Can I evaluate the performance of a company using just OHLC data?
No. The information you are describing is technical data about a stock's market price and trading volume, only. There is nothing implied in that data about a company's financial fundamentals (earnings/profitability, outstanding shares, market capitalization, dividends, balance sheet assets and liabilities, etc.) All you can infer is positive or negative momentum in the trading of the stock. If you want to understand if a company is performing well, then you need fundamental data about the company such as you would get from a company's annual and quarterly reports.
