Artemis: Why turnover can be a potent source of alpha

Key takeaways

  • We view turnover as a source of excess returns
  • Earnings revisions and changes to analysts’ forecasts drive a lot of the changes we make within our SmartGARP® funds, and for good reason
  • Switching stocks within sectors can add value without increasing risk 
  • Transaction costs are more than offset by the benefits of moving capital into companies with stronger fundamentals and growth prospects, but cheaper valuations

Turnover can be controversial. It is often equated with higher transaction costs and higher fees.

We see it differently. We think turnover can be a potent source of alpha. We also see it as an integral part of our SmartGARP investment process.

One of the eight factors our SmartGARP stock-screening tool measures is ‘revisions’, i.e. changes to analysts’ corporate earnings estimates. We want to own stocks whose profit forecasts are being revised upwards by the analyst community and avoid those being downgraded.

Across the SmartGARP European Equity Fund’s 25-year history, our revisions factor has proven to be the most effective at pointing us towards those companies that subsequently go on to deliver superior fundamental growth.

Analysts amend their earnings forecasts when companies report results, which in Europe is quarterly or every six months. This is the cadence at which companies’ revisions scores change within SmartGARP. So if we are to gain exposure to stocks seeing upgrades, we need to adjust our portfolios frequently.

For the Artemis SmartGARP European Equity Fund, our average holding period is about a year, but it has been as short as six months – or as long as two years. Turnover tends to be higher when markets experience seismic change, such as during the Covid pandemic or the Global Financial Crisis. But even a two-year holding period is probably shorter than many of our peers.

The merits of moving on 

Owning stocks where the relative fundamentals are improving is important. But so is selling out of positions where fundamentals are weakening. This sounds simple enough. 

Yet behaviourally, jettisoning stocks is not easy for many fund managers. If a company has made your clients a lot of money you might be inclined to trust it will keep delivering. And if an investment has not worked out, it’s hard to admit you made a mistake. (Perhaps you were right all along and it will eventually come good…) This is why having a proven, systematic, data-driven process is helpful when it comes to pulling the trigger. 

 If a stock gets downgraded, we trust the data and our process. We don’t wait around to see what happens. 

We don’t try to be heroes. We get out, move on, and either cut our losses or take profits.

Relative value trades 

One of the ways in which we have added value over the years is by switching stocks within sectors, continually moving towards where we see the best risk/reward trade-off.  

For example, we took profits in Novartis earlier this year and bought Sanofi instead. The two healthcare stocks have similar industry, currency and economic sensitivity, but SmartGARP showed us that Sanofi had a more attractive valuation and growth rate. 

Over the past decade, Novartis’ earnings relative to the European stock market have grown by 50% (the green line in the chart below) and its share price has increased as a result (the blue line). By the start of this year, it was trading at a slight premium to the market and its earnings growth had started to slow, so we sold out. Sanofi, by contrast, is trading at a significant discount to the market and has stronger earnings.

As the facts changed, we changed our portfolio. Making that change incurred a modest fee (transaction costs and commissions have come down a long way in recent years). But this strategy’s history suggests transactions like these deliver value to our clients significantly in excess of the charges they incur.

Is turnover adding value?  

Our fund has performed well over the long term because our process steers us towards stocks that subsequently outgrow the market. The vast majority of our returns since inception (88%) have come from stock selection rather than country or sector decisions1

That matters in the context of turnover because stock selection is not a one-off decision. The financial characteristics that make a company attractive can change as market conditions, valuations and earnings expectations evolve. Ensuring the fund continues to hold companies with attractive characteristics, those that are cheap and growing faster than the market, means the portfolio needs to evolve as facts change. 

Over the past five years to 30 June 2026, stocks bought by the fund returned 19.7% in the 12 months after purchase, while stocks sold returned -3.6% in the 12 months after sale2. That is a 23.3 percentage point spread between what we bought and what we sold. So there would have been a significant opportunity cost had we not traded.  

Standing pat would have prevented us from recycling capital into more attractive opportunities.

Over the same five-year period, the fund achieved an annualised return of 19.8% compared to 10.6% for its benchmark, the FTSE World Europe ex UK index, and 8.0% for the IA Europe Excluding UK sector3.  

During this time, the fund outperformed in 63% of months, with a 68% hit rate in up markets and a 55% hit rate in down markets4. At the individual stock level, the hit rate was close to 50%, which is an important point: successful active management does not require every stock decision to be right. It requires a process that sizes opportunities sensibly, cuts deteriorating positions and allows the better ideas to contribute more than the mistakes detract. 

Continually refining the portfolio and ensuring that it owns companies with the most compelling financial characteristics is integral to a process that has delivered market-beating returns over the course of 25 years. For us, buying and selling is a fundamental part of being an active investor.
