In his 1934 book Security Analysis, Benjamin Graham laid out the definition for investing versus speculating.

I answered it in the comments, but I figured I should post about it as well.

An investment operation is one which, upon thorough analysis, promises safety of principal and a satisfactory return. Operations not meeting these requirements are speculative.

When speaking of “investment” versus “speculation”, Ben Graham was talking about an investment operation — the entire portfolio strategy, regardless of any particular investment therein. And look closely at Buffett’s quote. He doesn’t say, “You’re right because the price will go up and you’ll make money on every investment.” Instead, Buffett admits that some investments will go bad.
Good poker players know that it is crucial to make the right decision, regardless of how the cards fall or what the outcome would have been.
