you ought to treat the initial information (whatever brought this company to your attention) as if it were an anonymous and intriguing tip, mysteriously shoved into your mailbox. This will keep you from buying a stock just because you’ve seen something you like, or worse, because of the reputation of the tipper, as in: “Uncle Harry’s buying it, and he’s rich, so he must know what he’s talking about.” Or: “Uncle Harry’s buying it, and so am I, because his last stock tip doubled.”
