10 of the best performing UK-listed stocks right now

"You don't need to be a rocket scientist [to invest]," - Warren Buffett. This simple strategy shows why.

"You don’t need to be a rocket scientist. Investing is not a game where the guy with the 160 IQ beats the guy with 130 IQ." 
— Warren Buffett

Another day, another Warren Buffett quote... He's right though. Successful investing can be relatively simple. Nowhere is this more obvious than in the persistent outperformance of relative strength (RS) strategies, where investors buy companies that have outperformed the wider market over a set period of time.

Imagine: investor A gets home from work, studiously notes up financial statements, trawls through the footnotes, follows the cash flows, makes the adjustments, finds the value, and places his bets. Investor B wakes up, turns on her computer, and simply buys what's gone up recently.

The evidence over the years suggests Investor B's portfolio is likely to motor ahead.

No surprise then, that Stockopedia's Price Momentum Screen is one of the top-performers over multiple timeframes. The screen is up 45% over two years and has staged a strong recovery so far in 2019, up nearly 25% since the start of January.

The screen itself is as simple as they come: take companies with positive six-month and one-year relative strengths and a negative one-month relative strength, and then sort the results in descending order of one-year relative strength. Investor B would be proud.

Here are the top 10 companies with the strongest one-year relative strength and a market cap of over £100 million:

Name Market cap RS 1yr RS 6m RS 1m Sector
Eco (Atlantic) Oil & Gas (LSE:ECO) 162.4 +141.3 +81.2 -15.7 Energy
Serica Energy (LSE:SQZ) 355.2 +128.8 +7.35 -0.65 Energy
AB Dynamics (LSE:ABDP) 537.9 +119.2 +51.9 -2.98 Consumer Cyclicals
Churchill China (LSE:CHH) 167.5 +65.0 +47.4 -2.59 Consumer Cyclicals
Marshalls (LSE:MSLH) 1,309 +61.8 +31.7 -1.48 Basic Materials
San Leon Energy (LSE:SLE) 176.1 +61.3 +45.3 -4.19 Energy
Coca-Cola European Partners (LSE:CCEP) 21,172 +56.9 +15.5 -0.25 Consumer Defensives
IFG Group (LSE:IFP) 198.1 +55.7 +28.5 -1.13 Financials
4imprint (LSE:FOUR) 727.4 +51.4 +26.2 -4.41 Consumer Cyclicals
Alpha FX (LSE:AFX) 297 +50.4 +29.3 -2.18 Financials

One thing to note about this screen is that, depending on the conditions, the very fastest moving stocks can sometimes be speculative and unpredictable. As a result, you can see slightly more exotic small-cap energy and technology names at times. But it can also pick up fast-moving, higher-quality plays as well. Some of those currently include stocks like AB Dynamics, Churchill China and 4imprint.

So, it's no surprise that relative strength is a measure that's appealed to some very successful investors over the years...

The legendary British investor Jim Slater generated 'spectacular' results by using relative strength in conjunction with his signature PEG ration (price/earnings-to-growth) and a price-to-cash flow measure in Beyond the Zulu Principle. Over a six-month sample period, his relative strength screen returned +34.5%, compared to +21.6% for his cash flow and low PEG screen, and just +8.9% for the market as a whole.

Jim O'Shaughnessy, meanwhile, documented his comprehensive study of factor strategies over a 44-year sample period in What Works on Wall Street. He found that not only was relative strength "among the only pure growth factors that actually beats the market consistently, and by a wide margin," but that "each of the ten best-performing strategies... includes relative strength criteria.

How to use relative strength effectively

High relative strength stocks do tend to have persistent positive momentum, especially over six and 12-month periods, but this is not a guarantee of success over these time frames. When high momentum stocks falter, the downside can be dramatic. A degree of emotional fortitude is required to weather share price volatility when a stock's direction of travel changes for the worse.

In fact, the study on which this screen is based found that, although top decile relative strength portfolios outperformed over six and 12-month periods, they went on to underperform in subsequent periods. Quarterly, semi-annual, or annual rebalancing of the portfolio might be one way to avoid the prospect of flagging momentum stocks.

Going back to Jim O'Shaughnessy's multi-strategy study of stock returns over a 44-year period in What Works on Wall Street, the American investor writes: "[Relative strength criteria in the 10 best-performing strategies] are always tied to another factor, usually one requiring the stocks to be modestly priced in terms of how much you are paying".

Over six-month and 12-month periods, winners generally continue to win and losers generally continue to lose. When it comes to adding momentum to your portfolio relative strength is a powerful tool - but it is best used in conjunction with some simple relative valuation measures such as the price-to-sales ratio or a composite Value Rank.
