Look at the balance sheet, look at the profits, etc. Go to the company first and look at their statements. To look at profits, you need to look at their sales revenue.

For example, what is the percentage of profit. The size of the gross profit will tell you how well a company is buying.

If the ratio of gross profit to sales is large, it means that it is cheap to buy. From the dividend, you can tell whether the company is focused on investment,

or on short-term profit. The ratio of working capital to current liabilities shows the company's ability to repay others.

If it is too low, it can show that the management of the company is not efficient, if it is too high, it shows that the company is not good at investment.

Otherwise, you can look at the company's managers to understand their background and assess their ability and suitability for the company. Or you can look at the past performance and then you have to see how the company's loans are. If it is too much, it is risky, or the bottom line is not good enough. Dividing the net profit by the sales will tell you how well the company manages its consumption in other areas, such as utilities, office supplies, etc. If the result is high, it means the company is saving money. If the result is high, it means that the company is economical and well-managed, if it is low, it means that the company is not very efficient. Finally, the company's results for each year are compared,

If it is a significant increase, it can show that the company is moving in the right direction.
