Why do stocks keep changing after hours?
This price volatility may be temporary as the market may capture spikes in price to resolve liquidity shortages of securities once regular trading hours have opened.
For each share they buy, an investor owns a piece of that company. In large part, supply and demand dictate the per-share price of a stock. If demand for a limited number of shares outpaces the supply, then the stock price normally rises. And if the supply is greater than demand, the stock price typically falls.
While many factors influence the stock market in the short term, in reality, the main reason the stock market goes up over time is that the economy is growing and companies are making more money.
The answer is that stock prices are indeed determined by supply and demand. If you see no change in price when you trade, it is because the amounts you are trading are relatively small. If you try to buy or sell a particularly large amount at one time you will indeed see the price move.
Some traders follow something called the "10 a.m. rule." The stock market opens for trading at 9:30 a.m., and the time between 9:30 a.m. and 10 a.m. often has significant trading volume. Traders that follow the 10 a.m. rule think a stock's price trajectory is relatively set for the day by the end of that half-hour.

Stock returns reflect new market-level and firm-level information. As Roll (1988) makes clear, the extent to which stocks move together depends on the relative amounts of firm-level and market-level information capitalized into stock prices.
If a stock falls to or close to zero, it means that the company is effectively bankrupt and has no value to shareholders. “A company typically goes to zero when it becomes bankrupt or is technically insolvent, such as Silicon Valley Bank,” says Darren Sissons, partner and portfolio manager at Campbell, Lee & Ross.
Trading during extended hours takes place when the major exchanges are closed, so orders are placed through computerized trading systems, or electronic markets.
Every time a block of shares is bought and sold, the stock price changes to reflect the latest transaction price. The sheer number of transactions ensures that the stock price fluctuates every second, even if there's been no change in market sentiment.
Do stocks usually go up or down after hours?
End-of-day trading tends to solidify the consensus established by action earlier in the day. Stocks that have been trending up typically keep rising, while stocks that have been tracking lower often plumb new depths. This is largely because end-of-day trading tends to be dominated by institutional investors.
A buy signal is given when price exceeds the high of the 15 minute range after an up gap. A sell signal is given when price moves below the low of the 15 minute range after a down gap. It's a simple technique that works like a charm in many cases.

We want to know if, from the current price levels, a stock will go up or down. The best indicator of this is stock's fair price. When fair price of a stock is below its current price, the stock has good possibility to go up in times to come.

What drives big moves in national stock markets? The benchmark view in economics and finance holds that stock price changes reflect rational responses to news about discount rates and cashflows.
Because relatively few people actually trade after the market closes, orders tend to build up overnight, and in a rising market, that will produce an upward price surge when the market opens. But during extended declines, overnight sell orders may cause prices to plummet when the market opens.
Yes, it's possible for a stock to increase by 100% or more overnight, but it's relatively rare and typically occurs under specific circumstances. For example, a company may announce positive news such as a major acquisition or successful clinical trial results, which can cause a sudden surge in the stock price.
Has a stock ever gone to zero?
Sometimes a company will be forced into bankruptcy and its stock fall to zero as the result of an accounting scandal or fraud. Take the famous case of Enron, a large and influential energy and trading company in the 1990s.
Can a stock ever rebound after it has gone to zero? Yes, but unlikely. A more typical example is the corporate shell gets zeroed and a new company is vended [sold] into the shell (the legal entity that remains after the bankruptcy) and the company begins trading again.
When the stock market declines, the market value of your stock investment can decline as well. However, because you still own your shares (if you didn't sell them), that value can move back into positive territory when the market changes direction and heads back up. So, you may lose value, but that can be temporary.
However, after-hours price changes are often more volatile than regular-hours prices, so they should not be relied on as an accurate reflection of where a stock will trade when the next regular session opens.
Some stocks may simply not trade after hours. No index values: Index levels generally aren't calculated or disseminated for public use after hours, which could pose a challenge for individual investors hoping to trade certain index-tracking products in the after market.
