Is there a way to tell how many stocks have been shorted?
Generally the number of shares of a U.S. exchange-listed stock which have been shorted are tracked by the exchange and reported monthly.  This number is usually known as the open short interest.  You may also see a short interest ratio, which is the short interest divided by the average daily volume for the stock. The short interest is available on some general stock data sites, such as Yahoo Finance (under Key Statistics) and dailyfinance.com (also on a Key Statistics subpage for the stock).
"1 - in most cases, the difference between filing joint or married filing single is close to zero. When there is a difference you're better off filing joint.  2 - The way the W4 works is based on how many allowances you claim. Unfortunately, even in the day of computers, it does not allow for a simple ""well my deduction are $xxx, don't tax that money."" Each allowance is equal to one exemption, same as you get for being you, same as the wife gets, same as each kid. 3 people X $3800 = $11,400 you are telling the employer to take off the top before calculating your tax. She does this by using Circular E and is able to calculate your tax as you request. If one is in the 15% bracket, one more exemption changes the tax withheld by $570. So if you were going to owe $400 in April, one few exemption will have you overpay $170. i.e. in this 15% bracket, each exemption changes annual withholding by that $570.  For most people, running the W4 numbers will get them very close, and only if they are getting back or owing over $500, will they even think of adjusting.  3 - My recently published Last Minute Tax Moves offers a number of interesting ideas to address this. The concept of grouping deductions in odd years is worth noting.  4 - I'm not sure what this means, 2 accounts each worth $5000 should grow at the same rate if invested the same. The time it makes sense to load one person's account first is if they have better matching. You say you are not sure what percent your wife's company matches. You need to change this. For both of your retirement plans you need to know every detail, exact way to maximize matching, expense ratios for the investments you choose, any other fees, etc. Knowledge is power, and all that. In What is an appropriate level of 401k fees or expenses in a typical plan? I go on to preach about how fees can wipe out any tax benefit over time. For any new investor, my first warning is always to understand what you are getting into. If you can't explain it to a friend, you shouldn't be in it.  Edit - you first need to understand what choices are within the accounts. The 4% and 6% are in hindsight, right? These are not fixed returns. You should look at the choices and more heavily fund the account with the better selection. Deposit to her account at least to grab the match.  As far as the longer term goals, see how the house purchase goes. Life has a way of sending you two kids and forcing you to tighten the budget. You may have other ideas in three years. (I have no P2P lending experience, by the way.)  Last - many advise that separate finances are a bad path for a couple. It depends. Jane and I have separate check books, and every paycheck just keep enough to write small checks without worry, most of the money goes to the house account. Whatever works for you is what you should do. We've been happily married for most of the 17 years we've been married." "&gt; Lol. Americas are two continents. How many times do I have to educate you?   No, you said America is continents. You are just being weirdly semantic and also failing to distinguish between North and South America. They are not both collectively called America. Nobody groups 2 continents together like that. It's like trying to group Europe and Africa together.  There is nobody who says this. You cannot ""educate"" me on this because literally zero people aside from you think this way.   &gt;Beside that you still have not presented any data. All your points have been invalidated and best you can do is change topics over and over.  What data would you like? America being increasingly protectionist and the stock market being at an all time high?   https://www.cnbc.com/2017/07/26/us-stocks-boeing-earnings-fed.html  I already used your own data against you so in a way that is me using data and you've presented none.  &gt;Still could not address my points about Argentina, Canada, US and etc.  What point? I said Canada was protectionist and Canada is in the top to protectionist countries in the list *you provided.* We have a heavy investment in our own companies, a lot of my tax dollars go to that in fact. Canada is one of the most protectionist countries on the planet. Against my wishes, by the way, but it is the way it is.  &gt;Btw love your fake data and facts. I guess that's how you get cucked so hard to begin with  Cucked? By what? My own facts? What? You sound retarded right now.  &gt;LOL. Chart says tarrif of 10 big countries. Not 10 highest Tarrif. LOLOLOL.  Okay so provide a graph that shows the 10 highest tariffs.  You know what this weird edit of yours tells me?   **YOU DID NOT EVEN LOOK AT YOUR OWN LINK WHEN YOU SENT IT.**   You are just reading it now. So which one is it? Either the graph proves me right or it proves nothing at all. Either way, you fucked up. This is really, really funny.  &gt;Best to stay in your safe space and keep getting cucked.  Ugh, you don't see how embarrassing you sound, do you? Why would someone be cucked in a safe space? Are you saying *this* is a safe space? This sub is very clearly anti-Trump. You don't know what these words or phrases mean.  &gt;I wasn't being homophobic. I called you for what you are. That's your choice. No shame. Keep doing what you do and be Putins holster  Why do you think about cocksucking so much?" "First, you are not exactly ""giving"" the brokerage $2000. That money is the margin requirement to protect them in the case the stock price rises. If you short 200 shares as in your example and they are holding $6000 from you then they are protected in the event of the stock price increasing to $30/share. Sometime before it gets there the brokerage will require you to deposit more money or they will cover your position by repurchasing the shares for your account. The way you make money on the short sale is if the stock price declines. It is a buy low sell high idea but in reverse. If you believe that prices are going to drop then you could sell now when it is high and buy back later when it is lower. In your example, you are selling 200 shares at $20 and later, buying those at $19. Thus, your profit is $200, not counting any interest or fees you have paid. It's a bit confusing because you are selling something you'll buy in the future. Selling short is usually considered quite risky as your gain is limited to the amount that you sold at initially (if I sell at $20/share the most I can make is if the stock declines to $0).  Your potential to lose is unlimited in theory. There is no limit to how high the stock could go in theory so I could end up buying it back at an infinitely high price. Neither of these extremes are likely but they do show the limits of your potential gain and loss.  I used $20/share for simplicity assuming you are shorting with a market order vs a limit order. If you are shorting it would be better for you to sell at 20 instead of 19 anyway. If someone says I would like to give you $20 for that item you are selling you aren't likely to tell them ""no, I'd really only like $19 for it""" Owning a stock via a fund and selling it short simultaneously should have the same net financial effect as not owning the stock.  This should work both for your personal finances as well as the impact of (not) owning the shares has on the stock's price. To use an extreme example, suppose there are 4 million outstanding shares of Evil Oil Company.  Suppose a group of concerned index fund investors owns 25% of the stock and sells short the same amount.   They've borrowed someone else's 25% of the company and sold it to a third party.  It should have the same effect as selling their own shares of the company, which they can't otherwise do.  Now when 25% of the company's stock becomes available for purchase at market price, what happens to the stock?  It falls, of course.   Regarding how it affects your own finances, suppose the stock price rises and the investors have to return the shares to the lender.  They buy 1 million shares at market price, pushing the stock price up, give them back, and then sell another million shares short, subsequently pushing the stock price back down. If enough people do this to effect the share price of a stock or asset class, the managers at the companies might be forced into behaving in a way that satisfies the investors.  In your case, perhaps the company could issue a press release and fire the employee that tried to extort money from your wife's estate in order to win your investment business back.  Okay, well maybe that's a stretch. When you buy a stock, the worst case scenario is that it drops to 0.  Therefore, the most you can lose when buying a stock is 100% of your investment. When you short a stock, however, there's no limit on how high the stock can go.  If you short a stock at 10, and it goes up to 30, then you've lost 200% on your investment.  Therefore shorting stocks is riskier than buying stocks, since you can lose more than 100% of your investment when shorting. because the price might go up, but it will never be as big of a change as a regular price drop i suppose... That is not true.  Stocks can sometimes go up significantly (50-100% or more) in a very short amount of time on a positive news release (such as an earnings or a buyout announcement).  A famous example occurred in 2008, when Volkswagen stock quintupled (went up 400%) in less than 2 days on some corporate news: Porsche, for some reason, wants to control Volkswagen, and by building up its stake has driven up the price. Hedge funds, figuring the share price would fall as soon as Porsche got control and stopped buying, sold a lot of VW shares short. Then last weekend, Porsche disclosed that it owned 42.6 percent of the stock and had acquired options for another 31.5 percent. It said it wanted to go to 75 percent. The result: instant short-squeeze. The German state of Lower Saxony owns a 20 percent stake in VW, which it said it would not sell. That left precious few shares available for anyone else. The shorts scrambled to cover, and the price leaped from about €200, or about $265, to above €1,000. "It is true, as farnsy noted, that you generally do not know when stock that you're holding has been loaned by your broker to someone for a short sale, that you generally consent to that when you sign up somewhere in the small print, and that the person who borrows has to make repay and dividends. The broker is on the hook to make sure that your stock is available for you to sell when you want, so there's limited risk there. There are some risks to having your stock loaned though.  The main one is that you don't actually get the dividend.  Formally, you get a ""Substitute Payment in Lieu of Dividends.""  The payment in lieu will be taxed differently.  Whereas qualified dividends get reported on Form 1099-DIV and get special tax treatment, substitute payments get reported on Form 1099-MISC. (Box 8 is just for this purpose.)  Substitute payments get taxed as regular income, not at the preferred rate for dividends. The broker may or may not give you additional money beyond the dividend to compensate you for the extra tax. Whether or not this tax difference matters, depends on how much you're getting in dividends, your tax bracket, and to some extent your general perspective. If you want to vote your shares and exercise your ownership rights, then there are also some risks.  The company only issues ballots for the number of shares issued by them.  On the broker's books, however, the short sale may result in more long positions than there are total shares of stock. Financially the ""extra"" longs are offset by shorts, but for voting this does not balance. (I'm unclear how this is resolved - I've read that the the brokers essentially depend on shareholder apathy, but I'd guess there's more to it than that.) If you want to prevent your broker from loaning out your shares, you have some options:" When you want to short a stock, you are trying to sell shares (that you are borrowing from your broker), therefore you need buyers for the shares you are selling.  The ask prices represent people who are trying to sell shares, and the bid prices represent people who are trying to buy shares. Using your example, you could put in a limit order to short (sell) 1000 shares at $3.01, meaning that your order would become the ask price at $3.01.  There is an ask price ahead of you for 500 shares at $3.00.  So people would have to buy those 500 shares at $3.00 before anyone could buy your 1000 shares at $3.01. But it's possible that your order to sell 1000 shares at $3.01 never gets filled, if the buyers don't buy all the shares ahead of you.  The price could drop to $1.00 without hitting $3.01 and you will have missed out on the trade. If you really wanted to short 1000 shares, you could use a market order.  Let's say there's a bid for 750 shares at $2.50, and another bid for 250 shares at $2.49.  If you entered a market order to sell 1000 shares, your order would get filled at the best bid prices, so first you would sell 750 shares at $2.50 and then you would sell 250 shares at $2.49. I was just using your example to explain things.  In reality there won't be such a wide spread between the bid and ask prices.  A stock might have a bid price of $10.50 and an ask price of $10.51, so there would only be a 1 cent difference between putting in a limit order to sell 1000 shares at $10.51 and just using a market order to sell 1000 shares and getting them filled at $10.50. Also, your example probably wouldn't work in real life, because brokers typically don't allow people to short stocks that are trading under $5 per share. As for your question about how often you are unable to make a short sale, it can sometimes happen with stocks that are heavily shorted and your broker may not be able to find any more shares to borrow. Also remember that you can only short stocks with a margin account, you cannot short stocks with a cash account. Who's to say it wasn't priced into the markets, at least to some degree? Without any information on the behaviour of holders pre-expiry, no one can know if they've been shorting the stock in advance of selling on expiry day. And with the float being such a small proportion of the total issuance, there's always the risk of sudden fluctuations picking up big momentum - which could easily explain the 7% drop on expiry day. Add into all this uncertainty, the usual risks of shorting (e.g. limited upside, unlimited downside), and the observed phenomena aren't by any means killer blows of the Efficient Market Hypothesis. That's not to say that such evidence doesn't necessarily exist - just that this isn't it.
