If you’ve been watching the stock market closely this year, you’ve probably noticed it feels a lot like riding a roller coaster. One week stocks are skyrocketing; the next they’re plummeting.
This kind of volatility isn’t random. Since mega-cap stocks like Nvidia, Microsoft, Apple, and Amazon drive much of the overall market’s performance, investors are keeping a close eye on them.

With so much attention on these mega stocks, here are three volatility predictions for the rest of 2025 and what it means for your investments.
Stock Prices Are High and That Makes Them Volatile
Right now, many of the mega companies on the stock market are trading at very high prices compared to their earnings, meaning they have high price-to-earnings (P/E) ratios. A high P/E ratio means that investors are willing to pay a premium for a company’s stock due to strong future growth expectations.
While this is not a bad thing, it means that such stocks are vulnerable to bad news. If Apple, Nvidia or any other mega-cap stock misses earnings even by a small amount, the stock price can drop much more sharply than it would if expectations were lower. And since most mega-cap stocks make up a huge portion of the overall market, especially the S&P 500 and Nasdaq, their volatility ends up affecting everyone.

The Fed Isn’t Cutting Interest Rates
Many investors expected the Federal Reserve to lower interest rates, but that hasn’t happened. The Fed is holding rates steady in the 4.25% to 4.50% range due to inflation and tariff uncertainty. This has a big effect on the stock market, especially tech and growth stocks.
High interest rates make borrowing expensive. That can slow down innovation for mega companies or delay new projects. Plus, when rates stay high, investors are more likely to move money out of stocks into safer investments like bonds and high-yield savings accounts. That shift can lead to more stock selling and more volatility overall.
Uncertain Tariff Policies
Earlier this year, President Donald Trump imposed tariff policies on several imported goods. While tariffs don’t impact stocks directly, stocks often drop whenever a new tariff policy hits the headlines. This is because investors are worried about supply chain disruptions, higher costs for businesses and slower global growth.
Such trade policy changes can lead to volatility in the stock market. And for mega companies like Apple, which relies heavily on overseas manufacturing, headlines about trade policies can move prices even if company fundamentals look strong. This is especially true for mega-cap stocks that have economic influence.
