Quarterly dividends to monthly dividends
Technically you should take the quarterly dividend yield as a fraction, add one, take the cube root, and subtract one (and then multiple by the stock price, if you want a dollar amount per share rather than a rate).  This is to account for the fact that you could have re-invested the monthly dividends and earned dividends on that reinvestment. However, the difference between this and just dividing by three is going to be negligible over the range of dividend rates that are realistically paid out by ordinary stocks.
Dividends are normally paid in cash, so don't generally affect your portfolio aside from a slight increase to 'cash'.  You get a check for them, or your broker would deposit the funds into a money-market account for you.  There is sometimes an option to re-invest dividends, See Westyfresh's answer regarding Dividend Re-Investment Plans. As Tom Au described, the dividends are set by the board of directors and announced.  Also as he indicated just before the 'record' date, a stock which pays dividends is worth slightly more (reflecting the value of the dividend that will be paid to anyone holding the stock on the record date) and goes down by the dividend amount immediately after that date (since you'd now have to hold the stock till the next record date to get a dividend)  In general unless there's a big change in the landscape (such as in late 2008) most companies pay out about the same dividend each time, and changes to this are sometimes seen by some as 'indicators' of company health and such news can result in movement in the stock price. When you look at a basic quote on a ticker symbol there is usually a line for Div/yeild which gives the amount of dividend paid per share, and the relative yeild (as a percentage of the stock price).  If a company has been paying dividends, this field will have values in it, if a company does not pay a dividend it will be blank or say NA (depending on where you get the quote).  This is the easiest way to see if a company pays a dividend or not.  for example if you look at this quote for Google, you can see it pays no dividend  Now, in terms of telling when and how much of a dividend has been paid, most financial sites have the option when viewing a stock chart to show the dividend payments.  If you expand the chart to show at least a year, you can see when and how much was paid in terms of dividends.  For example you can see from this chart that MSFT pays dividends once a quarter, and used to pay out 13 cents, but recently changed to 16 cents.   if you were to float your mouse over one of those icons it would also give the date the dividend was paid. Here is the definition of Ex-dividend date from the SEC: Once the company sets the record date, the stock exchanges or the National Association of Securities Dealers, Inc. fix the ex-dividend date. The ex-dividend date is normally set for stocks two business days before the record date. If you purchase a stock on its ex-dividend date or after, you will not receive the next dividend payment. Instead, the seller gets the dividend. If you purchase before the ex-dividend date, you get the dividend. The linked document discusses weekend, and holidays involved in the calculation. The difference between the record date and the ex-dividend is to allow for the three days of settlement. Dividends are not paid immediately upon reception from the companies owned by an ETF. In the case of SPY, they have been paid inconsistently but now presumably quarterly. A mutual fund makes distributions of its dividends and capital gains, usually once a year, or seminanually or quarterly or monthly etc; it does not distribute any capital losses to its shareholders but holds them for offsetting capital gains in future years, (cf, this answer of mine to a different question). A stock pays  dividends; a stock neither has nor does it  distribute capital gains: you get capital gains (or losses) when you sell the shares of the stock, but these are not called distributions of any kind. Similarly, you incur capital gains or losses when you  redeem shares of mutual funds but these are not called distributions  either. Note that non-ETF mutual fund shares are generally not bought and sold on stock exchanges; you buy shares directly from the fund and you sell shares back (redeem them) directly to the fund.  All of the above transactions are taxable events for the year to you unless the shares are being held in a tax-deferred account or are tax-free for other reasons (e.g. dividends from a municipal bond fund). I guess you are making quite a bit of assumptions without clarifying what you are trying to achieve. As a non-resident you cannot incorporate a sole proprietorship in Singapore. You have to be citizen. Alternatively you can register a company that has its own norms like minimum number of directors and some being Singapore national, etc. As you are paying dividend and not salary to yourself, the company will be required to pay taxes on gains. So all consulting money is gain as there is no expense. The balance when you transfer to Spain would potentially get taxed as income to you subject to DTAA If markets are efficient (which they aren't, but anyways...), the frequency of DCA investments shouldn't yield any meaningful difference in return.  The one possible item to note is that if you're able to invest more frequently, you'll have more money exposed to the effects of compounding for longer, which *may* increase return. However, there are also transaction costs to consider, which may render something like *continuous* DCA-ing ineffective.   That same compounding effect also negates the potential benefits of DCA altogether, making it more logical to lump sum your investments.   You may be conflating DCA with simply making additional cash every week that's available for investment. If that's the case, again, lump sum as early as possible should yield the best results...  (this isn't financial advice, read the sidebar disclaimers) Rebalancing your portfolio doesn't have to include selling.  You could simply adjust your buying to keep your portfolio in balance.  If you portfolio has shifted from 50% stocks and 50% bonds to 75% stocks and 25% bonds, you can just only use new savings to buy bonds, until you are back at 50-50. Remember to take into account taxes if you are thinking of selling to rebalance in taxable accounts. The goal of rebalancing is to keep your exposures the way that you want them.  Assuming that you had a good reason to have a portfolio of 50% stocks and 50% bonds, you probably want to keep your portfolio similar in the future.  If you end up with a portfolio of 75% stocks and 25% bonds due to stock market fluctuations, the exposure and the risk / return profile of your portfolio will have changed, and it's probably not something that you want. You don't want to rebalance just for the sake of rebalancing either.  There can be costs to rebalancing (taxes, transaction fees, etc...) and these aren't always worth the effort.  That's why you don't need to rebalance every month or if your portfolio has shifted from 50/50 to 51/49. I take a look at my portfolio once a year, and adjust my automated investments so that by the end of the next year I'm back to the ratio I want. "Let me provide a general answer, that might be helpful to others, without addressing those specific stocks. Dividends are simply corporate payouts made to the shareholders of the company.  A company often decides to pay dividends because they have excess cash on hand and choose to return it to shareholders by quarterly payouts instead of stock buy backs or using the money to invest in new projects. I'm not exactly sure what you mean by ""dividend yield traps.""  If a company has declared an dividend for the upcoming quarter they will almost always pay.  There are exceptions, like what happened with BP, but these exceptions are rare.  Just because a company promises to pay a dividend in the approaching quarter does not mean that it will continue to pay a dividend in the future.  If the company continues to pay a dividend in the future, it may be at a (significantly) different amount. Some companies are structured where nearly all of there corporate profits flow through to shareholders via dividends.  These companies may have ""unusually"" high dividends, but this is simply a result of the corporate structure.    Let me provide a quick example: Certain ETFs that track bonds pay a dividend as a way to pass through interest payments from the underlying bonds back to the shareholder of the ETF. There is no company that will continue to pay their dividend at the present rate with 100% certainty.  Even large companies like General Electric slashed its dividend during the most recent financial crisis.  So, to evaluate whether a company will keep paying a dividend you should look at the following: Update: In regards to one the first stock you mentioned, this sentence from the companies of Yahoo! finance explains the ""unusually"" dividend: The company has elected to be treated as a REIT for federal income tax purposes and would not be subject to income tax, if it distributes at least 90% of its REIT taxable income to its share holders."
