After years of standing in the sun, retail investors could have a dark cloud forming over their heads.

Technological advancements helped level the playing field for Main Street and Wall Street investors over decades. Following the Covid trading boom and a banner performance in 2025, individual investors became a mainstay of today's markets and shook off their "dumb money" stigma.

But advocates for small investors now warn that efforts to change corporate earnings, Federal Reserve communication and social media access could undo a sizable chunk of that progress. These shifts would disadvantage retail investors at a time when they are a more powerful force than ever in financial markets.

"We are almost taking steps backwards," said Hardika Singh, economic strategist at asset manager Fundstrat. "It's almost making me wonder: Are we sort of entering this information blackout age for a very important subset of the stock market?"

There's three key storylines market participants are tracking that could hurt the retail crowd:

The Securities and Exchange Commission in May backed President Donald Trump's proposal for public companies to report earnings biannually instead of quarterly. SEC Chairman Paul Atkins said in a statement that the organization's "rigid" rules have stopped companies from finding a reporting cadence that "best serves their business needs."

Investors acknowledge that required quarterly reports can strain corporate resources and keep firms from going public. But having less of these audited releases could result in an information vacuum for retail investors, according to Siebert Financial's Mark Malek. More unofficial content or misinformation could arise as a result, he said.

Quarterly earnings reports are "the gold standard," said Malek, the firm's investing chief. "Taking that away is definitely disadvantaging the retail investor."

In a poll on retail investing platform Moomoo, U.S. CEO Neil McDonald found that most users disliked the prospect of switching to a twice-yearly reporting cycle. If retail investors have less-frequent insight into financial performance, McDonald said that they would likely become more hesitant to invest in small-cap, high-growth companies.

McDonald remembers working at Goldman Sachs in the 1980s when analysts would jet off to a company's headquarters to collect earnings reports. The analyst would dictate the results by phone, allowing the bank to quickly alert its institutional clients. A retail investor likely wouldn't know how the company performed until the newspaper arrived a day later, he said.

Wall Street has a history of using unconventional mechanisms when official information is difficult to find. Before the SEC mandated quarterly earnings in 1970, firms tracked data like weekly rail car loadings for clues on the direction of economic activity. When China was a black box for American investors, traders followed coal shipments to the country as a leading indicator for production.

If there are fewer earnings reports, institutional investors will be able to lean on their teams of analysts, who often have direct access to a company's C-suite. Small-scale investors, on the other hand, typically only hear directly from these executives by listening into earnings calls or tracking their public appearances.

"The chief financial officer is not likely going to take a call from Joe Blow," said Sam Stovall, chief investment strategist at CFRA Research, whose firm advertises services for both big and small investors. "But they would take a call from a very high-profile institutional investor."

New Fed Chairman Kevin Warsh has cut down the central bank's policy meeting statement and removed forward guidance. Warsh, who has promised sweeping changes in how the Fed communicates, also floated the idea of having fewer of these gatherings.

Hearing less from the Fed can make it harder for retail to set expectations for the economy and monetary policy, which can be important factors when deciding overall portfolio allocation. Additionally, small investors have a penchant for technology stocks whose growth outlooks are dependent in part on borrowing costs determined by the Fed.

Markets have already had less clear of a consensus heading into the first two Fed meetings under Warsh when compared against recent history. With less policy hints from the Fed, investors anticipate more volatility after policy decisions are announced.

Wall Street firms have built out artificial intelligence-powered tools to keep a handle on the Fed in the lower-communication environment. Several of these institutions have economists — and, in many cases, Fed alumni — on staff to predict what the central bank's next move could mean for markets.

If the macroeconomic picture becomes harder to gauge, CFRA's Stovall said small investors may look to financial advisors for help.

Truth Media & Technology Group's launch of Truth API — a paid data service providing faster access to Truth Social posts — heightened the concern of retail investors having the cards stacked against them.

Kevin McGurn, Trump Media's interim CEO, said in a statement around its release this month that the API provides "a direct, licensed, real-time feed of the platform's most market-moving Truths." Trump Media did not respond to CNBC's questions about the cost of the offering or how early of access it offers.

Multiple of the S&P 500's best and worst days during Trump's second term have been driven by posts he made on Truth Social, a Fundstrat data analysis found.

"He has the market in the palm of his hands," said Fundstrat's Singh. "Never before in history has a president exerted this level of control via social media."

Several investors told CNBC that Trump is incentivized to make more market-moving Truth Social posts to drum up interest in the API. Trump's family is the largest shareholder in Trump Media, which reported more than $230 million in net losses during the second quarter.

Siebert's Malek likened Truth API to the push among big trading firms in recent years to move their servers closer to those of exchanges. The idea was that the proximity would allow them to get information even a few milliseconds before competitors, resulting in earlier trades, he said.

Malek said Siebert isn't planning to pay for access to Truth API. However, he said the offering should provide an advantage for big investors looking to time the market.

There's a silver lining for long term-focused retail investors who can handle increased volatility, according to Douglas Yones, CEO of exchange-traded fund manager Direxion. If Trump's future posts drive down the market, he said retail investors will have additional opportunities to buy pullbacks in equities.

"You don't need to subscribe to that API," said Yones, a former executive at the New York Stock Exchange. "What you need to do is be ready for the outsized movement."

Even if big money ends up with the upper-hand, market participants said they should still be concerned if retail traders are cast out.

Retail investors have been credited with fearlessly loading up on stocks in recent years, providing a baseline of inflows that has helped the current bull market become one of the longest on record. Individual investors bought the dip during 2025's tariff-related market selloff while their institutional counterparts ran for the hills.

Singh said that having a higher number of retail investors in the market allows for better "price discovery," meaning that values attributed to a security are more fairly determined. If these changes take effect, the strategist said the broader market could feel negative ramifications as soon as this year.

But even with these potential speed bumps, Bret Kenwell, eToro's U.S. investment analyst, expects retail to continue taking up a bigger slice of the overall pie. The stage is set for this year: Citadel found that overall activity among individual traders hit a record in June.

"I don't think any of these developments would be enough to drive retail investors out of the market," Kenwell said. "It's a question of whether it remains a level playing field for them."
