I've invested for my own account over 50 years, and served as a NASD/FINRA arbitrator over 20 years. I dealt with options, high-yield funds, leveraged ETFs, and many other products. My concerns are disclosures and suitability.
Complex products require complex rules and complex disclosures. Disclosures must have a separate summary of risks in plain language, in addition to the legal language required. Additional rules and policies a member/seller may have (beyond those of FINRA or the SEC) need to be spelled out clearly, again in a separate section.

I have seen warning provided by the broker website on each buy trade. In addition I had to go through a risk signup document to confirm that I understand the risk.
Above steps are good way to provide disclosure on every trade.
However if the changes are being planned to make an investor go through certain tests then I think that is excessive, and would not appreciate putting such restrictions.

I use leveraged ETFs everyday and am well aware of the risks involved. Pulling retail access from them cripples the idea of a free market. Removing them does not make the market any less risky for retail investors, there are plenty of retail investors who have lost it all on worthless meme stocks such as $GME. This proposal makes no sense once its thought out and reduces 0 risk.

Comments: As a retail investor that wants to take advantage of leverage without the use of options these instruments work to add exposure for a long or as a hedge on sector/market downturns.

I would say that most retail need to understand how they work in reality (rebalancing every day) and the risks associated during times of high volatility. In that case it's the same issues as having options.

Please do not limit access to leveraged ETFs. At the most, perhaps a full disclosure from brokers regarding them could be helpful. Lets try to get the playing field between institutions and retail traders equal.

I should be able to make my own choice as related to investing. My Money My Choice.

I do not want any government touching my cryptocurrency , or regulating what I can buy and can't buy!

There is no need for FINRA to deny or block regular investors from investing in leveraged funds or complex products. I have been investing in them for years with no issues. The only thing FINRA should do is make illegal "naked" shorting of securities, commodities, or bonds. Naked shorting only serves the purpose of taking companies down or destroying commodities prices. Why this was ever allowed in the first place is beyond me. So please keep out of leveraged funds but please make illegal all naked shorting.

Regulations, can be made to make commerce safer for the consumer, as it can also be made to subvert competition in the market place. For too often, government has lent its hand, on the balance of trade, to favor some businesses over others, strictly for the favors of the favored. Time, for government to deal out real fairness in commerce, and to truly uphold the Constitution as written.
