Ex-TD Ameritrade CEO warns meme stock traders that leverage could ‘rip your arms off’

Joe Moglia, former CEO of online trading platform TD Ameritrade, issued a stern warning Thursday about using leverage to try to outsize returns in meme stocks.

“My biggest concern is what’s going on with the individual investor” using borrowed money to trade more than they have, Moglia told CNBC’s “Squawk Box,” as AMC Entertainment shares whipsawed in early trading and dropped some 30% shortly after the open on Wall Street.

AMC nearly doubled in the prior session. Its year-to-date gain today, despite the sharp pullback Thursday, is about 2,200%.

Another Reddit favorite, BlackBerry, soared about 13% on Thursday after closing up nearly 32% in the prior session. Bed Bath & Beyond, also caught up in the meme stock mania, fell 25% after soaring 62% on Wednesday.

“They got to be able to understand when they use leverage what that really means. Leverage on the way up is a great thing. Leverage on the way down can rip your arms off,” added Moglia, currently Capital Wealth Advisors chairman.

The wild swings in AMC on Thursday started after the movie theater chain filed to sell 11.55 million shares “from time to time.” As a disclosure, AMC said, “We caution you against investing in our Class A common stock, unless you are prepared to incur the risk of losing all or a substantial portion of your investment.”

AMC revealed Tuesday in a securities filing that it raised $230.5 million in a stock sale to depressed debt firm Mudrick Capital Management, which reportedly sold those new AMC shares immediately for a profit.

With meme stock prices and headlines about the companies’ businesses moving quickly, brokerages —particularly those catering to individual investors — need to do a better job of educating their clients about the risks of what seems like an easy way to make money and when to sell, Moglia said.

“For example, if you bought AMC at $10 and its goes to $20, is that not enough of a profit? If it goes to $30, $40, at what time do you start to trim that position or in effect get rid of that position altogether. We have to do a better job with the day-traders,” he added.
