Deal with stock PSEC
It looks like it has to deal with an expiration of rights as a taxable event. I found this link via google, which states that  Not only does the PSEC shareholder have a TAXABLE EVENT, but he has   TWO taxable events. The net effect of these two taxable events has   DIFFERENT CONSEQUENCES for DIFFERENT SHAREHOLDERS depending upon their   peculiar TAX SITUATIONS. The CORRECT STATEMENT of the tax treatment of unexercised PYLDR rights   is in the N-2 on page 32, which reads in relevant part as follows: “…, if you receive a Subscription Right from PSEC and do not sell or   exercise that right before it expires, you should generally expect to   have (1) taxable dividend income equal to the fair market value (if   any) of the Subscription Right on the date of its distribution by PSEC   to the extent of PSEC’s current and accumulated earnings and profits   and (2) a capital loss upon the expiration of such right in an amount   equal to your adjusted tax basis (if any) in such right (which should   generally equal the fair market value (if any) of the Subscription   Right on the date of its distribution by PSEC).” Please note, for quarterly “estimated taxes” purposes, that the   DIVIDEND taxable events occur “ON THE DATE OF ITS DISTRIBUTION BY PSEC   (my emphasis),” while the CAPITAL LOSS occurs “UPON EXPIRATION OF SUCH   RIGHT” (my emphasis). They do NOT occur on 31 December 2015 or some   other date. However, to my knowledge, neither of the taxable events he mentions would be taxed by 4/15. If you are worried about it, I would recommend seeing a tax professional. Otherwise I'd wait to see the tax forms sent by your brokerage.
generally Forward P/E is computed as current price / forward earnings.  The rationale behind this is that buying the stock costs you the current price, and it gives you a claim on the future earnings. "What you need to do is go to yahoo finance and look at different stock's P/E ratios. You'll quickly see that the stocks can be sorted by this number. It would be an interesting exercise to get an idea of why P/E isn't a fixed number, how certain industries cluster around a certain number, but even this isn't precise. But, it will give you an idea as to why your question has no answer. ""Annual earnings are $1. What is the share price?"" ""Question has no answer""" Try to find the P/E ratio of the Company and then Multiply it with last E.P.S, this calculation gives the Fundamental Value of the share, anything higher than this Value is not acceptable and Vice versa. It doesn't matter which exchange a share was purchased through (or if it was even purchased on an exchange at all--physical share certificates can be bought and sold outside of any exchange). A share is a share, and any share available for purchase in New York is available to be purchased in London. Buying all of a company's stock is not something that can generally be done through the stock market. The practical way to accomplish buying a company out is to purchase a controlling interest, or enough shares to have enough votes to bind the board to a specific course of action. Then vote to sell all outstanding shares to another company at a particular fixed price per share. Market capitalization is an inaccurate measure of the size of a company in the first place, but if you want to quantify it, you can take the number of outstanding shares (anywhere and everywhere) and multiply them by the price on any of the exchanges that sell it. That will give you the market capitalization in the currency that is used by whatever exchange you chose. Tell your broker.  You can usually opt to have certain positions be FIFO and others LIFO.  Definitely possible with Interactive Brokers. "I believe that your option contracts will become ""non-standard"" and will be for a combination of ACE stock and cash.  The allocation between stock and cash should follow that of the acquisition parameters of the underlying - probably with fractional shares converted to cash. Hence 1 call contract for 100 shares of CB will become 1 call contract for 60 shares of ACE + $6293 cash + a cash correction for the 0.19 fractional share of ACE that you would have had claim to get.  The corrections should be 0.19 sh x $62.93/sh." If the share is listed on a stock exchange that creates liquidity and orderly sales with specialist market makers, such as the NYSE, there will always be a counterparty to trade with, though they will let the price rise or fall to meet other open interest.  On other exchanges, or in closely held or private equity scenarios, this is not necessarily the case (NASDAQ has market maker firms that maintain the bid-ask spread and can do the same thing with their own inventory as the specialists, but are not required to by the brokerage rules as the NYSE brokers are).  The NYSE has listing requirements of at least 1.1 million shares, so there will not be a case with only 100 shares on this exchange.

It supports both fundamental and technical analysis. "From some of your previous questions it seems like you trade quite often, so I am assuming you are not a ""Buy and Hold"" person. If that is the case, then have you got a written Trading Plan? Considering you don't know what to do after a 40% drop, I assume the answer to this is that you don't have a Trading Plan. Before you enter any trade you should have your exit point for that trade pre-determined, and this should be included in your Trading Plan. You should also include how you pick the shares you buy, do you use fundamental analysis, technical analysis, a combination of the two, a dart board or some kind of advisory service? Then finally and most importantly you should have your position sizing and risk management incorporated into your Plan. If you are doing all this, and had automatic stop loss orders placed when you entered your buy orders, then you would have been out of the stock well before your loss got to 40%. If you are looking to hang on and hoping for the stock to recover, remember with a 40% drop, the stock will now need to rise by 67% just for you to break even on the trade. Even if the stock did recover, how long would it take? There is the potential for opportunity loss waiting for this stock to recover, and that might take years. If the stock has fallen by 40% in a short time it is most likely that it will continue to fall in the short term, and if it falls to 50%, then the recovery would need to be 100% just for you to break even. Leave your emotions out of your trading as much as possible, have a written Trading Plan which incorporates your risk management. A good book to read on the psychology of the markets, position sizing and risk management is ""Trade your way to Financial Freedom"" by Van Tharp (I actually went to see him talk tonight in Sydney, all the way over from the USA)." "If I buy the one from NSY, is it the ""real"" Sinopec? No - you are buying an American Depository Receipt. Essentially some American bank or other entity holds a bunch of Sinopec stock and issues certificates to the American exchange that American investors can trade.  This insulates the American investors from the cost of international transactions.   The price of these ADRs should mimic the price of the underlying stock (including changes the currency exchange rate) otherwise an arbitrage opportunity would exist.  Other than that, the main difference between holding the ADR and the actual stock is that ADRs do not have voting rights. So if that is not important to you then for all intents and purposes trading the ADR would be the same as trading the underlying stock." you can try CME DataSuite.

Are the assets easily liquidated to get that value or could there be trouble getting the fair market value as some assets may not be as easy to sell as you may think. The Motley Fool a few weeks ago noted a book value of $10 per share. I could wonder what is behind that which could be mispriced as some things may have fallen in value that aren't in updated financials yet. Another point from that link: After suffering through the last few months of constant cries from   naysayers about the company’s impending bankruptcy, shareholders of   Penn West Petroleum Ltd. (TSX:PWT)(NYSE:PWE) can finally look toward   the future with a little optimism. Thus, I'd be inclined to double check what is on the company books. I am not required to hold any company stock. I also have an ESOP plan carrying a similar number of shares in company stock.  So if it were to be sold, what would the recommendation be to replace it? I can move the shares into any option shown, and have quite a few others.  Not dealing with any huge amounts, just a 4.5% contribution over three years (so far).
