I've been watching money market yields for the last several months as interest rates have skyrocketed. I compare the 7 day yield of my money markets at Fidelity, T Rowe Price and Vanguard to see where the best "bang for the buck" exists.
Hopium stocks are stocks that are losing a great deal of money while they try to get sufficient scale to be profitable. It's generally the startup mentality. You can really win big if it scales to profitability, like Amazon. Unfortunately, less than 1 in 1000 are able to become big winners. T
