333. Do I have to pay a capital gains tax if I rebuy different stocks?
Probably.  It sounds like you're looking for a 1031-exchange for stocks and bonds.  From the wikipedia page for 1031-exchanges: To qualify for Section 1031 of the Internal Revenue Code, the properties exchanged must be held for productive use in a trade or business or for investment. Stocks, bonds, and other properties are listed as expressly excluded by Section 1031 of the Internal Revenue Code, though securitized properties are not excluded.  1031-exchanges usually are applicable in real estate.

334. Why don't banks give access to all your transaction activity?
Although if you count only your data, it would be quite less 10 MB, multiply this by 1 million customers and you can see how quickly the data grows. Banks do retain data for longer period, as governed by country laws, typically in the range of 7 to 10 years.  The online data storage cost is quite high 5 to 10 times more than offline storage. There are other aspects, Disaster recover time, the more the data the more the time. Hence after a period of time Banks move the data into Archive that are cheaper to store but are not available to online query, plus the storage is not optimized for search. Hence retrieval of this data often takes few days if the regulator demands or court or any other genuine request for data retrieval.

335. Assessed value of my house
You said the tax assessor gave you an appraised value, but I think you mean assessed value. This article YOUR HOME; Market vs. Appraisal: What's the Real Value? explains the differences pretty well.

336. Avoid Capital Gains on Rental
Your question is best asked of a tax expert, not random people on the internet. Such an expert will help you ask the right questions.  For example you did not point out the country or state in which you live.  That matters.   First point is that you will not pay tax on 60K, its expensive to transact real estate, so your net proceeds will be closer to 40K.  Also you can probably the deduct the costs of improvements. You implied that you really like this rental property.  If that is the case, why would you sell...ever?  This home could be a central part of your financial independence plan.  So keep it until you die.  IIRC when it passes to your heirs, a new cost basis is formed thereby not passing the tax burden onto them. (Assuming the property is located in the US.)

337. Should I get an accountant for my taxes?
Let me offer an anecdote to this -  I started helping a woman, widowed, retired, who had been paying $500/yr to get her taxes done. As I mentioned in my comment here, she got a checklist each year and provided the info requested. From where I sat, it seemed a clerk entered the info into tax software.  As part of the transition to me helping her, I asked the prior guy (very nice guy, really) for a quick consult. She took the standard deduction, but also showed a nice annual donation. Didn't take advantage of the QCD, donate directly from an IRA (she was over 70-1/2) to save on the tax of this sum. That could have saved her $500.  She was in the 15% bracket, with some room left for a Roth conversion. Converting just enough to 'fill' that bracket each year seemed a decent strategy as it would avoid the 25% rate as her RMDs rose each year and would push her to 25%. To both items the guy suggested that this was not his area, he was not a financial planner. Yes, I understand different expertise. With how simple her return was, I didn't understand the value he added.  If you go with a professional, be sure you have an understanding of what he will and won't do for you.

338. Do Square credit card readers allow for personal use?
What I should have done in the first place was just ask them.  From their customer support team: Thanks for writing in and for your interest in Square. It is perfectly acceptable to use Square for personal business, such as a yard sale. You do not need to have a registered business to take advantage of Square and the ability to accept credit cards. Just please note that it is against our Terms of Service to process prepaid cards, gift cards or your own credit card using your own Square account. Additionally, you may not use Square as a money transfer system. For every payment processed through Square, you must provide a legitimate good or service. Please let me know if you have any additional concerns.

339. Does an employee have the right to pay the federal and state taxes themselves instead of having employer doing it?
No, even businesses pay taxes quarterly.  So if you formed Nathan, LLC, or otherwise became self employed, you'd still have to file quarterly estimates and make tax payments.  This would cause taxes to be a much more high touch part of your life. However, you should ensure that you're claiming the proper exemptions etc to avoid excessive withholding.

340. Investing in dividend-yielding stocks with money borrowed from margin account?
Is it safe to invest in a portfolio of dividend stocks yielding 7-9% with the money borrowed at 3-4% from one of these brokerages? Yes and no. It depends on your risk profile! Any investment has its risks of losing your capital, but not investing is a guaranteed risk, as you will be guaranteed to fall behind the rate of inflation. Regarding investing on margin, this can increase your gains but can also increase your loses. Regarding the stock market - when investing in stocks you should not only look at the dividend rate but also the capital gain or loss potential. Remember in regards to investing on margin, if the share price drop too much you can get a margin call no matter how much dividend you are getting. It is no use gaining 9% in dividend yield per year if you are losing 15% or more in capital each year. Also, what is the risk of the dividend rate being cut back or dividends not being paid at all in the future? These are some of the risks you should consider before investing and derive a risk management plan as part of your investment plan before you invest. No investment is totally safe or risk free, but it is less risky than not investing at all, as long as you understand the risks involved and have a risk management plan in place as part of your overall investment plan.

341. Foreign Earned Income Exclusion - Service vs. Product?
As the name says, its for income earned in a Foreign country. If you have been paying US income tax on this while living in the US, nothing is going to change here. You should be informing yourself on how to avoid double taxation in your new country of residence. Passive income earned abroad (dividends, interest) also do not fall under this exemption.  The purpose of the Foreign Earned Income Exclusion is to make it easy for expats who work abroad to avoid double income taxation without going through the complicated process of applying for tax credits. The US is the only industrial country that taxes its residents regardless of where they reside. That is also why it only goes to about $100,000 a year. If you are a high earner, they want to make it more difficult. Also as a side note, since you are going to be abroad for a year. I will point out that if you have more than $10,000 in foreign accounts at any point in the year you need to declare this in an FBAR form. This is not advertised as well as it should be and carries ridiculous penalties for non-compliance. I can't count the number of times I have heard a US expat say that they were unaware of this.

342. Dormant company, never paid taxes, never traded in UK - should I have notified the HMRC?
You don't have to register for corporation tax until you start doing business: After you’ve registered your company with Companies House, you’ll need to register it for Corporation Tax. You’ll need to do this within 3 months of starting to do business. Since you haven't needed to do that yet, there also shouldn't be any need to tell HMRC you've stopped trading. So it should just be a question of telling Companies House - I guess it's possible they'll first want you to provide the missing accounts.

343. Why do some people go through contortions to avoid paying taxes, yet spend money on expensive financial advice, high-interest loans, etc?
To some extent, I suppose, most people are okay with paying Some taxes. But, as they teach in Intro to Economics, "Decisions are made on the margin". Few are honestly expecting to get away with paying no taxes at all. They are instead concerned about how much they spend on taxes, and how effectively. The classic defense of taxes says "Roads and national defense and education and fire safety are all important." This is not really the problem that people have with taxes. People have problems with gigantic ongoing infrastructure boondoggles that cost many times what they were projected to cost (a la Boston's Big Dig) while the city streets aren't properly paved. People don't have big problems with a city-run garbage service; they have problems with the garbagemen who get six-figure salaries plus a guaranteed union-protected job for life and a defined-benefit pension plan which they don't contribute a penny to (and likewise for their health plans). People don't have a big problem with paying for schools; they have a big problem with paying more than twice the national average for schools and still ending up with miserable schools (New Jersey). People have a problem when the government issues bonds, invests the money in the stock market for the public employee pension plan, projects a 10% annual return, contractually guarantees it to the employees, and then puts the taxpayers on the hook when the Dow ends up at 11,000 instead of ~25,000 (California). And people have a problem with the attitude that when they don't pay taxes they're basically stealing that money, or that tax cuts are morally equivalent to a handout, and the insinuation that they're terrible people for trying to keep some of their money from the government.

344. Invest all at once after maxing out Roth IRA - or each time I contribute?
If you are like most people, your timing is kind of awful.  What I mean by most, is all.  Psychologically we have strong tendencies to buy when the market is high and avoid buying when it is low.  One of the easiest to implement strategies to avoid this is Dollar Cost Averaging.  In most cases you are far better off making small investments regularly. Having said that, you may need to "save" a bit in order to make subsequent investments because of minimums.   For me there is also a positive psychological effect of putting money to work sooner and more often.  I find it enjoyable to purchase shares of a mutual fund or stock and the days that I do so are a bit better than the others.   An added benefit to doing regular investing is to have them be automated.  Many wealthy people describe this as a key to success as they can focused on the business of earning money in their chosen profession as opposed to investing money they have already earned.  Additionally the author of I will Teach You to be Rich cites this as a easy, free, and key step in building wealth.

345. Is the average true range a better measure of volatility than historical volatility
ATR really looks at the volatility within the day -- So you would be able to see if the stock is becoming more or less volatile in daily trading.  This is often useful for charting and finding entry and exit locations.   Traditional historic volatility (as you cited) will give you a look at the long term volatility of the security.  The example of this is that there could be trends up or down but the same daily volatility (same ATR) There are methods that try to incorporate both intraday information along with historic volatility.  As for which is a better measure of volatility-- it depends on what you are using the measure for.

346. Is buying a lottery ticket considered an investment?
Although this has been touched upon in comments, I think the following line from the currently accepted answer shows the biggest issue: There is a clear difference between investing and gambling. The reality is that the difference isn't that clear at all. Tens of comments have been written arguing in both directions and looking around the internet entire essays have been written arguing both positions. The underlying emotion that seems to shape this discussion primarily is whether investing (especially in the stock market) is a form of gambling. People who do invest in this way tend to get relatively emotional whenever someone argues that this is a form of gambling, as gambling is considered a negative thing. The simple reality of human communication is that words can be ambiguous, and the way investors will use the words 'investments' and 'gambles' will differ from the way it is used by gamblers, and once again different from the way it's commonly used. What I definitely think is made clear by all the different discussions however is that there is no single distinctive trait that allows us to differentiate investing and gambling. The result of this is that when you take dictionary definitions for both terms you will likely end up including lottery tickets as a valid form of investment.  That still however leaves us with a situation where we have two terms - with a strong overlap - which have a distinctive meaning in communication and the original question whether buying lottery tickets is an investment. Over on investorguide.com there is an absolutely amazing strongly recommended essay which explores countless of different traits in search of a difference between investing and gambling, and they came up with the following two definitions: Investing: "Any activity in which money is put at risk for the purpose of making a profit, and which is characterized by some or most of the following (in approximately descending order of importance): sufficient research has been conducted; the odds are favorable; the behavior is risk-averse; a systematic approach is being taken; emotions such as greed and fear play no role; the activity is ongoing and done as part of a long-term plan; the activity is not motivated solely by entertainment or compulsion; ownership of something tangible is involved; a net positive economic effect results." Gambling: "Any activity in which money is put at risk for the purpose of making a profit, and which is characterized by some or most of the following (in approximately descending order of importance): little or no research has been conducted; the odds are unfavorable; the behavior is risk-seeking; an unsystematic approach is being taken; emotions such as greed and fear play a role; the activity is a discrete event or series of discrete events not done as part of a long-term plan; the activity is significantly motivated by entertainment or compulsion; ownership of something tangible is not involved; no net economic effect results." The very interesting thing about those definitions is that they capture very well the way those terms are used by most people, and they even acknowledge that a lot of 'investors' are gambling, and that a few gamblers are 'investing' (read the essay for more on that). And this fits well with the way those two concepts are understood by the public. So in those definitions normally buying a lottery ticket would indeed not be an investment, but if we take for example Vadim's operation example If you have $1000 and need $2000 by next week or else you can't have an operation and you will die (and you can't find anyone to give you a loan). Your optimal strategy is to gamble your $1000, at the best odds you can get, with a possible outcome of $2000. So even if you only have a 1/3 chance of winning and getting that operation, it's still the right bet if you can't find a better one. this can suddenly change the perception and turn 'gambling' into 'high-risk investing'.

347. Why I cannot find a “Pure Cash” option in 401k investments?
There is no zero risk option! There is no safe parking zone for turbulent times! There is no such thing as a zero-risk investment.  You would do well to get this out of your head now.  Cash, though it will retain its principle over time, will always be subject to inflation risk (assuming a positive-inflation environment which, historically in the US anyway, has always been the case since the Great Depression). But I couldn't find a "Pure Cash - No investment option" - what I mean by this is an option where my money is kept idle without investing in any kind of financial instrument (stocks, bonds, other MFs, currencies, forex etc etc whatever).  Getting back to the real crux of your question, several other answers have already highlighted that you're looking for a money market fund.  These will likely be as close to cash as you will get in a retirement account for the reasons listed in @KentA's answer. Investing in short-term notes would also be another relatively low-risk alternative to a money market fund.  Again, this is low-risk, not no-risk. I wanted such kinda option because things may turn bad and I may want nothing invested in the stock markets/bond markets. I was thinking that if the market turns bear then I would move everything to cash Unless you have a the innate ability to perfectly time the market, you are better off keeping your investments where they are and riding out the bear market.  Cash does not generate dividends - most funds in a retirement account do.  Sure, you may have a paper loss of principle in a bear market, but this will go away once the market turns bull again.  Assuming you have a fairly long time before you retire, this should not concern you in the slightest. Again, I want to stress that market timing does not work.  Even the professionals, who get paid the big bucks to do this, on average, get it right as often as they get it wrong.  If you had this ability, you would not be asking financial questions on Stack Exchange, I can tell you that. I would recommend you read The Four Pillars of Investing, by William Bernstein.  He has a very no-nonsense approach to investing and retirement that would serve you (or anybody) well in turbulent financial markets.  His discussion on risk is especially applicable to your situation.

348. How are stock buybacks not considered insider trading?
In fact, buybacks WERE often considered a vehicle for insider trading, especially prior to 1982.  For instance, Prior to the Reagan era, executives avoided buybacks due to fears that   they would be prosecuted for market manipulation. But under SEC Rule   10b-18, adopted in 1982, companies receive a “safe harbor” from market   manipulation liability on stock buybacks if they adhere to four   limitations: not engaging in buybacks at the beginning or end of the   trading day, using a single broker for the trades, purchasing shares   at the prevailing market price, and limiting the volume of buybacks to   25 percent of the average daily trading volume over the previous four   weeks.

349. How to prevent myself from buying things I don't want
I use cash exclusively. I go to the cash machine once a week and withdraw the money I want to spend in one week (so I have to plan if I want to buy something expensive). Otherwise I leave the card at home. As bonus you get anonymity, i.e. big brother cannot track you.
