““It’s been truly amazing,” said Brian Culpepper, a money manager at James Investment Research. “Everyone just thinks the stock market is going to go, go, go,” he added. “Whether it’s herd mentality, or fear of being left behind, that’s what you’re seeing.”
Dated from the last bear-market bottom, the boom cycle is young -- 11 months, versus five years for the median bull market. But its velocity makes up for the age. The S&P 500’s current peak-to-trough gain already eclipses three other full bull markets. If history is any guide, this one is likely more than half done as the median return of the 13 previous bull cycles was 126%”.

Hey, GameStop Traders, Buying to Push the Price Doesn’t Work

“The investment newbies who lost money speculating on GameStop Corp. shares made a classic mistake: They tried to push up the share price through their own purchases.
That did not work and never has, says Lasse Pedersen, a finance professor at Copenhagen Business School and a principal at AQR Capital Management, the big Greenwich, Conn.-based investment manager. He spoke in his academic capacity on Feb. 19 in a webinar hosted by Princeton University economist Markus Brunnermeier.
By buying shares to make them go up, you’re acquiring them at steadily higher prices. When you start to sell and your selling inevitably pushes the shares back down, your average sales price will be lower than your average purchase price, which is a long way of saying you will lose money, Pedersen said”.
