Much Ado about Nothing is a comedy by William Shakespeare, thought to have been written in 1598-99. Having won a military victory, Don Pedro and his soldiers travel to Messina, where they are invited by the governor, Leonato, to stay for a month. Benedick, one of Don Pedro's companions, is reunited with former lover Beatrice, though the two are unable to admit that they are still in love with each other.
Meanwhile, Claudio proposes to Leonato's daughter, Hero, and the two plan to get married. However, Don John, Don Pedro's half-brother, is unhappy about the turn of events and plans to sabotage the wedding.
The key moment
In an attempt to sow discord, Don John claims to Claudio that Hero has been unfaithful to him. Don John even arranges for Claudio to observe what seems to be his fiance cheating on him, though in reality the person he sees is Margaret, Hero's attendant, having an assignation with Don John's servant, Borachio.

As a result, Claudio humiliates Hero by refusing to go through with the wedding, denouncing her in front of everyone. This enrages Don Pedro, and also infuriates Beatrice, who demands that Benedick kill Claudio.
Lessons for investors
Blindly following tips and rumours can lead to disaster. One of financier Bernard Baruch's top ten investment rules was "beware of barbers, beauticians and waiters or anyone bringing gifts of inside information or tips".
Such tips show "that there is no more dangerous illusion than the belief that one can get something for nothing". Even if the source is reliable, its easy to misunderstand them, like the relative who bought shares in a company after overhearing Baruch talking about it on the phone, only to overlook that he was really shorting the stock.
Other financial wisdom
It's illegal for people to divulge (or act) on inside information, so even if you do make money, you could end up in jail. Usually, the people giving the tip either don't have any genuine inside information, are advancing their own agendas (just like Don John in the play) or both. It's common for scammers pushing dodgy stocks to claim to have inside information, to ensure that victims avoid the authorities because they don't want to get into trouble themselves.
