Earnings reports and management guidance can alter expectations for a company; political or broader market events can affect it too. Sentiment may influence trading interest, while demand and available liquidity help determine the prices at which orders execute. None of these factors guarantees a move in a particular direction or by a particular amount.
How a stock price changes during the day
A stock’s quoted price reflects trading: buyers and sellers submit orders, and trades occur when orders meet. New information can change what investors are willing to pay or accept. The U.S. Securities and Exchange Commission (SEC) notes that a stock can be affected by events inside the company, such as a faulty product, as well as events outside its control, including political or market events. SEC Investor.gov: Stocks – FAQs.
That means a price move is not, by itself, an explanation. To assess one, separate the information that became available from the conditions under which orders were placed. The market’s reaction also does not prove that its interpretation of the information was correct.
What earnings reports and guidance tell investors
Earnings report: what happened
Public companies disclose information about their financial performance through reports and other filings. Earnings results describe performance over a reporting period; they are backward-looking information about what the company reported. The SEC’s overview explains how public companies provide information to investors through required disclosures: SEC Investor.gov: Public Companies.

Guidance: what management expects
Guidance communicates management’s expectations about future performance and the assumptions behind them. It is not the same as a reported result, and it is not a guarantee of future performance. An earnings announcement may include updated guidance, giving investors both results for the period and a revised view of what management expects next.
Investors may reassess a company when results or guidance differ from what they expected. But there is no reliable rule that an earnings “beat” makes a stock rise, or that lower guidance makes it fall. The direction and size of a response are not established by the figures alone; other information and trading conditions also matter.

A dated example of guidance
In an SEC-filed release dated July 30, 2026, Illinois Tool Works said it was raising its 2026 GAAP EPS guidance by $0.15 and narrowing the range to $11.35–$11.55 per share. It also raised its revenue-growth guidance to 4–5%. These figures describe that company’s announcement, not a general measure of how guidance affects share prices: Illinois Tool Works, second-quarter 2026 results and guidance.
How sentiment can influence trading—and why to be cautious
Market sentiment refers to how investors appear to feel about or position themselves around information. Social media can spread genuine company news, but posts can also be false or misleading. Sentiment tools may draw on social-media discussion and other information, so their signals should not be treated as a reliable substitute for company disclosures or independent analysis.

The SEC and FINRA warn investors not to rely solely on social-sentiment tools. The SEC also warns that short-term trading based on social-media attention can expose investors to significant risks. Review the guidance in the SEC and FINRA bulletin on social-sentiment investing tools and the SEC alert on short-term trading based on social media.
Why the last-traded price may not be your execution price
The price displayed as the last trade is not a promise that a new order will execute at that price. According to the SEC, a market order seeks the best available price, but the actual execution depends on demand and available liquidity. Prices can change before an order reaches the market, and a large order may fill in multiple parts at different prices. See SEC Investor.gov: Understanding Order Types.

This distinction matters when explaining an intraday move: a chart’s last price is a record of a past trade, while a buyer or seller faces the available orders and liquidity when placing a new order.

- Identify what became public. Check company filings and releases for earnings, guidance, or other company developments; then consider whether political or broader market events may also be relevant.
- Separate reported performance from expectations. Note what the company reported for the period and what management said about future performance, including any stated assumptions.
- Distinguish disclosure from discussion. Treat official company information differently from social posts or sentiment indicators, which may be incomplete or misleading.
- Consider trading conditions. The last trade does not establish the price available for a later order; demand, liquidity, intervening orders, and order size can affect execution.
These checks help organize the evidence; they do not establish that any one factor caused a move or predict what a stock will do next. No broadly applicable authoritative statistic establishes a typical intraday price effect for earnings, guidance, or sentiment across stocks.
