To be able to detect what is abnormal, it is necessary to know what is normal."* * Jan Mossin, Markedseffisiens (Market efficiency), TANO, 1986 The Institute for Quantitative Research in Finance, Spring 2007 Seminar KNK 260307 WWW.NBIM.NO 30 Norges Bank Investment Management Textbook Approach to Active Portfolio Management • Active management is a process. Active management begins with raw information, refines into forecasts, and then optimally and efficiently constructs portfolios balancing those forecasts of return against risk • Active management is forecasting, and a key to active management performance is superior information • Active managers should forecast as often as possible (the fundamental law) • Mathematics cannot overcome ignorance/lack of information R.C.

Can afford large investments in systems Low commissions. Our flow has value Low trading costs gives more opportunity for applying quant strategies Size and organizational skills gives power to demand and build new products with service providers, like: Custodians, prime brokers, prime custody, backoffice Size advantage in securities lending 24/7 systems and organization The Institute for Quantitative Research in Finance, Spring 2007 Seminar KNK 260307 WWW.NBIM.NO 48 Norges Bank Investment Management The Advantage of Size (2) • Access to company information; scale advantage in some research, easier access to the global talent pool • Some lower fees in external management • Top credit rating; balance sheet advantages • Some studies indicates a positive relation between alpha and size (next two slides) The Institute for Quantitative Research in Finance, Spring 2007 Seminar KNK 260307 WWW.NBIM.NO 49 Norges Bank Investment Management Large funds did better than small funds. • On average, the Net Value Added was higher by 28 bps for a $1 billion fund Net Value Added versus Size (log10) compared with a $100 million fund.

(Trading costs may eat to much of the alpha return. But as explained, we try to build trading into an advantage) • May have constraints in external active management • Lack of scalability in some of the internal alpha strategies. May be difficult to keep the return targets? • May a fat and complacent organization follow with increased size? The Institute for Quantitative Research in Finance, Spring 2007 Seminar KNK 260307 WWW.NBIM.NO 52 Norges Bank Investment Management Discussion • Yes, it is possible to become to big, but we are still not there • When there is one owner of the assets; by splitting in different portfolios, there is a risk for ending up with costly index management (overlap that average out active positions) • Better way of splitting up: Keep the beta and transition machines, set up different & focused alpha satellites • Avoiding being fat & complacent: Line structure with real delegation, results having effect on compensation and position for everybody, outsourcing of all activities that are not in the core business, individual measurement The Institute for Quantitative Research in Finance, Spring 2007 Seminar KNK 260307 WWW.NBIM.NO 53
