Providing excellent support to clients should inevitably be at the top of any sell-side priority list. Moving on to Fig 2, which examines the priorities for the buy-side when using a trading algorithm, we can see that execution consistency is seen as the most vital component. This comes as little surprise as getting consistent execution is surely the reason to use an al- gorithm over a sales trader anyway. However, this has notably increased in importance for the buy-side with 14.29% of respondents saying this was their priority when using algorithms, up from 11.37% in 2016. As alluded to above, this may be due to a greater focus on execution quality by both regulators and end investors and being able to achieve consistent results is crucial to benchmark and judge the quality of each individual algorithm and each provider. Mirroring our global algorithmic trading survey, ease-of-use also continues to be a major factor for algo users with 13.61% saying this was a reason for using algorithms, and the reasons are likely to be much the same. The level of technology available to buy-siders has become far more sophisticated in recent years as has borrowing user interface ideas from the consumer software sector. Clunky, ugly and complex interfaces seen in older proprietary systems are increasingly unattractive and inefficient for buy-side firms who expect a much sleeker experience. One word of warning for the Asian algo community however is that both in 2017 and historically, the areas where they scored highest, customer support and execution consulting, are fairly low on the priority list for asset managers. Execution consulting in particular 70 TheTrade Winter 2017 was seen as a priority by just 4.08% of respondents, while 6.12% mentioned customer support. It will be interesting to see if this changes as the focus on best execution increases or whether the high scores in this area are sufficient to mean that buy-side firms do not see this as a major concern when selecting provider as they already believe performance is good. When looking at the average number of providers the buy-side are using seen in Fig 3, the recent trend of declining broker lists among larger firms seem to have reached a resting point, with the largest asset man- agers (those with $50 billion or more of assets under management) levelling out at an average of 3.8 after having fallen for several years. This mirrors a similar trend seen in the rest of the world. Not surprisingly we see the number of brokers used increasing alongside AUM. This has become a more pronounced trend in recent years and now shows a much heavier correlation than in the past. Given there have been reports this year that brokers are streamlin- ing their client lists, focusing more on the biggest asset managers who are more profitable at a time when bank trading desks are squeezed. We expect this will continue post-MiFID II as more brokers look to max- imise profitability and make their broking business sustainable. Fig 4 shows a slightly different angle on this issue by looking at the percentage of respondents using differ- ent numbers of brokers. Notably the top and bottom ends are the largest here, with 20.75% of respondents using just one provider and over 30% using five or more. Those firms using just a single broker are of concern as such behaviour seems to fly in the face of the concept of best execution and could become a very serious problem if regulators begin to take a tougher line on this issue.
