What happens when you buy a stock and the price goes up?

By this we mean that share prices change because of supply and demand. If more people want to buy a stock (demand) than sell it (supply), then the price moves up. Conversely, if more people wanted to sell a stock than buy it, there would be greater supply than demand, and the price would fall.
Should I buy stock when its going up?
Yes, you should invest when the market is down—and when it’s up and when it’s sideways. If you’re already planning to invest, buying while prices are down can be a smart move. After all, “buy low, sell high” is a standard mantra for successful investors.
Can you lose all your money in stocks?
A drop in price to zero means the investor loses his or her entire investment – a return of -100%. Conversely, a complete loss in a stock’s value is the best possible scenario for an investor holding a short position in the stock. To summarize, yes, a stock can lose its entire value.
What was the stock price in the second month of the month?
The second month, the shares were $21, so that month you got 4.77 shares, netting you a $19 gain, and so forth. In good times, you get fewer shares, which reduces the future potential upside, but it also means you have a nice total gain on your investment. Suppose the share price had dropped from $20 to $15 in that first year.
How much does it cost to buy stock at$ 15?
Since the share price is only $15, you can snap up 6.67 shares per month for as long as the slump lasts. When things brighten up six months later, you have purchased 6 x 6.67 = 40 shares at what might have been the bottom. Then, even with a modest rebound to $18 a share, you have now made a gain of 40 x $3 = $120 from those bargain shares alone.
What happens if you invest$ 100 a month in stocks?
Now you only get four shares for your $100, but you’re happy anyway; the five shares from that first month a year ago have appreciated in value, 5 x $25 = $125, netting a $25 gain. The second month, the shares were $21, so that month you got 4.77 shares, netting you a $19 gain, and so forth.
What’s the loss on a month’s investment in stocks?
You’d have made a loss of 5 x $5 = $25 on your first month’s investment. The second month you bought shares at $19 apiece, meaning you got 5.26 shares. The loss from the second month then becomes 5.26 x $4 = $21, and so on.
