Stocks that only have 1 really high peak
"Investing is not the same as illegal drugs.  One does not start with pot and progress to things like heroin in order to get a better high.  Penny stocks are a fools game and not an entry into the world of investing. The charts you mentioned are fake and likely the result of pump and dump schemes as my colleagues have pointed out in the comments.  They have no bearing on investing.  Good investment grade companies have many peaks and valleys over time.  Look at any company you are familiar with Apple, Google, Tesla, GE, Microsoft, etc... One has a few choices in getting ""into investing"" to name a few: All of those are valid and worthy pursuits.  Read books by Jack Bogle."
You should definately have a stop loss in place to manage your risk. For a time frame of 5 to 10 years I would be looking at a trailing stop loss of 20% to 25% off the recent high.  Another type of stop you could use is a volatility stop. Here the more volatile the stock the larger the stop whilst the less volatile the stock the smaller the stop. You could use 3 or 4 x Weekly ATR (Average True Range) to achieve this. The reason you should always use a stop loss is because of what can happen and what did happen in 2008. Some stock markets have yet to fully recover from their peaks at the end of 2007, almost 9 years later. What would you do if you were planning to hold your positions for 5 years and then withdrawal your funds at the end of June 2021 for a particular purpose, and suddenly in February 2021 the market starts to fall. By the time June comes the market has fallen by over 50%, and you don't have enough funds available for the purpose you planned for. Instead if you were using a trailing stop loss you would manage to keep at least 75% of the peak of your portfolio. You could even spend 10 minutes each week to monitor your portfolio for warning signs that a downtrend may be around the corner and adjust your trailing stop to maybe 10% in these situations, protecting 90% of the peak of your portfolio. If the downtrend does not eventuate you can adjust your trailing back to a higher percentage. If you do get stopped out and shortly after the market recovers, then you can always buy back in or look for other stocks and ETFs to replace them. Sure you might lose a bit of profits if this happens, but it should always be part of your investment plan and risk management how you will handle these situation. If you are not using stop losses, risk management and money management you are essentially gambling. If you say I am going to buy these stocks and ETFs hold them for 10 years and then sell them, then you are just hoping to make gains - which is essentially gambling. "In general, there should be a ""liquidity premium"" which means that less-liquid stocks should be cheaper. That's because to buy such a stock, you should demand a higher rate of return to compensate for the liquidity risk (the possibility that you won't be able to sell easily). Lower initial price = higher eventual rate of return. That's what's meant when Investopedia says the security would be cheaper (on average). Is liquidity good? It depends. Here's what illiquidity is. Imagine you own a rare piece of art. Say there are 10 people in the world who collect this type of art, and would appreciate what you own. That's an illiquid asset, because when you want to sell, maybe those 10 people aren't buying - maybe they don't want your particular piece, or they all happen to be short on funds. Or maybe worse, only one of them is buying, so they have all the negotiating leverage. You'll have to lower your price if you're really in a hurry to sell. Maybe if you lower your price enough, you can get one of the 10 buyers interested, even if none were initially. An illiquid asset is bad for sellers. Illiquid means there aren't enough buyers for you to get a bidding war going at the time of your choosing. You'll potentially have to wait around for buyers to turn up, or for a stock, maybe you'd have to sell a little bit at a time as buyers want the shares. Illiquid can be bad for buyers, too, if the buyer is for some reason in a hurry; maybe nobody is selling at any given time. But, usually buyers don't have to be in a hurry. An exception may be if you short sell something illiquid (brokers often won't let you do this, btw). In that case you could be a forced buyer and this could be very bad on an illiquid security. If there are only one or two sellers out there, they now have the negotiating leverage and they can ask whatever price they want. Illiquidity is very bad when mixed with margin or short sales because of the potential for forced trades at inopportune times. There are plenty of obscure penny stocks where there might be only one or two trades per day, or fewer. The spread is going to be high on these because the bids at a given time will just be lowball offers from buyers who aren't really all that interested, unless you want to give your stock away, in which case they'll take it. And the asks are going to be from sellers who want to get a decent price, but maybe there aren't really any buyers willing to pay, so the ask is just sitting there with no takers. The bids and asks may be limit orders that have been sitting open for 3 weeks and forgotten about. Contrast with a liquid asset. For example, a popular-model used car in good condition would be a lot more liquid than a rare piece of art, though not nearly as liquid as most stocks. You can probably find several people that want to buy it living nearby, and you're not going to have to drop the price to get a buyer to show up. You might even get those buyers in a bidding war. From illiquid penny stocks, there's a continuum all the way up to the most heavily-traded stocks such as those in the S&P500. With these at a given moment there will be thousands of buyers and sellers, so the spread is going to close down to nearly zero. If you think about it, just statistically, if there are thousands of bids and thousands of asks, then the closest bid-ask pair is going to be close together. That's a narrow spread. While if there are 3 bids and 2 asks on some illiquid penny stock, they might be dollars away from each other, and the number of shares desired might not match up. You can see how liquidity is good in some situations and not in others. An illiquid asset gives you more opportunity to get a good deal because there aren't a lot of other buyers and sellers around and there's some opportunity to ""negotiate"" within the wide spread. For some assets maybe you can literally negotiate by talking to the other party, though obviously not when trading stocks on an exchange. But an illiquid asset also means you might get a bad deal, especially if you need to sell quickly and the only buyers around are making lowball offers. So the time to buy illiquid assets is when you can take your time on both buying and selling, and will have no reason for a forced trade on a particular timeline. This usually means no debt is involved, since creditors (including your margin broker) can force you to trade. It also means you don't need to spend the money anytime soon, since if you suddenly needed the money you'd have a forced trade on your hands. If you have the time, then you put a price out there that's very good for you, and you wait for someone to show up and give you that price - this is how you get a good deal. One more note, another use of the term liquid is to refer to assets with low or zero volatility, such as money market funds. An asset with a lot of volatility around its intrinsic or true value is effectively illiquid even if there's high trade volume, in that any given point in time might not be a good time to sell, because the price isn't at the right level. Anyway, the general definition of a liquid investment is one that you'd be comfortable cashing out of at a moment's notice. In this sense, most stocks are not all that liquid, despite high trading volume. In different contexts people may use ""liquid"" in this sense or to mean a low bid-ask spread." 1.

Rather, preferred shareholders are normally in line ahead (i.e. in preference to or ""preferred"") of common shareholders in terms of dividend payment.  This is an extremely important distinction, because unlike investments that we generally consider ""guaranteed"" such as CDs (known as GICs in Canada), a company's board can suspend the dividend at anytime for long periods of time without significant repercussions -- whereas a missed payment to a bank or secured bondholder can often push a company into bankruptcy very quickly. 2) Due to point 1), it is extremely important to know the ""convenants"" or rules sorrounding both the preferred shares you are buying and the other more senior creditors of that issuing company (i.e. taxes (almost always come first), banks loans, leases, bonds etc.).  It is also important to know if a particular preferred share has ""cumulative"" dividends.  You generally only want to buy preferred's that have ""cumulative"" dividends, since that means that anytime the company misses a payment, they must pay those dividends first before any other dividends at the same or lower priority in the future. 3) Unlike a common stock, your upside on a preferred stock is relatively fixed: you get a fixed share of the company's profit and that's it, whereas a common shareholder gets everything that's left over after interest and preferred dividends are paid. So if the company does really well you will theoretically do much better with common stock over time. For the above reasons, it is generally advisable to think of preferred shares as being more similar to really risky bonds in the same company, rather than similar to common stock.   Of course, if you are an advanced investor there are a lot more variables in play such as tax considerations and whether the preferred have special options attached to them such conversion into common shares." Would you also suggest some stock with interesting returns and risks? Because i tried with FB, GS, JNJ, MCD, F and the have low returns in the last 5 years, so when you compare them to commodities you don't see so much difference in stdev and returns. Willis Group Holdings Set to Join the S&P 500; Fossil Group to Join S&P MidCap 400; Adeptus Health to Join S&P SmallCap 600 notes in part for the S & P case: Willis Group Holdings plc (NYSE:WSH) will replace Fossil Group Inc.   (NASD:FOSL) in the S&P 500, and Fossil Group will replace Towers   Watson & Co. (NASD:TW) in the S&P MidCap 400 after the close of   trading on Monday, January 4. Willis Group is merging with Towers   Watson in a deal expected to be completed on or about that date   pending final conditions. Post merger, Willis Group Holdings will   change its name to Willis Towers Watson plc and trade under the ticker   symbol “WLTW”. Fossil has a market capitalization that is more   representative of the midcap market space. As of Jan. 8, Fossil is about $1.44B in market cap and Willis is $21.02B for those wondering. Apple with a market cap of $540.58B is 3.26% of the index making the entire index worth approximately $16,582.21B, so Fossil is worth .00868% of the overall index for those wanting some numbers here. Thus, if a company acquires another and becomes bigger than there can be replacements made in those indices that have an artificial number of small members. Alternatively, a member may be removed for lack of representation where it is just so small compared to other companies that may be a better fit as some indices could be viewed as actively managed in a sense. In contrast, there are indices like those from Russell, known for the Russell 2000 small-cap index: Q: Why don't you reconstitute the indexes more often than once a year? A: Maintaining representative indexes must be weighed against the   costs associated with making frequent changes to index constituents   (namely, buying and selling stocks). The Russell Indexes are annually reconstituted because our research   has shown that this strikes a reasonable balance between accuracy and   cost. We originally reconstituted our indexes quarterly, then   semi-annually, but found these options to be suboptimal. Our extensive   research demonstrates that annual reconstitution accurately represents   the capitalization segments and minimizes the turnover required to   reflect the segments as they change. Thus there can be different scenarios.  Then there can be the effect on index funds when price-weighted indices like the Dow Jones Industrial Average has a member that does a stock split that causes some rebalancing too. On the DJIA Divisor: The Dow Jones Industrial Average (DJIA) is a price-weighted index that   is calculated by dividing the sum of the prices of the 30 component   stocks (Dow Jones Industrial Average components) by a number called   the DJIA Divisor or Dow Divisor . The index divisor is updated   periodically and adjusted to offset the effect of stock splits, bonus   issues or any change in the component stocks included in the DJIA.   This is done in order to keep the index value consistent. There is some convergence, but the chart seems to indicate that 5 star funds end up on the upper end of average (3 stars) whereas 1 star funds end up on the lower end of average (1.9 stars) over the long term. I would have thought that the stars would be completely useless as forward looking indicators, but they seem to have been slightly useful? Nothing is guaranteed - candlesticks are not crystal balls nor is any part of technical analysis. Candlestick patterns used correctly and in combination with other western technical indicators can increase the probability of a trade going into the derived direction, but they are not a guarantee - which is why you should always use stop losses with your candlestick or any trading. In saying that, another candlestick pattern that can provide high probability trades is the Doji, or a combination of Dojis in a row at a market extreme. Note that both Engulfing patterns and Dojis work best at price extremes (highs and lows) and in combination with other technical indicators such as an overbought momentum indicator at a market high, or an oversold momentum indicator at a market low. EDIT - An Example Here is a sample trade I placed on the 17th October and am currently 15.6% in profit on. See the chart below as it shows taking the trade on the open of the following day after a bullish engulfing pattern appeared at the bottom of a downtrend on the 16th in combination with the Slow Stochastic crossing over in the oversold region (below 20%). I would consider this a high probability trade and have placed an initial stop loss at 10% below my open price in case the trade went against me. As the price moved up I moved the 10% stop loss up as a trailing stop loss. My profit target is set at 25% or $4.00.
