What happened

Shares of CrowdStrike Holdings (CRWD 3.63%) have fallen today, down by 6% as of 1:20 p.m. EDT, following reports that a large shareholder is looking to unload millions of shares. The news comes as the stock has more than tripled from its March lows, and has more than doubled year to date.

So what

A prominent shareholder is trying to arrange a deal with investment bank Barclays to sell 7.5 million shares at a price of $104 to $104.71, according to Bloomberg. Those prices would represent a modest discount to yesterday's close, but shares have since fallen below that range. It's unclear who the selling stockholder is.

Now what

When major shareholders are looking for an orderly way to cash out a large chunk of shares, it's not uncommon for them to work with investment bankers to set up an offering, to minimize potential disruptions to the market that could be caused by selling pressure. Now many investors just want to know who the selling shareholder is.
