This week on Prof G Markets, we open with how the mutiny in Russia might impact the global markets. Scott then shares his thoughts on why the U.S. housing supply is so constrained, and what to do about it. He also discusses the package delivery market and what might happen if one of its largest players goes on strike. And finally, he takes a look at the run-up in Adobe’s stock after announcing its AI product, Firefly. Scott also discusses what the tragedy of the OceanGate submersible means for another extreme tourism company, Virgin Galactic, which is set to launch its first revenue-generating flight this week.
