Quantitative Researcher, Intern
o Initiated and developed two quantitative strategies based on python and R, including a stock strategy for ZZ500 and HS300 stock pools and an options strategy for 50ETF in Chinese stock and options market.o In the stock strategy, I adapted the multi-factors method with three fundamental factors like the return of equity and one technical factor and computed the weighted average of the ranks of the factor values in different industries to evaluate the stocks. Moreover, I set different capital for selected stocks based on the market capital percentage of their industries in the whole stock market in order to diversify risk. This strategy performed a 20%+ annual rate of return with 5%- max drawdown on 1-year historical data.o In the option strategy, I applied the arbitrage method based on the convexity of the option price. On 1-year historical data, there were 100+ possible opportunities for this kind of arbitrage, especially when the price of underlying assets fluctuated violently.
