How to read a chart after a split?
"The share price on its own has little relevance without looking at variations. In your case, if the stock went from 2.80 to 0.33, you should care only about the 88% drop in value, not what it means in pre-split dollar values. You are correct that you can ""un-split"" to give you an idea of what would have been the dollar value but that should not give you any more information than the variation of 88% would. As for your title question, you should read the chart as if no split occurred as for most intents and purposes it should not affect stock price other than the obvious split."
That is why I love these games.  It is the educational experience without the risk.  It forces me to look at what really powers the market and how fickle it truly is, to learn how to read charts and feel the winds of change, without losing real world money in the name of learning. "Ordinarily a stock split increases all shareholders' share counts, so that there is no change in anybody's voting power.  For example, if you owned 1% of the company before the split, after the split you now have twice as many shares, but there are now twice as many shares outstanding, so you still own 1% of the company.  Also, stock splits are not ordinarily ""triggered"".  Usually they happen when the board decides that for one reason or another it's desirable to increase the number of shares in circulation, which causes the price of each share to decrease proportionally.   I'm not familiar with the show, and in particular I don't know what the action is that the character being addressed is thinking of taking, but it sounds like they are describing something akin to a ""poison pill"".  In these arrangements, the ""pill"" is triggered by some predefined condition, say a party acquiring shares in excess of a defined threshold.  What typically happens is that shareholders other than the ones who triggered the pill get a chance to buy shares at a substantial discount, thereby diluting the shares of the party that triggered it.  Because the other shareholders have to buy their additional shares, albeit at a discount, and because it applies only to certain shares, it's not really a split, but it's close enough that the writers of the show may have felt it was worth using the term that is more familiar to the public." William %R is a momentum indicator used for measuring overbought and oversold levels, it is not used to predict the price of a stock. In fact, William %R, like all momentum indicators, is a lagging indicator - meaning the indicator level changes as the price of the stock changes. It ranges from 0 to -100. Usually when a reading is less than -80 the stock can be considered to be oversold, and when the reading is above -20 the stock can be considered overbought. When viewed together with the price chart, this can help provide a trader with entry and exit points into and out of a trade. The best answer to this question will depend on you and your wife. What is 'fair' for some may not be 'fair' for others. Some couples split expenses 50:50. Some split proportionately based on income. Some pool everything together. What works best for you will depend on your relative incomes, your financial goals, living standards, and most importantly, your personal beliefs. Here is a great question with various viewpoints: How to organize bank accounts with wife. It doesn't touch heavily on home ownership / pre-nuptial agreements, but might be a good starting point to getting you to think about your options. Consider providing another loan to your wife for additional investments in the home. It seems you are both comfortable with the realities of the pre-nuptial agreement; one of those realities seems to be that in the event of divorce you would lose access to the house. Loaning money has the benefit of allowing for the improvements to be done immediately, while clearly delineating what you have spent on the home from what she has spent on the home. However, this may not be 'fair', depending on how you both define the term. Have you discussed how expenses and savings would be split between you? Since there is no mortgage on the house, she has effectively contributed her pre-marital assets towards paying substantially all of your housing costs. It may be 'fair' for you to contribute to housing costs by at least splitting maintenance 50:50, or it may not be. Hopefully you talked about finances before you got married, and if not, now would be the best time to start. I personally would hate to have an 'uneasy' feeling about a relationship because I failed to openly communicate about finances. My broker collates the order book by price and marketplace, displaying the number of shares available at each level, sorted as in Victor's screencap. You can glean information from not just a snapshot of the order book but also by watching how it changes over time. Although it's not always a complete picture -- many brokers hold limit orders internally until the market is close, at which point they'll route to an exchange or trade internally. And of course skilled market participants know that there's people out there looking to glean information from the order book and will act to confuse the picture. The order book can show you: Combined with a list of trades (price & size, and whether it was a buy or sell), you can get a much more complete picture of what's going on with a stock than by looking at charts alone. "First, it's much safer to be shorting stocks over $5 than stocks under $5.  I use 3 indicators to show that a stock has topped out and about to drop. Key is the timing cause the initial drop is often the biggest. More close you get in at the top, the higher the risk. Using 1D Charts ONLY:   - MACD Indicator:  I use the histogram, when it reaches a peak height, and the next day it is down 1 ""Step"". If you wait til the MACD lines cross, you are pretty late IMHO.  Need to get in earlier. Timing is everything.   - RSI(15) - Needs to topped out and above 67 meaning, ""Over bought""  - Do not buy when RSI is high above 70. Often stocks go on a Run up when RSI is over 70!   - I use Stoch RSI or CCI to confirm my status on RSI. I like to see that all 3 indicators agree. This gives me a 75% chance that the stock will drop. It may take a day or 2.. so you need patience." "Company Distribution is attempting to show a histogram of how many companies fall within a given range so you can visualize the number of companies that meet a certain parameter.  For example if you move the ""Market Cap"" sliders so the minimum slider is just before the large rise in the distribution and move the maximum slider so it is just after the fall off in distribution, you can see that most companies have a market cap between ~5700 and ~141B." "Piggybacking on this, the best thing you can do is ask current analysts for help. You're new and people expect you to ask dumb questions at this point. So ask them now while you still get a pass.  With that being said, there's a strategy to it. Before you ever ask a question, spend at least 5 minutes trying to figure out the answer on your own. OP did a Google search, which is great. So many people won't do this. Finally, the way you ask the question is key. I would go to an analyst and say, ""[Boss] asked me to get a list of all US apartment flooring companies. I looked on Google to see if I could find anything there. If you were doing this, where would you go to find the information?""  They'll usually even walk you through how to do it if there's something special with the service you have for the task. You'll also make them feel important. And you'll get the task done fast.  Also, if you run into trouble with the boss after presenting it, you can always back yourself up by saying you asked around the office for what tool to use and people told you to use that. But be strategic with how you say it because you don't want to throw anyone under the bus."
