Gold majors have a big problem (Ad) Newmont spent 15 billion dollars acquiring Newcrest in 2023, the largest deal in gold mining history. Yet production stayed at 5.9 million ounces, unchanged from 2020. Newmont, Barrick and Agnico all face the same reserve shortage, pushing majors toward acquiring smaller producing miners. Recent deals show the pattern: Rupert Resources jumped 67 percent and G2 Goldfields jumped 79 percent the day their buyouts were announced. Analyst Garrett Goggin has identified four junior miners he believes are next on the shopping list. See the four junior gold miners flagged as potential buyout targets

This looks like plywood. It's not. (Ad) AI data centers have a power problem nobody likes to talk about. A single rack of computers can now use more electricity than an entire office building. One new chip, which looks more like a piece of plywood than a processor, delivers similar performance on a fraction of the power. Tech investing veteran George Gilder says that efficiency gap could decide who wins the next stage of AI. Gilder has identified three companies positioned around this power breakthrough, calling them the Trillion Dollar Triangle. See the three companies behind this AI power breakthrough now
