Did Fund Size Matter to Performance in 2015?

When a fund gets significantly larger it can mean that it is increasingly difficult to generate meaningful outperformance from individual security selection

2015 saw the two largest funds in the UK market enjoy very different fortunes. Continued strong inflows into SLI Global Absolute Return Strategies (GARS) added £2.6 billion into the UK version fund to November, which saw its assets rise to £26.8 billion, with total assets in the strategy now totalling over £44 billion. In contrast M&G Optimal Income saw net outflows to November of £6.2 billion and its assets decline to £16.3 billion.

GARS’ performance of 2.2% in 2015 was below its three-year average rolling target return of Cash +5% gross of fees, but nevertheless was a reasonable outcome in a tricky year for financial markets – the inflows came on the back of delivering good performance over previous years whilst staying within its volatility target of 4-8%. For Optimal Income however, disappointing performance in 2014 relative to its Morningstar category and a decline of 1.2% in 2015, along with increasing investor concerns about future returns from bond funds as the Federal Reserve moved closer towards raising interest rates, have come at the same time.

For both funds, size has meant that it is increasingly difficult to generate meaningful outperformance from individual security selection, which was a feature in the early days of both funds. However both funds seek to deliver returns from a wide variety of sources of alpha, which are generally asset-allocation and top-down in nature. Even though both funds appear to be very large, given their aims to trade in the money, bond and equity markets all over the world and their ability to use derivatives to efficiently manage exposures, we don’t think liquidity is as pressing an issue as it might seem. M&G’s recent disappointing performance was mostly due to its underweight stance on duration in its bond holdings. This stance could be reversed quickly through the use of derivatives even for a large fund like Optimal Income.

If there were an impact of size on fund performance, the expectation would be that relative performance would deteriorate over time as funds become more unwieldy to run. Where issue selection or rapid trading of less liquid securities is key to a fund’s success, this is a common scenario. However, there is also the notion of “reflexivity”, whereby a large fund that starts to see outflows is forced to sell down its largest positions which damages the prices and performance of the rest of the portfolio. This can also work positively as funds seeing inflows buy more of their favourite positions, so boosting prices and performance.

In most categories, the fund universe is highly fragmented and UK funds are small relative to their market liquidity. In addition, funds that are long term investors in the companies they invest in and thus have low portfolio turnover are able to cope with large size much more easily than funds with high rates of portfolio turnover, as they demand less liquidity. If a fund’s strategy is contrarian in nature, it may also be a liquidity provider—selling when others are buying and vice versa—allowing it to run at a greater scale than would otherwise be the case.

What of the UK Equity Income Sector?

The largest active UK equity funds are the Invesco Perpetual High Income and Invesco Perpetual Income funds, now managed by Mark Barnett, following the departure of Neil Woodford in 2014, at £12.6 billion and £6.5 billion respectively and Neil Woodford’s new fund CF Woodford Equity Income at £8 billion. All three of these funds performed well in 2015 and the Woodford fund performed exceptionally well, with performance of 16.2%, whilst dealing with inflows of £2.9 billion over the year. 

The largest contributors to the excellent performance of the Woodford fund were the exposures to healthcare and tobacco, two themes in which he has been invested for well over a decade. At year end he held a 7% position in Imperial Tobacco, which rose by 33% in 2015 and was the largest single contributor to the performance of the FTSE All Share index. A further 3.5% position was held in Reynolds American, which rose in value by 56% in 2015.

The healthcare exposure performed well on the back of much smaller or unlisted holdings. Woodford has run enormous amounts of money for some years now, but his excellent stock-picking and low-turnover style has meant that he has been able to deliver strong performance despite the size of his portfolios.

Mark Barnett‘s approach has been slightly different to that of Woodford – he is less inclined to hold unlisted companies and tends to hold smaller positions in his most favoured stocks. Whilst his funds saw heavy outflows in 2014 after Woodford left Invesco Perpetual, these tempered over 2015 as investors have seen him continue to deliver good performance. The performance in 2015 of 9.3% for the High Income fund and 8.4% for the Income fund, were comfortably ahead of the benchmark index and sector peers, and this followed very good performance in 2014. The size of his funds and his similar low-turnover style has not led to any difficulties in generating excellent performance.

Small Companies Funds Continue to Outperform

The sector which would be naturally least liquid and where size could quickly prove to be a handicap for managers is UK Smaller Companies. However, in 2015 the two largest UK smaller companies funds, SLI UK Smaller Companies and Marlborough Special Situations, both of which ended the year over £1 billion in size, delivered 28.2% and 19.2% respectively, strongly ahead of both the benchmark and the category average. Many funds outperformed their smaller companies’ benchmarks last year, where the resource-related stocks performed very poorly but many domestic industrial stocks performed very well.
