Heckyl has developed FiND sentiment moving average (MA) strategy for measuring the potential impact of the positive/ negative news flow on the value of equities in real-time. The sentiment MA strategy indicates bullish/bearish signals based on the crossover of fast and slow moving averages of the company’s daily sentiment score.
We back-tested our sentiment MA strategy on 27 companies (excl. banks) from Straits Times index (STI). Our back-testing has proved the potential of sentiment MA strategy to beat STI companies’ stock price performance.
If an investor/a trader was to buy/sell STI stocks as per the bullish/bearish signal and hold the position for the period till the signal reverses, then an equal investment in 27 STI stocks could have yielded 6.3% return over the past 1-year (as against 0.3% price return).
