Can you actually predict the stock market?

Whoever figures out how to predict the stock market will get rich quick. Unfortunately, the market's ups and downs ultimately depend on the choices of a massive number of people—and you don't know what they're thinking about before they decide to buy or sell a stock.

What is the best model to predict stock prices?

One method for predicting stock prices is using a long short-term memory neural network (LSTM) for times series forecasting.

What is the most accurate stock predictor?

The MACD is the best way to predict the movement of a stock.

Can machine learning predict stock prices?

The machine learning model assigns weights to each market feature and determines how much history the model should look at to predict future stock prices.

How do you tell if a stock will go up or down?

If the price of a share is increasing with higher than normal volume, it indicates investors support the rally and that the stock would continue to move upwards. However, a falling price trend with big volume signals a likely downward trend. A high trading volume can also indicate a reversal of trend.

Which algorithms can predict stock price?

Support Vector Machines (SVM) and Artificial Neural Networks (ANN) are widely used for prediction of stock prices and its movements. Every algorithm has its way of learning patterns and then predicting.

How do you know if a stock will go up the next day?

After-hours trading activity is a common indicator of the next day's open. Extended-hours trading in stocks takes place on electronic markets known as ECNs before the financial markets open for the day, as well as after they close. Such activity can help investors predict the open market direction.

How often are stock predictions correct?

History of the January Barometer “The barometer… has proven correct in 20 of the last 24 years… Very few stock market indicators show such an 83.3 percent accuracy for even short spans of time.”

Can quantum computers predict the stock market?

Using pairs of quasi-particles, called non-abelian anyons, having their trajectories braided in time, topological quantum computer can effectively simulate the stock market behavior encoded in the braiding of stocks.

Can you predict stock prices with linear regression?

Using linear regression, a trader can identify key price points—entry price, stop-loss price, and exit prices. A stock's price and time period determine the system parameters for linear regression, making the method universally applicable.

Introduction

Using a neural network applied to the Deutsche Börse Public Dataset, we implemented an approach to predict future movements of stock prices using trends from the previous 10 minutes. Our motivation was to gain insights into this dataset and establish an architecture and approach from which we can iterate.

Data Preparation

We began by obtaining an extract of the data from the PDS AWS S3 bucket and examining its structure. The data comes with the following fields:

Exploratory Analysis

In general, before performing any form of machine learning, we need to thoroughly understand the data. Since we are not financial market experts, we have to build up a picture of the data’s behaviour and characteristics from the ground up.

Predicting Stock Price Movements Using A Neural Network

We designed a simple neural network approach using Keras & Tensorflow to predict if a stock will go up or down in value in the following minute, given information from the prior ten minutes. A notable difference from other approaches is that we pooled the data from all 50 stocks together and ran the network on a dataset without stock ids.

Summary

We have shown that we can use a neural network to predict future movements of stocks in the Deutsche Boerse Public Dataset and used this as the basis of a simplified trading strategy. The neural network model used here is intentionally simple, and there are a range of models and techniques that could yield better results.

Appendix

During the exploratory phase, we used Seasonal Decomposition to begin understanding the stock data as a time series. This method deconstructs a given time series into 3 components:

What is the driver of the valuation ratios?

Price is the driver of the valuation ratios, therefore, the findings do support the idea of a mean-reverting stock market. As prices climb, the valuation ratios get higher and, as a result, future predicted returns are lower.

Why is momentum important?

Momentum plays a part in the decision to invest and when more people invest, the market goes up, encouraging even more people to buy. It's a positive feedback loop. A 1993 study by Narasimhan Jegadeesh and Sheridan Titman, "Returns to Buying Winners and Selling Losers," suggests that individual stocks have momentum.

What is mean reversion?

The tendency of a variable, such as a stock price, to converge on an average value over time is called mean reversion. The phenomenon has been found in several economic indicators, which are useful to know, including exchange rates, gross domestic product (GDP) growth, interest rates, and unemployment.

Do high prices discourage investors?

Experienced investors, who have seen many market ups and downs, often take the view that the market will even out, over time. Historically, high market prices often discourage these investors from investing, while historically low prices may represent an opportunity.

Is there a momentum effect in the short term?

A good conclusion that can be drawn is that there may be some momentum effects in the short term and a weak mean-reversion effect in the long term.

What would an investor want to avoid?

The investor would want to avoid or downweight stocks with particularly high trading costs, notably stocks with low prices and small market capitalizations, and would be more interested in value- than equal-weighted portfolios. The investor also might avoid employing information from the past one-month return due to potential market-microstructure effects.

Is past return inversely related to future average returns?

Both short- (less than one month) and long-term (three-to-five year) past returns are inversely related to future average returns, while intermediate horizon past returns (three to 12 months) are positively related to future average returns. Classic papers include Jegadeesh (1990), DeBondt and Thaler (1985), and Jegadeesh and Titman (1993). 1

When day trading, do you profit from fundamental analysis?

When day trading, you don’t profit from fundamental analysis; you profit from buying and selling. You need to know what you will do when the market does what it is going to do. Unfortunately, the market doesn’t shout out when stock is going to surge in price. Table of Contents. How to Predict When a Stock Will Go Up.

Why are stocks under $10?

For the most part, they are under $10 because many are companies in their early development stages and not turning a profit. In an attempt to grow and raise more money, they issue more shares on the public market. Slowly but surely, they hope to become mega-cap stocks.

What does a 30% RSI mean?

A RSI value <30% means that the stock is oversold and is trading near the bottom of its high-low range. At this point, get ready for a reversal in the up direction. So if you’re wondering how to predict when a stock will go up, look at the RSI value.

What is VWAP in trading?

Next to volume, VWAP or the Volume Weighted Average Price is an important day trading technical indicator. I know of some traders who only use VWAP and volume to confirm their entry and exit points!

What does "float" mean in stock?

By definition, “float” means the number of shares available for trading. For example, as of October 2020, Apple had 17.09 billion shares in the market to buy and sell. Because of this large number, we consider Apple a “mega cap” stock.

Does volume precede price?

More importantly, volume precedes price. A surge in volume is mandatory to confirm a breakout. If there’s no volume, it is not a breakout; it could be just a false rally. Thus, if you’re looking at a significant price movement, it’s critical you also example the volume to see whether it tells the same story.

Is it hard to trade low float stocks?

But, I do need to warn you of something. As a new trader, trading low float stocks can be difficult but not impossible. Because they move quickly, it can be hard to manage your risk. Luckily, Bullish Bears will give you the strategies to manage risk, so you don’t blow up your account.

Why are stock movements short term?

Most methods of determining stock movement are short term. This is because shocks to the system cannot be determined very far in advance. There are so many political and economic variables that affect the market, long term predictions are normally insignificant. There are too many assumptions involved.

What is the most important variable in determining price changes?

Volume can become the most important variable in determining price changes. Generally speaking, if volume is increasing, then the price of the stock you are watching is increasing too. This trend will normally continue in the short term.

What is volume in stock market?

Use volume to predict stock movement. “Volume” is the number of trades in the market per day. Here, the basic rule is that changes in volume normally come before shifts in price.

Is stock price a science?

Predicting stock price movements is not, and will never be, an exact science. Many theories and methods exist for determining stock fluctuation, but none of these are a substitute for real market experience. The range of methods for determining stock price movement go from the simple and obvious to the highly technical. All have their devotees.
