717. How do you find out who the investors are in a U.S. stock? e.g. how ownership may be concentrated?
I don't think that you will be able to find a list of every owner for a given stock. There are probably very few people who would know this. One source would be whoever sends out the shareholder meeting mailers.  I suspect that the company itself would know this, the exchange to a lesser extent, and possibly the brokerage houses to a even lesser extent. Consider these resources:

718. How it actually works? Selling a call on a stock I hold, but has done poor, might the market thinks may rise
What you are proposing is called a "covered call" strategy.  It is a perfectly reasonable speculative play on how far the stock will move within a certain amount of time.  If your belief that the stock's volatility is such that it is unlikely to reach the strike price before the maturity is greater than the markets (which it seems it is), then go ahead and sell the call.

719. Why do people buy insurance even if they have the means to overcome the loss?
For a car, you're typically compelled to carry insurance, and picking up "comprehensive" coverage (fire, theft, act of god) is normally cheap. If the car was purchased with a loan, the lender will stipulate that you carry comprehensive and collision insurance.  People buy insurance because it limits their liability. In the grand scheme of things, pricing in a fixed rate of loss every year (insurance premium + potential deductible) is appealing to many versus having to cover a catastrophic loss when your car is wrecked or stolen.

720. Why doesn't buy at open get the official open price?
There is no official price. There is only the price a seller is willing to offer and a buyer is willing to accept at that moment. It tends to be close to the price negotiated for the last such sale, but that's just market statistics, not anything actively managed or guaranteed. "Past performance is no guarantee of future results;" this buyer and seller may not agree with the previous pair. Especially when the market has been closed overnight but real-world events have continued to occur.

721. How to increase my credit score
Get a credit card is NOT the answer. The reason people have a bad (or no) credit score is often because they're new to the country, have just turned 18, have previously fallen into arrears or are just bad with money. Getting a credit card is risky because, if you don't stay on top of your payments, it'll just damage your score even more.  Now, it sounds like I hate credit cards - but I don't, and they do have their benefits. But avoid them if possible because they can be more hassle than they're worth (ie, paying the credit back on-time, cancelling accounts when the interest comes in, moving money in and out of accounts). It's risky borrowing money from anywhere whether it's a payday lender, a bank, a credit card, etc., so use them as a last resort. If you've got your own income then that's amazing!, try not to live outside of your means and your credit score will look after (and increase) itself. It takes time to build a good credit score, but always make sure you pay the people you owe on time and the full amount. I'd stick with paying your phone provider (and any other direct debits you have setup) and avoid getting a credit card. I'd recommend Noddle to keep track of your credit score and read their FAQ on how to help build it. Unlike Experian, it's free forever so not quite as detailed... but Noddle are owned by CallCredit - one of the biggest Credit Reference Agencies in the UK so they should have the latest information on yourself. In conclusion, if you already have financial commitments like a mobile phone bill, gym membership, store cards, anything that gets paid monthly by direct debit... your credit score will increase (provided you pay the full-amount on time).   I hope this helps. PS. I don't work for any of the companies here, but I've been working in the finance sector (more specifically, short-term loans) for 3+ years now.

722. Why do I see multiple trades of very small quantities?
It looks more like someone is trying to pocket the spread.  The trades are going off at the bid then the ask (from what I can tell without any L1 and L2 data, but the spread could be bigger than what the prices show, since the stock looks pretty volatile given the difference between current price and VWAP...).  Looking through the JSE rule books I didn't find any special provisions on how they handle odd lots in their Central Order Book, but the usual practice in other markets is to display only round lot orders. So these 4 share orders would remain hidden from book participants and could be set there to trigger executions from those who are probing for limit orders. Or to make a market with very limited risk.

723. How to save money for future expenses
First, talk to your husband about this. You really need to persuade him that you need to be saving, and get him to agree on how and how much. Second, if you husband is not good at saving, work on getting something set aside automatically - ideally deducted from a paycheck or transferred to a savings account automatically. If he is the kind of person who might dip into that account, try to make it a place he can't withdraw from Third, get some advice, possibly training, on budgeting. Buy a book, take a video course: even start by watching some TV shows on getting out of debt.

724. Is it wise to switch investment strategy frequently?
A guy who does a sports talk show here in the US can be pretty smart about some things.  His advice:  If you are wondering if something is a good idea, say it out loud.  In his book he cites the fact that people thought, at one time, it would be a good idea to allow smoking on airline flights.  Keep in mind you are using liquid oxygen, news paper, and are 10,000+ feet up in the air.  Say it like that and you hit yourself in the forehead. Read the title of your question in a day or two, and you can answer it yourself with a resounding NO.

725. In the stock market, why is the “open” price value never the same as previous day's “close”?
Nobody has mentioned the futures market yet. Although the stock market closes at 4pm, the futures market continues trading 24 hours a day and 5.5 days a week. Amongst the products that trade in the future market are stock index futures.  That includes the Dow Jones, the S&P 500. These are weighted averages of stocks and their sectors. You would think that the price of the underlying stock dictates the price of the average, but in this day and age, the derivative actually changes the value of the underlying stock due to a very complex combination of hedging practices. (this isn't meant to be vague and mysterious, it is "delta hedging") So normal market fluctuations coupled with macroeconomic events affect the futures market, which can ripple down to individual stocks. Very popular stocks with large market caps will most certainly be affected by futures market trading. But it is also worth mentioning that futures can function completely independently of a "spot" price. This is where things start to get complicated and long winded. The futures market factor is worth mentioning because it extends even outside of the aftermarket and pre-market hours of stock trading.

726. Online tools for monitoring my portfolio gains/losses in real time?
This functionality is widely available, not only on brokerage sites, but also financial management and even financial information sites.  For instance, two of the latter are Google Finance and Yahoo Finance.  If you are logged in, they let you create "portfolios" listing your stocks and, optionally, the size of your holdings in that stock (which you don't need if you are just "watching" a stock).  Then you can visit the site at any time and see the current valuations.

727. Shares Canceled after Merger
It seems like this was a "stock for stock" transaction. That is, your company was acquired, not for cash, but for the stock of Company X in a deal that your company's board of directors "signed off" on.  Your company no longer exists, and that's why your stock was cancelled. The acquirer will be sending you an equivalent amount of stock in their Company, X. You don't need to worry about taxes, only accounting, because this is a "non-cash" transaction. What this means that your cost basis in the stock of Company X will be what you paid for the original company's stock (not its value on the day of the merger, which may be higher or lower than what you paid).

728. How do I apply for a mortgage after a cash closing on a property?
Is she correct in that you generally can't even apply until the cash   transaction is complete? Probably. How can you commit to mortgage something you do not own? Makes sense for them to wait not even until the transaction is complete - but until the transaction is recorded. Is 45 days reasonable to complete the financing? Yes.

729. How fast does the available amount of gold in the world increase due to mining?
If that fraction is really small, then the amount of gold can be thought of as relatively constant. That fraction is very small. After all, people have been mining gold for thousands of years. So the cumulative results of gold mining have been building up the supply for quite some time. Meanwhile, owners of gold rarely destroy it. A little bit of gold is used in some industries as a consumable. This limited consumption of gold offsets some of the production that comes from mining. But truthfully this effect is minuscule. For the most part people either hoard it like its made of gold, or sell it (after all it is worth its weight in gold). If you're interested Wikipedia lists a few more factors that affect gold prices. (If you're not interested Wikipedia lists them anyway.)

730. Self-directed RRSP into mortgage investment
The Globe and Mail has an interesting article on what you can do with your RRSPs. Be aware that the article is from early 2011 and rules change. They describe holding your own mortgage inside your RRSP. That is, if you have $100,000 inside your RRSP already and your remaining mortgage is $100,000, you can use that money to pay off your mortgage, then pay back the money at interest, generating a tax-deferred profit inside your RRSP. That approach may be viable, though you'd want to talk to your accountant first. I'd be very cautious about loaning money to someone else for a second mortgage using my RRSP, though. Second mortgages are inherently risky, so this is a very speculative investment. Once you make an RRSP contribution, that space is used up (barring a couple of exceptions such as the life-long learning plan). So, let's say you used $100,000 of your RRSP to loan to someone for a second mortgage. Any interest payments should be sheltered inside the RRSP (substantial benefit), but if the person defaults on the second mortgage (which you should expect to be a significant possibility), you've lost your entire $100,000 contribution room (as well as, obviously, the $100,000 that you loaned out). I can't tell you whether or not it makes sense to invest in risky second-mortgage loans and I can't tell you whether, if you choose to do so, it definitely should be done inside an RRSP. There are substantial risks in the loan and there are both costs and benefits to doing so inside an RRSP. Hopefully, though, I've helped you understand the questions you should be asking yourself.

731. Can the Securities Investor Protection Corporation (SIPC) itself go bankrupt?
Not sure if I follow your question completely. Re: What if some fraud takes place that's too big even for it to fund?   SIPC does not fund anything. What it does is takes over the troubled brokerage firm, books / assets and returns the money faster. Refer to SIPC - What SIPC Covers... What it Does Not and more specifically SIPC - Why We Are Not the FDIC. SIPC is free for ordinary investors. To get the same from elsewhere one has to pay the premium. Edit: The event we are saying is a large brokrage firm, takes all of the Margin Money from Customer Accounts and loses it and also sell off all the stocks actually shown as being held in customer account ... that would be to big. While its not clear as to what exactly will happens, my guess is that the limits per customers will go down as initial payments. Subsequent payments will only be done after recover of funds from the bankrupt firm. What normally happens when a brokrage firm goes down is some of the money from customers account is diverted ... stocks are typically safe and not diverted. Hence the way SIPC works is that it will give the money back to customer faster to individuals. In absence of SIPC individual investors would have had to fight for themselves.

732. Buying a car and learning to drive versus paying up study loans
Welcome to Money.SE. It appears there's public transportation to get you to work? And the area by your house is walkable? i.e. you and your wife can get groceries and other needs by walking. If it will take 5 years to pay the loans even without a car, how long if you get one? Will you even be able to afford the payments?  There's not enough detail here except to say that all purchases aside from true needs have a cost/reward to consider. Whatever the car's total cost is, will it add that much pleasure to your life? People in cities with great transportation save quite a bit on the expenses a car brings.  Personal anecdote - Mom lives in a city. She never drives out of the city. Ever. Between insurance, maintenance, and gas, even with low miles, she spends $3000/yr. Once per week, she drives 1500 ft (.3mi) each way to the grocery store. Once every month or 2 to a mall 6 miles away. She can walk and groceries delivered for free. In the end, she spends $250/mo for the feeling of freedom. I get that. When I am 70+, as she is, I will gladly pay car service the $20 to drive me around.  You are young, and need to sit with your partner (your wife is your partner in the business of running the family finances, or so I hope) and decide if the benefit is worth the cost. How does she take the kids to a doctor? How do you go out to dinner?
