News sentiment turns mildly bearish for Nifty: Heckyl

Posted on

Heckyl Sentiment index, which reflects a broad reading of collective sentiment for the Nifty companies, has turned mildly bearish for the 50-share index ending 2-month long bullish phase. Media sentiment for the broad-based index was in the bullish territory since the start of earnings season in April this year. The recent rate hike by the US Federal Reserve and selloff in technology shares weighed on the sentiment.

Heckyl Technologies, a leading fin-tech company in news and financial data analytics, has recently introduced Sentiment index to gauge perceptions about the Indian stock markets. Sentiment Index leverages Heckyl’s news and sentiment analysis capabilities. Heckyl distils massive amounts of news data and then analyses its potential impact on the stock prices in real-time.

We have used the crossover of fast and slow moving averages of sentiment score to quantify media perception. Bullish and bearish signals are generated when two averages cross each other.

Bullish Signal:
When short-term sentiment (30-day average) rises above long-term (90-day average), green shading indicates likely uptrend for the Nifty.

Bearish Signal:
When short-term Sentiment (30-day average) falls beneath long-term (90-day average), pink shading indicates likely downtrend for the 50-share index.

Heckyl sentiment score showed extreme pessimism for major IT companies within the Nifty. Indian IT sector has been reeling under pressure on concerns US President Donald Trump’s clampdown on visas, layoffs and automation may impact software exporters.


On the other hand, sentiment for major banking stocks in the 50-share index has been bullish since April 2017. The central bank’s crackdown on bad debt has fueled optimism in the banking sector. Recently the Reserve Bank of India (RBI) has directed banks to start bankruptcy process against 12 large loan defaulters to reduce NPA levels and thereby improve asset quality of lenders.


Key Observations of Sentiment Index Backtesting:
Heckyl has backtested 4-years’ data from Jun. 24, 2013 to Jun. 23, 2017 to find out whether Sentiment Index is a better indicator for the Nifty or not. We have found a very strong correlation between Sentiment Index and Nifty. Correlation between Sentiment 90-day average and the Nifty stood at 0.87 for the past 4-years, indicating a strong uphill relationship. Meanwhile, correlation between Sentiment 30-day average and Nifty Index was 0.76, signaling a strong positive relationship. It is evident from such a high level of correlation that Heckyl Sentiment index is a better indicator for the Nifty.

Note: Correlation value lies in between +1 (perfect positive) and –1 (perfect negative)

The Bottom-line:
Overall sentiment in the economy is buoyant as India is heading for the rollout of GST, the biggest tax reform in the country, from July 1. The market has already factored in the introduction of GST and its likely impact on the economy. Currently, the benchmark indices are trading at a lifetime high. On the other hand, media coverage has shown mildly bearish sentiment for the Nifty. It remains to be seen whether recent shift in sentiment will last long or it is a temporary phenomenon. A lot will depend on how the news flow will be for second quarter earnings season in the next month.
