The U.S. Financial Industry Regulatory Authority (FINRA) is warning retail investors that they may be getting in over their heads as the meme stock roller coaster continues. Dave Nadig, a financial futurist at ETF Trends, joined Cheddar News to give his thoughts on a proposal to create a kind of test to mitigate risky retail trading behavior and how it differs from existing qualifications for certain types of trading. "What FINRA was proposing is very different. They're actually talking about potentially testing investors to see whether they understand more complex products," he said. "And so this is a very new and I think slightly dangerous proposition from regulators."
