The mathematical expectation of the speculator is zero. — © Louis Bachelier
The mathematical expectation of the speculator is zero.
The great appeal of the doctrine that the mind is a blank slate is the simple mathematical fact that zero equals zero.
The only number that would ever be enough is 0. Zero pounds, zero life, size zero, double-zero, zero point. Zero in tennis is love. I finally get it.
We are convinced that the intelligent investor can derive satisfactory results from pricing of either type (market timing or fundamental analysis via price). We are equally sure that if he places his emphasis on timing, in the sense of forecasting, he will end up as a speculator and with a speculator's financial results." And "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.
If [Donald Trump] is paid zero [taxes], that means zero for troops, zero for vets, zero for schools or health.
A zero itself is nothing, but without a zero you cannot count anything; therefore, a zero is something, yet zero.
If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.
Just remember, without discipline, a clear strategy, and a concise plan, the speculator will fall into all the emotional pitfalls of the market - jump from one stock to another, hold a losing position too long, and cut out of a winner too soon, for no reason other than fear of losing profit. Greed, Fear, Impatience, Ignorance, and Hope will all fight for mental dominance over the speculator. Then, after a few failures and catastrophes the speculator may become demoralised, depressed, despondent, and abandon the market and the chance to make a fortune from what the market has to offer.
It follows that the word probability, in its mathematical acceptance, has reference to the state of our knowledge of the circumstances under which an event may happen or fail. With the degree of information we possess concerning the circumstances of an event, the reason we have to think that it will occur, or, to use a single term, our expectation of it will vary. Probability is the expectation founded upon partial knowledge.
People like Donald Trump, who paid zero in taxes, zero for our vets, zero for our military, zero for health and education, that is wrong.
The federal investment in finding cures for cancer - $3 billion annually [as of 1999] - is less than ... zero ... point ... zero ... zero ... zero ... four ... percent of our gross domestic product, or about one-seventh of what Americans spend on beauty products.
Neutrinos ... win the minimalist contest: zero charge, zero radius, and very possibly zero mass.
Carbon zero simply means that the emissions you are releasing either are zero or balance out to zero.
It is only fair to admit, however, that my batting average in the crystal ball league is point, zero, zero, zero.
What's at the end of a million dollars? Zero, zero, zero... nothing. A circle with a hole in it.
Men cannot be treated as units in operations of political arithmetic because they behave like the symbols for zero and the infinite , which dislocate all mathematical operations.
The reality is that zero defects in products plus zero pollution plus zero risk on the job is equivalent to maximum growth of government plus zero economic growth plus runaway inflation.
