In my last post I discussed an investment metric known as alpha. Alpha is a gauge of risk-adjusted returns provided by a portfolio manager. Alpha isn’t the only measure of a stock or portfolio’s risk profile. Another one is called beta. Beta measures a stock’s volatility in comparison to the overall market. A beta value of 1 is assigned to the overall market. So a stock that has a beta of one would be considered to move in lockstep with the overall market. If the market were to go up by 10%, the stock should also move by the same amount in the same direction.
A stock that moves less than the overall market would have a beta less than one. A beta greater than one indicates a stock that moves in the same direction as the overall market but in more extreme swings. Beta can be a good figure to use in rule-of-thumb investment decisions but it does have one serious drawback of which investors should be aware. Beta is calculated based on historical price movements relative to the market. Because of this method of calculation it doesn’t take into account any new information about the underlying fundamentals of the company. Due to this limitation, beta should never be used in a vacuum.
Remember, statistics like alpha and beta can provide guideposts to help you evaluate an investment manager or the risk of a particular stock but they shouldn’t be relied upon to replace the hard work of fundamental analysis. It is the key things going on with a company’s balance sheet and income statement that are the true underpinnings of the stock’s valuation. Keep this in mind when evaluating stocks or portfolios and you’ll be in good shape.
I’m not saying that statistics like alpha and beta should be ignored; they’re great tools. Just don’t let them be the only tools you use when making investment decisions.

Triglyceride level?
DefinitionThe triglyceride level is a laboratory test to measure the amount of triglycerides in your blood. Triglycerides are a type of fat.Your body makes some triglycerides. Triglycerides also come from the food you eat. When you eat, your body uses carbohydrate calories for immediate energy. Leftover calories are turned into triglycerides and stored in fat cells for later use. If you eat more calories than your body needs, your triglyceride level may be high.See also:Low density lipoprotein testHigh density lipoprotein testHigh blood cholesterol and triglyceridesTotal cholesterol testAlternative NamesTriacylglycerol testHow the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How to prepare for the testYou should not eat for 8 to 12 hours before the test.Alcohol and certain drugs may affect test results. Make sure your doctor knows what medicines you take, including over-the-counter drugs and supplements. Your doctor may tell you to temporarily stop taking certain medicines. Never stop taking any medicine without first talking to your doctor.Drugs that can increase triglyceride measurements include beta blockers, cholestyramine, colestipol, estrogens, protease inhibitors, retinoids, certain antipsychotics, and birth control pills.Drugs that can decrease triglyceride measurements include ascorbic acid, asparaginase, clofibrate, fenofibrate, fish oil, gemfibrozil, nicotinic acid, and statin medications.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThe most important use of this test is to help estimate your LDL cholesterol. This test is also done to help determine your risk of developing heart disease. A high triglyceride level may lead to atherosclerosis, which increases your risk of heart attack and stroke. A high triglyceride level may also cause inflammation of your pancreas.Persons with a high triglyceride level often have other conditions such as diabetes and obesity that also increase the chances of developing heart disease.The triglyceride level is usually included in a lipid panel or coronary risk profile.Normal ValuesNormal: Less than 150 mg/dLBorderline High: 150 - 199 mg/dLHigh: 200 - 499 mg/dLVery High: 500 mg/dL or aboveWhat abnormal results meanHigh triglyceride levels may be due to:CirrhosisDiet low in protein and high in carbohydratesFamilial hyperlipoproteinemia (rare)HypothyroidismNephrotic syndromePancreatitisPoorly controlled diabetesLow triglyceride levels may be due to:Low fat dietHyperthyroidismMalabsorptionsyndromeMalnutritionAdditional conditions under which the test may be performed:Chylomicronemia syndromeHyperlipidemia; acquiredFamilial combined hyperlipidemiaFamilial dysbetalipoproteinemiaFamilial hypertriglyceridemiaFamilial lipoprotein lipase deficiencyNoninsulin-dependent diabetes (NIDD)Stroke secondary to atherosclerosisWhat the risks areVeins and arteries vary in size from one patient to another, and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others. Other risks may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsPregnancy can interfere with test results.ReferencesExpert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults.

What are three types of beta decay?
The three types of beta decay are beta-minus decay (emission of an electron), beta-plus decay (emission of a positron), and electron capture (where a proton captures an electron and converts into a neutron).

How many protons will uranium have after releasing a beta particle?
It depends on whether the beta decay sequence is beta- or beta+. In beta-, the atom will gain a proton, changing into neptunium. In beta+, the atom will lose a proton, changing into protactinium.

What is a charge of beta?
A beta charge refers to the charge carried by a beta particle, which can be either a beta minus (electron) with a charge of -1 or a beta plus (positron) with a charge of +1. Beta decay is a type of radioactive decay process involving the emission of beta particles.
