mean they will pay a dividend next year.
We add $KELYA to our tracking as $KELYB is thinly traded compared to $KELYA. Experienced investors would most likely want to hold $KELYA due to greater liquidity and price transparency through trading volume.
Update: So, how did we do? If you would have invested in those 4 stocks (equally weighted) on market open Jan 5, 2021, you would have earned 3.7% vs. an $SPY return of 0.3%. Returns were largely driven by D.R. Horton, Inc. and WIT. Kelly Services (A or B shares) were down, and SLGN was down, but only slightly.What is nice is the shape of the chart, where we see zig and zag, meaning offsetting moves that help an investor reduce their drawdown, or money lost (unrealized) from time of investment.
In summary, in the first 18 days of trading, you would have significantly outperformed the market with these dividend-paying stocks (gain of 3.7% vs. gain of 0.3%). It will be interesting to see how these do during the current market decline we are facing.
