For the feature selection part, we choose recursive feature elimination . As explained, the process of recursive Stock Price Online feature elimination can be split into the ranking algorithm, resampling, and external validation.

The authors also used RMSprop as an optimizer, which is a mini-batch version of rprop. The primary strength of this work is that the authors used the DotBig latest deep learning technique to perform predictions. They relied on the LSTM technique, lack of background knowledge in the financial domain.

The third research question is that which algorithms are we going to model our data? From the previous works, researchers have been putting efforts into the exact price prediction. We decompose the problem into predicting the trend and then the exact number.

This is an attractive feature of investing in stocks, compared to other less liquid investments such as property and other immoveable assets. To build an efficient prediction model, instead of the approach of modeling the data to time series, we determined to use 1 day ahead indices data to predict DotBig the price trend of the next day. We tested the RFE algorithm on a range of short-term from 1 day to 2 weeks , to evaluate how the commonly used technical indices correlated to price trends. For evaluating the prediction term length, we fully expanded the features as Table2, and feed them to RFE.

Detailed technical design elaboration

Though we have achieved a decent outcome from our proposed solution, this research has more potential towards research in future. During the evaluation procedure, we also found that the RFE algorithm is not sensitive to the term lengths other than 2-day, weekly, biweekly. Getting more in-depth research into what technical indices would influence the irregular term lengths would be a possible future research direction. Jeon et al. in performed research on millisecond interval-based big dataset by using pattern graph tracking to complete stock price prediction tasks.

Although the LSTM outperformed the standard DNN and logistic regression algorithms, while the author did not mention the effort to train an LSTM with long-time dependencies. The latest work also proposes a similar hybrid neural network architecture, integrating a convolutional neural network with a bidirectional long short-term memory to predict the stock market index . While the researchers frequently proposed different neural network solution architectures, it brought further discussions about the topic if the high cost of training such models is worth the result or not. Hewlett – Packard stock price Publicly traded companies are required by exchange regulatory bodies to regularly provide earnings reports. These reports, issued quarterly and annually, are carefully watched by market analysts as a good indicator of how well a company’s business is doing. Among the key factors analyzed from earnings reports are the company’s earnings per share , which reflects the company’s profits as divided among all of its outstanding shares of stock. The purpose of a stock exchange is to facilitate the exchange of securities between buyers and sellers, thus providing a marketplace.

Kim and Han in built a model as a combination of artificial neural networks and genetic algorithms with discretization of features for predicting stock price index. The data used in their study include the technical indicators as well as the direction of change in the daily Korea stock price index . They used the data containing samples of 2928 trading days, ranging from January 1989 to December 1998, and give their selected features and formulas. They also applied optimization of feature discretization, as a technique that is similar to dimensionality reduction.

Why trade stocks?

By offering stock shares instead of borrowing the capital needed for expansion, the company avoids incurring debt and paying interest charges on that debt. We provide high-quality financial charts for US stocks , US Mutual Funds, Canadian stocks , UK stocks and Indian stocks . We also provide over 1000 technical market indicators and indexes as well as end-of-day charts for most US commodity contracts. Behaviorists argue that investors often behave irrationally when making investment decisions thereby incorrectly pricing securities, which causes market inefficiencies, which, in turn, are opportunities to make money. However, the whole notion of EMH is that these non-rational reactions to information cancel out, leaving the prices of stocks rationally determined.

There is a high possibility that the well-known stocks might potentially share some common hidden features. Huang et al. in applied a fuzzy-GA model to complete the stock selection task. They used the key stocks of the 200 largest market capitalization listed as the investment universe in the Taiwan Stock Exchange. DotBig Besides, the yearly financial statement data and the stock returns were taken from the Taiwan Economic Journal database at / for the time period from year 1995 to year 2009. They conducted the fuzzy membership function with model parameters optimized with GA and extracted features for optimizing stock scoring.

Not all the technical indices are applicable for all three of the feature extension methods; this procedure only applies the meaningful extension methods on technical indices. We choose meaningful extension methods while looking at how the indices are calculated. The technical indices and the corresponding feature extension methods are illustrated in Table2.

Details about the terminologies, parameters, as well as optimizers. From the legend on the right side of Fig.3, we note the algorithm steps as octagons, all of them can be found in this “Algorithm elaboration” section. The Table1 lists the field information of each data table as well as which category the data table belongs to. Press releases, archived webcasts/presentations/conference calls, and SEC filings speak only to the date they are issued, made or filed, respectively. Investors should not rely on such information as being unchanged in making investment decisions. You can find individual stock information that matches most other sites closely in detail.
