Successful investing requires combining technical and fundamental data rather than relying on emotion or market hype. When assessing a stock, you should focus on three critical indicators:

​Price-to-Earnings (P/E) Ratio: A fundamental metric comparing a stock's price to its earnings. High ratios suggest strong growth expectations or potential overvaluation, whereas low ratios often signal an undervalued opportunity.

​Relative Strength Index (RSI): A technical momentum tool rated on a 0–100 scale. Readings above 70 flag overbought conditions ripe for a drop, while levels below 30 point to oversold assets likely to rebound.

​Trading Volume: The indicator of price conviction. A breakout paired with high volume validates strong market support, while price spikes on low volume typically signal weak momentum or false traps.
