Never mingle your speculative and investment operations in the same account nor in any part of your thinking.
Benjamin GrahamSpeculators often prosper through ignorance; it is a clichรฉ that in a roaring bull market knowledge is superfluous and experience is a handicap. But the typical experience of the speculator is one of temporary profit and ultimate loss
Benjamin GrahamThe most realistic distinction between the investor and the speculator is found in their attitude toward stock-market movements. The speculator's primary interest lies in anticipating and profiting from market fluctuations. The investor's primary interest lies in acquiring and holding suitable securities at suitable prices. Market movements are important to him in a practical sense, because they alternately create low price levels at which he would be wise to buy and high price levels at which he certainly should refrain from buying and probably would be wise to sell.
