Blank sees a record profit margin that is going to be eroded thanks to rising labor, material and trucking costs. At the same time, the hurdles become higher for internal capital investment allocations that can add more to a record profit margin, he explained.
Therefore, the default is more share buybacks, he said.
However, he stressed that whether this is a peak earnings year is impossible to know in advance, only in hindsight. He said he thinks the forward-looking calculus is tough to ignore.
“It is better to accept it. Stocks can advance for a few more months, and then roll over, foretelling the peak that is just over the horizon,” he said.
Meanwhile, Kevin O’Leary, chairman of O’Shares ETFs and co-host of “Shark Tank,” thinks companies just shouldn’t do buybacks.
“I hate buybacks,” he said on “Closing Bell.”
For one, companies are bad at timing — right now they would be buying them at the highs, he said.
Plus, “I like to put my money to work where I want to. I don’t necessarily want to take my portions of the profits of XYZ Corp. and have the management decide that I should buy more shares,” O’Leary added.
He’d prefer cash be returned to shareholders in the form of dividends.
