StarPower Semiconductor has the GF Score of 93, which implies that the company
might have
Highest outperformance potential.
The GF Score is a stock performance ranking system developed by GuruFocus using five aspects of valuation, which has been found to be closely correlated to the long-term performances of stocks by backtesting from 2006 to 2021. The stocks with a higher GF Score generally generate higher returns than those with lower GF Scores. Therefore, when picking stocks, investors should invest in companies with high GF Scores. The GF Score ranges from 0 to 100, with 100 as the highest rank.
GF Score takes following five key aspects into consideration:
Each one of these components is ranked and the ranks also have positive correlation with the long term performances of stocks. The GF score is calculated using the five key aspects of analysis. Through backtesting, we know that each of these key aspects has a different impact on the stock price performance. Thus, they are weighted differently when calculating the total score. The Profitability Rank and the Growth Rank are weighted fully, while other parameters have less weight.
Based on research and backtesting result, GuruFocus believes StarPower Semiconductor
might have
Highest outperformance potential.
