Stock Investing: Martingale Strategy or Dollar-Cost-Averaging?

To some people, stock investing is just like gambling. Buy low, sell high. However, it is almost impossible to predict the market.

Fortunately, if we assume that no matter how much does the stock price falls, it will always increase ‘someday’, martingale strategy can also help you to guarantee profits.

Based on the illustration below, supposed we start to buy 1 unit of stock at the price of 10, if the price increases to 11, we sell it and make a profit of 1.

However, if the price falls to 9, we can actually buy another 2 units, such that when the price increase to 10, we sell them and make a profit of 2.

If the price falls again to 8, we buy another 3 units, such that when the price increase to 9, we sell them and make a profit of 3.

And so on…

Practicing this strategy will require you to have sufficient buying power, as well as the correct judgement on the choice of stock. In short, choose one stock that you believe that it will grow someday, and invest within your means. Invest safe.

    Interesting strategy.. perfect in theory.. but very difficult to achieve in practice.. you need to have boatloads of cash on hand to double down and identifying a solid company that will not delist

    " it will always increase ‘someday’ " that make me laugh,hhh. Maybe it went down 5% a day for ten days, and then it went up 1% a day, and then it went down again.

    Let me tell you, don't be fooled by this strategy. When people find that their stock has fallen, they just sell it like ccccrazy and it falls even more.

    It doesn't make sense. What if I buy 2 @9 then it falls to 8? To be CALM and reasonable is important

    🤣🤣wake up ! wake up! wake up! Your situation is suitable only when the stock market is stable, but not when there is a bear.

    But there's something wrong with that. How could I find it will go up soon? It's very likely to keep losing.🤔🤔

    Your strategy looks good, but the truth is difficult. who wants to buy more as it goes down? Wouldn't that be more of a loss?🤣🤣 hhh

    This strategy limits the purchasing power of so many many people.
