  • A – Annual Earnings Growth: Look for companies with a track record of consistent annual earnings growth of at least 25% over the past three years.
  • N – New Product, Service, Management, Highs or Lows: Look for companies that have introduced a new product or service, have a new management team, or are reaching new highs in the stock price.
  • S – Supply and Demand: Look for stocks with a low supply and high demand. This can be indicated by high trading volume and institutional buying.
  • L – Leader or Laggard: Look for stocks that are leaders in their industry or sector or have shown recent strength compared to their peers.
