US Dollar Index: a) where are long term charts;  also b) is it available on Google Finance by any chance?
a) the quick answer to your correlation is quantitative easing. basically the central bank has been devaluing the US dollar, making the prices of all goods increase (including stocks.)  the stock market appear to have recovered from 2009 lows but its mainly an illusion. anyway the QE packages are very known when the correlation is not there, that means other meaningful things are happening such as better corporate earnings and real growth. b) the thinkorswim platform has charts for dollar futures, symbol /dx
"Most markets around the world have been downtrending for the last 6 to 10 months. The definition of a downtrend is lower lows and lower highs, and until you get a higher low and confirmation with a higher high the downtrend will continue. If you look at the weekly charts of most indexes you can determine the longer term trend. If you are more concerned with the medium term trend then you could look at the daily charts. So if your objective is to try and buy individual stocks and try to make some medium to short term profits from them I would start by first looking at the daily charts of the index your stock belongs to. Only buy when the intermediate trend of the market is moving up (higher highs and higher lows).  You can do some brief analysis on the stocks your interested in buying, and two things I would add to the short list in your question would be to check if earnings are increasing year after year. The second thing to look at would be to check if the earnings yield is greater than the dividend yield, that way you know that dividends are being paid out from current earnings and not from previous earning or from borrowings. You could then check the daily charts of these individual stocks and make sure they are uptrending also. Buy uptrending stocks in an uptrending market. Before you buy anything write up a trading plan and develop your trading rules. For example if price breaks through the resistance line of a previous high you will buy at the open of the next day. Have your money management and risk management rules in place and stick to your plan. You can also do some backtesting or paper trading to check the validity of your strategy. A good book to read on money and risk management is - ""Trade your way to Financial Freedom"" by Van Tharp. Your aim should not be to get a winner on every trade but to let your winners run and keep your losses small." A lot of people here talk about shorting stocks, buying options, and messing around with leveraged ETFs. While these are excellent tools, that offer novel opportunities for the sophisticated investor, Don't mess around with these until you have been in the game for a few years. Even if you can make money consistently right out of the gate, don't do it. Why? Making money isn't your challenge, NOT LOSING money is your challenge. It's hard to measure the scope of the risk you are assuming with these strategies, much less manage it when things head south. So even if you've gotten lucky enough to have figured  out how to make money, you surely haven't learned out how to hold on to it. I am certain that every beginner still hasn't figured out how to comprehend risk and manage losing positions. It's one of those things you only figure out after dealing with it. Stocks (with little to no margin) are a great place to learn how to lose because your risk of losing everything is drastically lower than with the aforementioned tools of the sophisticated investor. Despite what others may say you can make out really well just trading stocks.  That being said, one of my favorite beginner strategies is buying stocks that dip for reasons that don't fundamentally affect the company's ability to make money in the mid term (2 quarters).  Wallstreet loves these plays because it shakes out amateur investors (release bad news, push the stock down shorting it or selling your position, amateurs sell, which you buy at a discount to the 'fair price'.) A good example is Netflix back in 2007. There was a lawsuit because netflix was throttling movie deliveries to high traffic consumers. The stock dropped a good chunk overnight.  A more recent example is petrobras after their huge bond sale and subsequent corruption scandal. A lot of people questioned Petrobras' long-term ability to maintain sufficient liquidity to pay back the loans, but the cashflow and long term projections are more than solid. A year later the stock was pushed further down because a lot of amateur Brazilians invest in Petrobras and they sold while the stock was artificially depressed due to a string of corruption scandals and poor, though temporary, economic conditions. One of my favorite plays back in 2008-2011 was First Solar on the run-up to earnings calls. Analysts would always come out of these meetings downgrading the stock and the forums were full of pikers and pumpers claiming heavy put positions. The stock would go down considerably, but would always pop around earnings. I've made huge returns on this move. Those were the good ole days. Start off just googling financial news and blogs and look for lawsuits and/or scandals. Manufacturing defects or recalls. Starting looking for companies that react predictably to certain events. Plot those events on your chart. If you don't know how to back-test events, learn it.  Google Finance had a tool for that back in the day that was rudimentary but helpful for those starting out. Eventually though, moreso than learning any particular strategy, you should learn these three skills: 1) Tooling: to gather, manipulate, and visualize data on your own.  These days automated trading also seems to be ever more important, even for the small fish. 2) Analytical Thinking learn to spot patterns of the three types:  event based (lawsuits, arbitrage, earnings etc), technical (emas, price action, sup/res), or business-oriented (accounting, strategy, marketing). Don't just listen to what someone else says you should do at any particular moment, critical thinking is essential. 3) Emotions and Attitude: learn how to comprehend risk and manage your trigger finger. Your emotions are like a blade that you must sharpen every day if you want to stay in the game. Disclaimer: I stopped using this strategy in 2011, and moved to a pure technical trading regime. I've been out totally out of the game since 2015. You're being too hard on yourself. You've managed to save quite a bit, which is more than most people ever do. You're in a wonderful position, actually -- you have savings and time! You don't mention how long you want/need to continue working, but I'll assume 20 years or so? You don't have to invest it all at once. Like Pete B says, index funds (just read what Mr. Buffett said in recent news: he'd tell his widow to invest in the S&P 500 Index and not Berkshire Hathaway!) should be a decent percentage. You can also pick a target fund from any of the major investment firms (fees are higher than an Index, but it will take care of any asset allocation decisions). Put some in each. Also look at retirement accounts to take advantage of tax-deferred or tax-free growth, but that's another question and country-specific. In any case, don't even blink when the market goes down. And it will go down. If you're still working, earning, and saving, it'll just be another opportunity to buy more at lower prices. As for the house, no reason you can't invest and save for a house. Invest some for the long term and set aside the rest for the house in 1-5 years. If you don't think you'll ever really buy the house, though, invest the majority of it for the long-term: I have a feeling from the tone of your question that you tend to put off the big financial decisions. So if you won't really buy the house, just admit it to yourself now! "You have a few correlated questions here:  Yes you can. There are only a few investment strategies that require a minimum contribution and those aren't ones that would get a blanket recommendation anyway. Investing in bonds or stocks is perfectly possible with limited funds. You're never too young to start. The power of interest means that the more time you give your money to grow, the larger your eventual gains will be (provided your investment is beating inflation). If your financial situation allows it, it makes sense to invest money you don't need immediately, which brings us to: This is the one you have to look at most. You're young but have a nice chunk of cash in a savings account. That money won't grow much and you could be losing purchasing power to inflation but on the other hand that money also isn't at risk. While there are dozens of investment options1 the two main ones to look at are: bonds: these are fixed income, which means they're fairly safe, but the downside is that you need to lock up your money for a long time to get a better interest rate than a savings account index funds that track the market: these are basically another form of stock where each share represents fractions of shares of other companies that are tracked on an index such as the S&P 500 or Nasdaq. These are much riskier and more volatile, which is why you should look at this as a long-term investment as well because given enough time these are expected to trend upwards. Look into index funds further to understand why. But this isn't so much about what you should invest in, but more about the fact that an investment, almost by definition, means putting money away for a long period of time. So the real question remains: how much can you afford to put away? For that you need to look at your individual situation and your plans for the future. Do you need that money to pay for expenses in the coming years? Do you want to save it up for college? Do you want to invest and leave it untouched to inspire you to keep saving? Do you want to save for retirement? (I'm not sure if you can start saving via IRAs and the like at your age but it's worth looking into.) Or do you want to spend it on a dream holiday or a car? There are arguments to be made for every one of those.  Most people will tell you to keep such a ""low"" sum in a savings account as an emergency fund but that also depends on whether you have a safety net (i.e. parents) and how reliable they are. Most people will also tell you that your long-term money should be in the stock market in the form of a balanced portfolio of index funds. But I won't tell you what to do since you need to look at your own options and decide for yourself what makes sense for you. You're off to a great start if you're thinking about this at your age and I'd encourage you to take that interest further and look into educating yourself on the investments options and funds that are available to you and decide on a financial plan. Involving your parents in that is sensible, not in the least because your post-high school plans will be the most important variable in said plan. To recap my first point and answer your main question, if you've decided that you want to invest and you've established a specific budget, the size of that investment budget should not factor into what you invest it in. 1 - For the record: penny stocks are not an investment. They're an expensive form of gambling." It looks like GOOG did not have a pre-market trade until 7:14 am ET, so Google Finance was still reporting the last trade it had, which was in the after-hours session yesterday. FB, on the other hand, was trading like crazy after-hours yesterday and pre-market today as it had an earnings report yesterday. The portion of a stock movement not correlated with stocks in general is called Alpha. I don't know of any online tools to graph alpha. Keep in mind that a company like Apple is so huge right now that any properly weighted index will have to correlate with it to some degree. I still can't understand why there is a price discrepancancy.  There isn't. It's the same stock and price differences between such major exchanges will always be minimal. I think you simply haven't paid attention to the date range. It seems Google finance only has data for FRA:BMW reaching back to 2011, so if you try to look at the development of your investment since 2009, you're not getting comparable data. What really matters is of course how it compares to future prices. Are we making the assumption that the future prices will be more like the average over the last 100 years (which, by looking at your diagram, we seem to be one standard deviation or so above)?
