There's more...

Once we get past these fields, most of the other fields in our dataset are numeric. Let's define some of the most important ones:

Price: This indicates the ongoing dollar value to purchase one share of a company's stock.
Volume: This indicates the most recent number of shares of the stock transacted in a day.
Shares Outstanding: This is the total number of stock shares the company has issued.
P/E: The Price to Earnings ratio is the price of the company's stock divided by the company's earnings per share outstanding.
PEG: The P/E Growth ratio is the company's P/E ratio divided by its annual growth rate, and it gives you a sense of the valuation of the company's earnings relative to its growth.
EPS growth next year: This is the expected rate at which the company's earnings per share will grow in the next year.
Total Debt/Equity: The total debt to equity is used as a measure of financial health calculated by dividing the dollar value of the company's total debt with the equity in the company. This gives you a sense of how the company has been financing its growth and operations. Debt is more risky than equity, so a high ratio will be cause for concern.
Beta: This is a measure of the stock's volatility (swings in its price) relative to the overall stock market. A beta of 1 means the stock is as volatile as the market. A beta more than 1 means it's more volatile, while a beta less than 1 means it's less volatile.
RSI: The Relative Strength Index is a metric based on stock price activity, which uses the number of days a stock has closed higher than its opening price and the number of days a stock has closed lower than its opening price within the last two weeks to determine a score between 0 and 100. A higher index value indicates that the stock might be overvalued, and therefore, the price might drop soon; a lower value indicates that the stock might be undervalued, so the price might rise soon.
