A dynamic scenario‐driven technique for stock price prediction and trading. (25th January 2022) - Thesia, Yash
Abstract: It has always been a challenge to accurately forecast the behavior of a stock market due to its extremely nonlinear and dynamic nature. Numerous studies have shown that technical indicators describing stocks in conjunction with machine learning models can serve as useful tools for forecasting in the stock market. There are various challenges, and one of them is the choice of the right technical indicators and prediction models. It is believed that there is no optimal set of technical indicators that work well in all market scenarios in a dynamic environment such as the stock market. The statement also applies to different prediction models. There is no definite winner, and different settings can emerge as winners in different market scenarios. On this premise, we propose DSdT: a dynamic scenario‐driven technique for stock price prediction and trading strategy enhancement. The proposed novel technique uses the scenario recognition and integration module to identify and integrate the current market scenario into the forecasting pipeline, resulting in a scenario‐driven stock price prediction. We use a large set of technical indicators and a shallow neural network equipped with a gating mechanism to capture and integrate the current market scenario in the prediction process. Experiments are performed on 11 stocks of the Indian Stock Market. The proposed approach yields mean absolute percentage error (MAPE) of 1.67 % compared with 2.4 % of its closest nonscenario‐driven counterpart for the next day's stock price prediction task. A trading strategy is also devised using the proposed technique, and the returns are compared with different baselines. Results show that the devised trading strategy yields an approximate average return of 54 % compared with 25 % of the return obtained by the nearest benchmark.
