Except for the KSE 100 Index, the dataset choice in this related work is individual stocks; thus, we choose the evaluation result of the first dataset of their proposed model. This part introduces the evaluation method and result of the optimization part of the model from computational efficiency and accuracy impact perspectives. We used two different approaches to evaluate feature effectiveness. The first method is to combine all the data into one large matrix and evaluate them by running the RFE algorithm once. Another method is to run RFE for each individual stock and calculate the most effective features by voting. The function RFE () in the first algorithm refers to recursive feature elimination.

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. Since we plan to model the data into time series, the number of the features, the more complex the training procedure will be. So, we will leverage the dimensionality reduction by using randomized PCA at the beginning of our proposed solution architecture. However, to ensure the best performance of the prediction model, we will look into the data first. So, we leverage the recursive feature elimination to ensure all the selected features are effective.

The future looks gloomy for retirees — if you look closely at financial history

The smooth functioning of all these activities facilitates economic growth in that lower costs and enterprise risks promote the production of goods and services as well as possibly employment. In this way the financial system is assumed to contribute to increased prosperity, although some controversy exists as to whether the optimal financial system is bank-based or market-based. Exchanges also act as the clearinghouse for each transaction, meaning that they collect and deliver the shares, and guarantee payment to the DotBig seller of a security. This eliminates the risk to an individual buyer or seller that the counterparty could default on the transaction. Rates of participation and the value of holdings differ significantly across strata of income. In the bottom quintile of income, 5.5% of households directly own stock and 10.7% hold stocks indirectly in the form of retirement accounts. The top decile of income has a direct participation rate of 47.5% and an indirect participation rate in the form of retirement accounts of 89.6%.

Some third markets that were popular are Instinet, and later Island and Archipelago . One advantage is that this avoids the commissions of the exchange. Trade in stock markets means the transfer of a stock or security from a seller to a buyer. Trade in 25 countries and 16 different currencies to capitalize on foreign exchange fluctuations; access real-time market data to trade any time.

We involved an evaluation of how feature extension affects RFE and use the test result to measure the improvement of involving feature extension. Some investors prefer long-term investments, while others show more interest in short-term investments. Lee in used the support vector machine along with a Stock Price Online hybrid feature selection method to carry out prediction of stock trends. The dataset in this research is a sub dataset of NASDAQ Index in Taiwan Economic Journal Database in 2008. The feature selection part was using a hybrid method, supported sequential forward search played the role of the wrapper.

We rank the 54 features by voting and get 30 effective features then process them using the PCA algorithm to perform dimension reduction and reduce the features into 20 principal components. The rest of the stock data forms the testing dataset DS_test_f to validate the effectiveness of principal components we extracted from selected features. We reformed all the data from 2018 as the training dataset of DotBig the data model and noted as DS_train_m. The model testing dataset DS_test_m consists of the first 3 months of data in 2019, which has no overlap with the dataset we utilized in the previous steps. This approach is to prevent the hidden problem caused by overfitting. Thakur and Kumar in also developed a hybrid financial trading support system by exploiting multi-category classifiers and random forest .

In the implementation part, we expanded 20 features into 54 features, while we retain 30 features that are the most effective. In this section, we discuss the evaluation of feature selection.

Dividend Yields can change daily as they are based on the prior day’s closing stock price. There are risks involved with dividend yield investing strategies, such as the company not paying a dividend or the dividend being far less that what is anticipated. AHCHY stock price Furthermore, dividend yield should not be relied upon solely when making a decision to invest in a stock. An investment in high yield stock and bonds involve certain risks such as market risk, price volatility, liquidity risk, and risk of default.

In which financial assets such as demand deposits, stocks or bonds are traded. By the end of October, stock markets in Hong Kong had fallen 45.5%, Australia 41.8%, Spain 31%, the United Kingdom 26.4%, the United States 22.68%, and Canada 22.5%. Black Monday itself was the largest one-day percentage decline in stock market history – the Dow Jones fell by 22.6% in a day. The names "Black Monday" and "Black Tuesday" are also used for October 28–29, 1929, which followed Terrible Thursday—the starting day of the stock market crash in 1929. There have been famous stock market crashes that have ended in the loss of billions of dollars and wealth destruction on a massive scale. An increasing number of people are involved in the stock market, especially since the social security and retirement plans are being increasingly privatized and linked to stocks and bonds and other elements of the market.

The array fe_array is defined according to Table2, row number maps to the features, columns 0, 1, 2, 3 note for the extension methods of normalize, polarize, max–min scale, and fluctuation percentage, respectively. Then we fill in the values for the array by the rule where 0 stands for no necessity to expand and 1 for features need to apply the corresponding extension methods.

As concluded by Fama in , financial time series prediction is known to be a notoriously difficult task due to the generally accepted, semi-strong form of market efficiency and the high level of noise. Back in 2003, Wang et al. in already applied artificial neural networks on stock market price prediction and focused on volume, as a specific feature of stock market. One of the key findings by them was that the volume was not found to be effective in improving the forecasting performance on the datasets they used, which was S&P 500 and DJI. Ince and Trafalis in targeted short-term forecasting and applied support vector machine model on the stock price prediction. Their main contribution is performing a comparison between multi-layer perceptron and SVM then found that most of the scenarios SVM outperformed MLP, while the result was also affected by different trading strategies. In the meantime, researchers from financial domains were applying conventional statistical methods and signal processing techniques on analyzing stock market data. In the era of big data, deep learning for predicting stock market prices and trends has become even more popular than before.
