"Never give anyone the advice to buy or sell shares, because the most benevolent price of advice can turn out badly"

This quote by Francois de La Rochefoucauld is a caution against providing guidance to others about purchasing or selling shares. He is cautioning that even the most well-intentioned guidance can have unintended effects. He is recommending that it is best to leave choices about buying and offering shares to the individual, as they are the ones who will need to live with the results of their decisions. He is likewise suggesting that the stock market is unforeseeable which nobody can predict the future. By giving recommendations, one is taking a threat that the suggestions might not turn out as expected. Therefore, it is best to leave choices about purchasing and offering shares to the individual. This quote acts as a suggestion that even the most kindhearted recommendations can have unintentional effects and that it is best to leave decisions about investing to the person.
