Put it this way, a good investment is also a form of savings while just putting it in the bank is not really savings. Also, I think the management of money does not mean to 'save' it. Rather, it's the understanding of how to manage your income wisely. The general rule is 5:3:2, 50% on expenses, 30% investment and 20% on rainy day liquidity. So you can invest and save at the same time. Young people, without liability of dependents and have a stable job/income should always invest for growth at the start. Then they can transit to income based investment once they hit a certain threshold. Meanwhile, they should save, albeit a small amount every month for the rainy days / potential warchest when market goes down. So both can be done simultaneously.
We live in historic times! All the events of Gamestop $GameStop(GME)$ is eerily similar to the origin story of Bekshire Hathaway. Back in 1962, Bekshire was a fledging textile business on the verge of decline when Warren Buffett decide to invest in the business. Within a span of 6 years, he pivot the company from textile making core to a financial / insurance powerhouse. Now with the recent 2 billion USD raised in share sale, Ryan Cohen, with the blessings of Roaring Kitty aka Keith Gill, has the opportunity to recreate history and turn GME into a second Bekshire! This will be the company of the 22nd century!
Best to understand the companies (fundamentals) than blindly follow.. sometimes they buy and sell at different timings and if you did not copy in time, you might even get burnt!
