Systematic Trading de Robert Carver

Systematic Trading

Autor Robert Carver
en Limba Engleză Hardback – 14 sep 2015

Majoritatea investitorilor consideră că succesul în piețele financiare depinde de intuiție sau de găsirea unei formule magice de prognoză; în realitate, cel mai mare obstacol în calea profitabilității este însăși biologia umană. Merită menționat că Systematic Trading nu este o simplă colecție de algoritmi, ci o metodologie riguroasă de disciplinare a procesului decizional. Reținem perspectiva autorului Robert Carver, care, după o carieră la vârful industriei de hedge funds, demonstrează că eliminarea erorilor sistematice și a intervențiilor emoționale este mult mai valoroasă decât încercarea de a prezice viitorul.

Subliniem modul în care această lucrare se poziționează în cadrul operei autorului: dacă Smart Portfolios se concentra pe alocarea activelor, iar Advanced Futures Trading Strategies pe tactici specifice, Systematic Trading reprezintă fundamentul filosofic și tehnic al întregului său sistem. Cartea este structurată progresiv, pornind de la eșecurile psihologice documentate în criza din 2008 și evoluând spre construcția unui „black box” care, surprinzător, este mult mai simplu decât s-ar aștepta un novice.

Cititorul care a aplicat ideile din A Guide to Creating A Successful Algorithmic Trading Strategy de Perry J. Kaufman va găsi aici elementul care lipsește adesea din ghidurile pur tehnice: un cadru robust de management al pozițiilor adaptabil în funcție de capital și costurile de tranzacționare. Spre deosebire de abordările care promit randamente triple, Robert Carver oferă o arhitectură open-source pentru investiții, punând accent pe supraviețuirea pe termen lung și pe controlul riscului, indiferent dacă tranzacționați acțiuni, obligațiuni sau instrumente derivate.

De ce să citești această carte

Această carte este esențială pentru traderii care doresc să treacă de la decizii bazate pe impuls la un proces bazat pe date și reguli clare. Veți învăța să construiți un sistem de tranzacționare personalizat care elimină subiectivitatea, optimizează dimensiunea pozițiilor și minimizează costurile inutile. Este instrumentul ideal pentru a transforma tranzacționarea dintr-o activitate stresantă într-o operațiune sistematică, profesională și controlată.

Despre autor

Robert Carver are o experiență de peste un deceniu în City-ul londonez, activând inițial ca trader de produse derivate exotice pentru Barclays. Ulterior, a fost manager de portofoliu la AHL, unul dintre cele mai mari fonduri de tip systematic hedge fund din lume, unde a gestionat strategii macro globale și portofolii de venit fix de ordinul miliardelor de dolari în timpul crizei financiare din 2008. Cu studii avansate în economie, Carver s-a retras din industria instituțională în 2013 pentru a-și gestiona propriile investiții folosind aceleași principii sistematice pe care le descrie în lucrările sale.

Descriere scurtă

This is not just another book with yet another trading system. This is a complete guide to developing your own systems to help you make and execute trading and investing decisions. It is intended for everyone who wishes to systematise their financial decision making, either completely or to some degree. Author Robert Carver draws on financial theory, his experience managing systematic hedge fund strategies and his own in-depth research to explain why systematic trading makes sense and demonstrates how it can be done safely and profitably. Every aspect, from creating trading rules to position sizing, is thoroughly explained. The framework described here can be used with all assets, including equities, bonds, forex and commodities. There is no magic formula that will guarantee success, but cutting out simple mistakes will improve your performance. You'll learn how to avoid common pitfalls such as over-complicating your strategy, being too optimistic about likely returns, taking excessive risks and trading too frequently. Important features include: - The theory behind systematic trading: why and when it works, and when it doesn't. - Simple and effective ways to design effective strategies. - A complete position management framework which can be adapted for your needs. - How fully systematic traders can create or adapt trading rules to forecast prices. - Making discretionary trading decisions within a systematic framework for position management. - Why traditional long only investors should use systems to ensure proper diversification, and avoid costly and unnecessary portfolio churn. - Adapting strategies depending on the cost of trading and how much capital is being used. - Practical examples from UK, US and international markets showing how the framework can be used. Systematic Trading is detailed, comprehensive and full of practical advice. It provides a unique new approach to system development and a must for anyone considering using systems to make some, or all, of their investment decisions.
