317. What's the best way to make money from a market correction?
The best way to make money during a market correction is to be a financial services company handling transactions for people who think they can beat the market, and charging a percentage commission on each transaction, while keeping your own money somewhere nice and safe, stable and low-fee.

318. Should I change 401k investment options to prepare for rising interest rates?
I see that you're invested in a couple bond funds. You do not want to be invested in bonds when the Fed raises rates. When rates climb, the value of bond investments decline, and vice-versa. So that means you should sell bonds before a rate hike, and buy them before a rate drop.

319. Buying a small amount (e.g. $50) of stock via eToro “Social Trading Network” using a “CFD”?
As many people here have pointed out, a CFD is a contract for difference. When you invest in stock at eToro, you buy a CFD reflecting a bid on the price movement of the underlying stock, however, you do not actually own the stock or hold any rights shareholders have. The counterparty to the CFD is eToro. When you close your position, eToro shall pay you the amount representing the difference between your buy and sell price for each stock.  I suggest you read the following article about CFDs, it explains everything clearly and thoroughly: http://www.investopedia.com/articles/stocks/09/trade-a-cfd.asp#axzz2G9ZsmX3A As some of the responders have pointed out, and as is mentioned in the article, a broker can potentially misquote the prices of underlying assets in order to manipulate CFDs to their advantage. However, eToro is a highly reputable broker, with over 2 million active accounts, and we guarantee accurate stock quotes. Furthermore, eToro is regulated in Europe (Germany, UK, France, etc.) by institutions that exact strict regulations on the CFD trading sector, and we are obligated to comply with these regulations, which include accurate price quoting.  And of course, CFD trading at eToro has tremendous benefits. Unlike a direct stock investment, eToro allows you to invest as much or as little as you like in your favorite stocks, even if the amount is less than the relevant stock price (i.e. fraction stocks). For example:  if you invest $10 in Microsoft, and on the day of execution eToro’s average aggregated price was $30 after a spread of 0.1%, you will then have a CFD representing 0.33 stocks of Microsoft in your eToro account. In addition, with eToro you can invest in stock in the context of a social trading network, meaning that you can utilize the stock trading expertise of other trader to your advantage by following them, learning their strategies, and even copying their stock investments automatically. To put it briefly, you won’t be facing the stock market alone!  Before you make a decision, I suggest that you try stock trading with an eToro demo account. A free demo account grants you access to all our instruments at real market rates, as well as access to our social network where you can view and participate in trader discussions about trading stocks with eToro, all without risking your hard earned money. Bottom line – it’s free, there are no strings attached, and you can get a much firmer idea of what trading stocks with eToro is like. If you have any further questions, please don’t hesitate to contact us through our site: www.etoro.com.

320. How can I work out how much a side-job contracting will be taxed for?
Being self-employed, your "profit" is calculated as all the bills you send out, minus all business-related cost that you have (you will need a receipt for everything, and there are different rules for things that last for long time, long tools, machinery).  You can file your taxes yourself - the HRS website will tell you how to, and you can do it online. It's close to the same as your normal online tax return. Only thing is that you must keep receipts for all the cost that you claim.  Your tax: Assuming your gross salary is £25,000 and your profits are about £10,000, you will be paying 8% for national insurance, and 20% income tax. If you go above £43,000 or thereabouts, you pay 40% income tax on any income above that threshold, instead of 20%, but your national insurance payments stop.

321. Possible to use balance transfers to avoid interest with major credit cards?
Sure of course you can do balance transfers like this but you are way late to the party and it has gotten to be pretty challenging finding new cards to transfer balances to. Before the current financial crisis in the US you could get enormous amounts of credit (2-5 times a person's annual income) and transfer balances to your bank account to collect interest . There were a bunch of ways to the transfer everything from direct deposit to your bank account to a balance transfer check payable to yourself to overpaying another credit card and requesting a refund. Over paying another account sets off a lot of red flags now days but other methods still work. The financial atmosphere has changed a lot and there are very few available cards with no balance transfer fees or capped fees and the interest rates are a lot lower now so it really isn't worth doing.

322. How to correct a tax return filed electronically and already approved?
Simply file an amended return to correct the mistake. This happens all the time and is a standard procedure that every legitimate tax pro can handle. You can work it out with the tax pro about whose mistake it was and who should pay for the additional service.

323. When trading put options, is your total risk decreased if you are in a position to exercise the option?
In absolute terms the risk is about the same.  If you own the stock and your put option goes in the money, then you have the option to get rid of your stock at yesterday's higher price.  If you don't, you can sell the option for a higher price than you paid for it. But, as you calculated yourself, the net gain or loss (in absolute terms, not percentage terms) is the same either way.

324. Why is it good to borrow money to buy a house?
You can explore the scenarios in which it is better to rent or to buy using this application: http://demonstrations.wolfram.com/BuyOrRentInvestmentReturnCalculator/ In the possibly unlikely scenario shown below, at the term of the mortgage (20 years) the tenant and the buyer have practically the same return on investment.  At this point the tenant's savings would be sufficient to buy a house equivalent to the buyer's, and this would be the advisable course of action (based on the figures alone).

325. Why is it not a requirement for companies to pay dividends?
You have plenty of good answers, but I want to add something that might help you grow your intuition on stocks. There are a lot of differences between the example I am going to give and how the stock market actually runs, but the basic concepts are the same. Lets say your friend asks you if he can borrow some money to start up a company, in exchange you will have some ownership in this company. You have essentially just bought yourself some stock. Now as your friend starts to grow, he is doing well, but he needs more cash to buy assets in order to grow the company more. He is forced with an option, either give you some of the profits, or buy these assets sooner. You decide you don't really need the money right now, and think he can do a lot better with spending the money to buy stuff. This is essentially the same as a company electing to not pay dividends, but instead invest into the future. You as a stock holder are fine with it since you know the money is going toward investing in the future. Even if you never get paid a dividend, as a company grows, you can then turn around and sell the stock to someone else for more money then you gave originally. Of course you always take the risk of having the company failing and loosing some if not all of your investment, but that is just the risk of the market.

326. Should I replace bonds in a passive investment strategy
The fact that some asset (in this case corporate bonds) has positive correlation with some other asset (equity) doesn't mean buying both isn't a good idea.  Unless they are perfectly correlated, the best risk/reward portfolio will include both assets as they will sometimes move in opposite directions and cancel out each other's risk.  So yes, you should buy corporate bonds.  Short-term government bonds are essentially the risk-free asset.  You will want to include that as well if you are very risk averse, otherwise you may not.  Long-term government bonds may be default free but they are not risk free.  They will make money if interest rates fall and lose if interest rates rise.  Because of that risk, they also pay you a premium, albeit a small one, and should be in your portfolio. So yes, a passive portfolio (actually, any reasonable portfolio) should strive to reduce risk by diversifying into all assets that it reasonably can.  If you believe the capital asset pricing model, the weights on portfolio assets should correspond to market weights (more money in bonds than stocks).  Otherwise you will need to choose your weights.  Unfortunately we are not able to estimate the true expected returns of risky assets, so no one can really agree on what the true optimal weights should be.  That's why there are so many rules of thumb and so much disagreement on the subject.  But there is little or no disagreement on the fact that the optimal portfolio does include risky bonds including long-term treasuries. To answer your follow-up question about an "anchor," if by that you mean a risk-free asset then the answer is not really.  Any risk-free asset is paying approximately zero right now.  Some assets with very little risk will earn a very little bit more than short term treasuries, but overall there's nowhere to hide--the time value of money is extremely low at short horizons.  You want expected returns, you must take risk.

327. What percent of my salary should I save?
I disagree with the selected answer. There's no one rule of thumb and certainly not simple ones like "20 cents of every dollar if you're 35". You've made a good start by making a budget of your expected expenses. If you read the Mr. Money Mustache blogpost titled The Shockingly  Simple Math Behind Early Retirement, you will understand that it is usually a mistake to think of your expenses as a fixed percentage of your income. In most cases, it makes more sense to keep your expenses as low as possible, regardless of your actual income.  In the financial independence community, it is a common principle that one typically needs 25-30 times one's annual spending to have enough money to sustain oneself forever off the investment returns that those savings generate (this is based on the assumption of a 7% average annual return, 4% after inflation). So the real answer to your question is this: UPDATE Keats brought to my attention that this formula doesn't work that well when the savings rates are low (20% range). This is because it assumes that money you save earns no returns for the entire period that you are saving. This is obviously not true; investment returns should also count toward your 25-times annual spending goal. For that reason, it's probably better to refer to the blog post that I linked to in the answer above for precise calculations. That's where I got the "37 years at 20% savings rate" figure from. Depending on how large and small x and y are, you could have enough saved up to retire in 7 years (at a 75% savings rate), 17 years (at a 50% savings rate), or 37 years! (at the suggested 20% savings rate for 35-year olds). As you go through life, your expenses may increase (eg. starting a family, starting a new business, unexpected health event etc) or decrease (kid wins full scholarship to college). So could your income. However, in general, you should negotiate the highest salary possible (if you are salaried), use the 25x rule, and consider your life and career goals to decide how much you want to save. And stop thinking of expenses as a percentage of income.

328. Should I open a Roth IRA or invest in the S&P 500?
A Roth IRA is simply a tax-sheltered account that you deposit funds into, and then invest however you choose (within the limits of the firm you deposit the funds with). For example, you could open a Roth IRA account with Vanguard.  You could then invest the $3000 by purchasing shares of VOO, which tracks the S&P 500 index and has a very low expense ratio (0.04 as of last time I checked).  Fidelity has a similar option, or Schwab, or whatever brokerage firm you prefer. IRAs are basically just normal investment accounts, except they don't owe taxes until you withdraw them (and Roth don't even owe them then, though you paid taxes on the funds you deposit).  They have some limitations regarding options trading and such, but if you're a novice investor just looking to do basic investments, you'll not notice.   Then, your IRA would go up or down in value as the market went up or down in value. You do have some restrictions on when you can withdraw the funds; Roth IRA has fewer than a normal IRA, as you can withdraw the capital (the amount you deposited) without penalty, but the profits cannot be withdrawn until you're retirement age (I won't put an actual year, as I suspect that actual year will change by the time you're that old; but think 60s). The reason not to invest in an IRA is if you plan on using the money in the near future - even as an "emergency fund".  You should have some money that is not invested aggressively, that is in something very safe and very accessible, for your emergency fund; and if you plan to buy a house or whatever with the funds, don't start an IRA.  But if this is truly money you want to save for retirement, that's the best place to start. **Note, this is not investment advice, and you should do your own homework prior to making any investment.  You can lose some or all of the value of your account while investing.

329. Is there a limit on the dollar amount of a personal check?
As long as someone is willing to take it, you can write it!  I personally wrote a check for a new car.   The dealership didn't bat an eye.

330. Why don't banks give access to all your transaction activity?
If you need access to your data beyond the online availability, you download the transactions and manage the archive yourself. Six months to eighteen months is generally enough time for most people to manage their own archived data. Big banks have the power to store and retrieve all the data online. Unfortunately, the older records are not frequently accessed. Why have these records online when they will be rarely accessed? Backing up data will take longer. Queries to retrieve data will take longer. Everything will take longer just so you can have records that 99% of customers will never access.

331. Can travel expenses be deducted from Form 1040A if they were used to gather material for a book?
Hobby expenses are not tax deductible.  Business expenses are, but only if it's a bona fide business.  First they look at profitability: if you reported a net profit (i.e. paid taxes) in your first 3 years, they will believe you rant on Youtube for a living.   Remember, by the time they get around to auditing you, you'll likely be well into, or through, your third year.   There is an exception for farms.  Other than that, if you lose money year after year, you better be able to show that you look, walk and quack like a business; and one with a reasonable business reason for delayed profitability.  For instance Netflix's old business model of mailing DVDs had very high fixed infrastructure expense that took years to turn profitable, but was a very sensible model.  They're fine with that.  Pets.com swandived into oblivion but they earnestly tried. They're fine with that too.  You can't mix all your activities. If you're an electrician specializing in IoT and smart homes, can you deduct a trip to the CES trade show, you bet.  Blackhat conference, arguable.  SES?  No way.  Now if you had a second business of a product-reco site which profited by ads and affiliate links, then SES would be fine to deduct from that business.  But if this second business loses money every year, it's a hobby and not deductible at all.  That person would want separate accounting books for the electrician and webmaster businesses.  That's a basic "duck test" of a business vs. a hobby. You need to be able to show how each business gets income and pays expense separate from every other business and your personal life.  It's a best-practice to give each business a separate checking account and checkbook. You don't need to risk tax penalties on a business-larva that may never pupate.  You can amend your taxes up to 3 years after the proper filing date.  I save my expense reciepts for each tax year, and if a business becomes justifiable, I go back and amend past years' tax forms, taking those deductions.  IRS gives me a refund check, with interest!

332. How can I improve my credit score if I am not paying bills or rent?
One of the other things you could do to improve your score would be along the lines of what Pete said in his answer, but using the current financial climate to your advantage. I'm not sure what interest rates are available to you in the UK, but I currently have 4 lines of credit aside from my house. One is a credit card I use for every day purchases and like you pay off immediately with every statement. The other three are technically credit cards, however all three were used to make purchases with 0% financing. The one was for a TV I bought that even gave me 5% off if I pay it off within 6 months. That cash has been sitting in my savings since the day I bought it. I'm making regular payments on all three, but not having to pay any interest. My credit score dropped 25 points with the one as it was an elective medical expense (Visian eye surgery), so for the time the balance is near my credit limit. However, that will bounce back up as the balance lowers. My score was also able to take that hit and still be very high. If you don't have 0% (or very close) available, your better bet would be to follow the other suggestions about saving for a sizable down payment, or other every day expenses like a cell phone.
