Sentiment Moving Average

Introduction

Technical Analysis is the process of using charts and indicators based on the price and volume to predict the future movements of financial assets.

Technical Analysis bears similarities with Sentiment Analysis as Technical Indicators can be used to guess the opinions of other investors through their actions. For example, a large volume with increasing price could signify that the investors are largely positive and bullish about the asset. 

As such, Technical Indicators is a proxy for Sentiment Analysis.

This report will aim to show that incorporating Sentiment Analysis with Technical Analysis will improve the performance of a simple trading strategy.

Strategies to be Compared

The following 2 strategies will be used in this report:

 

Strategy A

Strategy B

If (5-day SMA[1] > 10-day SMA)

    Long Asset

Else

    Short Asset

If (5-day SMA > 10-day SMA)

    If (2-day Average Sentiment[2] > A1)

        Long Asset

    Else if (2-day Average Sentiment < A2)

        Close Position

Else

    If (2-day Average Sentiment < B1)

        Short Asset

    Else if (2-day Average Sentiment > B2)

        Close Position



[1] SMA refers to the Simple Moving Average. A n-day SMA is the arithmetic average of the closing prices of n successive trading days

[2] A 2 day average is used to smooth out noise which could cause the strategy to change positions constantly

The basis of both strategies is when the short term (price) moving average is above the long term (price) moving average, the asset price is in an upward path. Hence, we want to follow the trend and long the asset. Conversely, we want to short the asset in the other case.

The difference between the strategies is that B has additional entry and exit conditions if the sentiment moving average data does not agree with the (price) moving average condition.

It is obvious that Strategy A will always have open positions whereas Strategy B will occasionally have no positions, instead holding cash until another opportunity arises.

Testing Methodology

Sentiment data from the FinSentS API will be used for the comparison of the 2 strategies. A1, A2, B1, B2 are selected to be 5, 4, 6, 7 respectively for Strategy B.

For the asset, Apple Inc. (AAPL) is used.

When either Strategy enters a position, the position size will be equal to 90% of the portfolio’s value. This is to simulate the leaving of some cash holdings to prevent for margin calls.

Backtest

The backtest is carried out on the Quantopian Platform over the period 1/1/2016 – 11/5/2017.
