    "A Port­fo­lio Per­spect­ive on the Mul­ti­tude of Firm Char­ac­ter­ist­ics" (joint with Victor DeMiguel, Al­berto Martín-Utrera, Fran­cisco J.No­gales)

    Ab­stract: We in­vestig­ate which char­ac­ter­ist­ics mat­ter jointly for an in­vestor who cares not only about aver­age re­turns but also about port­fo­lio risk, trans­ac­tion costs, and outof- sample per­form­ance. We nd only a small num­ber of char­ac­ter­ist­ics|six|are sig­nic­ant without trans­ac­tion costs. With trans­ac­tion costs, the num­ber of signi cant char­ac­ter­ist­ics in­creases to 15 be­cause the trades in the un­derly­ing stocks re­quired to re­bal­ance dier­ent char­ac­ter­ist­ics often net out. We show in­vestors can identify com­bin­a­tions of char­ac­ter­ist­ics with ab­nor­mal out-of-sample re­turns net of trans­ac­tion costs that are not fully ex­plained by the Fama and French (2015) and Hou, Xue, and Zhang (2014) factors.

    "Why do mu­tual funds hold cash?”, co-au­thored with Chris­toph Sch­euch

    Ab­stract: We ar­gue that mu­tual funds hold li­quid as­sets at least par­tially to col­lect rents, a motive dif­fer­ent from li­quid­ity trans­form­a­tion. We pro­pose a parsi­mo­ni­ous model that in­cor­por­ates the ef­fects of trad­ing costs and li­quid­ity man­age­ment on fund flows. Fol­low­ing bad per­form­ance, man­agers com­pensated on fund size op­tim­ally re­duce il­li­quid in­vest­ment to max­im­ize fu­ture ex­pec­ted re­turns, pre­serving some liq- uid as­sets. Man­agers com­pensated on past per­form­ance, on the other hand, meet re­demp­tions by de­plet­ing li­quid as­sets first. However, be­cause of lower ex­pec­ted re­turns this only in­tens­i­fies the out­flow and destabil­izes the fund. Moreover, the use of cash for rent col­lec­tion is pre­ferred to higher man­age­ment fees, as it makes mu­tual funds less prone to li­quid­ity-driven with­draw­als. Over­all, we cau­tion not to in­ter­pret the ob­served bal­ances of li­quid as­sets in mu­tual funds as con­clus­ive evid­ence of the mag­nitude for li­quid­ity trans­form­a­tion these funds provide.

    "Ef­fi­ciently Inef­fi­cient Mar­kets for As­sets and As­set Man­age­ment"

    Ab­stract: We con­sider a model where in­vestors can in­vest dir­ectly or search for an as­set man­ager, in­form­a­tion about as­sets is costly, and man­agers charge an en­do­gen­ous fee. The ef­fi­ciency of as­set prices is linked to the ef­fi­ciency of the as­set man­age­ment mar­ket: if in­vestors can find man­agers more eas­ily, more money is al­loc­ated to act­ive man­age­ment, fees are lower, and as­set prices are more ef­fi­cient. In­formed man­agers out­per­form after fees, un­in­formed man­agers un­der­per­form after fees, and the net per­form­ance of the aver­age man­ager de­pends on the num­ber of "noise al­loc­at­ors." Small in­vestors should be pass­ive, but large and soph­ist­ic­ated in­vestors be­ne­fit from search­ing for in­formed act­ive man­agers since their search cost is low re­l­at­ive to cap­ital. Hence, man­agers with lar­ger and more soph­ist­ic­ated in­vestors are ex­pec­ted to out­per­form.
