The Rule of 20 helps assess if the stock market is fairly priced by adding the S&P 500's P/E ratio to the annual inflation rate. Historically, a total of 20 indicates a fair market value.
If you have a balanced hand and 12 to 14 points bid 1NT. A balanced hand has suit distributions 4333, 4432 or 5332, where the five-card suit is diamonds or hearts. If you have a balanced hand and 20 to 22 points bid 2NT. Here, a balanced hand is 4333, 4432, 5332 (where the five-card suit can be any suit) or 5422.
In other words, the Rule of 20 suggests that markets may be fairly valued when the sum of the P/E ratio and the inflation rate equals 20. The stock market is deemed to be undervalued when the sum is below 20 and overvalued when the sum is above 20.
The 70% rule for retirement savings says your estimated retirement spending will be 70% of your pre-retirement, post-tax income. Multiplying your post-tax income by 70% can give you an idea of how much you may spend once you retire.
In other words, we are at the Golden Rule when the steady state capital-labor ratio, k*, is such that the marginal product of capital is equal to the natural growth rate, ¦ k = n.
You can open the bidding with slightly fewer than 12 points when you have a shapely hand. Use the Rule of 20 – which states that you can open the bidding when your high-card point-count added to the number of cards in your two longest suits gets to 20.
In most natural bridge bidding systems, the opening bid of 2♣ is used exclusively for hands too strong for an opening bid at the one-level. Typically, the bid is reserved for hands that are almost strong enough to bid to the game level on their own power, or even stronger.
The Rule of 20 is not relevant in Third or Fourth Seat. Also, Mr. Marty Bergen strongly suggests that most hands worth opening in first or second seat have at least 2 Quick Tricks.
The 50-30-20 rule involves splitting your after-tax income into three categories of spending: 50% goes to needs, 30% goes to wants, and 20% goes to savings.
An offer by a body to issue securities results in a breach of the 20 investors ceiling or 20/12 rule if it results in the number of people to whom securities of the body have been issued or sold exceeding 20 in any 12-month period (sections 708(3) and 708(4) and sections 1012E(6) and 1012E(7), CA 2001).
In this case, P = $100, r = 15% or 0.15, n = 1 (since the interest is compounded annually), and t = 20 years. Plugging these values into the formula gives us: A = $100(1 + 0.15/1)^(1*20) = $100(1.15)^20. After calculating this, the total amount A comes out to be approximately $16,366.53.
Basic Bridge Bidding Strategies
Make a bid in hearts or spades if you have 12-21 HCP and at least 5 cards in the suit. Bid 1-Club or 1-Diamond if you have 3 cards in the suit and 12-21 HCP. Choose no suit if you have an even number of cards in each suit and 15-17 HCP. Pass the bid if you have below 11 HCP in your hand.
The rule combines two key factors: the Price-to-Earnings (P/E) ratio and the expected earnings growth rate of a stock. In essence, the fair value P/E ratio should equal the expected earnings growth rate plus 20.
After a 1NT opening, a bid of 2♦ or 2♥ is a transfer bid. We bid the suit ranking immediately below the suit we hold. Opener MUST bid the next suit up at the lowest level (with one exception see Page 4 'Super Acceptance'). Here we bid 2♥.
This hand is known as a "weak freak". The characteristics of a "weak freak" are: five or more cards in support of opener's major, few high cards (usually no more than 7 HCP), and other distribution such as a singleton or void.
The most effective bridge design depends on the specific situation. However, truss bridges are often considered highly efficient for their strength-to-weight ratio. Truss bridges use a series of connected triangles to distribute forces evenly, making them ideal for long spans and heavy loads.
Rule of seven
The rule assumes play in a 3NT contract and is as follows: Subtract from seven the total number of cards that declarer and dummy hold in the defenders' suit and duck their lead of the suit that many times.
Counting Your Losers
Void : No losers Singleton suit : Count one loser, unless it's an ace singleton (0). Doubleton : Count two losers except for A-K (0), A-x (1) or K-x (1). Count Q-x as 2 losers. 3-card or longer suit : Count three losers but deduct one for the ace, king or queen.
With 22+ high card points, opener will bid notrump (with a balanced hand) or a suit (with a hand unsuitable for notrump). With balanced hands, a bid of 2NT shows 22 to 24 points, while a bid of 3NT shows 25 to 27 points.
In the early 1960s, he derived the “Golden Rule” of capital formation. The rule is that if one's goal is to attain the maximum consumption per capita that is sustainable in the long run, annual saving as a percent of national income should equal capital's income as a percent of national income.
The Golden Rule tells us to “do unto others as we would have done unto ourselves,” which is one way to look at behaving in the world. This rule, however, instructs us to put our preferences before the Other's.
The name “golden rule” reflects the maxim of Jesus, “do unto others as you would have them do unto you”: the current generation saves at the high golden-rule rate, which benefits the future generation.
