50. selling apple stock limit order
Your order may or may not be executed.  The price of stock can open anywhere.  Often yesterday's close is a good indication of today's open, but with a big event overnight, the open may be somewhere quite different.  You'll have to wait and see like the rest of us.  Also, even if it doesn't execute at the open, the price could vary during the day and it might execute later.

51. How do I get rid of worthless penny stocks if there is no volume (so market/limit orders don't work) and my broker won't buy them from me?
Merrill charges $500 flat fee to (I assume purchase) my untraded or worthless security. In my case, it's an OTC stock whose management used for a microcap scam, which resulted in a class action lawsuit, etc. but the company is still listed on OTC and I'm stuck with 1000s of shares. (No idea about the court decision)

52. Why is day trading considered riskier than long-term trading?
In day trading, you're trying to predict the immediate fluctuations of an essentially random system.  In long-term investing, you're trying to assess the strength of a company over a period of time. You also have frequent opportunities to assess your position and either add to it or get out.

53. Why would you elect to apply a refund to next year's tax bill?
The refund may offset your liability for the next year, especially if you are a Schedule "C" filer.  By having your refund applied to the coming year's taxes you are building a 'protection' against a potentially high liability if you were planning to sell a building that was a commercial building and would have Capital Gains. Or you sold stock at a profit that would also put you in the Capital Gain area.  You won a large sum in a lottery, the refund could cushion a bit of the tax. In short, if you think you will have a tax liability in the current year then on the tax return you are filing for the year that just past, it may be to your benefit to apply the refund.  If you owe money  from a prior year, the refund will not be sent to you so you will not be able to roll it forward.    One specific example is you did qualify in the prior year for the ACA.  If in the year you are currently in- before you file your taxes-- you realize that you will have to pay at the end of the current year, then assigning your refund will pay part or all of the liability. Keep in mind that the 'tax' imposed due to ACA is only collected from your refunds.  If you keep having a liability to pay  or have no refunds due to you, the liability is not collected from you.

54. Can individuals day-trade stocks using High-Frequency Trading (HFT)?
I just finished a high frequency trading project. Individuals can do it, but you need a lot of capital. You can get a managed server in Times Square for $1500/month, giving you access to 90% of the US exchanges that matter, their data farms are within 3 milliseconds of distance (latency). You can also get more servers in the same building as the exchanges, if you know where to look ;) thats all I can divulge good luck

55. Does the profit of a company directly affect its stock or indirectly by causing people to buy or sell?
people implicity agree to sell stocks when a company does bad But, remember, when you sell the stock of a company that, in your estimation, 'did bad', someone else had to buy; otherwise, there is no sale. The someone else who bought your shares evidently disagrees with your assessment. Did you sell because the company didn't earn a profit at all? Did it not earn a profit because it's in a dead-end business that is slowly but inevitably declining to zero? Something like Sears Holdings? Or did it not make a profit because it is in an emerging market that will possibly someday become hugely profitable? Something like Tesla, Inc.? Did you sell because the company made a profit, but it was lower than expected? Did they make a lower-than-expected profit because of lower sales? Why were the sales lower? Is the industry declining? Was the snow too heavy to send the construction crews out? Did the company make a big investment to build a new plant that will, in a few years, yield even higher sales and profits? What are the profits year-over-year? Increasing? Declining? Usually, investors are willing to pay a premium, that is more than expected, for a stock in a company with robust growth.  As you can see, the mere fact that a company reported a profit is only one of many factors that determine the price of the shares in the market.

56. Does a stock holder profit from a reverse-stock split?
If I held stock in these companies yesterday, would I have profited by these gains? No.  For DZSI, your 5 shares at $1.10 would now be 1 share at $5.50, so you would have the same total amount.  For SGY, they closed at $6.95, and opened at $32.80, so your five shares at $6.95 would now be one share at $32.80, so you would have actually lost money (not purely because of the split, but because the "new" shares are trading lower then the expected 1:5 split price).  A split in general does not affect market cap (how much your total shares are worth) but there may be residual effects that cause the market value to fluctuate after a split that affect the price.

57. How would bonds fare if interest rates rose?
1. Interest rates What you should know is that the longer the "term" of a bond fund, the more it will be affected by interest rates. So a short-term bond fund will not be subject to large gains or losses due to rate changes, an intermediate-term bond fund will be subject to moderate gains or losses, and a long-term bond fund will be subject to the largest gains or losses. When a book or financial planner says to buy "bonds" with no other qualification, they almost always mean investment-grade intermediate-term bond funds (or for individual bonds, the equivalent would be a bond ladder averaging an intermediate term). If you want technical details, look at the "average duration" or "average maturity" of the bond fund; as a rough guide, if the duration is 10, then a 1% change in interest rates would be a 10% gain or loss on the fund. Another thing you can do is look at long-term (10 years or ideally longer) performance history on some short, intermediate, and long term bond index funds, and you can see how the long term funds bounced around more. Non-investment-grade bonds (aka junk bonds or high yield bonds) are more affected by factors other than interest rates, including some of the same factors (economic booms or recessions) that affect stocks. As a result, they aren't as good for diversifying a portfolio that otherwise consists of stocks. (Having stocks, investment grade bonds, and also a little bit in high-yield bonds can add diversification, though. Just don't replace your bond allocation with high-yield bonds.) A variety of "complicated" bonds exist (convertible bonds are an example) and these are tough to analyze. There are also "floating rate" bonds (bank loan funds), these have minimal interest rate sensitivity because the rate goes up to offset rate rises. These funds still have credit risks, in the credit crisis some of them lost a lot of money. 2. Diversification The purpose of diversification is risk control. Your non-bond funds will outperform in many years, but in other years (say the -37% S&P 500 drop in 2008) they may not. You will not know in advance which year you'll get. You get risk control in at least a few ways. There's also an academic Modern Portfolio Theory explanation for why you should diversify among risky assets (aka stocks), something like: for a given desired risk/return ratio, it's better to leverage up a diverse portfolio than to use a non-diverse portfolio, because risk that can be eliminated through diversification is not compensated by increased returns. The theory also goes that you should choose your diversification between risk assets and the risk-free asset according to your risk tolerance (i.e. select the highest return with tolerable risk). See http://en.wikipedia.org/wiki/Modern_portfolio_theory for excruciating detail. The translation of the MPT stuff to practical steps is typically, put as much in stock index funds as you can tolerate over your time horizon, and put the rest in (intermediate-term investment-grade) bond index funds. That's probably what your planner is asking you to do. My personal view, which is not the standard view, is that you should take as much risk as you need to take, not as much as you think you can tolerate: http://blog.ometer.com/2010/11/10/take-risks-in-life-for-savings-choose-a-balanced-fund/ But almost everyone else will say to do the 80/20 if you have decades to retirement and feel you can tolerate the risk, so my view that 60/40 is the max desirable allocation to stocks is not mainstream. Your planner's 80/20 advice is the standard advice. Before doing 100% stocks I'd give you at least a couple cautions: See also:

58. What implications does having the highest household debt to disposable income ratio have on Australia?
It is basically the same situation what US was when the crash happened. People took on debt without the means to pay, even with awful credit records. But the problem isn't the debt people take on themselves, but with the limited disposable income they have how efficiently can their debts be serviced. And how do banks who lend out money can recover their money. When banks lend money to all and sundry, they have to take care of defaults and that is when financial wizardry comes into play. In US people have the option to default on their debt and refinance it, so banks assumed default and tried to hedge their risks. If this is an option in Australia, be ready for a crash else not to worry about much. If banks continue lending expect higher inflation rates, higher interest rates and maybe a downgrade of bonds issued by the Australian government. Higher import costs and a boom in exports because of devalued Australian dollar.

59. why do I need an emergency fund if I already have investments?
Given that the 6 answers all advocate similar information, let me offer you the alternate scenario - You earn $60K and have an employer offering a 50% match on all deposits. All deposits. (Note, I recently read a Q&A here describing such an offer. If I see it again, I'll link).  Let the thought of the above settle in. You think about the fact that $42K isn't a bad salary, and decide to deposit 30%, to gain the full match on your $18K deposit. Now, you budget to live your life, pay your bills, etc, but it's tight. When you accumulate $2000, and a strong want comes up (a toy, a trip, anything, no judgement) you have a tough decision. You think to yourself, "after the match, I am literally saving 45% of my income. I'm on a pace to have the ability to retire in 20 years. Why do I need to save even more?"  Your budget has enough discretionary spending that if you have a $2000 'emergency', you charge it and pay it off over the next 6-8 months. Much larger, and you know that your super-funded 401(k) has the ability to tap a loan. Your choice to turn away from the common wisdom has the recommended $20K (about 6 months of your spending) sitting in your 401(k), pretax deposited as $26K, and matched to nearly $40K, growing long term.  Note: This is a devil's advocate answer. Had I been the first to answer, it would reflect the above.  In my own experience, when I got married, we built up the proper emergency fund. As interest rates fell, we looked at our mortgage balance, and agreed that paying down the loan would enable us to refinance and save enough in mortgage interest that the net effect was as if we were getting 8% on the money. At the same time as we got that new mortgage, the bank offered a HELOC, which I never needed to use. Did we somehow create high risk? Perhaps. Given that my wife and I were both still working, and had similar incomes, it seemed reasonable.

60. Is it a good practice to keep salary account and savings account separate?
I pretty much only use my checking. What's the downside? Checking accounts don't pay as much interest as savings account. Oh, but wait, interest rates have been zero for nearly 10 years. So there is very little benefit to keeping money in my savings account. In fact, I had two savings accounts, and Well Fargo closed one of them because I hadn't used it in years. Downsides of savings accounts: You are limited to 5 transfers per month into or out of them. No such limit with checking. Upsides of savings accounts: Well, maybe you will be less likely to spend the money. Why don't you just have your pay go into your checking and then just transfer "extra money" out of it, rather than the reverse? If you want to put money "away" so that you save it, assuming you're in the U.S.A., open a traditional IRA. Max deposit of $5500/year, and it reduces your taxable income. It's not a bad idea to have a separate account that you don't touch except for in an emergency. But, for me, the direction of flow is from work, to checking, to savings.

61. Why does it seem unnecessary to fully save for irregular periodic expenses?
It totally depends on when your expenses hit and whether you might have a larger stock than necessary. If you run your projections against the monthly save and the intervals of when you'll need the money, you might be able to extract some stock from the account.  I recommend making this a bit simpler. I operate this with an "annuals" account which is a complete aggregate of expenses that I know I have several times per year (or once every two years), but are not monthly or part of a weekly non-fixed expense budget cap. Instead of tracking each expense individually and saving for it, create a spreadsheet that lists out all of these expenses, sum them, and then divide by 12. When I first opened this account, I added a one-time deposit to "catchup" to make sure I would never need to pull money from another source for these expenses. As new expenses come into existence that I should plan for annually, I simply add them to this list and adjust the monthly auto-deposit to the account. This also adjusts my single number weekly budget.  To make it easy, whenever I see an expense on my annuals list on my amex or debit, I simply initiate a withdrawal from the annuals savings and it will balance out my weekly or monthly budget expenses.  The goal of my annuals account is to simply avoid anti-windfalls that are known quantities (insurance, annual eye exam, sprinkler flush, amazon prime, etc) that would throw a wrench in weekly/monthly budget and expense planning. The more variables you can remove from your weekly/monthly, the more regular it becomes and the more likely you will be able to stick to a budget.

62. Why do some stocks have a higher margin requirement?
It is a question of how volatile the stock is perceived to be, its beta correlation to the S&P500 or other index. Margin requirements are derived from the Federal Reserve, Self Regulatory Organizations, the exchange itself, the broker you use, and which margining system you are using. So that makes this a loaded question. There are at least three margin systems, before you have your own risk officer in a glass room that doesn't care how leveraged up you get. Brokers primarily don't want to lose money.

63. Do I have to pay taxes on income from my website or profits?
Being a tax professional, my understanding is that the threshold limit is a single limit for all your source(s) of income. Now many people who already draw salary which is liable to tax, develop application for mobile and generate some income. Such income is liable to tax, if along with other income they exceed the threshold limit.  Income will have surely related expenses. And the expenses which are related to earning of the income are allowed to be deducted.

64. Is it better to buy US stocks on US stock exchanges as a European?
Liquidity on dual listed equities is rarely the same on both exchanges. More liquidity means you would typically get a better price assuming you execute the trades using the same order types. It's recommended to trade where the liquidity is greater unless your trading method benefits somehow from it being lower. It's important to remember that some ADRs (some European companies listed in US) have ADR fees which vary. USD/EUR transaction fees are low when using a decent broker but you're obviously participating in the currency risk.

65. Why do governments borrow money instead of printing it?
“Why do governments borrow money instead of printing it? (When printing money, one doesn't need to pay interest).”  Good question.  Numerous leading economists, including a couple of economics Nobel Laureates have asked the same question and concluded that borrowing can be dispensed with. First, Milton Freidman set out a monetary system in a paper in the American Economic Review which involved no government borrowing, and govt just printed money (in a responsible fashion of course) as and when needed.  See: http://www.jstor.org/pss/1810624 A second Nobel Laureate with similar views was William Vickrey. A third economist with similar views (of Keynes’ era) was Abba Lerner. Keynes said of Lerner, “Lerner's argument is impeccable, but heaven help anyone who tries to put it across to the plain man at this stage of the evolution of our ideas”.

66. how derivatives transfer risk from one entity to another
The important thing to realize is, what would you do, if you didn't have the call? If you didn't have call options, but you wanted to have a position in that particular stock, you would have to actually purchase it. But, having purchased the shares, you are at risk to lose up to the entire value of them-- if the company folded or something like that.  A call option reduces the potential loss, since you are at worst only out the cost of the call, and you also lose a little on the upside, since you had to pay for the call, which will certainly have some premium over buying the underlying share directly. Risk can be defined as reducing the variability of outcomes, so since calls/shorts etc. reduce potential losses and also slightly reduce potential gains, they pretty much by definition reduce risk. It's also worth noting, that when you buy a call, the seller could also be seen as hedging the risk of price decreases while also guaranteeing that they have a buyer at a certain price. So, they may be more concerned about having cash flow at the right time, while at the same time reducing the cost of the share losing in value than they are losing the potential upside if you do exercise the option. Shorts work in the same way but opposite direction to calls, and forwards and futures contracts are more about cash flow management: making sure you have the right amount of money in the right currency at the right time regardless of changes in the costs of raw materials or currencies. While either party may lose on the transaction due to price fluctuations, both parties stand to gain by being able to know exactly what they will get, and exactly what they will have to pay for it, so that certainty is worth something, and certainly better for some firms than leaving positions exposed. Of course you can use them for speculative purposes, and a good number of firms/people do but that's not really why they were invented.
