The SOXX-ETF mirrors the SOX Index. Be careful when you find a strong stock if the particular issue you are interested in is in a weak or declining index.
If the selling in the index is powerful enough your gem of a stock will probably go lower, too, because the "manager" may have to sell your "gem" to raise funds.
This is one of the reasons even great stocks decline. BUT, study your STRUCTURE, and enter at KEY support levels. After all, it's your money. Spend it wisely.
Look, the markets are a tough neighborhood. To quote the late, great Rodney Dangerfield: “I came from a real tough neighborhood. Once a guy pulled a knife on me. I knew he wasn't a professional, the knife had butter on it.”
I hope all of your trades go well. Don.
