967. Options liquidity and trading positions larger than the daily volume?
You definitely cannot be guaranteed to get the bid or ask if you are selling more than are available/desired at those prices. What prices you do get depends on who is watching that contract and how willing they are to trade with you. This question is not much different from the question of whether you can easily get into or out of a large position in an illiquid small stock easily.  You can get out quickly if you are willing to take pennies on the dollar, or you may get a reasonable price if you take a long time to get out of (or into) your position.  You can't normally do both. In general taking large positions in illiquid assets is not something people want to do without lining up a buyer/seller beforehand.  Instead see if you can achieve your objective with liquid investments.

968. What US taxes are due for US stock bought via ESPP when I was in USA and sold after I returned to India?
From an Indian Tax point of view, you can bring back all the assets acquired during the period you were NRI back to India tax free. Subject to a 7 years period. i.e. all the assets / funds / etc should be brought back to India within 7 years. It would still be treated as There are certain conditions / paperwork. Please consult a CA.

969. How much financial information should a buyer give an estate agent?
My guess is they are fishing for business for their in-house finance person. In the UK, all the estate agency chains (and many of the smaller outfits) have financial advice firms they are affiliated with, often to the extent that a desk in each branch will be for 'the finance guy' (it's usually a guy). The moment you show any sign of not quite having the finances for a place you like, they will offer you a consultation with the finance guy, who "will be able to get you a deal". On commission, of course. What you need to say with regards to financing is (delete as applicable) "I am a cash buyer" / "I have an Agreement In Principle". And that's it. They do not 'need' to know any more, and they are under obligation to pass your offer on to the vendor.

970. What happens if a company I have stock in is bought out?
I've seen many buyouts in my own portfolio, including the company I worked for.  There have been several different scenarios: The terms of the deal are subject to the deal -- frankly whatever makes sense to the buyer and that is accepted by the seller. So sometimes brokers charge reorganization fees.  check into those for your broker.  I've not seen one in a while, but my brokerage account is substantial, and often that's a perk they offer higher-value accounts. Also watch out for taxes.  The transaction where my employer was bought by another publicly traded company -- we got bit because the IRS treated it as a taxable transaction, and all our RSUs were effectively sold and then repurchased.  So we ended up with a big tax bill (capital gains) without any cash to offset the big tax bill.  I suspect its because my old employer was a US based company, whereas the new company is not.

971. Are Index Funds really as good as “experts” claim?
Simply put, you cannot deterministically beat the market. If by being informed and following all relevant news, you can arrive at the conclusion that company A will likely outperform company B in the future, then having A stocks should be better than having B stocks or any (e.g., index based) mix of them. But as the whole market has access to the very same information and will arrive at the same conclusion (provided it is logically sound), "everybody" will want A stocks, which thus become expensive to the point where the expected return is average again.  Your only options of winning this race are to be the very first to have the important information (insider trade), or to arrive at different logical conclusions than the rest of the world (which boils down do making decisions that are not logically sound - good luck with that - or assuming that almost everybody else is not logically sound - go figure).

972. Wage earners of age ≥ 60 with dependents: What Life Insurance, if any, should they buy?
The problem above is actually a pretty good list of the concerns around life insurance.  While there is no correct answer to the question as posed, this will vary among different WSCs, there is a simpler way to think about insurance in general that may make finding what is right answer for you easier. Buying life insurance, like almost all insurance, is on average a money losing purchase.  This is simply because the companies selling wouldn't offer it if they couldn't expect to make money on it.  Think about buying insurance (a warranty) on a new cell phone, maybe if you are particularly prone to damaging cell phones it can be in your favor, but for most of the people that buy it will lose money on average. People, of course, still buy insurance anyway to protect themselves from unlikely but very bad consequences.  The big reason to make this trade off is if the loss will have big lasting consequences.  To stay with our cell phone example having to replace a cell phone, at least for me, would be annoying but not a catastrophic event.  For myself, the protection is not worth the warranty cost, but that is not true for everyone. Life insurance is a pretty extreme case of this, but I find the best question to ask is "if you (you and your spouse) were to die will your dependents lives become so much worse that you really dislike the idea of not being insured?" For some working seniors, they already have enough saved to bridge their kids/spouse to adulthood/old-age that insurance makes no sense.  For some, their children/husband/wife would be destitute and insurance is an obvious choice and an easy price to pay even if it is very high.  The example you suggest seems on the border and good questions to ask are: Thinking about those questions may help you understand if the protection offers is worth the cost.

973. Does the IRS reprieve those who have to commute for work?
No.  Regular W2 employees cannot deduct housing or transportation costs related to their employment.   However, in the US, many employers offer Parking and/or Transit FSA programs which are usually collectively referred to a Commuter Benefits FSA programs, this is particularly common among larger employers with locations in major metropolitan cities.  Under Commuter benefits FSAs employees can defer up to $255 per month from their gross pay, tax-free, for parking and/or transit expenses.  Eligible expenses include things like bus and train passes or parking at a train or bus station.  These are money-in/money-out arrangements so expenses can only be claimed against contributions that have been made, unlike a Health FSA.  Though, like a health FSA, contributions are subject to use-it or lose-it provisions. These programs must be sponsored by the employer for an employee to take advantage of them though.  Some jurisdictions mandate that employers above a certain threshold must offer commuter benefits.

974. Iraqi Dinars. Bad Investment, or Worst Investment?
Iraq is a US vassal/puppet state. I'm not sure what 500 South Vietnamese Dong were worth in 1972, but today the paper currency is worth $10 in mint condition. I'd suggest blackjack or craps as an alternate "investment".

975. What evidence exists for claiming that you cannot beat the market?
Will the investor beat the benchmark for a given period will follow a Bernoulli distribution -- each period is a coin toss, and heads mean the investor beat the market for that period.   I can't prove the negative that there is no investor ever whose probability function p = 1, but you can statistically expect a number of individual investors with p ~ 0.5 to have a sequence of many heads in a row, as a function of the total population.   By example, my father explained investment scams and hot-hand theory to me this way when I was younger:  Imagine an investor newsletter which mails out to a mailing list of 1024 prospects (or alternately, a field of 1024 amateur investor bloggers in a challenge).  Half the letters or bloggers state AAPL will go up this week, half that AAPL will go down this week.  In the newsletter case, next week ignore the people we got wrong.  In the blogger case, they're losers, so we don't pay attention to them.  Next week, similar split: half newsletters or bloggers claim GOOG go up, half GOOG go down.  This continues for a 10 week cycle.   Now, in week 10: the newsletter has a prospect they have hit correct 10x in a row: how much will he pay for a subscription?  Or, one amateur investor blogger has been on a 10 week winning streak and wins the challenge, so of course let's give her a CNBC show after Jim Cramer.  No matter what, next week, this newsletter or investor is shooting 50-50.   How do you know this person is not the statistically expected instance backed up by a pyramid of 1023 Bernoulli distribution losers?  Alternately, if you think you're going to be the winner, you've got a 1/1024 shot.

976. How to have a small capital investment in US if I am out of the country?
For $100 you better just hold it in Mexico.  The cost of opening an account could eat 10% or more of your capital easily, and that won't be able to buy enough shares of an ETF or similar investment to make it worthwhile.

977. Explanations on credit cards in Canada
I think it's worth pointing out explicitly that the biggest difference between a credit card (US/Canada) and a debit card (like your French carte de crédit) is that with a credit card, it's entirely possible to not pay the bill or to pay only the "minimum payment" when asked. This results in you owing significantly more money due to interest, which can snowball into higher and higher levels of debt, and end up getting rapidly out of control. This is the reason why you should ALWAYS pay off the ENTIRE balance every month, as attested to in the other answers; it's not uncommon to find people in the US with thousands of dollars of debt they can't pay off from misuse of credit cards.

978. Do I need a business credit card?
I would try to avoid mixing business expenditure with personal expenditure so a second credit card might be a good idea. That said, I did get a business credit card for my company in the UK as I didn't want to be personally liable for the money that was spent on the business card (even though I owned 100% of the business) in case things went horribly wrong. As I didn't fancy signing a personal guarantee, this meant that the limit was quite low but it was good enough in most cases.

979. Does a falling dollar mean doom for real estate?
A falling $AUD would be beneficial to exporters, and thus overall good for the economy. If the economy improves and exporters start growing profits, that means they will start to employ more people and employment will increase - and with higher employment, employees will become more confident to make purchases, including purchasing property. I feel the falling $AUD will be beneficial for the economy and the housing market. However, what you should consider is that with an improving economy and a rising property market, it will only be a matter of time before interest rates start rising. With a lower $AUD the RBA will be more confident in starting to increase interest rates. And increasing interest rates will have a dampening effect on the housing market. You are looking to buy a property to live in - so how long do you intend to live in and hold the property? I would assume at least for the medium to long term. If this is your intention then why are you getting cold feet? What you should be concerned about is that you do not overstretch on your borrowings! Make sure you allow a buffer of 2% to 3% above current interest rates so that if rates do go up you can still afford the repayments. And if you get a fixed rate - then you should allow the buffer in case variable rates are higher when your fixed period is over. Regarding the doomsayers telling you that property prices are going to crash - well they were saying that in 2008, then again in 2010, then again in 2012. I don't know about you but I have seen no crash. Sure when interest rates have gone up property prices have levelled off and maybe gone down by 10% to 15% in some areas, but as soon as interest rates start falling again property prices start increasing again. It's all part of the property cycle.  I actually find it is a better time to buy when interest rates are higher and you can negotiate a better bargain and lower price. Then when interest rates start falling you benefit from lower repayments and increasing property prices. The only way there will be a property crash in Australia is if there was a dramatic economic downturn and unemployment rates rose to 10% or higher. But with good economic conditions, an increasing population and low supplies of newly build housing in Australia, I see no dramatic crashes in the foreseeable future. Yes we may get periods of weakness when interest rates increase, with falls up to 15% in some areas, but no crash of 40% plus. As I said above, these periods of weakness actually provide opportunities to buy properties at a bit of a discount. EDIT In your comments you say you intend to buy with a monthly mortgage repayment of $2500 in place of your current monthly rent of $1800. That means your loan amount would be somewhere around $550k to $600K. You also mention you would be taking on a 5 year fixed rate, and look to sell in about 2 years time if you can break even (I assume that is break even on the price you bought at). In 2 years you would have paid $16,800 more on your mortgage than you would have in rent. So here are the facts: A better strategy:

980. Is gold really an investment or just a hedge against inflation?
Over on Quantitative Finance Stack Exchange, I asked and answered a more technical and broader version of this question, Should the average investor hold commodities as part of a broadly diversified portfolio?  In short, I believe the answer to your question is that gold is neither an investment nor a hedge against inflation. Although many studies claim that commodities (such as gold) do offer some diversification benefit, the most credible academic study I have seen to date, Should Investors Include Commodities in Their Portfolios After All? New Evidence, shows that a mean-variance investor would not want to allocate any of their portfolio to commodities (this would include gold, presumably). Nevertheless, many asset managers, such as PIMCO, offer funds that are marketed as "real return" or "inflation-managed" and include commodities (including gold) in their portfolios.  PIMCO has also commissioned some research, Strategic Asset Allocation and Commodities, claiming that holding some commodities offers both diversification and inflation hedging benefits.

981. How do credit card banks detect fraudulent transactions without requiring a travel advisory?
One bank is more willing to risk losses and customer hassle in exchange for lower processing costs than the other bank is. It's strictly a business decision. Regarding how they detect suspicious transactions: Patten detection based on your past usage history. I've gotten calls asking me to confirm that I just placed a large order with a company I'd never bought from before, or in a country that I haven't previously visited, or...

982. How does a tax exemption for an action = penalty for inaction?
What it means is that you can always come up with alternative framings where the difference between two options is stated as a gain or a loss, but the effect is the same in either case.  For instance, if I offer to sell a T-shirt for $10 and offer a cash discount of $1, you pay $10 if buying with a credit card or $9 if buying with cash.  If I instead offer the shirt for $9 with a $1 surcharge for credit card use, you still pay $10 if buying with a credit card or $9 if buying with cash.  The financial result is the same in either case, but psychologically people may perceive them differently and make different buying decisions. In a tax situation it may be more complicated since exemptions wouldn't directly reduce your tax, but only your taxable income.  However, you can still see that, in general, having to pay $X more in tax for not doing some action (e.g., not purchasing health insurance) is the same as being able to pay $X less in tax as a reward for doing the action.  Either way, doing the action results in you paying $X less than you would if you didn't do it; the only difference is in which behavior (doing it or not doing it) is framed as the "default" option.  Again, these framings may differentially influence people's behavior even when the net result is the same.
