There is a reported dip in tech stocks ahead of SpaceX's initial public offering (IPO). Some experts, including Tom Lee, believe this dip will reverse after the IPO, with Lee also characterizing the sell-off as "healthy". However, others, such as Doug Kass, are less optimistic, and there are warnings of potential bear market-like moves in the second half of the year, with the SpaceX IPO lockup expiry cited as a possible headwind.
