That's Not To Say There's No Such

There's No Use Diversifying Into Unknown Companies Just For The Sake Of Diversity. A Foolish Diversity Is The Hobgoblin Of Small Investors. That Said, It Isn't Safe To Own Just One Stock, Because In Spite Of Your Best Efforts, The One You Choose Might Be The Victim Of Unforeseen Circumstances. In Small Portfolios, I'd Be Comfortable Owning Between Three And Ten Stocks.

Everyone Has The Brainpower To Make Money In Stocks. Not Everyone Has The Stomach. If You Are Susceptible To Selling Everything In A Panic, You Ought To Avoid Stocks And Mutual Funds Altogether.

You Shouldn't Just Pick A Stock - You Should Do Your Homework.

When You Sell In Desperation, You Always Sell Cheap.

That's Not To Say There's No Such Thing As An Overvalued Market, But There's No Point Worrying About It.
