​If your stock is in a loss, you have several options to consider. However, there is no definitive answer to what you should do, as it depends on various factors such as your investment objectives, time horizon, risk tolerance, and the fundamentals of the stock. Here are some possible options and scenarios:
 
•  Hold the stock: If you believe that the stock is undervalued and has strong growth potential in the long term, you may decide to hold the stock and wait for its price to recover. This option requires patience and confidence in your analysis and judgment. You should also monitor the stock's performance and news regularly and reassess your expectations and assumptions. However, you should also be aware of the opportunity cost of holding a losing stock, as you may miss out on other profitable investments.

​The answer to when you should start investing in the stock market depends on your personal and financial situation, but generally speaking, the sooner the better.

​A stock market correction is a decline of 10% to 30% in the value of a market index or an individual asset from a recent peak (30% or more). It is a temporary and unavoidable phenomenon for investors. A correction is different from a bear market, which is more severe and lasting.
 
Identifying that the stock market correction is over can be difficult, as there is no definitive sign or rule that indicates the end of a correction. However, some possible indicators of a correction being over are:

​A stock market bubble is a type of economic bubble that occurs when the prices of stocks or other assets far exceed their intrinsic or fundamental value. Bubbles are driven by investor sentiment and psychology, which generate a positive feedback loop of rising prices and additional buying. The bubble inflates until stock prices reach a level beyond economic or fundamental rationality, and/or when the new investment flows that would be necessary from investors and speculators to drive further price increases actually dries up. When no more investors can be found to invest at that price level, the bubble usually begins to collapse.

Identifying a stock market bubble can be challenging, as there is no definitive measure of what constitutes a fair value for an asset. However, some possible indicators of a bubble are:

Technical indicators are mathematical calculations based on a stock's price and/or volume that can help traders identify trends, patterns, and signals in the market. There are many types of technical indicators, but some of the best ones for researching a company stock for investment are:
 
•  Moving average (MA): This indicator shows the average price of a stock over a certain period of time. It helps smooth out the price fluctuations and shows the direction and strength of a trend. Traders can use different types of moving averages, such as simple, exponential, or weighted, and different time periods, such as 10-day, 50-day, or 200-day, depending on their trading style and objectives. Moving averages can also be used to generate buy and sell signals when they cross each other or when the price crosses them.

​There are many metrics that can help you research a company stock for investment, but some of the most common and useful ones are:
 
• Price-to-earnings ratio (P/E ratio): This metric compares a company's current price to its per-share earnings. It shows how much the market is willing to pay for a stock based on its past or future earnings. A low P/E ratio may indicate that a stock is undervalued or has strong growth prospects, while a high P/E ratio may indicate that a stock is overvalued or has weak growth prospects
